Prometheus Research Labs (PRL) is a software development team creating and implementing various DeFi protocols for the Buttonwood Foundation, including liquidity aggregation, price-stabilization wrappers, governance, peer-to-peer lending, and risk stratification. PRL’s approach to innovation focused on composability. The Buttonwood contracts are designed to be building blocks, not walled gardens. Thus, they are open-source and as minimal as possible—we seek to build primitives to be used by the entirety of digital finance, not platforms to extract value from the ecosystem. These protocols can be used and incorporated into any other protocol without restriction. We are a team of historians, engineers, and designers, united by the belief that DeFi is not yet the future of finance—it is still struggling to reproduce financial products that have been around for hundreds of years. To build the a new financial system, we must first first rebuild old finance in a truly decentralized form. Thus, our mission is historically inspired—financial innovation has proceeded in episodic bursts on the back of key inventions that rapidly spread in decentralized financial networks. Our vision is for the Buttonwood’s historically-tested primitives to catalyze a transformation in how DeFi works and help give birth to tradeable fixed-income markets, collateralized leverage tokens, and, eventually, a fully decentralized “dollar.”
