Testnet (TRON Nile)

BCO Protocol contracts are deployed on the TRON Nile testnet for development and integration testing.

Contract Addresses

Contract	Nile Testnet Address	Type
BCOToken	TBD	Immutable
DeedRegistry	TBD	UUPS Proxy
BCOStaking	TBD	UUPS Proxy
TimelockController	TBD	Immutable

Connecting to Nile

TronLink Wallet

1. Open TronLink browser extension
2. Click the network selector (top right)
3. Select Nile Testnet
4. Your wallet address is the same across networks

TronWeb Configuration

const TronWeb = require('tronweb');

const tronWeb = new TronWeb({
  fullHost: 'https://nile.trongrid.io',
  headers: { 'TRON-PRO-API-KEY': 'your-api-key' },
  privateKey: 'your-private-key'
});

Hardhat Configuration

// hardhat.config.ts
networks: {
  nile: {
    url: 'https://nile.trongrid.io/jsonrpc',
    accounts: [process.env.DEPLOYER_PRIVATE_KEY],
  }
}

Getting Test TRX

Test TRX for the Nile network can be obtained from the official TRON faucet:

1. Visit the Nile Faucet
2. Enter your TRON wallet address
3. Complete the verification
4. Receive test TRX (usually 10,000 TRX)

Differences from Mainnet

Parameter	Nile Testnet	Mainnet
Network ID	Nile	Mainnet
TRX	Test tokens (no value)	Real tokens
Block time	~3 seconds	~3 seconds
Explorer	nile.tronscan.org	tronscan.io
API endpoint	nile.trongrid.io	api.trongrid.io
Admin transfer delay	Shorter (for testing)	48 hours
Timelock delay	Shorter (for testing)	72 hours

Testing Workflow

1. Get test TRX from faucet
2. Connect to Nile in TronLink
3. Interact with testnet contracts
4. Verify behavior matches documentation
5. Deploy to mainnet when ready

All contract functions, events, and errors behave identically on testnet and mainnet. The only differences are configuration parameters (delays, limits) which may be set to shorter values on testnet for faster testing cycles.
