Optimism Documentation

op-reth is the Rust execution client for the OP Stack, based on Reth. It implements the same Engine API and Ethereum JSON-RPC surface as op-geth, so it is a drop-in alternative on OP Stack chains. This page documents the JSON-RPC methods that were tested against an OP Stack devnet running op-reth v2.2.3 (build reth/v2.2.0-88505c7) with the V2 (Jovian) fee model active.

Overview

op-reth implements the standard Ethereum JSON-RPC API with the same OP Stack additions as op-geth. Familiar Ethereum tools (cast, web3.js, ethers, viem, …) work without modification.

The execution engine’s RPC interface is functionally identical to the upstream Reth RPC interface. The OP-specific behavior matches op-geth: transaction receipts include additional L1 data-availability fee fields, and deposit transactions (type 0x7e) carry OP-specific fields.

Key Differences from Ethereum

While op-reth maintains compatibility with Ethereum’s JSON-RPC API, there are important differences shared with the wider OP Stack:

Transaction Receipts

User transaction receipts include additional L1 data fee information. With the V2 (Jovian) fee model the fields are:

l1GasUsed — Amount of L1 gas attributed to L1 data availability.
l1GasPrice — L1 base fee at the time of execution.
l1Fee — Total L1 data fee charged in wei.
l1BaseFeeScalar — Scalar applied to the L1 base fee component.
l1BlobBaseFee — L1 blob base fee at the time of execution.
l1BlobBaseFeeScalar — Scalar applied to the L1 blob base fee component.
daFootprintGasScalar — Scalar applied to the data-availability footprint.

The legacy single-scalar field l1FeeScalar (used by Bedrock-era chains and still shown in older op-geth docs) is not present on V2 chains. Clients that hardcode l1FeeScalar need to read the new scalar fields above. The l1GasUsed, l1GasPrice, and l1Fee fields are unchanged.

Deposit transactions

OP Stack deposit transactions (type: 0x7e) include extra fields in both transaction and receipt responses:

On the transaction: sourceHash, mint, depositReceiptVersion.
On the receipt: depositNonce, depositReceiptVersion.

Gas Price Calculation

For L2 gas prices, use the standard eth_gasPrice method. For L1 gas prices and end-to-end fee estimation, use the GasPriceOracle predeploy or the Optimism SDK.

Standard JSON-RPC Methods

All examples below were verified live against op-reth v2.2.3.

eth_blockNumber

Returns the number of the most recent block.

curl
cast

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
  http://localhost:8545

cast block-number --rpc-url http://localhost:8545

Sample success output:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x1202c"
}

eth_chainId

Returns the currently configured chain ID, used for signing replay-protected transactions.

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \
  http://localhost:8545

Sample success output:

{ "jsonrpc": "2.0", "id": 1, "result": "0x190a85e3" }

eth_syncing

Returns sync status.

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' \
  http://localhost:8545

Unlike op-geth, op-reth always returns a structured object that lists each pipeline stage (Headers, Bodies, Execution, MerkleExecute, …) and their per-stage progress, even when the node is fully synced. Clients that treat any non-false response as “still syncing” need to compare currentBlock and highestBlock instead.

Sample output (synced node):

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "startingBlock": "0x1202c",
    "currentBlock": "0x1202c",
    "highestBlock": "0x1202c",
    "stages": [
      { "name": "Headers", "block": "0x1202c" },
      { "name": "Bodies", "block": "0x1202c" },
      { "name": "Execution", "block": "0x1202c" },
      { "name": "MerkleExecute", "block": "0x1202c" },
      { "name": "Finish", "block": "0x1202c" }
    ]
  }
}

eth_getBalance

Returns the balance of the account at the given address.

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_getBalance","params":["0x4200000000000000000000000000000000000015","latest"],"id":1}' \
  http://localhost:8545

Sample success output:

{ "jsonrpc": "2.0", "id": 1, "result": "0x0" }

eth_getTransactionByHash

Returns information about a transaction by transaction hash. Deposit transactions include sourceHash, mint, and depositReceiptVersion.

