# Coin Contract

The ChallengeCoin contract is an ERC20 token with a total supply capped at 1 billion tokens, ensuring scarcity and value stability. Built using OpenZeppelin's ERC20 framework, it provides a secure and reliable token for the Challenge.GG ecosystem. The contract assigns initial token ownership to a multisig wallet, enhancing security and governance by requiring multiple approvals for key transactions.
