Transactions

Generates ready-to-sign transaction calldata for any supported vault action. Pass the output directly to your wallet provider — no ABI encoding required.

Typical flow

Check what the user can do Call GET /v2/transactions/context/{userAddress}/{network}/{vaultId} to fetch the user’s balances, limits, supported actions, required steps, and rewards context for that vault.
Build the transaction payload Call GET /v2/transactions/{action}/{userAddress}/{network}/{vaultId} with the action you want to prepare. Include assetAddress and either amount for a specific amount or all=true for a full redeem-style action.
Send the returned transaction with the user’s wallet The response includes the target address, calldata, and value. You do not need to encode the vault contract call yourself.

curl "https://api.vaults.fyi/v2/transactions/deposit/0xUSER/base/0xVAULT?assetAddress=0xASSET&amount=1000000" \

Capability	How to call	Required inputs
Check available vault actions	`GET /v2/transactions/context/{userAddress}/{network}/{vaultId}`	Path: `userAddress`, `network`, `vaultId`
Build deposit, redeem, request, or claim calldata	`GET /v2/transactions/{action}/{userAddress}/{network}/{vaultId}`	Path: `action`, `userAddress`, `network`, `vaultId`. Query: `assetAddress`, plus `amount` or `all=true` when the action requires an amount
Check claimable rewards	`GET /v2/transactions/rewards/context/{userAddress}`	Path: `userAddress`
Build rewards claim calldata	`GET /v2/transactions/rewards/claim/{userAddress}`	Path: `userAddress`. Query: `claimIds`
Add transaction attribution	`GET /v2/transactions/suffix/{userAddress}/{vaultId}`	Path: `userAddress`, `vaultId`

Alpha and Beta transaction endpoints extend the same wallet-action pattern to newer surfaces. Use them when your product needs these flows before they are promoted to stable V2.
