According to CoinMeta, as reported by Coindesk, Peter Thiel, which supports Founders Fund, led a $5 million purchase of the governance token ANVL for the DEFI collateral protocol Anvil. Pantera Capital, Theta Blockchain Ventures, Bullish, and Protoscale Capital also participated in the purchase. The transaction valuation and specific terms have not been disclosed. The tokens purchased came from Anvil's existing treasury, rather than being newly issued. Anvil is built on Ethereum and is primarily used to provide collateral guarantees for financial commitments such as payments and credit using digital assets. Its core model is similar to an on-chain letter of credit, and it does not require the mortgagor to borrow money or pay interest. During the same period, SDK was launched to help enterprises integrate with the protocol without having to write blockchain code.
