Set your transfer parameters
Before you can send tokens or messages, you'll need to set your parameters.
Now you're ready to set the parameters of your trade request.

Due to low liquidity on testnet, we ask that you limit your trade size in most cases to less than 0.1 of the native gas token (e.g. <0.1 ETH, or AVAX).
Note that the same token types (i.e. USDC) often has a different address on each chain. Make sure you've checked the address is right for the chain you are sending from/to.
Params are structured as aMapChainIdName object. A
GetRoute object describes a desired any-to-any transfer. It is defined by the following interface:Property | Description |
|---|---|
fromChain | |
fromToken | |
fromAmount | Amount of tokens to be sent (in EVM wei or "u" Cosmos micro units) |
toChain | |
toToken | |
fromAddress | Fallback address for the EVM or Cosmos part of the trade. Must be set when executing swaps from EVM to/from Cosmos |
toAddress | The recipient address to receive the tokens |
slippage | Max slippage across route, (0.3-99.99) 1 = 1% slippage. |
quoteOnly (optional) | If true, returns only a quote for the route. Omits transaction data needed for execution. Defaults to false |
prefer (optional) | When set, the route response will prefer routes from the DEX corresponding to the string. See possible strings here.
EVM chains only supported. |
collectFees | Integrators can pass in a wallet address and a fee percentage - see fees section |
If you want to send or receive native tokens (i.e ETH), the
sourceTokenAddress or destinationTokenAddress arguments must be set to 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeELast modified 1mo ago
