Note

Refactors EthApi into modular interfaces with many new eth_* methods, implements them in Web3j clients (with retries), adds domain models/mappers, and updates coordinator and log searcher to new APIs.

• API Surface (major refactor):
  • Split EthApiClient into modular interfaces: EthApiChainIdClient, EthApiFeeClient, EthApiSimulationClient, EthApiBlockClient, EthLogsClient, EthApiAccountClient, EthApiTransactionClient, EthApiExecutionClientInfo.
  • Add methods: ethChainId, ethBlockNumber, block getters (ethFind/GetBlockByNumber{FullTxs,TxHashes}), account (ethGetBalance, ethGetTransactionCount), fees (ethGasPrice, ethMaxPriorityFeePerGas, ethFeeHistory), txs (ethGetTransactionByHash, ethGetTransactionReceipt, ethSendRawTransaction), node info (ethProtocolVersion, ethCoinbase, ethMining), simulation (ethCall, ethEstimateGas).
• Domain Models & Mappers:
  • New TransactionForEthCall and TransactionReceipt models; add mappers (TransactionForEthCallMapper, TransactionReceiptMapper).
• Client Implementations:
  • Web3jEthApiClient implements new methods; Web3jEthApiClientWithRetries wraps them with tailored retry predicates (incl. execution-reverted stop).
  • EthLogsClient adds FilterOptions + ethGetLogs helper.
  • FakeEthApiClient updated to new interface/methods.
• Call Sites Updated:
  • Replace getChainId() with ethChainId() and getBlockByNumberWithoutTransactionsData() with ethGetBlockByNumberTxHashes() in coordinator components and log searcher.
• Tests:
  • Update tests to use new method names (ethGetBlockByNumber{FullTxs,TxHashes}) and behaviors.
