The week in numbers.
Each week's settlement volume and the yield it earned.
Solver performance.
Flow stayed on the inbound leg, where Bitcoin is wrapped for use across networks. BTC → WBTC led at 32.6% of volume, with the Ethereum and Base wrap routes close behind, and Arbitrum and Ethereum together carrying most settlement. The one route to expand was the Ethereum return leg, WBTC → BTC, which rose 117.5% off a smaller base.
Yield tracked the lighter volume lower. The week annualized at 7.53% BTC APY, below the trailing four-week average of 10.57% BTC APY — a reminder that any single week annualizes from a small sample, and the trailing figure better reflects the protocol's run-rate.

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.
