Actions API
The Actions API (paths under /v1/actions/…) is the write-path counterpart: it computes quotes and builds the on-chain transactions a client needs to interact with a vault. Given a vault slug, asset, amount, and chain, an Actions API call returns either a quote (post-fee receive amount, fee breakdown, and a preview of the steps the user will sign) or a transaction bundle ready to broadcast — covering mint/deposit, redeem requests, instant redemptions, redemption updates, claims, and auto-claim operator approvals. The Actions API never holds private keys; the returned transactions are signed and submitted by the client’s own wallet. Use the Nest API to render vault state, and the Actions API the moment a user is ready to act on it.
The Actions API is currently only for EVM transactions. For SVM transactions, refer to the Solana Transaction Builder.
