Crypto fees are payments to blockchain miners or validators that ensure secure and efficient transaction processing. They include transaction fees, gas fees, exchange fees, and DeFi costs. Learn how fees are calculated, factors affecting them, and strategies to reduce costs using Layer 2 solutions, batching, and optimized wallets for faster, cheaper blockchain transactions.
You just sent $50 worth of crypto to a friend and paid $12 in fees. Or you tried to mint an NFT and watched the gas estimate climb past $80 before you gave up. If either of those scenarios sounds familiar, you are not alone — and the frustration is completely understandable.
Crypto fees are one of the most practical things to understand if you are doing anything on a blockchain. They determine whether a small transfer makes economic sense, which network you should use for a DeFi trade, and why the same action can cost $0.001 on one chain and $30 on another.
This guide explains everything — what fees are, why they exist, how they are calculated on different blockchains, what is actually happening with fees in 2026, and the most effective strategies to reduce what you pay.

1. What Are Crypto Fees? (And Why They Exist)
Crypto fees are payments made by users to the validators or miners who process and confirm transactions on a blockchain. Every time you send cryptocurrency, trade on a decentralized exchange, interact with a smart contract, or mint an NFT, a fee is attached to that action. That fee goes to the network participants who verify your transaction and add it to the blockchain.
The simplest way to think about it: fees are the cost of using a decentralized network that has no central company to absorb infrastructure costs. In traditional banking, Visa charges merchants a percentage per transaction and uses that revenue to maintain its network. In crypto, the network participants who do that processing work — miners in Proof-of-Work systems, validators in Proof-of-Stake systems — earn fees directly from users.
Why fees exist comes down to four things:
Fees reward validators and miners for the computational work and capital they commit to securing the network. Without this incentive, rational participants would not run nodes, and the network would have no one to process transactions. Fees also prevent spam — if transactions were free, flooding a blockchain with thousands of meaningless transactions would cost nothing, making denial-of-service attacks trivial. Additionally, fees create a prioritization system: when a network is congested, users who need faster confirmation can pay more to get it, while those who are patient can wait and pay less. Finally, in Proof-of-Work systems where block rewards are declining over time (as in Bitcoin’s halving schedule), fees are increasingly important for maintaining long-term miner incentives as new coin issuance decreases.
2. Types of Crypto Fees Explained
Not all crypto fees are the same thing. The word “fee” covers several distinct charges depending on what you are doing and which platform or blockchain you are using.
Transaction Fees
Transaction fees are the base fee paid to miners or validators for including your transaction in a block. They are the most fundamental type of fee and exist on virtually every blockchain. On Bitcoin, transaction fees are measured in satoshis per byte of transaction data — a straightforward model where larger transactions in bytes cost more, regardless of the dollar value being transferred. Sending 0.001 BTC and 100 BTC at the same time, using the same transaction structure, costs the same in network fees.
Network Gas Fees
Gas fees are the version of transaction fees used on smart contract blockchains — Ethereum being the primary example. The term “gas” reflects the idea that computational operations consume resources, just as a car burns fuel. Every action on Ethereum — sending ETH, swapping tokens on Uniswap, depositing into a DeFi protocol — consumes a specific amount of gas. Complex operations consume more gas than simple transfers.
The total gas fee you pay is: Gas Used × Gas Price (in Gwei). A simple ETH transfer uses 21,000 gas. A token swap on a DEX might use 150,000–300,000 gas. Deploying a smart contract can use millions of gas units. Gas price fluctuates based on network demand, which is why the same swap can cost $2 during quiet periods and $50 during a popular token launch.
Exchange Fees
Exchange fees are separate from blockchain network fees and are charged by the platform — centralized or decentralized — where you trade.
Centralized exchanges like Binance and Coinbase charge trading fees (typically 0.1–0.5% of the trade amount) and withdrawal fees (a fixed charge for moving crypto off the platform). These fees go to the exchange, not the blockchain network. Decentralized exchanges like Uniswap charge liquidity provider fees — usually 0.05–1% per swap depending on the liquidity pool tier — plus the underlying blockchain gas cost.
One important distinction: when you trade on a CEX and then withdraw, you pay both a trading fee and a separate withdrawal fee. The withdrawal fee is the exchange’s estimate of the blockchain network fee, sometimes with a margin built in.
