Timeswap is a fixed time preference protocol for users to manage their ERC20 tokens over discrete time. It works as a zero liquidation fixed maturity money market and options market in one. Users can lend tokens into the pool to earn fixed yields. They can also borrow or leverage tokens against other tokens, without the fear of liquidation. Liquidity providers (different from lenders) create markets for any pair of tokens, adding liquidity, and being the counterparty to all lenders and borrowers of the protocol. In return, they earn transaction fees from both sides of the market. Timeswap utilizes a unique constant sum options specification and a duration weighted constant product automated market maker (AMM) similar to Uniswap AMM. It is designed to not utilize oracles, is capital efficient, permissionless to deploy, game theoretically sound in any state of the market, and is easy to use. It becomes the fundamental time preference primitive lego to build exotic and interesting DeFi products that need discrete time preference.

A Timeswap pool uses the Duration Weighted Constant Product automated market maker (AMM) similar to Uniswap. It is designed specifically for pricing of Timeswap options. Let 𝑥 be the borrow position with token0 as collateral, Let y be the borrow position with token1 as collateral. Let 𝑧 be the lending position per second in the pool. Let 𝑑 be the duration of the pool, thus 𝑑𝑧 is the total number of lending positions in the pool. Let 𝐿 be the square root of the constant product of the AMM. (𝑘 = 𝐿2) Let 𝐼 be the marginal interest rate per second of the Short per total Long. (𝑥 + 𝑦)𝑧 =𝐿 (square)
