Jan 1, 2026January 2026 — chainflip-io/chainflip-sdk-monorepo: Focused on reliability and correctness of swap status retrieval. Key feature: added maxOraclePriceSlippage to fillOrKillParams to improve status accuracy. Bug fix: ensured maxOraclePriceSlippage is returned when available on getStatusV2 (WEB-2960, PR #1490). This work increases swap predictability and reduces failure modes, improving user trust and throughput. Technologies: TypeScript/SDK development in a monorepo with commit-based traceability.

Oct 1, 2025Month: 2025-10 Consolidated summary for chainflip-sdk-monorepo focusing on BTC swap reliability improvements. Key features delivered: - BTC Swap Retry Duration Enhancement: increased the recommended BTC retry window from 15 minutes to 30 minutes to improve reliability for BTC swap operations. Affects QuoteRequest.ts and related test snapshots. Commit: 0d42dc8a2df2a7cb528e75b50c50c0c146564d09 (PR #1442). Major bugs fixed: - Updated and fixed test snapshots to align with the new 30-minute window, addressing test failures and CI noise related to the duration change. Overall impact and accomplishments: - Improved reliability and predictability of BTC swap flows, leading to smoother user experiences and fewer failed swaps due to tight retry windows. - Demonstrated end-to-end impact across the SDK monorepo with a single, well-scoped change. Technologies/skills demonstrated: - TypeScript code changes in QuoteRequest.ts, test snapshot maintenance, and monorepo coordination; strong change hygiene with clear commit messaging and traceability. Business value: - Higher BTC swap success rates, reduced support friction, and increased user trust in the BTC swap experience.

May 1, 2025May 2025: Delivered targeted performance optimization for the Swap module in chainflip-sdk-monorepo by adding database indexes to Swap.nativeId, SwapRequest.nativeId, and SwapFee.swapRequestId. This optimization reduces query latency for swap lookups and fee assessments, enabling higher throughput for swap operations and better scalability. Commit: 5b4ec1cd14a9a2e2052c7b424bc887db3b6e58c4 (chore(swap): add indexes to swap, swapFee and swapRequest tables) in repo chainflip-io/chainflip-sdk-monorepo. Impact expected to improve queries across the swap lifecycle and support growing user demand.
