Build on AEREDIUM.

EVM-compatible Layer 1. Your Solidity contracts deploy unchanged. Your existing tooling — Foundry, Hardhat, Remix, MetaMask, ethers.js, viem — works the way it always has.

Network parameters

Use these to add the AEREDIUM testnet to any EVM-compatible wallet, RPC client, or development framework.

Add to MetaMask

Open MetaMask, go to Settings → Networks → Add a network manually, and enter the parameters above. The chain ID and RPC URL are the only required fields. Once added, switch to AEREDIUM and any subsequent transactions will route through it.

Deploy a contract

With Foundry

# Compile your contract
forge build

# Deploy to AEREDIUM testnet
forge create --rpc-url https://testnet.rpc.aeredium.io \
  --private-key $PRIVATE_KEY \
  src/MyContract.sol:MyContract

With Hardhat

// hardhat.config.js
module.exports = {
  networks: {
    aeredium: {
      url: "https://testnet.rpc.aeredium.io",
      chainId: 1237,
      accounts: [process.env.PRIVATE_KEY]
    }
  }
};

// Deploy:
// npx hardhat run scripts/deploy.js --network aeredium

With ethers.js

import { JsonRpcProvider, Wallet, ContractFactory } from "ethers";

const provider = new JsonRpcProvider("https://testnet.rpc.aeredium.io");
const wallet = new Wallet(process.env.PRIVATE_KEY, provider);

// Your existing contract code, unchanged.
const factory = new ContractFactory(abi, bytecode, wallet);
const contract = await factory.deploy();
await contract.waitForDeployment();

RPC methods

AEREDIUM implements the standard Ethereum JSON-RPC interface. All eth_* methods work as you'd expect — eth_getBalance, eth_sendRawTransaction, eth_call, eth_getLogs, the full set. WebSocket subscriptions are available at wss://testnet.rpc.aeredium.io.
