Post /v2/fungible/msgs
This supports cross-chain actions among EVM chains, Cosmos chains, and between them. Returns minimal number of messages required to execute a multi-chain swap or transfer. Input consists of the output of route with additional information required for message construction (e.g. destination addresses for each chain)

Array of receipient and/or sender address for each chain in the path, corresponding to the chain_ids array returned from a route request
Amount of source asset to be transferred or swapped
Amount of destination asset out
Map of chain-ids to arrays of affiliates. The API expects all chains to have the same cumulative affiliate fee bps for each chain specified. If any of the provided affiliate arrays does not have the same cumulative fee, the API will return an error.

URI pointing to an image of the logo of the asset
Name of the asset
Chain-id of the origin of the asset. If this is an ibc denom, this is the chain-id of the asset that the ibc token represents
Denom of the origin of the asset. If this is an ibc denom, this is the original denom that the ibc token represents
Recommended symbol of the asset used to differentiate between bridged assets with the same symbol, e.g. USDC.axl for Axelar USDC and USDC.grv for Gravity USDC
Symbol of the asset, e.g. ATOM for uatom
Address of the contract for the asset, e.g. if it is a CW20 or ERC20 token
The forward slash delimited sequence of ibc ports and channels that can be traversed to unwind an ibc token to its origin asset.
Chain-id on which the transfer is initiated
Whether pfm is enabled on the chain where the transfer is initiated

Indicates whether this transfer is relayed via Smart Relay
Whether the transfer chain supports a memo
Chain-id on which the transfer is received
Amount of the fee asset to be paid as the transfer fee if applicable, converted to USD value
Index of the tx returned from Msgs that executes this operation
Percent tolerance for slippage on swap, if a swap is performed
Chain-id of the source asset
Denom of the source asset
Number of seconds for the IBC transfer timeout, defaults to 5 minutes
Response
Indicates fees incurred in the execution of the transfer
Amount of the fee asset to be paid
