SPL Token 2022 - v1.0.0

What's new

With the last Token-2022 audit complete, the program is ready to enter its first
major version with v1.0.0!

Audits

All audits are hosted at https://github.com/solana-labs/security-audits#token-2022.

Verification

This build provided on the release uses solana-verifiable-build.

You can verify it by checking out the repo at commit 15ebdb6 and running:

$ solana-verify build --library-name spl_token_2022 -- --no-default-features

The --no-default-features flag ensures that the unsupported zero-knowledge proof functionality and the unaudited token-group functionality is omitted. Once the program is built, it's possible to verify it by running:

$ solana-verify get-executable-hash target/deploy/spl_token_2022.so
d941635f5df9dcb42e2fd7f25149051048dd27d02c7cb8dbb7a9e39933722fd3
