Solver performance.

Flow concentrated on the BTC → WBTC route into Ethereum, which took 62.3% of weekly volume and gained the most share of any pair. Ethereum carried the large majority of settlement, with Base and Arbitrum splitting the remainder; the per-route table below shows the full distribution.

Net yield firmed alongside the heavier volume, annualizing to 10.38% BTC APY for the week against a trailing anchor of 8.42% BTC APY. A single week annualizes from a small sample, so the trailing figure is the better guide to the 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.

About the Bitcoin Solver. 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.
