…rinsic - Add EIP-7702 authorization list processing to dry_run_eth_transact - Split eth_call into eth_call (9 args) and eth_call_with_authorization_list (10 args) - Update call.rs to dispatch to correct extrinsic based on authorization list - Add eth_call_with_authorization_list to SetWeightLimit implementation - Add builder function for eth_call_with_authorization_list in tests - Refactor eip7702.rs to use WeightMeter for progressive weight charging

- Move TransactionMeter creation inside with_ethereum_context closure - Handle meter creation errors by returning EthereumCallResult with error - Process authorizations inside closure with proper error handling - Fixes OutOfGas errors in test_runtime_set_authorization and related tests Note: Tests now fail at delegation assertion instead of OutOfGas, indicating authorization processing may need to happen outside transaction scope.
- Change Call variant to eth_call_with_authorization_list with named field - Move authorization processing outside with_ethereum_context closure - Use TransactionMeter with WeightAndDeposit limits for auth processing - Subtract consumed gas from eth_gas_limit for main call - Fixes delegation not being applied in runtime tests All three runtime tests now pass: - test_runtime_set_authorization - test_runtime_clear_authorization - test_runtime_delegation_resolution

Summary
This PR implements EIP-7702 for
pallet-revive, enabling Externally Owned Accounts (EOAs) to temporarily delegate their code execution to contract addresses via authorization tuples in transactions.Key Structural Changes
New
AccountType::DelegatedVariantThis allows EOAs to:
New
code_addressField in Execution Frame (exec.rs)Added
code_address: H160to theFramestruct to track where code/immutable data originates from:This unifies immutable data resolution across all execution modes.
EIP-7702 Authorization Processing Module (
evm/eip7702.rs)New module implementing the core EIP-7702 logic:
process_authorizations(): Processes authorization list with weight meteringvalidate_authorization(): Validates chain_id, recovers signer, checks nonce, verifies non-contract statusapply_delegation(): Sets/clears delegation indicator and increments nonceAuthorization List Support in
eth_callExtrinsic (lib.rs)Extended
eth_callwith anauthorization_listparameter:Delegation-Aware Code Resolution (
lib.rs)Updated
Pallet::code()to return the EIP-7702 delegation indicator (0xef0100 || target) for delegated accounts, enabling external tools to detect delegated EOAs.
