The 60-day Bitcoin Lending Rate
What it costs to borrow USDC against Bitcoin for 60 days, discovered by competitive auction and settled on-chain.
60-day rate
Fitted from 15 active loans across the curve, with 4 observations in this tenor's own bin. This tenor is a point on that fit, not a quote — see the methodology on the pillar.
The auctions behind this number
Every point is a loan two parties agreed to and settled on Arbitrum. The rate is derived from those settlements, not asserted — the protocol is permissionless and open-source, and the underlying transactions are public.
24 scatter points back the current fit. The full set, with transaction references, is available over the API and in the protocol explorer.
What this rate is not
It is a point on a curve fitted across all tenors, so it carries the fit's uncertainty as well as its own sample's. It is a record of what cleared, not an offer, and not a rate you can transact at by reading this page. Where the market has not discovered a tenor, no page exists for it — we do not interpolate a number into a gap.
