Technical Primitives

USDh and sUSDh are issued natively on Bitcoin L1 on Runes and Bitcoin L2 on Stacks.

Runes

We use PSBTs to mint and stake. No bridges, L2s, or altcoins are involved.

For more information on the Runes supply, please refer to the USDh and sUSDh addresses and etchings below.

USDh & sUSDh Runes Protocol Addresses and Token Etchings

Protocol Addresses

• USDh & sUSDh Cold Wallet: bc1q24t48s4lyks0309u9arqtqcrj5txc73pf6xfuxcfdgznz92wewvs8lr8re

• Protocol Address 1: bc1ppd9xd0dgnt88wfxv4fudy407y4mvq8ar62r5xw9yrlzsfxxcr96sskfd2w

• Protocol Address 2: bc1p7s7qa93gckae09lmvxpqm6j7xeva6a0pstu53397s7te86jeygxss0f0a4

Token Etchings

• USDh Token Etching: USDH•USDH•USDH•USDH

• sUSDH Token Etching: SUSDH•SUSDH•SUSDH•SUSDH

The Runes protocol requires the entire token supply to be defined in the initial etching transaction. Both USDh and sUSDh have a total supply of 10 trillion tokens, stored in the protocol's reserve. Tokens enter circulation through minting and staking.

The circulating supply is verifiable on-chain by subtracting the tokens held in the reserve and protocol wallets from the total supply: Circulating supply = 10 trillion - reserve wallet - protocol wallets

Stacks

We use Clarity based smart contracts to issue SIP-10 USDh and sUSDh on the Stacks blockchain.
