}Swap tokens
Swap one token for another inside an Earn Account.
Exchanges tokens the Earn Account already holds in a single atomic transaction, so funds never leave it, and can be chained with other actions through the bundle endpoint (for example, swap ETH to USDC and deposit the USDC into a vault at once). Returns an unsigned transaction to sign and the expected output amount.
