What is a Mainnet?
USDC is a dollar-backed stablecoin that runs on multiple blockchains including the Ethereum blockchain, the Arbitrum blockchain, the Solana blockchain, and more.
Each of these blockchains have both main and test networks, or mainnets and testnets. Mainnets are the production blockchains that move and store digital assets, tokens, NFTs, smart contracts, and messages, while testnets enable developers to test their applications before deploying code on the mainnet.
Mainnet Tokens have Financial Value
Because the networks below are used to transfer financial value, take precautions to ensure you make any transfer. Precautions include testing your code, verifying addresses, ensuring your private key/s are safely used and stored.
Do not Test on Mainnets
Because mainnet blockchains move and store tokens that have financial value, do not do any testing on the mainnet blockchains.
