The week in numbers.
Each week's settlement volume and the yield it earned.
Solver performance.
Volume concentrated almost entirely on the Ethereum corridor, which handled 99.2% of settlement and left Base a marginal remainder. Within that, BTC → WBTC and WBTC → BTC — the two directions of the same WBTC pair — split the week roughly evenly and together accounted for nearly all flow.
The week's raw settlement yield printed at 11.94 bps, below the recent run rate, and a single week annualizes from too thin a sample to read as a rate of return. Set against the trailing four-week annualized yield of 18.44% BTC APY, the return profile held even as the week itself came in soft.

Credit programs.
Mezzamine Mining Loan I remains active and fully deployed to the borrower, with repayment underway in native Bitcoin; 5% of principal has been returned so far. Because both the deposit and the repayments settle in BTC, the program carries no currency mismatch between the capital committed and the yield it returns.
About.
About this report. The Bitcoin Solver provides settlement liquidity for cross-chain Bitcoin flow, earning a spread on each completed settlement. Every figure here is a realized, BTC-denominated result, net of fees — not a quoted or projected rate. Because a single week is a small sample, the trailing four-week and since-inception figures are the more reliable guide to expected performance. This edition was published retrospectively at the launch of the Weekly Report; all figures are computed as of the week shown.
