Buttonwood

Buttonwood is a collection of DeFi primitives for building powerful decentralized financial instruments such as liquidation-free debt, convertible bonds, options, fiat-free stablecoins, and more. Buttonwood's permissionless core contracts are easy to use-developers need only to build routers and a UI. Buttonwood's financial primitives are the building blocks of the DeFi stack. Besides AMMs (Uniswap, SushiSwap) and margin lending (Aave, Compound), DeFi is still missing parts of the financial stack. Rather than copy traditional financial approaches, Buttonwood allows developers to build DeFi bonds, stablecoins, and structured products without margin calls or liquidations.
