Allows a token manager to lock hashes for the factory, default token and all minted tokens as well as any token minted afterwards.

Technical Behavior

The required authorization is the token_factory_manager as the manager is responsible for updating the data.

token_factory_id is required and must exist.

RAM usage

  • Adding uri and hash will consume certain bytes depend on how many data are added.

    • RAM usage is covered by eosio.nftram. But this action will fail if the unused RAM of eosio.nftram is less than or equal to 200MB.

    • If the RAM usage is exceed token maximum pack size of 384 bytes, action will fail.

  • Updating or remove meta data which result in no bytes is added, there will be no restriction.
