Developer Tools

ValueChain is EVM-compatible. Point Foundry, Hardhat, Remix, Ethers.js, or Viem at the network endpoints. Solidity and Vyper deploy without a ValueChain-specific rewrite. The native currency is SOSO (18 decimals), not ETH.

Do not apply Ethereum confirmation depth. A receipt is inclusion. See Differences from Ethereum and Transaction Finality.

Add the chain to a wallet with Currency Symbol SOSO. See How do I add the ValueChain network?.

Foundry

[rpc_endpoints]
valuechain = "https://mainnet.valuechain.xyz"
valuechain_testnet = "https://testnet.valuechain.xyz"

forge create src/MyContract.sol:MyContract \
  --rpc-url https://mainnet.valuechain.xyz \
  --chain-id 286623 \
  --private-key "$PRIVATE_KEY"

Hardhat

networks: {
  valuechain: {
    url: "https://mainnet.valuechain.xyz",
    chainId: 286623,
  },
  valuechainTestnet: {
    url: "https://testnet.valuechain.xyz",
    chainId: 138565,
  },
}

Viem

import { defineChain } from "viem";

export const valuechain = defineChain({
  id: 286623,
  name: "ValueChain",
  nativeCurrency: { name: "SOSO", symbol: "SOSO", decimals: 18 },
  rpcUrls: {
    default: {
      http: ["https://mainnet.valuechain.xyz"],
      webSocket: ["wss://mainnet-ws.valuechain.xyz"],
    },
  },
  blockExplorers: {
    default: { name: "ValueChain Explorer", url: "https://main-scan.valuechain.xyz" },
  },
});

For testnet use id: 138565, https://testnet.valuechain.xyz, wss://testnet-ws.valuechain.xyz, and https://test-scan.valuechain.xyz.

Contract verification

View deployments on main-scan or test-scan. Verify source from the contract page in the explorer, or with Foundry:

forge verify-contract <address> src/MyContract.sol:MyContract \
  --chain-id 286623 \
  --verifier blockscout \
  --verifier-url https://main-scan.valuechain.xyz/api/

On testnet use --chain-id 138565 and --verifier-url https://test-scan.valuechain.xyz/api/.
