Submit a signed UserOperation¶

POST /api/aa/submit-userop

Wraps the signed UserOperation in EntryPoint.handleOps and relays it (Edith is a bundler-of-one) through the normal transaction pipeline. The account owner is recovered from the op signature and metered — so the owner directly, or a service acting for them, may submit; the owner is charged the bundle's real gas cost. The owner must be a registered Edith user. Returns a txId that tracks like any relay.

Authentication

Send your API key in the api-key header.