DeFi Protocol Fees
DeFi platforms charge fees for using their specific services. Lending protocols like Aave and Compound apply interest rate spreads — the difference between what borrowers pay and what depositors earn. Automated market makers take a percentage of each swap for their liquidity providers. Yield aggregators charge performance fees on the returns they generate. These protocol fees are usually denominated in the token being traded or the yield being generated, and they are separate from the gas cost of executing the transactions.
Summary at a Glance
| Fee Type | Who It Goes To | Example |
|---|---|---|
| Transaction / Gas Fee | Miners or validators | Sending BTC or ETH |
| Exchange Trading Fee | The exchange platform | Buying BTC on Binance |
| Exchange Withdrawal Fee | Exchange (covers network cost + margin) | Withdrawing BTC from Binance |
| DeFi Protocol Fee | Liquidity providers or protocol treasury | Swapping tokens on Uniswap |
| Bridge Fee | Bridge operators + source chain gas | Moving ETH from Ethereum to Polygon |
3. How Crypto Fees Are Calculated
Understanding the calculation behind fees removes most of the mystery — and helps you understand why fees change so dramatically from one moment to the next.
Fixed vs Dynamic Fees
Some older or simpler blockchains use fixed fee models where the cost per transaction is predetermined regardless of network conditions. These are simple to understand but create problems when demand spikes — because fees do not rise automatically, users have no mechanism to “bid” for faster confirmation, and congestion simply creates delays for everyone equally.
Modern blockchains use dynamic fee models that adjust automatically based on demand. Ethereum’s EIP-1559 model, introduced in 2021, is the most influential example and has been widely replicated. It splits fees into two components: a base fee that adjusts automatically with each block based on how full the previous block was, and a priority fee (also called a tip) that users can optionally add to incentivise validators to prioritise their transaction. Critically, the base fee is burned rather than paid to validators — removing it from circulating ETH supply permanently.
The Ethereum Gas Fee Calculation
For a simple ETH transfer with these parameters:
- Gas limit: 21,000
- Gas price: 50 Gwei
- ETH price: $3,000
The fee calculation runs as follows:
21,000 × 50 Gwei = 1,050,000 Gwei = 0.00105 ETH
At $3,000 per ETH, that is approximately $3.15 for a basic transfer. Now imagine the same calculation during a major NFT drop when gas prices spike to 350 Gwei — the same basic transfer suddenly costs over $22. This is why checking current gas prices before transacting on Ethereum mainnet matters, particularly for smaller transactions where the fee could represent a meaningful percentage of the total value being moved.
What Drives Fee Changes
The primary driver is network congestion — how many transactions are competing for limited block space at any given moment. Bitcoin processes roughly 7 transactions per second at maximum capacity; Ethereum mainnet handles around 15. When more users want to transact than those limits allow, a bidding war for block space develops and fees rise.
Transaction complexity matters too. A simple transfer is cheap because it requires minimal computation. A multi-step DeFi interaction — deposit collateral, borrow a stablecoin, swap it for another token, provide liquidity — executes multiple contract calls and can cost hundreds of thousands of gas units.
Time of day has measurable impact, particularly for Ethereum. Network activity tends to be lower during early morning UTC hours on weekdays and throughout weekends. Users who can be flexible about timing can meaningfully reduce what they pay.
4. Crypto Fee Mechanisms on Major Blockchains
Bitcoin Transaction Fees
Bitcoin’s fee model is based on transaction size measured in virtual bytes (vBytes), not the value being transferred. Miners prioritise transactions by fee rate — satoshis per vByte — meaning a large transaction with many inputs needs to pay a proportionally higher total fee to achieve the same priority as a small clean transaction.
SegWit (Segregated Witness) transactions are structurally smaller in vBytes than legacy transactions, which directly reduces fees for users who use SegWit-compatible addresses (addresses starting with “bc1”). During quiet network periods, a Bitcoin transaction can cost under $1. During peak congestion — market panic, major exchange activity, or a new token launch on Bitcoin’s Ordinals protocol — fees can spike to $30–$50 or more.
Ethereum Gas Fees in 2026
Ethereum mainnet average fees in 2025 settled at approximately $3.78 per transaction, down from around $5.90 in March 2024. That improvement reflects the cumulative impact of EIP-1559, Layer 2 migration, and the Dencun upgrade (EIP-4844), which introduced “blob transactions” that drastically cut the cost for Layer 2 solutions to post data to Ethereum mainnet. EIP-4844 alone reduced L2 data posting costs by 50–90%, which in turn lowered the fees end users pay on L2 networks.