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_getTransactionByHash","params":["0x38a7db9aa2d7ec70d55ac7de90384279bdcad38ecdf68e3fcc4c6b649761daf9"],"id":1}' \
  http://localhost:8545

Sample success output (deposit transaction):

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "type": "0x7e",
    "sourceHash": "0xdbad163233eb082b43df51b26625dcfbd997bcd2f0810a58a651c633516c4941",
    "from": "0xdeaddeaddeaddeaddeaddeaddeaddeaddead0001",
    "to": "0x4200000000000000000000000000000000000015",

    "r": "0x0", "s": "0x0", "v": "0x0", "yParity": "0x0"
  }
}

eth_getTransactionReceipt

Returns the receipt of a transaction by hash. Includes OP Stack–specific L1 fee fields. The example below is a deposit-tx receipt (note the depositNonce / depositReceiptVersion fields and l1Fee = 0); a regular user-tx receipt will carry a non-zero l1Fee computed from the V2 scalars.

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_getTransactionReceipt","params":["0x38a7db9aa2d7ec70d55ac7de90384279bdcad38ecdf68e3fcc4c6b649761daf9"],"id":1}' \
  http://localhost:8545

Sample success output:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "type": "0x7e",
    "status": "0x1",
    "cumulativeGasUsed": "0xb44e",
    "logs": [],
    "logsBloom": "0x000…",
    "transactionHash": "0x38a7db9aa2d7ec70d55ac7de90384279bdcad38ecdf68e3fcc4c6b649761daf9",
    "transactionIndex": "0x0",
    "blockHash": "0x5bbabb299894fa2f763a0b6bbccc966b80e791aa49663b80fc9789e0f04183ea",
    "blockNumber": "0x1202c",
    "gasUsed": "0xb44e",
    "effectiveGasPrice": "0x0",
    "blobGasUsed": "0xabe0",
    "from": "0xdeaddeaddeaddeaddeaddeaddeaddeaddead0001",
    "to": "0x4200000000000000000000000000000000000015",
    "contractAddress": null,
    "depositNonce": "0x1202b",
    "depositReceiptVersion": "0x1",
    "l1GasPrice": "0x35",

    "l1BlobBaseFee": "0x3",
    "l1BlobBaseFeeScalar": "0xc3c9d",
    "daFootprintGasScalar": "0x190"
  }
}

Notice the OP-specific fields at the end of the receipt: l1GasUsed, l1GasPrice, l1Fee, plus the V2 scalars l1BaseFeeScalar, l1BlobBaseFee, l1BlobBaseFeeScalar, and daFootprintGasScalar. The Bedrock-era l1FeeScalar field is not present on V2 chains.

eth_call

Executes a new message call immediately without creating a transaction on the blockchain. Example calls GasPriceOracle.l1BaseFee().

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x420000000000000000000000000000000000000F","data":"0x519b4bd3"},"latest"],"id":1}' \
  http://localhost:8545

Sample success output:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x0000000000000000000000000000000000000000000000000000000000000030"
}

eth_estimateGas

Generates and returns an estimate of gas needed for a transaction to complete.

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_estimateGas","params":[{"from":"0x0000000000000000000000000000000000000001","to":"0x0000000000000000000000000000000000000002","value":"0x0"}],"id":1}' \
  http://localhost:8545

Sample success output:

{ "jsonrpc": "2.0", "id": 1, "result": "0x52e9" }

eth_estimateGas only estimates L2 execution gas. To calculate the total transaction cost including L1 data fees, use the Optimism SDK or query the GasPriceOracle predeployed contract.

eth_sendRawTransaction

Submits a signed transaction to the network. The example payload is intentionally invalid to demonstrate the error shape.

