EVM compatibility

Every STRAT chain runs the Ethereum Virtual Machine and exposes the standard JSON-RPC interface. In practice, that means you build exactly as you would for Ethereum or Base — the only thing that changes is the network you point your tools at.

What carries over

• Contracts — Solidity (and other EVM languages) compile to the same bytecode; standards such as ERC-20, ERC-721 and ERC-1155 work as-is.
• Frameworks — Foundry and Hardhat for building, testing and deploying.
• Libraries — audited building blocks such as OpenZeppelin Contracts; client libraries such as viem and ethers.
• Wallets — any EVM wallet (MetaMask, Rabby, Rainbow, Safe…) can connect by adding the network.

Network details

Each STRAT chain has its own network parameters. Tools and wallets need:

• RPC URL
• Chain ID
• Native currency name and symbol
• Block explorer URL

Deploy with Foundry

# Values come from your chain's deployment details
export STRAT_RPC_URL="<your chain's RPC URL>"
export PRIVATE_KEY="<deployer key — never commit this>"

forge build
forge test
forge create src/Counter.sol:Counter \
  --rpc-url $STRAT_RPC_URL \
  --private-key $PRIVATE_KEY \
  --broadcast

Connect with viem

import { createPublicClient, defineChain, http } from "viem";

export const stratChain = defineChain({
  id: Number(process.env.STRAT_CHAIN_ID),
  name: "My STRAT chain",
  nativeCurrency: { name: "Gas token", symbol: "GAS", decimals: 18 },
  rpcUrls: { default: { http: [process.env.STRAT_RPC_URL!] } },
});

export const client = createPublicClient({ chain: stratChain, transport: http() });

const block = await client.getBlockNumber();

Add the network to a wallet

1. Open your wallet's network settings and choose to add a network manually.
2. Enter the network name, RPC URL, chain ID, currency symbol and block explorer URL for the chain.
3. Save, switch to the network, and verify the chain ID matches the official value before signing anything.

Good practice

• Keep RPC URLs, chain IDs and keys in environment variables, never in source control.
• Test on a testnet first, then deploy to your chain.
• Verify your contracts on the chain's block explorer once it is available.
