Network & RPC Endpoints

This is the primary environment for builders to experiment, deploy trial contracts, and integrate Relix into their applications.

Network details

• Name: Relix Testnet

• Chain ID: 4127

• Native currency: RLX

• RPC URL: https://rpc-testnet.relixchain.com

• Block explorer: https://testnet.relixchain.com

You can apply these values in:

• EVM wallets (MetaMask, Rabby, OKX Wallet, etc.)

• Development frameworks (Hardhat, Foundry, Truffle)

• Backend services that talk to the chain via JSON-RPC

As more environments (e.g. mainnet, staging networks, or dedicated archives) go live, they can be added to this list with the same structure.

JSON-RPC usage

The Relix RPC behaves like a typical EVM endpoint:

• Uses HTTPS over standard JSON-RPC

• Accepts common methods such as eth_call, eth_sendRawTransaction, eth_getLogs, eth_getBlockByNumber, and so on

• Returns chain-specific values (block numbers, gas prices, balances) for chain ID 4127

For most clients, you only need to swap the RPC URL and chain ID:

• In a wallet, this means adding Relix Testnet as a custom network.

• In backend code, this usually means changing a single RPC_URL environment variable.

If your application performs heavy operations (for example, broad log scans or historical indexing), it is good practice to:

• Cache frequently used data where appropriate

• Limit very large eth_getLogs ranges

• Monitor how the RPC behaves under your workload and adjust polling intervals accordingly

Example configuration (for developers)

Below is a minimal example of how a typical client would be configured to talk to Relix Testnet. The exact syntax will differ by library and language, but the parameters are always the same:

// Pseudo-config for an EVM client

export const RELIX_TESTNET = {
  chainId: 4127,
  name: "Relix Testnet",
  nativeCurrency: {
    name: "Relix",
    symbol: "RLX",
    decimals: 18,
  },
  rpcUrls: {
    default: {
      http: ["https://rpc-testnet.relixchain.com"],
    },
  },
  blockExplorers: {
    default: {
      name: "Relix Testnet Explorer",
      url: "https://testnet.relixchain.com",
    },
  },
};

Any framework that supports custom EVM networks can be pointed at Relix by supplying this information.

Verifying connectivity

After configuring your wallet or client:

1. Make sure the active network reports Relix Testnet with chain ID 4127.

2. Query a simple RPC method such as eth_blockNumber or view your address on https://testnet.relixchain.com.

3. Confirm that the response includes recent blocks and a non-error status.

Once these checks pass, your setup is ready for deploying contracts, interacting with dApps, and integrating Relix into your product stack.
