Bitcoin Solver performance
Bitcoin Solver settled 1.0562 BTC across 14 trades over the week, a step down from the prior week's elevated activity. The pullback followed an unusually busy stretch rather than any change in the protocol itself, and settlement continued to accrue yield through the quieter tape. Flow stayed concentrated on the Ethereum corridor, where both WBTC legs carried nearly all of the volume.

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.

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.
