Ink RPC and API Documentation
Complete guide to Ink RPC and API integration with Dwellir. Build DeFi applications on Kraken's OP Stack Ethereum L2 with fast, EVM-compatible infrastructure.
Ink RPC
With Dwellir, you get access to our global Ink network which always routes your API requests to the nearest available location, ensuring low latency and the fastest speeds.

Ink is an Ethereum Layer 2 built on the OP Stack and designed as a DeFi-focused home in the Optimism Superchain. It uses ETH for gas, supports standard EVM tooling, and gives Solidity developers a familiar path to deploy low-fee applications with fast confirmations.
DeFi-First L2
- Built for DeFi - Designed for liquidity, trading, and onchain financial applications
- Kraken-backed ecosystem - Launched by Kraken with builder support and DeFi distribution in mind
- Superchain alignment - Built on the OP Stack for Optimism ecosystem interoperability
EVM-Compatible Infrastructure
- Standard JSON-RPC - Use Ethereum RPC methods with existing tools and SDKs
- Solidity support - Deploy contracts built for Ethereum and other EVM L2s
- ETH gas - Keep familiar wallet and fee flows for users
Fast, Low-Fee Execution
- Chain ID 57073 - Ink mainnet
- Fast blocks - 1 second block times at launch
- Lower fees - OP Stack scaling with Ethereum settlement

API Methods
Core Ethereum Methods
Ink supports standard Ethereum JSON-RPC methods:
- Transaction methods (
eth_sendRawTransaction,eth_getTransactionReceipt) - Block methods (
eth_getBlockByNumber,eth_blockNumber) - Account methods (
eth_getBalance,eth_getCode) - Event methods (
eth_getLogs,eth_newFilter)
Debug & Trace Methods
Dwellir's Ink endpoint exposes reth-backed debug and trace namespaces:
debug_traceTransaction- Inspect transaction executiondebug_traceBlockByNumber- Trace full blockstrace_callandtrace_filter- Parity-style tracing workflows
Developer Resources
Ethers.js Example
import { ethers } from 'ethers';
const provider = new ethers.JsonRpcProvider(
'https://api-ink-mainnet.n.dwellir.com/YOUR_API_KEY'
);
const network = await provider.getNetwork();
console.log('Connected to Ink:', network.chainId === 57073n);
const blockNumber = await provider.getBlockNumber();
console.log('Latest Ink block:', blockNumber);viem Example
import { createPublicClient, http } from 'viem';
import { defineChain } from 'viem';
const ink = defineChain({
id: 57073,
name: 'Ink',
nativeCurrency: { name: 'Ether', symbol: 'ETH', decimals: 18 },
rpcUrls: {
default: {
http: ['https://api-ink-mainnet.n.dwellir.com/YOUR_API_KEY'],
},
},
});
const client = createPublicClient({
chain: ink,
transport: http(),
});
const blockNumber = await client.getBlockNumber();Resources & Support

eth_coinbase
Check the legacy eth_coinbase compatibility method on Immutable. Public endpoints may return an address, `unimplemented`, or another unsupported-method response depending on the client.
eth_blockNumber
Get the current block height on Ink. Essential for syncing dApps, monitoring transaction confirmations, and blockchain state tracking.
