Networks

---

This page lists the T-REX network environments and everything you need to point a wallet or developer tooling at them.

The current live environment is InGen, the public testnet of the T-REX Ledger, the reference chain and golden source of T-REX Network. Mainnet endpoints will be published here once available.

⚠️ InGen is a test network. TREX on InGen is a test token with no monetary value, and network state may be reset at any time. Do not use it for production assets or data you cannot afford to lose.

InGen testnet

InGen is a Polygon CDK chain running the OP Stack execution client (op-geth), connected to the AggLayer. It is public and permissionless, with a ~1 second block time. It settles to Ethereum sepolia and interoperates with other ecosystems through the AggLayer.

Add InGen to your wallet

Manually (MetaMask and most EVM wallets): open the network selector, choose Add a custom network, and enter the values from the table above.

Programmatically via EIP-3085:

await window.ethereum.request({
  method: 'wallet_addEthereumChain',
  params: [{
    chainId: '0x58F0D', // 364301
    chainName: 'T-REX InGen Testnet',
    nativeCurrency: { name: 'TREX', symbol: 'TREX', decimals: 18 },
    rpcUrls: ['https://rpc.ingen.t-rex.network'],
    blockExplorerUrls: ['https://explorer.ingen.t-rex.network'],
  }],
});

Test TREX

You need test TREX to pay for gas on InGen. Get it from the faucet at faucet-ingen.t-rex.network.

The faucet dispenses 0.1 TREX per request, once every hour per address.
