Get supported tokens for swap operations GET

Returns a list of all supported tokens that support crosschain swaps on Across Protocol.

Track the lifecycle of a deposit GET

Returns the fill status of a deposit along with a corresponding fill transaction hash if filled. This endpoint loads data queried by an indexing service that polls relevant events on a 10-second cadence. Users should therefore expect an average latency of 1 to 15 seconds after submitting a deposit to see the status changed in this endpoint. This delay comes from the time it takes for the internal indexing to include the deposit transaction.
