Return authorization list for SetCodeTx type

[m-Peter]

Description

As described in the specification: https://eip7702.io/#specification, the new SetCodeTx type, has an authorization list:

authorization_list = [[chain_id, address, nonce, y_parity, r, s], ...]

Example:

{
    address: '0x313af46a48eeb56d200fae0edb741628255d379f',
    chainId: 646,
    nonce: 4,
    r: '0xf4bc19cca28390f3628cfcda9076a8744b77cc87fa4f7745efa83b7a06cc3514',
    s: '0x1d736fecc68ee92ab6fd805d91a3e3dbf27097d3578561402d7105eeeee00bb7',
    yParity: 0
}

We need to include this information in the result of eth_getTransactionByHash JSON-RPC endpoint.

Walkthrough

The changes introduce support for an AuthorizationList in Ethereum transaction structures and interfaces, updating both backend Go code and frontend JavaScript tests. The Go code adds a new field and method for handling code authorizations, while the JavaScript tests are enhanced to fetch and assert detailed transaction data, especially focusing on the new authorization list for EIP-7702 type transactions.

Changes

File(s)	Change Summary
eth/types/types.go	Added AuthorizationList []types.SetCodeAuthorization field to the Transaction struct and updated the NewTransaction function to populate this field for transaction types beyond blob transactions. Added detailed comments explaining incremental field application based on transaction type.
models/transaction.go	Extended the Transaction interface with a new method SetCodeAuthorizations() []gethTypes.SetCodeAuthorization. Implemented this method in the DirectCall struct, returning an empty slice.
tests/web3js/eth_eip_7702_contract_write_test.js tests/web3js/eth_eip_7702_sending_transactions_test.js	Updated tests to first fetch transactions using publicClient.getTransaction({ hash }), then assert on transaction fields including from, type, input, and detailed authorizationList contents (signature components, nonce, chainId, address). Afterwards, fetched and asserted on transaction receipts. This adds more granular validation of transaction data for EIP-7702 transactions.

Poem

In fields of code where rabbits run,
A list of authorizations has begun.
Transactions now with secrets tight,
Are checked in tests, both day and night.
With every hop, a field appears—
Secure and clear, the code now cheers!
🐇✨

Tip

⚡️ Faster reviews with caching

• CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.

Can you explain this check here? And maybe add https://eip7702.io/#specification to the comments for reference.

[m-Peter]

Good point, the checks can be a bit difficult to grasp. Added some helpful comments in 3ceea86 .

Thanks for the comments.
