Coldcard vs Relai

Coldcard (dedicated custody) and Relai (exchange and brokerage) serve different corners of the Bitcoin ecosystem, but the question that matters most is the same: who controls the keys? The scores are close — Coldcard at 81/100 (B+) and Relai at 78/100 (B+). When the gap is this narrow, the details matter: custody model, single points of failure, and the fine print on fees.

Where Each Platform Wins

Custody and security — the most heavily weighted category in our methodology at 35% — tilts 6 points toward Coldcard (88 vs. 82). On fees, Coldcard wins by 25 points. Coldcard charges ~$150 one-time compared to 1% - 1.5% at Relai. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators. Coldcard's strongest advantage is in transparency (95 vs. 65), where Coldcard's approach to proof-of-reserves and public documentation makes a measurable difference. Relai stands out on ease of use (88 vs. 72), reflecting Relai's user experience and onboarding flow.

The Custody Question

Both Coldcard and Relai have addressed the single-point-of-failure problem — neither relies on a single custodian or a single set of keys. That puts both platforms ahead of the majority of the industry. The difference comes down to implementation: Coldcard uses Hardware Wallet, while Relai uses Non-Custodial.
