The week in numbers.
Each week's settlement volume and the yield it earned.
Solver performance.
Flow concentrated in WBTC → BTC (Ethereum → Bitcoin), which climbed 263.3% on the week to 52% of volume and became the most-traded pair. Its return leg, BTC → WBTC, absorbed most of the balance, while Base-chain routes stayed marginal — Ethereum-side settlement accounted for 99.5% of the total.
Realized yield firmed over the week and annualizes to 17.82% BTC APY, but a single week off a 3-week base overstates the run rate. The trailing 3-week figure of 9.87% BTC APY remains the fairer anchor for the product's yield.

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.
