What is EntryPoint?

An EntryPoint is a unique smart contract designed to process transactions received from Bundlers. It plays a critical role in verifying and executing UserOperations.

Verification Process: The EntryPoint first verifies whether the wallet possesses sufficient funds to cover the maximum potential gas usage, as indicated by the gas field in the UserOperation. If the wallet's funds are insufficient, the transaction is declined.

Execution Mechanism: Once verified, the EntryPoint executes the transaction. It then deducts the appropriate amount of native tokens from the Smart Contract Account (SCA) to compensate the Bundler for the gas used during the transaction process.
