Access Tezos EVM rollup An Etherlink RPC node provides applications with access to an EVM-compatible rollup on Tezos, enabling Ethereum developers to deploy contracts while benefiting from Tezos's proven consensus and Etherlink's decentralized sequencing. Etherlink bridges the Ethereum and Tezos ecosystems, combining familiar development experience with innovative rollup architecture. ### Why Etherlink on Tezos Tezos offers proven consensus, formal verification capabilities, and on-chain governance. Ethereum has the developers and tooling. **Etherlink combines both** — deploy Solidity contracts using familiar tools while leveraging Tezos's security and Etherlink's decentralized sequencing innovation. **Etherlink advantages:** - **Sub-second finality** — instant confirmation - **Decentralized sequencing** — no centralization - **EVM compatible** — standard Solidity development - **Tezos security** — proven consensus - **Low fees** — affordable transactions - **Smart Rollup** — innovative Tezos tech ### Tezos Smart Rollups **Smart Rollups** are Tezos's Layer 2 solution enabling arbitrary execution while settling to Tezos L1\. Etherlink is a Smart Rollup running EVM, providing Ethereum compatibility with Tezos security. The rollup's state and execution are verified by Tezos validators, inheriting L1 security guarantees. **How Etherlink works:** 1. Transactions executed on Etherlink (EVM rollup) 2. Decentralized sequencer orders transactions 3. State commitments posted to Tezos L1 4. Tezos validators verify rollup state 5. Benefits from Tezos consensus security ### Decentralized sequencing Most rollups use **centralized sequencers** creating censorship risks. Etherlink uses a **decentralized sequencer committee** preventing any single entity from controlling transaction ordering or censoring users. This maintains decentralization principles while achieving high performance. This combination positions Etherlink as infrastructure bridging Ethereum and Tezos with strong decentralization guarantees. ## Technical Documentation Quick start for developers ### Supported RPC Methods Etherlink supports all standard Ethereum JSON-RPC methods: - **eth\_blockNumber** — current block number - **eth\_getBalance** — XTZ balance - **eth\_call** — execute view functions - **eth\_sendRawTransaction** — broadcast transactions - **eth\_getTransactionReceipt** — transaction confirmation - **eth\_getLogs** — event logs - **eth\_gasPrice** — current gas price - **eth\_estimateGas** — gas estimation - **eth\_subscribe** — WebSocket subscriptions ### Code Examples 💻 #### JavaScript (ethers.js) — Etherlink Connection: ``` const { ethers } = require('ethers'); const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/etherlink/YOUR_API_KEY'); // Verify we're on Etherlink const network = await provider.getNetwork(); console.log('Chain ID:', network.chainId); // 42793 // Get XTZ balance const balance = await provider.getBalance('0x...'); console.log('XTZ Balance:', ethers.formatEther(balance)); // Deploy contract on Tezos rollup const factory = new ethers.ContractFactory(abi, bytecode, wallet); const contract = await factory.deploy(); await contract.waitForDeployment(); console.log('Contract on Etherlink:', await contract.getAddress()); console.log('Secured by Tezos with decentralized sequencing!'); ``` 💻 #### Python (web3.py) — Etherlink Setup: ``` from web3 import Web3 w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/etherlink/YOUR_API_KEY')) print('Connected to Etherlink:', w3.is_connected()) print('Chain ID:', w3.eth.chain_id) # 42793 print('Latest block:', w3.eth.block_number) # Sub-second finality gas_price = w3.eth.gas_price print(f'Gas price: {gas_price}') # Get XTZ balance balance = w3.eth.get_balance('0x...') print(f'XTZ: {balance / 1e18}') ``` 💻 #### WebSocket — Monitor Etherlink: ``` const { ethers } = require('ethers'); const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/etherlink/ws/YOUR_API_KEY'); // Monitor sub-second blocks provider.on('block', async (blockNumber) => { const block = await provider.getBlock(blockNumber); console.log(`Etherlink block ${blockNumber}: ${block.transactions.length} txs`); }); // Monitor decentralized sequencer const filter = { topics: [ethers.id('Transfer(address,address,uint256)')] }; provider.on(filter, (log) => { console.log('Transfer via decentralized sequencer:', log); }); ``` ### Etherlink Best Practices - **Fast Finality:** Design UX for sub-second confirmation - **Tezos Integration:** Leverage Tezos ecosystem benefits - **Decentralization:** Benefit from decentralized sequencing - **Bridge Usage:** Use official bridges for asset transfers - **Ethereum Tools:** Use standard development tooling - **Testing:** Test on Etherlink testnet before mainnet ## Why choose us?
