General Tips​

Security Best Practices​

  1. Never use mainnet private keys on testnet environments
  2. Create separate wallets for testing purposes
  3. Keep testnet and mainnet environments completely separate
  4. Don't share testnet private keys even though they have no real value

Development Workflow​

  1. Start with testnet for all development and testing
  2. Use local networks when possible (like Hardhat localhost, Solana test validator)
  3. Test thoroughly on testnet before considering mainnet deployment
  4. Keep track of testnet addresses and transactions for debugging

Common Issues​

  • Faucet rate limits: Most faucets have daily limits
  • Network congestion: Testnets can be slower than mainnet
  • Frequent resets: Some testnets reset data periodically
  • Different gas costs: Testnet gas costs may differ from mainnet

Note: All testnet tokens have no real value and are used solely for development and testing purposes. Never send real cryptocurrency to testnet addresses.
