SBOR on Stacks

Every morning, after the fixing, SBOR posts its benchmark lending rates to a contract on Stacks mainnet, so any Stacks contract, application or agent can read them on-chain. The table below is read live from Stacks by your browser, not from SBOR's servers. The same rates are also posted on Arc, Base, Hyperliquid and Solana.

Reading from Stacks mainnet…

Rates are effective annual rates, posted in basis points. From the fixing of 14 October 2026 (methodology 1.13.0), BTC-COLLATERAL-USD is SBOR's headline: what it costs to borrow any dollar stablecoin against plain bitcoin, across every eligible market SBOR reads, with BTC-COLLATERAL-USDC as its USDC rate. Before that date, BTC-COLLATERAL-USDC covered Morpho markets on Base, Ethereum and Arc. SBOR-USD, SBOR-BTC and SBOR-STX are SBOR's indices for lending on Stacks. Sizes are total supplied, in US dollars. A rate not in the latest fixing, such as an index withheld that day, is shown as such with the date it was last posted. On-chain, each rate keeps its last posted value and date, so a contract reading it should check the date.
