Testnet

The StableNet Testnet is where you build and test. Use it to deploy contracts, run transactions, and verify integrations before going live.
ParameterValue
Chain ID8283
RPC URLhttps://api.test.stablenet.network
Explorerexplorer.stablenet.network
Faucetfaucet.stablenet.network
Block Time~1 second
Gas Limit105,000,000
The Testnet is reset periodically. Do not rely on it for persistent state.

​
Add Testnet to MetaMask

Open your browser console and run the following snippet, or use your wallet’s manual “Add Network” flow. 
await window.ethereum.request({
  method: "wallet_addEthereumChain",
  params: [
    {
      chainId: "0x205B",          // 8283 in hex
      chainName: "StableNet Testnet",
      nativeCurrency: {
        name: "KRC",
        symbol: "KRC",
        decimals: 18,
      },
      rpcUrls: ["https://api.test.stablenet.network"],
      blockExplorerUrls: ["https://explorer.stablenet.network"],
    },
  ],
});
You can paste this directly into your browser DevTools console on any page that has MetaMask injected.

​
Get Testnet Tokens

You need testnet KRC to pay gas fees.

Faucet

Request testnet KRC — no sign-up required.

Explorer

Verify your balance and transaction history.

​
Verify Your Connection

Run this from your terminal to confirm the RPC endpoint is reachable: 
curl -X POST https://api.test.stablenet.network \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
A successful response looks like: 
{"jsonrpc":"2.0","id":1,"result":"0x132d3"}
The result field is the current block number in hexadecimal.

​
Mainnet

Mainnet uses real KRC. Test all integrations on Testnet first.
