The bottom line
Both start near 7.25% to 7.49%, so the rate is close. Arch holds collateral with Anchorage, a qualified custodian, charges a 1.49% origination and 2% liquidation fee, and offers the loan two ways: a monthly-payment tier from around 7.25%, or a deferred-interest tier from around 8.0% where you skip the monthly payment and interest capitalizes. SALT holds collateral in its own pool, charges no origination fee, and offers 1, 3, and 5-year terms; rather than a traditional liquidation, it stabilizes an uncured margin call by converting your bitcoin to USDC (a 3% fee, plus 2% to convert back), which keeps the loan open but locks in a downturn price. Choose Arch for independent custody or the deferred structure; choose SALT for long fixed terms and no origination fee.

Leverage, limits, and speed
SALT allows the higher maximum LTV (70% vs 60%), so you can borrow more per Bitcoin, at the cost of a thinner buffer before a margin call if the price falls. Funding runs same day to 1 day at Arch and 1–2 days at SALT.

- Zero rehypothecation, explicit policy
- Segregated wallets
- $75M raised (2024)
- 1.5% origination fee plus 2.5% liquidation fee

SALT
- Operating since 2016

- International availability: Australia, Canada, Brazil, Portugal, Switzerland, UK, UAE, Vietnam
- Lender-held custody, not a third-party qualified custodian
- If a margin call goes uncured, Salt stabilizes the loan (converts collateral to USDC, a 3% fee, with a 2% fee to convert back later) rather than running a traditional liquidation, so you keep the loan and choose how to proceed; the cost is that stabilization locks in a downturn price
- SALT Shield (a paid downside-protection add-on) can forbear margin calls and market-triggered stabilization for the life of the loan
