Discover gVault yield sources

Call the gVault-specific catalogue before configuring either a direct integration or a fee wrapper. Every row returned by this endpoint is a gVault.

The response is an unpaginated integration manifest.

Persist the integration fields

Store these values per environment:

Field	Use
`id`	`gVaultId` in access and fee-wrapper API calls
`chain`	Network selection and transaction validation
`contractAddress`	Direct onchain contract address
`interface`	Contract-interface and operation-flow selection
`asset`	Deposit-token symbol, contract address, and decimals

Always verify asset() onchain against the manifest before requesting an ERC-20 approval.

Select by capability

Use the interface field to choose the ABI described in gVault contract interfaces. An USTB-style source can expose synchronous deposits and withdrawals plus queued redemptions. A Centrifuge-style source exposes request/claim lifecycles and may require the configured Ground router for deposits. Never copy IDs or addresses between sandbox and production. Fetch and validate the catalogue after changing API base URL or chain configuration. See the complete schema in List gVault yield sources.
