MetaMask Swaps is an aggregation interface in the wallet extension and mobile app. It collects quotes from independent liquidity sources; MetaMask’s guide says it does not supply that liquidity or execute the trade as counterparty. Same-chain swaps and cross-chain routes therefore have different providers, fees and completion dependencies.[2]
Swap route and transaction stages
Sections ↑Reference table01
Route types
| Item | Published treatment | Practical scope |
|---|---|---|
| Same-chain swap | Input and output on one network | Liquidity source executes the token exchange |
| Cross-chain swap | Networks differ | Bridge or cross-chain provider participates |
| Direct external DEX | User opens a separate service | Different support and fee terms from the MetaMask Swap button |
Reference table02
Quote preparation
| Item | Published treatment | Practical scope |
|---|---|---|
| Source asset | Choose token and source network | Correct token representation matters |
| Destination | Choose token and destination network | Bridge support is route-specific |
| Simulation | MetaMask tests candidate transactions | A passing simulation does not guarantee eventual execution |
| Confirmation | Review quote before authorising | The blockchain transaction is a separate step |
Service charge, price impact and gas
Sections ↑Reference table03
Quoted cost components
| Item | Published treatment | Practical scope |
|---|---|---|
| MetaMask fee | 0.875% | Platform fee component |
| Quote rate | Token exchange rate | Depends on route and liquidity |
| Network fee | Gas | Separate blockchain cost |
| Bridge route | Provider-dependent costs | Compare the final output, not just the service percentage |
Reference table04
Fee-only arithmetic
| Item | Published treatment | Practical scope |
|---|---|---|
| US$100 equivalent | US$0.875 | At 0.875% |
| US$1,000 equivalent | US$8.75 | At 0.875% |
| US$10,000 equivalent | US$87.50 | At 0.875% |
Reference table05
Price impact and slippage
| Item | Published treatment | Practical scope |
|---|---|---|
| Price impact | Effect of trade size and available liquidity | Can already be reflected in the quote |
| Slippage tolerance | Permitted movement while transaction is pending | A wider limit accepts a worse possible outcome |
| No acceptable execution | Transaction may fail | Failure can still consume gas |
Reference table06
Failed-swap cost and retry behaviour
| Item | Published treatment | Practical scope |
|---|---|---|
| Price moves beyond tolerance | Swap can fail | Protects against execution outside the chosen bounds |
| Increase tolerance | May permit a later attempt | Also expands the adverse price movement accepted |
| Failed on-chain execution | Some gas can be spent | Paid to validators, not refunded as unused service |
| Persistent failure | Support can investigate DEX and asset route | Do not assume every failure is solved by higher slippage |
Gasless swaps and network requirements
Sections ↑Reference table07
How gasless differs from free gas
| Item | Published treatment | Practical scope |
|---|---|---|
| Payment asset | Part of the input token covers gas | No need for native-token balance on an eligible route |
| Quote | Gas cost is included | The economic charge still exists |
| Insufficient swap value | Cannot cover a larger gas bill | Gasless does not fund a deficit |
| Already enough native gas | Gasless option is not offered under the help rule | Normal native-token payment applies |
Reference table08
Current gasless prerequisites
| Item | Published treatment | Practical scope |
|---|---|---|
| Extension | Version 13.4 or newer | Current dedicated help article |
| Mobile | Version 7.62 or newer | Current dedicated help article |
| Smart Transactions | Enabled | Required setting |
| Estimate balance changes | Enabled | Required setting |
Reference table09
Gasless network scope
| Item | Published treatment | Practical scope |
|---|---|---|
| Same-chain | Ethereum, BNB Chain, Linea, Base, Arbitrum, Polygon, Robinhood | Availability still depends on token liquidity |
| Cross-chain origin | Ethereum, Linea, BNB Chain, Base, Arbitrum, Polygon | Destination support does not create origin eligibility |
| Base / Arbitrum / Polygon / Robinhood | Smart account required | Help says the account is automatically upgraded for this use |
| Solana | Different gas-sponsorship feature | Not the gasless mechanism described here |
Wallet control and protocol exposure
Sections ↑The wallet and the selected protocol have different roles. A self-custody wallet lets the user authorise transactions, but a swap can still interact with third-party contracts and bridges. Token allowances, route contracts and the destination network remain part of the transaction even when the interface presents one confirmation flow.[1][2]
Token availability is not universal support
Sections ↑Reference table10
Why a token may not have a swap route
| Item | Published treatment | Practical scope |
|---|---|---|
| Underlying liquidity | Required on supported decentralised sources | A wallet-visible balance need not be tradable |
| Approval / compatibility | Some tokens are excluded or do not work with Swaps | Importing the token does not override this |
| Current route | Can change with liquidity | A previous successful trade is not a future quote guarantee |
Transaction status and historical value
Sections ↑Reference table11
Reading a completed transaction
| Item | Published treatment | Practical scope |
|---|---|---|
| Transaction hash | Identifies the on-chain result | Use the correct network explorer |
| Current fiat estimate | Value at today’s price | Not necessarily acquisition value |
| Transfer-day estimate | Explorer’s historical value display | Useful context, not an invoice replacing the quote |
| Transferred token balance | Actual recorded quantity | Reconcile this with the wallet display |
Reference table12
Who supports the transaction
| Item | Published treatment | Practical scope |
|---|---|---|
| MetaMask Swap button | MetaMask Swaps support | Provide hash, network, tokens and route |
| Direct DEX transaction | The external platform or protocol | MetaMask help may only provide general orientation |
| Delayed bridge | Quoted completion time is an estimate | Check route status before treating delay as permanent failure |
Software operator and third-party agreements
Sections ↑The terms identify Consensys Software Inc., doing business as MetaMask. This software relationship is separate from the contract or protocol supplying a swap, bridge, fiat purchase or other financial function. An interface listing does not represent a universal financial-services permission for every token or country.[1]
Scope of this profile
Sections ↑This profile covers the Swap feature and the operational material linked from its help guide. Perpetuals, tokenized securities, cards and other separately marketed functions have additional eligibility and product rules; they are not represented as ordinary spot-swap permissions here.[2][1]
- Operator
- Consensys Software Inc., doing business as MetaMask; third-party venues and bridges execute the quoted swaps
- Exchange model
- Hybrid
- Service scope
- MetaMask aggregates third-party swap and bridge quotes. Its 0.875% service fee is only one cost component; gasless support, token liquidity and transaction settings determine whether a route can complete.
- Client types
- Retail clients
- Pricing publication
- Public pricing
- Other names
- MetaMask wallet swap aggregator
- Pricing scope
- 0.875% MetaMask fee plus quoted exchange rate and network/route costs. Gasless swaps pay gas from input assets; they are not universally free.
- Funding scope
- User-funded on-chain assets, gas payment and connected wallet balances; cross-chain transfers use independent bridges and may incur multiple chain costs.
- Custody and asset handling
- Self-custody wallet and user-authorised third-party protocol transactions; swaps and bridges retain smart-contract and route exposure.
- Client eligibility
- Wallet software and trade access depend on networks, tokens, sanctions and any third-party venue restrictions; app reachability is not a licence or universal fiat on-ramp.
- Support
- MetaMask support for Swap-button transactions; external DEX support for direct swaps elsewhere. Retain hash, network and route.
- Authorisation and registration scope
- Wallet software does not itself establish an authorised custodial exchange or protected deposit for every supported country; underlying DEX and bridge protocols are separately governed.
