relay_swap_multi_input
Execute multi-chain token swaps by specifying origins from multiple chains and a destination chain. Supports exact input (fixed source amounts) or exact output (fixed destination amount). Use token contract addresses for currencies.
Instructions
Execute multi-chain token swaps. IMPORTANT: For EXACT_INPUT, do NOT include "amount" at root level - only in origins array. For EXACT_OUTPUT, include "amount" at root level. Always use TOKEN CONTRACT ADDRESSES. Examples:
EXACT_INPUT (Bridge 1 USDC from Ethereum to Optimism): {"user": "0x123...", "origins": [{"chainId": 1, "currency": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", "amount": "1000000"}], "destinationChainId": 10, "destinationCurrency": "0x0b2c639c533813f4aa9d7837caf62653d097ff85", "tradeType": "EXACT_INPUT"}
EXACT_OUTPUT (Get exactly 100 USDC on Base): {"user": "0x123...", "amount": "100000000", "origins": [{"chainId": 1, "currency": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", "amount": "50000000"}], "destinationChainId": 8453, "destinationCurrency": "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913", "tradeType": "EXACT_OUTPUT"}
