Cartha Testnet

Cartha Testnet is a public testing environment for the Cartha Subnet (SN35) that powers 0xMarkets DEX. The testnet allows miners, validators, and developers to test the full functionality of the Cartha subnet before deploying to mainnet.

Repositories:

• Miner CLI: cartha-cli

• Validator: cartha-validator

What is Cartha Testnet?

Cartha Testnet is a fully functional replica of the Cartha subnet running on Bittensor's testnet network. It provides:

• Real vault contracts deployed on Base Sepolia testnet

• Testnet TAO for subnet registration (no real cost)

• Testnet USDC for liquidity provision testing

• Full miner and validator functionality identical to mainnet

• Safe testing environment without financial risk

What Can You Do on Cartha Testnet?

For Miners (Liquidity Providers)

• Test liquidity provision without risking real funds

• Practice registration and hotkey management

• Experiment with different pools (BTCUSD, ETH/USD, EUR/USD)

• Use the Cartha Lock UI for a streamlined lock/unlock experience (no BaseScan needed!)

• View and manage positions through the web interface

• Extend locks and top up existing positions (currently in testing)

• Understand reward mechanisms and epoch cycles

• Test multi-pool strategies with testnet USDC

For Validators

• Test validator scoring logic and weight distribution

• Practice liquidation execution (when available)

• Test validator infrastructure and monitoring

• Understand epoch cycles and weight publishing

• Validate verifier integration and API endpoints

For Developers

• Test smart contract interactions with real vault contracts

• Use the Cartha Lock UI for testing the frontend lock flow

• Develop integration tools and automation scripts

• Test API endpoints and verifier functionality

• Build monitoring dashboards and analytics tools

• Experiment with different strategies safely

Testnet vs Mainnet

Key Differences

Feature	Testnet	Mainnet
Network	Bittensor testnet	Bittensor finney
Subnet UID	78	35
EVM Chain	Base Sepolia	Base Mainnet
Tokens	Testnet tokens (no value)	Real tokens (real value)
Cost	Free (testnet TAO)	Requires real TAO
Purpose	Testing & development	Production use

When to Use Testnet

• ✅ Testing new features before mainnet deployment

• ✅ Learning how the system works

• ✅ Developing integration tools

• ✅ Testing validator logic and scoring

• ✅ Experimenting with different strategies

When to Use Mainnet

• ✅ Ready for production deployment

• ✅ Want to earn real rewards

• ✅ Confident in your setup and understanding

• ✅ Have sufficient capital for minimum requirements

Common Issues

• Need testnet USDC: Visit https://cartha.finance/faucet to claim 1,000,000 USDC (24-hour cooldown between claims)

• Validator not whitelisted: Contact subnet owner

• Transaction failures: Check network (Base Sepolia), gas (testnet ETH), and balances

• Registration issues: Verify testnet TAO balance and network settings

• Wallet address mismatch: Ensure the wallet connected in the Cartha Lock UI matches the --owner-evm address specified in the CLI

• Extend/Top Up not working: These features are currently in testing - contact support if you encounter issues
