Summary of changes

New instructions:

  • CreateIdempotent: just like the normal Create that won't throw an error if the account already exists
  • RecoverNested: recover "nested" funds, where the funds are held by an account which is owned by an associated token account address

New features:

  • creating an account includes the InitializeImmutableOnwer instruction from the Token-2022 program, making all accounts created for Token-2022 immutably owned. This feature is not supported by the Token program.
  • during account creation, the program queries the token program to know the size of the target account using GetAccountDataSize. This is most useful for Token-2022, where tokens may require more space to accommodate extensions

Release

The program was released under feature flag FaTa17gVKoqbh38HcfiQonPsAaQViyDCCSg71AubYZw8, enable since epoch 334 on mainnet-beta.

Verification

Program verification uses the Anchor command-line interface, which can be installed by following the documentation.

The verification process builds the program in an Ubuntu container which contains the Solana CLI tools and its dependencies. More information can be found on the verifiable builds documentation.

From associated-token-account/program, run:

$ anchor verify --solana-version 1.10.33 -b debian -d ubuntu:20.04 --provider.cluster mainnet ATaYDmFSp5AgaJRGUcHeys4uF1wzCroXPeDgT7AcU82L
