Key differences

On posted APR, Arch (Standard) starts lower (7.25% vs 14.18%); whether that's the better deal depends on loan size and origination fees, both folded into the effective APR figures in our table above. Custody differs: Arch (Standard) uses qualified custodian, Unchained uses multisig collaborative, a meaningful distinction for any borrower who weighs counterparty risk against rate. Arch (Standard) offers a higher maximum LTV (60% vs 50%), which means more buying power per BTC pledged but a narrower buffer before liquidation if Bitcoin's price falls.