That said, Ethereum mainnet congestion spikes still happen. During a major NFT drop in February 2025, gas fees jumped to 350 Gwei, pushing a simple transaction back toward $7 and a complex DeFi interaction past $50. EIP-1559 improved fee predictability significantly — about 78% of transactions now experience fee variations within 15% of expected costs — but it did not eliminate congestion pricing during exceptional demand events.
Layer 2 Networks: The Real Story in 2026
This is where the most meaningful change in crypto fees has happened. Layer 2 networks process transactions off Ethereum mainnet by bundling hundreds or thousands of transactions together, executing them off-chain, and posting a single cryptographic proof back to Ethereum. The result is that users get Ethereum’s security at a fraction of the cost.
The numbers are striking. L2s now typically charge under $0.01 per transaction, compared to L1 mainnet spikes of $5–$50 during congestion. Ethereum mainnet’s average fee of $3.78 effectively functions as a migration trigger — when mainnet fees exceed that threshold, users shift to L2 alternatives. By 2026, forecasts suggest up to 80% of all Ethereum-related transactions will occur on Layer 2 solutions, with the mainnet primarily handling settlements and security anchoring.
Practical fee comparison for common actions:
| Action | Solana | Polygon | Arbitrum | Avalanche | Ethereum L1 |
|---|---|---|---|---|---|
| DeFi Swap | ~$0.001 | ~$0.02 | ~$0.03 | ~$0.05 | $5–$50 |
| NFT Mint | ~$0.005 | ~$0.10 | ~$0.05 | ~$0.20 | $50–$150 |
| Staking | ~$0.001 | ~$0.01 | ~$0.02 | ~$0.03 | $10–$30 |
Alternative High-Throughput Blockchains
Solana processes thousands of transactions per second and charges fees of a fraction of a cent per transaction under normal conditions. Its architecture is fundamentally different from Ethereum — rather than a fee market based on block space competition, Solana uses a fixed minimum fee with a priority fee mechanism for time-sensitive transactions. The tradeoff is that Solana has experienced notable network outages that Ethereum’s more conservative architecture has avoided.
Binance Smart Chain (BSC) offers EVM compatibility at very low fees, though its validator set is considerably more centralised than Ethereum or Bitcoin. Avalanche offers customisable subnets with low fees and fast finality. Polygon remains a widely-used lower-cost environment for DeFi and NFT activity, particularly for applications that need Ethereum compatibility without Ethereum mainnet costs.
5. Real-World Crypto Fee Examples in 2026
Seeing fees in context of actual transactions makes the abstract concrete.
Sending Bitcoin peer-to-peer
Transferring 0.5 BTC to a friend during low network activity costs between $1–$3. The same transfer during a peak period — say, immediately after a major market move when many people are moving funds simultaneously — can cost $30–$50. Using a SegWit address and setting a custom fee through a wallet like Electrum lets you choose your confirmation speed and adjust the cost accordingly. There is no compelling reason to overpay for a non-urgent transfer.
Swapping tokens on Ethereum mainnet
A $500 ETH-to-USDC swap on Uniswap during normal network conditions costs roughly $5–$15 in gas. During a major market event or a viral token launch, that same swap could cost $50–$100. The economics here matter: paying $10 to move $500 is a 2% fee, which is reasonable. Paying $80 to move $500 is a 16% fee, which makes the transaction economically irrational for most purposes.
The same swap on Arbitrum
That $500 ETH-to-USDC swap on Arbitrum, Ethereum’s leading Layer 2, costs approximately $0.03–$0.10. The transaction takes seconds, it is secured by Ethereum’s mainnet, and the user saves $5–$80 depending on timing. If you are regularly swapping on Ethereum mainnet in 2026 without a specific reason to do so, you are paying significantly more than necessary.
Minting an NFT
On Ethereum mainnet during high traffic, minting a single NFT can cost $70–$150 in gas. On Polygon, the same mint costs under $0.10. Most NFT projects that launched in 2023 or later have moved to L2 solutions or alternative chains for exactly this reason — $100 gas fees for a $50 NFT are a product problem, not just a user inconvenience.
