Firefish uses non-custodial escrow (3-of-3 pre-signed transactions), which means your Bitcoin requires multiple key holders to coordinate, reducing single-point-of-failure risk. SALT uses custodial. In a platform insolvency scenario, Firefish borrowers' collateral is protected by the multisig architecture, while SALT borrowers may face creditor claims.
