Solana programs developed at Paxos
minter_controller is used to add transaction controls to Solana mint authorities for the token and token-2022 program.
The transaction controls include rate limitings and whitelisting. The program requires the token mint authority
to be a spl token multisig.
Audits were performed by both Zellic and Trail of Bits. Audit reports can be found here.
The program is first used by calling the add_minter instruction which creates a PDA that can be used to mint tokens.
The PDA is derived from the minter_authority and mint_account.
The minter PDA should be added as a signer on the spl token multisig.
An admin Pubkey is also specified to update the transaction controls.
Whitelisted addresses which can be minted to can be added via add_whitelisted_address. Whitelisted addresses can be
removed via remove_whitelisted_address. These instructions can only be called by the admin.
The initial rate limit is specified when calling add_minter. It can also be updated via update_rate_limit.
These instructions can only be called by the admin.
Updating the admin is a two step process. Step 1 is to call start_admin_transfer with the current admin.
Step 2 is for the new admin to call accept_admin_transfer.
Minting tokens is done by calling mint_tokens. This instruction must be signed with the minter_authority.
