Anyswap vs Multichain: What the Name Change Means
Anyswap and Multichain are not two competing protocols: Anyswap was the earlier brand, and the project announced the Multichain name in December 2021. That answer holds only for the historical cross-chain project; a later website or token using “Anyswap” is not automatically connected to it. A reader checking the Anyswap interface should compare the domain, contract address, chain ID, token ticker, and quoted output before signing.
Treat Anyswap and Multichain as one historical lineage
The confusion comes from a genuine rebrand, not from two separate blockchains. Anyswap began as a cross-chain decentralized exchange, then shifted toward bridge infrastructure. Multichain later presented the same project as a Cross-Chain Router Protocol, or CRP.
That change also altered the language around the product. Older guides may describe an Anyswap bridge, Anyswap DEX, or ANY governance token. Later material may refer to the Multichain router and MULTI token. Those names describe different stages and components of one historical project. They do not prove that every current domain, contract, or token carrying the name is connected to it.
| Label shown | What it usually indicates | What it does not prove |
|---|---|---|
| Anyswap or AnySwap | Earlier project branding | That a current interface is official |
| Multichain | Later brand and router positioning | That an old route still operates |
| ANY | Earlier governance-token ticker | That it is the same contract as MULTI |
| MULTI | Replacement governance-token ticker | That a token list is authentic |
Before signing, check Anyswap-era identity
A ticker is not an identity. On EVM networks, the contract address and chain ID matter more than the symbol displayed by a wallet. An ERC-20 called ANY on Ethereum is not automatically the historical Anyswap token, and a token called MULTI is not automatically the migrated governance asset.
The historical ANY-to-MULTI process was a one-way 1:1 conversion on Ethereum, with ETH required for gas. That was a token migration, not an ordinary market swap and not a bridge transfer. Its old rules should never be treated as proof that a present-day conversion is available.
Let the route reveal what the interface is doing
A bridge generally moves the same asset representation between networks. A router can coordinate a bridge, a liquidity-pool exchange, a token conversion, or a destination-chain contract call. For example, USDC on Ethereum moving to a supported USDC representation on Polygon is different from USDC on Ethereum becoming USDT on Polygon.
That distinction affects the transaction. A bridge may use lock-and-mint or burn-and-mint mechanics. A liquidity route may add pool fees, spread, price impact, and slippage. Both can also involve source-chain gas and a relayer or destination-chain charge. Ethereum’s bridge documentation identifies lock-and-mint, burn-and-mint, and atomic swaps as common designs, while noting that bridge fees can depend on gas costs and route liquidity.
Keep the token migration separate from the token swap
- Confirm the source and destination chain IDs.
- Compare the full token contract addresses, not only the tickers.
- Read the output asset, recipient, minimum received amount, and fee breakdown.
- Inspect the wallet request for separate ERC-20 approval and router or bridge calls.
What decided it for me was the contract address, not the logo. A familiar name can appear in an interface, repository, or token list while the signed transaction points somewhere else. Anyswap and Multichain explain the history; the transaction details determine what the user is actually authorizing.
