The week in numbers.
Each week's settlement volume and the yield it earned.
Solver performance.
Volume and trade count moved up together, both stepping sharply above the prior week to set the highest readings of the trailing 8-week window. Activity concentrated on Arbitrum, which carried 62% of settled volume, with Ethereum accounting for most of the balance. The week was led by WBTC → BTC (Arbitrum → Bitcoin), which rose to 36.4% of volume from no activity a week earlier; two WBTC → cbBTC corridors also opened for the first time in the trailing window.
The week's raw settlement yield rose 2.66 bps from the prior week. Annualized, that is 12.89% BTC APY — but a single week annualizes from a small sample, so the trailing 8-week reading of 13.58% BTC APY remains the more representative anchor, and this week tracked just below it.

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.

The Solver is one of Maestro Institutional's curated BTC yield vaults — a permissioned, compliant strategy that earns by meeting cross-chain Bitcoin demand, taking deposits and paying distributions in native BTC. Qualified investors can review the terms and live performance on the vault page.
