Bundlers
How bundlers submit validated UserOperations to the configured EntryPoint in DALP account abstraction flows.
A bundler is the account abstraction service that accepts, simulates, and submits valid UserOperations to the configured EntryPoint. In DALP, the public bundler-compatible JSON-RPC endpoint is a discovery surface for the active chain and supported EntryPoint, not a general UserOperation submission API.
What the bundler layer does
The bundler layer answers two operational questions:
| Question | DALP behaviour |
|---|---|
| Which chain is active? | Integrations can read the active chain ID from the bundler-compatible JSON-RPC endpoint. |
| Which EntryPoint is supported? | Integrations can read the EntryPoint address DALP resolves for the active network. |
DALP still applies platform checks before submission and still expects integrations to track the final transaction outcome after the operation reaches the chain.
What to use in integrations
Use Bundler JSON-RPC when a wallet, SDK, or integration needs the active chain ID or supported EntryPoint before building an account abstraction flow.
Use the REST smart wallet and paymaster endpoints for wallet state, signer management, approvals, gas readiness, funding, and sponsorship settings.
