impl EthApi

pub async fn erigon_get_header_by_number( &self, number: BlockNumber, ) -> Result<Option<AnyRpcBlock>, BlockchainError>

Otterscan currently requires this endpoint, even though it’s not part of the ots_*. Ref: https://github.com/otterscan/otterscan/blob/071d8c55202badf01804f6f8d53ef9311d4a9e47/src/useProvider.ts#L71

As a faster alternative to eth_getBlockByNumber (by excluding uncle block information), which is not relevant in the context of an anvil node

pub async fn ots_get_api_level(&self) -> Result<u64, BlockchainError>

As per the latest Otterscan source code, at least version 8 is needed. Ref: https://github.com/otterscan/otterscan/blob/071d8c55202badf01804f6f8d53ef9311d4a9e47/src/params.ts#L1C2-L1C2

pub async fn ots_get_internal_operations( &self, hash: B256, ) -> Result<Vec<InternalOperation>, BlockchainError>

Trace internal ETH transfers, contracts creation (CREATE/CREATE2) and self-destructs for a certain transaction.

pub async fn ots_has_code( &self, address: Address, block_number: BlockNumber, ) -> Result<bool, BlockchainError>

Check if an ETH address contains code at a certain block number.

pub async fn ots_trace_transaction( &self, hash: B256, ) -> Result<Vec<TraceEntry>, BlockchainError>

Trace a transaction and generate a trace call tree.

pub async fn ots_get_transaction_error( &self, hash: B256, ) -> Result<Bytes, BlockchainError>

Given a transaction hash, returns its raw revert reason.

pub async fn ots_get_block_details( &self, number: BlockNumber, ) -> Result<BlockDetails<AnyRpcHeader>, BlockchainError>

For simplicity purposes, we return the entire block instead of emptying the values that Otterscan doesn’t want. This is the original purpose of the endpoint (to save bandwidth), but it doesn’t seem necessary in the context of an anvil node

pub async fn ots_get_block_details_by_hash( &self, hash: B256, ) -> Result<BlockDetails<AnyRpcHeader>, BlockchainError>

For simplicity purposes, we return the entire block instead of emptying the values that Otterscan doesn’t want. This is the original purpose of the endpoint (to save bandwidth), but it doesn’t seem necessary in the context of an anvil node

pub async fn ots_get_block_transactions( &self, number: u64, page: usize, page_size: usize, ) -> Result<OtsBlockTransactions<AnyRpcTransaction, AnyRpcHeader>, BlockchainError>

Gets paginated transaction data for a certain block. Return data is similar to eth_getBlockBy* + eth_getTransactionReceipt.

pub async fn ots_search_transactions_before( &self, address: Address, block_number: u64, page_size: usize, ) -> Result<TransactionsWithReceipts<Transaction<AnyTxEnvelope>>, BlockchainError>

Address history navigation. searches backwards from certain point in time.

pub async fn ots_search_transactions_after( &self, address: Address, block_number: u64, page_size: usize, ) -> Result<TransactionsWithReceipts<Transaction<AnyTxEnvelope>>, BlockchainError>

Address history navigation. searches forward from certain point in time.

pub async fn ots_get_transaction_by_sender_and_nonce( &self, address: Address, nonce: U256, ) -> Result<Option<B256>, BlockchainError>

Given a sender address and a nonce, returns the tx hash or null if not found. It returns only the tx hash on success, you can use the standard eth_getTransactionByHash after that to get the full transaction data.

pub async fn ots_get_contract_creator( &self, addr: Address, ) -> Result<Option<ContractCreator>, BlockchainError>

Given an ETH contract address, returns the tx hash and the direct address who created the contract.

pub async fn build_ots_block_details( &self, block: AnyRpcBlock, ) -> Result<BlockDetails<Header<AnyHeader>>, BlockchainError>

The response for ots_getBlockDetails includes an issuance object that requires computing the total gas spent in a given block.

The only way to do this with the existing API is to explicitly fetch all receipts, to get their gas_used. This would be extremely inefficient in a real blockchain RPC, but we can get away with that in this context.

The original spec also mentions we can hardcode transactions and logsBloom to an empty array to save bandwidth, because fields weren’t intended to be used in the Otterscan UI at this point.

This has two problems though:

It makes the endpoint too specific to Otterscan’s implementation
It breaks the abstraction built in OtsBlock<TX> which computes transaction_count based on the existing list.

Therefore we keep it simple by keeping the data in the response

pub async fn build_ots_block_tx( &self, block: AnyRpcBlock, page: usize, page_size: usize, ) -> Result<OtsBlockTransactions<AnyRpcTransaction, AnyRpcHeader>, BlockchainError>

Fetches all receipts for the blocks’s transactions, as required by the ots_getBlockTransactions endpoint spec, and returns the final response object.

pub async fn build_ots_search_transactions( &self, hashes: Vec<B256>, first_page: bool, last_page: bool, ) -> Result<TransactionsWithReceipts<Transaction<AnyTxEnvelope>>, BlockchainError>
