11155111. Query GET /v2/microvaults/yield-sources?chainId=11155111 before configuring a strategy.
Each result includes the source ID used in strategy requests, the underlying contract addresses, provider and display names, current APY when available, supported synchronous or asynchronous operations, and expected processing time.
Availability in this endpoint means the source can be attached to a new MicroVault on that chain. A vault’s source mode can further restrict entry or exit without changing the global catalogue. Use processing-time fields to set expectations for asynchronous redemption; they are estimates rather than deadlines.
For source entry and exit controls, see Configure strategy and source modes.