Borrowing on Aave
Depositing collateral and opening a loan position on Aave’s Ethereum deployment costs $10–$30 in gas depending on complexity and timing. On Aave’s Polygon deployment, the same operation costs under $0.05. The protocol’s functionality is identical across deployments; only the underlying chain’s fee structure differs.
Withdrawing from a centralised exchange
Binance charges a network fee for withdrawals that covers the blockchain transaction cost plus a small margin. For Bitcoin withdrawals, this is currently around 0.0005 BTC. For ETH withdrawals, it varies by network — withdrawing to Ethereum mainnet costs more than withdrawing to Polygon or Arbitrum, which most major exchanges now support as withdrawal destinations.
6. How Fees Affect Users and the Network
The User Perspective
High fees create real economic barriers. A $20 gas fee makes a $50 DeFi transaction economically questionable. A $100 NFT mint during peak hours is a product experience that drives users to alternative platforms. For users in emerging markets where $5–$20 represents meaningful spending power, Ethereum mainnet fees during congestion have historically made participation simply unaffordable.
This is the social cost of Ethereum mainnet congestion that Layer 2 solutions are addressing. Before L2s became accessible and reliable, Ethereum felt like a club for users who could afford to participate during expensive periods. The drop in L2 fees has changed this: someone in Kenya can now trade tokens for less than a penny, and the financial accessibility of DeFi is genuinely different from what it was two or three years ago.
Transaction timing flexibility is a meaningful cost lever. Users who can wait — running non-urgent transfers at 3am UTC on a Sunday rather than during the US trading day — can consistently pay 30–60% less in gas fees on Ethereum, and similarly lower fees on other congestion-sensitive networks.
The Network Perspective
Fees perform a security function that is easy to overlook: they make attacks expensive. Spamming a blockchain with thousands of useless transactions costs money proportional to the network’s congestion. Free transactions would make denial-of-service attacks trivially cheap to execute.
The fee-burning mechanism in Ethereum’s EIP-1559 creates an additional economic dimension. When network activity is high, base fees are high and more ETH is burned — reducing circulating supply at the moments when the network is most in demand. This creates a deflationary pressure that links ETH’s economic model directly to network usage, which was a deliberate design decision with significant implications for long-term token economics.
Miner and validator incentives also depend on fees. As Bitcoin’s block reward continues to halve on its approximately four-year schedule — the next halving reduced the subsidy to 3.125 BTC per block in 2024 — transaction fees become progressively more important to miner economics. A future where Bitcoin transaction fees are insufficient to incentivise mining at current hash rates would be a genuine security concern, which is part of why Bitcoin’s long-term fee economics are a topic of active research and discussion.
7. Eight Proven Strategies to Reduce Crypto Fees in 2026
1. Move to Layer 2 Solutions for Ethereum Interactions
If you are regularly doing DeFi, NFT, or token activity on Ethereum mainnet and not using Layer 2 solutions, you are significantly overpaying. Arbitrum, Optimism, Base, and zkSync all offer sub-cent transactions for most operations while inheriting Ethereum’s security guarantees. The initial bridging cost — typically $1–$5 for the mainnet-to-L2 transfer — pays back within a handful of transactions.
The practical setup: bridge your ETH to your chosen L2 once, keep a small ETH balance on mainnet for future bridges or mainnet-specific operations, and do your day-to-day activity on L2. Most major DeFi protocols — Uniswap, Aave, Compound, Curve — have deployments on the major L2 networks.
2. Time Transactions for Low-Congestion Periods
Network fees on Ethereum and Bitcoin fluctuate significantly by time of day and day of week. Ethereum gas prices are typically lowest during early morning UTC hours on weekdays and throughout the weekend. Tools like Etherscan Gas Tracker and Blocknative show current gas prices and recent trends, letting you quickly assess whether now is a reasonable time to transact or whether waiting a few hours would save meaningful cost.
For non-urgent Bitcoin transactions, setting a low custom fee and accepting a longer confirmation window — 6–24 hours rather than the next block — can cut fees by 50–80% during periods of moderate congestion.
3. Use SegWit or Taproot Addresses for Bitcoin
SegWit (bc1q…) and Taproot (bc1p…) addresses produce structurally smaller transactions in vBytes compared to legacy Bitcoin addresses. Smaller transaction size means lower fees at the same sat/vByte rate. Most modern Bitcoin wallets — Electrum, BlueWallet, Bitcoin Core — default to SegWit addressing. If your wallet is still generating legacy addresses starting with “1”, switching to a wallet that supports SegWit will reduce your Bitcoin transaction fees on every send.
