Spectra Pool Migration Notice We have launched new pools under the updated “Curve SNG” architecture to replace those previously deployed using the legacy AMM model, which is now being phased out. These new pools offer improved fee capture for LPs, better liquidity concentration, and streamlined PT/YT naming. They are now live, and a one-click migration tool is available in the Spectra App, accessible via the side menu and Portfolio. What’s changing: Legacy pools, labeled in the App simply as "Curve" are being phased out and will no longer appear on the main Pools page. They remain accessible via Product pages, including redemptions and exits through the Portfolio. We recommend that LPs migrate their positions to the new pools for optimal performance and long-term support. Why now? We’ve received reports of slightly lower-than-expected LP token value redemptions (approx. 0.5% to 3%) at maturity in rare corner cases within the legacy AMM design. While reports so far have been limited to a single, now-expired pool, the underlying issue could theoretically affect liquidity providers in other legacy pools under very specific conditions. The team is closely monitoring all remaining legacy pools and is now taking proactive steps by encouraging LPs to migrate to the new Curve SNG-based pools, which are immune to this type of edge case by design. We are in direct contact with the Curve team and users who have reported this issue, and we are resolving it on an individual basis. Details on legacy AMM pools • Now hidden from Pool pages; remain fully accessible via Product pages • PT and YT swaps remain fully available, along with standard redemption and withdrawal flows LPs may choose to migrate to the respective new pools, but are not required to do so. They can still withdraw their positions as usual at any time or continue providing liquidity until the old pool expires. Over half of all Spectra pools are now powered by the new Curve SNG design (launched April 29, 2025) - and continue to operate as usual. For any assistance during the migration, please reach out via the Discord ticket system.
