What Is Devnet (Developer Network)?
Definition
A devnet is a test blockchain where developers can experiment with tokens, smart contracts, and DeFi without spending real money — using free test tokens instead.
Devnets (also called testnets) are copies of the main blockchain that use worthless test tokens. They let developers test their code before deploying to mainnet where mistakes cost real money.
- Solana Devnet — free SOL from faucets. Same SPL Token Program, same Metaplex, but no real value.
- Ethereum Sepolia — the primary Ethereum testnet. Free test ETH from faucets.
- Base Sepolia — Base L2 testnet. Same ERC-20 contracts work identically.
CoinDevTools operates on mainnet, not devnet. When you create a token, it's immediately real and tradeable. There's no "test mode" because the platform is designed for production launches.
Developers building custom integrations with CoinDevTools tokens should test on devnet first, then deploy to mainnet. The contract addresses and program IDs differ between devnet and mainnet.

Mainnet
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.
Smart Contract
A smart contract is a self-executing program stored on a blockchain that automatically enforces the rules of an agreement when predefined conditions are met.
Gas (Transaction Fee)
Gas is the fee paid to blockchain validators for processing transactions. On Ethereum it's measured in gwei, on Solana it's called a priority fee — both compensate the network for computation.
