+BasePaymaster
+
+An ERC-4337 Paymaster contract by Pimlico which is able to sponsor gas fees in exchange for ERC20 tokens.
+The contract refunds excess tokens if the actual gas cost is lower than the initially provided amount.
+It also allows updating price configuration and withdrawing tokens by the contract owner.
+The contract uses an Oracle to fetch the latest token prices.
