default7702GasEstimator

A middleware function to estimate the gas usage of a user operation when using an EIP-7702 delegated account. Has an optional custom gas estimator. This function is only compatible with accounts using EntryPoint v0.7.0, and the account must have an implementation address defined in getImplementationAddress().

const default7702UserOpSigner: (userOpSigner?: ClientMiddlewareFn) => ClientMiddlewareFn
Provides a default middleware function for signing user operations with a client account when using EIP-7702 delegated accounts. If the signer doesn't support signAuthorization, then this just runs the provided signUserOperation middleware. This function is only compatible with accounts using EntryPoint v0.7.0, and the account must have an implementation address defined in getImplementationAddress().
