WBTC and WETH have both been in the news recently. Though they have similar sounding names, they are different in both composition and utility. WBTC is an Ethereum-based token (known as ERC-20) issues by BitGo, backed by Bitcoin. It allows users to use Bitcoin on the Ethereum network. Frequent listeners will recall that Mike Belshe, CEO of BitGo, joined us on a previous episode where he told us about BitGo's custody business. WETH is also an ERC-20 token, but in this case, it is backed by ETH rather than Bitcoin. Also, unlike WBTC, the collateral for wETH is held in a smart contract, not with a company. wETH allows users to use ETH more easily in DeFi and other Web3 applications. On this episode Andrew and Alex discuss the origins, use-cases and risks of these products and what they tell us about where Web3 is today.
