Description

Ruslan Fakhrutdinov from Extended Perp Exchange talks about building a unified margin across perps, vaults & yield, spot, and an integrated lending market. He explains critical components for a trustless perp DEX such as self-custody and on-chain solvency checks. Ruslan shares his experience with user acquisition programs, the total cost of execution vs. zero fees, and Extended's transparent fee model. We also discuss gauging sustainable product market fit in a post-airdrop environment and the roadmap for cross-asset collateral.
