#PSA for
#cashu wallet builders
mints are starting to move to keysets v2, which means wallets need to be up-to-date to support them too.
Although Cashu-TS (CTS) v2.7.0+ SUPPORTS keysets v2, you have to take steps to ensure your app is USING the tools in a keyset v2 supported way.
TLDR: Tokens containing Keyset v2 Proofs CANNOT be fully decoded without "help" because the token contains a shortened keyset ID. You MUST rehydrate them using Mint Keyset info.
If you are not already using CTS v3 for your wallets, I urge you to upgrade asap because it a) reflects the latest NUT specs and b) includes more quality of life tools for keysets v2.
