Issuance
NUSD cycles through four distinct stages:
Pre-mined
Authorised
Issued
Redeemed
This article explains each of these stages and the associated onchain addresses users can publicly verify against.
Pre-mined
The majority of NUSD in circulation today is issued as NUSD•NUSD•NUSD•NUSD on the Runes protocol. Due to limitations with the Runes protocol, the deployer of a Runes token is not able to have sole power to mint or burn supply like on Ethereum with smart contracts.
Bamk.fi therefore chose a max supply of 2.1 quadrillion NUSD (2,100,000,000,000,000) that was 100% pre-mined and sent to Asigna multisig address:
bc1pfuluvkjcgzjdzjy42k3djkaw8a96dune2arcedhcml2h5sea6fdse9dajg
This gave Bamk.fi a supply that was essentially infinite with sole control of the issuance of NUSD tokens.
Pre-mined NUSD held at this address are not considered issued or circulating, and are therefore not backed by the equivalent USDe or delta-neutral position.
Authorised
Authorised NUSD are sent in large batches from the pre-mined NUSD to the following address:
bc1prnqh4uznxaklvxga6spr2fyjrpcxwnryzlhdpghzq9zqgz59z54qmentw6
The reason for Authorised NUSD is twofold:
To minimise how frequently Bamk.fi signer’s need to interact with private keys
The Bamk.fi Pre-mine address controls the ability for newly issued NUSD to circulate, so security of this address is our top concern. By issuing new NUSD in large batches we can greatly reduce how often private keys need to be used.
To meet customer demand at larger scale
Secondly, maintaining an inventory of Authorised NUSD allows us to scale operations and meet customer demand in a timely fashion. The authorisation process ensures that NUSD won’t need to be issued every time a new customer request is made. Instead, a balance of Authorised NUSD is kept ready to be issued when needed without having to touch the private keys for the Pre-mine NUSD. The balance of Authorised NUSD is determined by conversations Bamk.fi has had with clients and represents the anticipated demand for NUSD.
Authorised NUSD are not yet issued and not in circulation, so they are therefore not backed by the equivalent USDe or delta-neutral position and not counted in the market cap of NUSD.
All authorised NUSD are held in Bamk.fi’s treasury at the address(es) stated above and will not qualify for BAMK•OF•NAKAMOTO•DOLLAR rewards.
Issued
Issued NUSD tokens are in circulation and fully backed by sUSDe, USDe or USDT. A breakdown of the reserves can be seen here.
In order to provide liquidity for BTC/NUSD swaps, Issued NUSD may be temporarily backed by BTC while the protocol converts BTC to USDe/T.
Redeemed
Redeemed NUSD Runes are sent back to the pre-mine address at bc1pfuluvkjcgzjdzjy42k3djkaw8a96dune2arcedhcml2h5sea6fdse9dajg as part of the NUSD->USDE redeem.
Redeemed NUSD BRC20 are sent to a temporary deposit address then burned.
This ensures they are no longer counted in the NUSD market cap.