4. Batch Transactions Where Possible
Rather than sending five separate transactions — five separate fees — combine them into one where the operation supports it. Exchanges that process multiple withdrawals batch them on-chain. Some DeFi aggregators and portfolio management tools allow batching multiple protocol interactions into a single transaction. Paying one larger fee is almost always cheaper than paying five small ones when those five each carry a base cost.
5. Use Fee Estimation Tools Before Confirming
Overpaying for gas is extremely common and entirely avoidable. MetaMask, Rabby, and other modern Ethereum wallets display fee estimates based on current network conditions and give you options ranging from economical to fast. Etherscan’s Gas Tracker shows real-time gas prices and historical patterns. For Bitcoin, mempool.space provides a live view of current fee rates and recommended fees for different confirmation targets. Checking these before submitting a transaction takes thirty seconds and can save significant money.
6. Choose the Right Blockchain for the Job
Not every transaction needs Ethereum’s security model. Stablecoin transfers between wallets you control, small DeFi positions, and casual NFT activity do not require mainnet. Polygon, Solana, and BSC all offer sub-cent fees for standard operations. The appropriate strategy is matching your security and decentralisation requirements to the cheapest network that meets them — not defaulting to the most expensive option out of habit.
7. Avoid Unnecessary Smart Contract Complexity
Multi-step DeFi operations — flash loans, multi-hop swaps, complex yield strategies — consume substantially more gas than simple transfers. If your DeFi strategy requires stacking six different protocol interactions in a single transaction, the gas cost reflects that complexity. Breaking operations into separate simpler transactions, while sometimes less gas-efficient in aggregate, can improve the economics when mainnet fees are high. On L2s, this matters much less, but it remains relevant for mainnet interactions.
8. Monitor Fees With Alerts
Set gas price alerts through tools like Blocknative’s notification system or Ethereum Gas Station. These tools can send you a notification when gas drops below a threshold you define, allowing you to execute your planned transaction when conditions are favourable rather than checking manually at random intervals.
8. Common Misconceptions About Crypto Fees
“Fees are arbitrary.” They are not. Fees on every major blockchain reflect supply and demand for block space, which is governed by transparent, algorithmic rules. Understanding the fee mechanism for a given blockchain makes fee behaviour predictable in the general case, even if exact amounts fluctuate.
“Paying more always gets you faster confirmation.” Higher fees improve priority in the mempool, but during extreme congestion, even high-fee transactions can be delayed by block space limits. Fee estimation tools account for this by recommending fees based on current mempool depth, not just by a simple “higher is faster” model.
“All fees go to blockchain developers.” Transaction fees on Bitcoin go entirely to miners. On Ethereum, the base fee is burned (destroyed), and only the priority fee goes to validators. Protocol development is funded by separate mechanisms — grants, foundation treasuries, pre-mine allocations — not transaction fees.
“High fees make crypto unusable for small transactions.” On Ethereum mainnet, that was genuinely true during peak congestion periods. On Layer 2 networks and alternative chains, it is not. A $0.001 transaction on Solana or $0.02 on Polygon makes micro-transactions economically viable. The landscape in 2026 is dramatically different from the $100-gas-fee environment of 2021.
“DeFi platforms hide fees.” Most DeFi platforms are more transparent about fees than traditional financial intermediaries. Uniswap shows you the exact fee tier of each liquidity pool before you swap. Aave displays its interest rate model publicly. The fees that surprise users are typically gas fees — blockchain network costs — not hidden protocol charges.
“You cannot predict crypto fees.” You can make reasonable predictions using current mempool data, historical patterns, and fee estimation tools. You cannot predict with certainty because network conditions change second by second, but the tools available make it entirely possible to make informed, cost-effective decisions rather than guessing.
9. The Future of Crypto Fee Models
Ethereum’s Roadmap and L2 Dominance
The Ethereum ecosystem’s fee trajectory is clearly downward for end users, driven by two simultaneous forces: continued Layer 2 adoption and protocol-level upgrades that reduce L2 costs further. EIP-4844 (blob transactions), implemented through the Dencun upgrade, reduced L2 data posting costs by 50–90%. The next phase — the Prague hard fork and longer-term sharding implementation — is expected to reduce L2 fees by another 10x to 100x as more data capacity becomes available.
