Deploy your first contract

Standard Ethereum tooling. No forks, no rewrites.

XDC is 100% EVM-compatible (chain IDs 50 mainnet / 51 Apothem). Point the tools you already use at the XDC RPC: your Solidity, ABIs and scripts work unchanged.

Hardhat

// hardhat.config.js — networks
xdc:     { url: "https://rpc.xinfin.network",  chainId: 50 },
apothem: { url: "https://rpc.apothem.network", chainId: 51 }

npx hardhat run scripts/deploy.js --network apothem

Foundry

# foundry.toml — [rpc_endpoints]
xdc     = "https://rpc.xinfin.network"
apothem = "https://rpc.apothem.network"

forge create --rpc-url apothem --chain 51 \ src/MyContract.sol:MyContract

Remix

Add XDC to your wallet on the Network page, then in Remix pick Injected Provider and deploy: your wallet signs against XDC. No plugin needed.

Need test XDC first? Grab it from the Apothem faucet (chain ID 51).

Coming from Ethereum?

It behaves like Ethereum. Here are the only deltas.

XDC runs the same EVM bytecode and Solidity, served over standard JSON-RPC by geth-based clients (that's what the modern-geth migration is). There are no XDC-specific opcodes or gas rules to learn. The differences are exactly three:

Chain IDs

Mainnet 50 (0x32), Apothem testnet 51 (0x33). Set these in your config; everything else is standard EVM.

Address prefix

XDC addresses are shown with an xdc prefix instead of 0x, a display convention only. The same 20-byte address works identically with 0x at the RPC and in tooling.

Fees & blocks

~2-second blocks and sub-cent gas. See the live gas price on the homepage rather than a hardcoded figure.
