TechFlow reports that Smile Finance, an on-chain derivatives protocol, has launched version 1.69 and released two new products: Synthetic AMM and Directional Impermanent Gain.
This AMM enables trading of fixed-rate options at market-driven prices based on the Black & Scholes model at any time. Directional Impermanent Gain offers higher capital efficiency and increased leverage on impermanent gains. The second and third phases of this release are forthcoming.