With forecasts suggesting up to 80% of Ethereum-related transactions will occur on L2 by 2026 and beyond, the mainnet is increasingly functioning as a settlement and security layer rather than an execution environment. This is the intended architecture: high-value settlements where mainnet’s security is worth the cost, and everyday activity where L2’s near-zero fees make participation accessible.
AI-Assisted Fee Optimisation
Several wallet providers and third-party tools are developing AI-driven fee management that analyses network patterns, transaction type, and user timing preferences to suggest optimal submission windows. Rather than requiring users to understand gas markets themselves, these tools handle fee optimisation automatically — analogous to how a travel app finds the cheapest flight time rather than requiring users to check prices manually. The practical impact for most users will be lower fees without requiring any additional knowledge.
Bitcoin’s Long-Term Fee Economics
Bitcoin’s halving schedule means miner revenue from block subsidies will continue to decline in absolute terms over time. The long-term health of Bitcoin’s security depends on transaction fees becoming sufficient to maintain miner incentives as subsidies decrease. This is a genuine open question in Bitcoin’s economic design. The emergence of Ordinals and Bitcoin-native token protocols has added new fee demand that did not exist before 2023, which is a development worth watching as it evolves.
Cross-Chain Fee Optimisation
As multi-chain infrastructure matures, users will increasingly have tools that automatically route transactions through the cheapest chain that meets their requirements. Rather than manually deciding “should I do this on Ethereum mainnet, Arbitrum, or Polygon?”, future wallets and dApps will make that determination in the background and execute on the optimal network. The user experience will abstract away fee complexity while the underlying economics continue to improve.
10. Frequently Asked Questions About Crypto Fees
What are crypto fees and who receives them?
Crypto fees are payments made to miners or validators for processing and confirming blockchain transactions. On Bitcoin, fees go entirely to miners. On Ethereum post-EIP-1559, the base fee is burned (removed from circulation) and only the priority fee goes to validators.
Why do crypto fees fluctuate so much?
Fees fluctuate because block space is limited and demand is variable. When many users want to transact simultaneously, competition for block space drives fees up. When demand is low, fees fall. Gas prices on Ethereum can change by 10x within hours during major market events.
What is a gas fee and how is it different from a transaction fee?
“Gas fee” is the specific term used on Ethereum and EVM-compatible blockchains for the cost of computational operations. “Transaction fee” is the broader term used across blockchains including Bitcoin. All gas fees are transaction fees, but not all transaction fees are called gas fees.
How can I reduce my crypto transaction fees right now?
The most impactful steps are: move Ethereum activity to an L2 like Arbitrum or Optimism for 95–99% fee reduction, use SegWit addresses for Bitcoin, time non-urgent transactions for low-congestion periods, and use fee estimation tools to avoid overpaying. On L2s and alternative chains like Solana and Polygon, fees are already near-zero for most operations.
Are Layer 2 transaction fees secure?
Yes. The major Ethereum L2s — Arbitrum, Optimism, Base, zkSync — inherit Ethereum’s security through cryptographic proofs posted to the mainnet. Your funds are not less secure on an L2 than on mainnet, provided you use official bridges and verified contract addresses. The primary risk is using unofficial bridges or phishing sites, not the L2 technology itself.
What is the cheapest blockchain for transactions in 2026?
For pure value transfers, Nano and IOTA offer near-zero fees. For DeFi and smart contract interactions, Solana charges roughly $0.001 per swap, Polygon around $0.02, and Arbitrum around $0.03. For users who need Ethereum-compatible DeFi with minimal fees, the major Ethereum L2s offer the best combination of low cost and ecosystem depth.
Do crypto fees affect transaction speed?
Yes. Higher fees improve priority in the mempool and typically result in faster confirmation. On networks with dynamic fee markets like Ethereum, you can pay a higher priority fee to jump ahead of lower-fee transactions in the queue. On L2 networks where fees are already near-zero, this distinction barely matters because confirmations are fast regardless.
Can I get a refund if my transaction fails?
On Ethereum, gas is consumed even if a transaction fails — because the computational work was done even though the desired outcome was not achieved. You pay for the computation, not the result. This is a common and painful surprise for new users. Setting appropriate gas limits and using well-audited protocols reduces (but does not eliminate) the risk of failed transactions.
