Note

Medium Risk
Mostly adds test-only Solidity contracts and E2E coverage, but also updates the local Docker Besu package tag and contract predeploy/nonces, which can break local dev/e2e setups if mismatched.

Overview
Adds a new EIP-7702 local test fixture: three Solidity contracts (Eip7702TestNested, Eip77022Delegated, Eip7702TestEntrypoint) plus static artifacts and a deployEIP7702Contracts.ts script wired into deploy-contracts via makefile-contracts.mk.

Extends the E2E suite to validate nested delegation denylist enforcement (verifying a transaction is not mined when an intermediate delegated EOA is denylisted), and updates denylist reload behavior to refresh both TransactionPoolValidator and TransactionSelector plugins.

Updates local E2E config to include predeployed EIP-7702 contract addresses and adjusts existing local contract addresses/nonces; also bumps the local linea-besu-package image tag in compose-spec-l2-services.yml.

Delegation transaction uses wrong account's nonce

Medium Severity

nonceActor fetches the transaction count for actor.address, but is then used as the nonce for a transaction sent by relayerWalletClient. The EIP-7702 authorizationList transaction is submitted by the relayer, so the transaction nonce must be the relayer's nonce. This works by coincidence because both are freshly generated accounts with nonce 0, but it is logically incorrect and fragile. The second transaction later in the test correctly uses sequencerClient.getTransactionCount({ address: relayer.address }).
