Solver performance.
The Starknet corridor led for a second week, with 78.3% of volume, and this week the flow ran both ways. BTC → strkBTC carried 52.2%, and the return leg, strkBTC → BTC, rose to 26.0% from 12.5% the week before. The NEAR Intents routes made up the remainder, led by nBTC → WBTC (Ethereum), while smaller routes accounted for a larger share of the trade count than of volume.
The vault returned 30.8 bps over the week, net of all fees, which annualizes to 18.6% BTC APY. A single week is a small sample; since October 5, net yield stands at 18.7% BTC APY, and both weeks have been positive.

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. Yield is the change in the gmBTC vault's on-chain share price over the period, so it reflects every entry the vault records in that period, not only the period's trading. Because a single week is a small sample, the trailing four-week and since-October figures are the more reliable measure of performance.
