/preview

post

https://foresight.noves.fi/evm/{chain}/preview

Takes an unsigned transaction object and returns a fully classified transaction, including an enriched English description of the action that is about to take place, and all relevant asset transfers tagged.

Optionally, it takes a stateOverrides object, which allows you to customize the state of the chain before the transaction is previewed. Useful for more advanced applications. You can skip this object to preview the transaction in the "real" state of the chain.
