Optimism bundler methods

Infura integrates with the Pimlico account abstraction bundler infrastructure, enabling developers to access ERC-4337 smart account features.

The following bundler methods are supported on Optimism mainnet and Sepolia:

• eth_sendUserOperation: Submits a user operation to be included onchain.
• eth_estimateUserOperationGas: Simulates the user operation and estimates the appropriate gas limits.
• eth_getUserOperationReceipt: Fetches the receipt of a user operation.
• eth_getUserOperationByHash: Fetches the user operation by hash.
• eth_supportedEntryPoints: Fetches the EntryPoint addresses supported by the bundler.
• pimlico_getUserOperationGasPrice: Returns the gas prices that must be used for the user operation.
• pimlico_getUserOperationStatus: Returns the user operation status.
• pimlico_simulateAssetChanges: Simulates a user operation to predict the asset changes it will cause.
