Wrapped Bitcoin, or WBTC, is the first ERC-20 token backed 1:1 with Bitcoin. It is generated by fully-collateralizing BTC with a custodian and minting an Ethereum-compatible token that can be exchanged with other tokens. ERC-20 is a technical standard developed after the release of ETH that allows the tokens created on the Ethereum blockchain, such as ZRX, to interact with each other.