curl -X POST -H "Content-Type: application/json" --data \
  '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"],"id":1}' \
  http://localhost:8545

Sample error output:

{
  "jsonrpc": "2.0",
  "id": 1,
  "error": { "code": -32602, "message": "failed to decode signed transaction" }
}

A well-formed signed transaction returns the transaction hash as result.

eth_getBlockByNumber

WebSocket Support

op-reth supports WebSocket connections for real-time event subscriptions using the eth_subscribe method. Default port is 8546.

eth_subscribe

Creates a subscription for specific events. Verified subscription topics include newHeads, logs, newPendingTransactions, and syncing.

// Connect to WebSocket
const ws = new WebSocket('ws://localhost:8546');

// Subscribe to new block headers
ws.send(JSON.stringify({
  "jsonrpc": "2.0",
  "method": "eth_subscribe",
  "params": ["newHeads"],
  "id": 1
}));

// Subscribe to logs
ws.send(JSON.stringify({
  "jsonrpc": "2.0",
  "method": "eth_subscribe",
  "params": [
    "logs",
    {
      "address": "0x8320fe7702b96808f7bbc0d4a888ed1468216cfd",
      "topics": ["0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef"]
    }
  ],
  "id": 2
}));

Subscription acknowledgement:

{ "jsonrpc": "2.0", "id": 1, "result": "0x8045a58dd94ddef0a9b0ac15ab397550" }

Event notification (newHeads):

{
  "jsonrpc": "2.0",

eth_unsubscribe

Cancels an active subscription.

ws.send(JSON.stringify({
  "jsonrpc": "2.0",
  "method": "eth_unsubscribe",
  "params": ["0x8045a58dd94ddef0a9b0ac15ab397550"],

}));

Methods that behave differently from op-geth

These calls are worth flagging for tooling that auto-detects client capability:

Method	op-geth	op-reth
`rpc_modules`	Returns the namespace → version map.	Not implemented — returns `-32601 Method not found`. Use `web3_clientVersion` to identify the client.
`eth_syncing`	Returns `false` when synced.	Always returns a structured object with per-stage progress; compare `currentBlock` and `highestBlock` to determine “synced”.
`trace_*` (Parity) namespace	Not exposed; `op-geth` uses `debug_*`.	Available in `op-reth`, but only when `trace` is added to `--http.api`. Not enabled by default in our compose file.
Receipt L1 fee scalars	Single legacy `l1FeeScalar` field on pre-Ecotone receipts.	V2 (Jovian) fields: `l1BaseFeeScalar`, `l1BlobBaseFee`, `l1BlobBaseFeeScalar`, `daFootprintGasScalar`; `l1FeeScalar` removed. (Same on `op-geth` once V2 is active.)

Running a Node with RPC Access

To run your own op-reth node with full RPC access:

op-reth node \
  --chain /config/genesis.json \
  --datadir /data \
  --http \
  --http.addr 0.0.0.0 \
  --http.port 8545 \
  --http.api eth,net,web3,debug,txpool,trace \
  --ws \
  --ws.addr 0.0.0.0 \
  --ws.port 8546 \
  --ws.api eth,net,web3 \
  --authrpc.addr 0.0.0.0 \
  --authrpc.port 9551 \
  --authrpc.jwtsecret /config/jwt.hex \
  --rollup.sequencer-http https://<sequencer-rpc> \
  --rollup.disable-tx-pool-gossip

Be cautious when exposing RPC endpoints publicly. Use authentication, rate limiting, and firewall rules to prevent abuse. The debug and trace namespaces should only be enabled for trusted clients.

Test environment

The samples above were generated by running each curl/websocat command against an op-reth v2.2.3 (reth/v2.2.0-88505c7) node in our u19-beta-v223 devnet (chain ID 0x190a85e3 / 420120035), HTTP port 8555, WS port 8556. All listed methods returned successful (or expected-error) responses.
