Overview The ThorSwapFacet enables cross-chain token transfers using THORChain through the ThorSwap interface. THORChain provides decentralized cross-chain liquidity without wrapped tokens.
Contract Interface Bridging Functions startBridgeTokensViaThorSwap Bridges tokens to another chain using THORChain.
function startBridgeTokensViaThorSwap ( BridgeData _bridgeData , ThorSwapData _thorSwapData ) external payable
Standard bridge data containing transaction details
ThorSwap-specific bridging parameters THORChain memo for routing
Transaction expiration timestamp
swapAndStartBridgeTokensViaThorSwap Performs a token swap on the source chain before bridging via THORChain.
function swapAndStartBridgeTokensViaThorSwap ( BridgeData _bridgeData , SwapData [] _swapData , ThorSwapData _thorSwapData ) external payable
Array of swap operations to execute before bridging
ThorSwap-specific parameters
Data Structures ThorSwapData struct ThorSwapData { address vault ; // THORChain vault string memo ; // THORChain memo uint256 expiration ; // Expiration timestamp }
Usage Example import { ThorSwapFacet } from '@lifi/contract-types' ; const thorSwapFacet = ThorSwapFacet__factory . connect ( facetAddress , signer ); const bridgeData = { transactionId: '0x...' , bridge: 'thorswap' , integrator: 'my-dapp' , referrer: '0x0000000000000000000000000000000000000000' , sendingAssetId: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48' , // USDC receiver: '0x...' , minAmount: ethers . utils . parseUnits ( '100' , 6 ), destinationChainId: 1 , // Ethereum (or other chain) hasSourceSwaps: false , hasDestinationCall: false }; const thorSwapData = { vault: '0x...' , // THORChain vault memo: '=:ETH.ETH:0x...' , expiration: Math . floor ( Date . now () / 1000 ) + 3600 }; const tx = await thorSwapFacet . startBridgeTokensViaThorSwap ( bridgeData , thorSwapData , { value: 0 } ); await tx . wait ();
Events The facet emits standard LiFi events:
