What Is Mainnet?
Definition
Mainnet is the live, production blockchain where real transactions with real value occur — as opposed to testnets (devnet, Sepolia) which use fake tokens for testing.
Mainnet is the "real" blockchain. When you create a token on CoinDevTools, it deploys on mainnet — the token has real value, real transactions cost real money, and everything is permanent.
- Mainnet — real tokens, real money, permanent transactions. Where your live project operates.
- Testnet/Devnet — free test tokens (no real value), used for development and testing. Solana Devnet, Ethereum Sepolia, Base Sepolia.
- Solana Mainnet-Beta — the production Solana network
- Ethereum Mainnet — the production Ethereum L1
- Base Mainnet — the production Coinbase L2
Before deploying to mainnet, developers test on testnets. CoinDevTools handles all the mainnet deployment for you — no need to configure RPC endpoints, chain IDs, or network settings.
