July 2025 – Cake Wallet (cake-tech/cake_wallet): Implemented a major API integration update for the Chainflip exchange provider, upgrading to the new endpoints for quotes and swaps. The changes revise the swap quote path and incorporate new parameters (numberOfChunks, chunkIntervalBlocks) into swap requests, plus a refined selection algorithm to consistently use the highest quote. This work aligns the wallet with external API updates, improving pricing accuracy, swap reliability, and resilience to upstream changes, ultimately delivering faster, more competitive trades for users.

Month: 2025-01 — Summary of work on shapeshift/web focusing on feature delivery, bug fixes, business value, and technical achievements. Key features delivered: - Chainflip Swap Retry Timing Alignment: Aligned retry behavior with the main Chainflip UI by increasing the default retryDurationInBlocks from 10 to 150 to ensure consistent swap retries across the app. This change reduces cross-component discrepancies and improves user experience during Chainflip swaps.
