In DeFi, despite having robust money market protocols, there are numerous inefficiencies that need addressing to achieve the promise of superfluid collateral. The concept of superfluid collateral was introduced in 2019 to improve the capital efficiency of DeFi protocols by utilizing collateral in idle Maker CDPs and ERC-20 liquidity tokens from Uniswap in other lending/borrowing markets. Since then, DeFi has grown exponentially, but there is still a lack of decentralized identity and reputation scores for under collateralized lending. Over-collateralization is the solution for securing lenders' assets, but it has its inefficiencies, such as non-standard collateralization of assets, governance overhead, and expensive oracles. Timeswap, a market-driven collateral pool, aims to improve capital efficiency by enabling users to choose their preferred collateralization level and allowing communities to self-organize to increase value without external influence. The maturity period of a pool is the differentiating factor for capital provisioning, and the convergent horizon is its event horizon, acting as a liquidity black hole that attracts liquidity to the pool with the most favorable parameters. This push for capital efficiency is also evident in the wider crypto ecosystem, with Uniswap v3, Osmosis, Hashflow, and Element Finance adopting different approaches to improve capital efficiency. These initiatives signal a new era of capital efficiency in DeFi.
