WCTC is a wrapped ERC-20 version of native Creditcoin (CTC), enabling holders of mainnet CTC to access Ethereum-based liquidity. Users can swap native CTC for wCTC at a 1:1 ratio through the Creditcoin Foundation's swap tool, and trade wCTC against G-CRE on Uniswap, providing an additional path for mainnet token holders to access market liquidity.
