MetaMask JSON

For programmatic wallet-add flows or copy-paste convenience:

{
  "chainId": "0xba",
  "chainName": "OXN Testnet",
  "rpcUrls": ["https://rpc.bout.network"],
  "nativeCurrency": {
    "name": "TBLUAI",
    "symbol": "TBLUAI",
    "decimals": 18
  },
  "blockExplorerUrls": ["https://explorer.bout.network"]
}

Reset policy

Testnet may be reset during development phases. When a reset is planned, an announcement is posted via the Support channels. Reset behavior:

• All account balances are cleared.
• Deployed contract addresses become invalid.
• Chain ID and endpoint URLs remain the same across resets.

Design your test workflows around the possibility of a reset: keep deployment scripts idempotent, and don't hard-code contract addresses across environments.
