Liquidity for Tezos Trading: scalable, on-chain, programmable

USDtez (Symbol: USDtz / USDTZ) is a USD-pegged stablecoin based on a fungible Tezos community standard — the FA token standard. USDtez is pegged to a formally-verifiable measure of (1:1 parity) value between itself and the United States Dollar (USD) providing a solvent, and scalable source of liquidity that is the ideal solution for low-fee Tezos-based asset trading.

3 main ways of getting USDtz


In most cases (for 'small amounts') you'll get your USDtz from an exchange. This includes AMMs (Automated Market Makers) like Quipuswap, and Smartlink Vortex, as well as cross-chain bridges like TezEx (Tezos Exchange)


If you want to buy USDtz for USDC 1-1 without the slippage or liquidity limitations of exchanges, and perhaps you are seeking enough funds to provide liquidity to those exchanges, using the services of a trusted mintery may be a better path


If you don't want to go through a Mintery, and would rather mint on your own, then you may qualify to enroll as an individual minter as a Mintery. (You may also qualify to create a Mintery yourself, especially if you are a Tezos baking service in good standing)

Features of USDtez


The USDtz model is designed to be the most scalable model for liquidity. Tezos (XTZ) trading volume has grown by a factor of over 100x since early-2019, outpacing its similarly valued network peers. and XTZ trading seems to be in a continuing upward trajectory even still. More exchanges are adding XTZ and more traders and investors are adopting it in their respective portfolios.

With great demand and growing volume, comes a need for great supply. Supply in this instance is a form of on-chain liquidity.


The process of minting USDtz begins with a collateral deposit of FIAT by an enrolled USDtz minter. FIAT collateral deposits may include certain other stablecoins (those which themselves can be confidently redeemed for FIAT cash). 

The USDtz reserve is audited monthly by Armanino LLP. Also, anyone in the world can audit USDtz's reserves in real-time, by comparing the minted supply with the collateral wallet. Check the reserve page for more.

Formal Verification

Formally-verified true price calculations demonstrated on-chain, protecting USDtz from manipulations and 'oracle attacks' that users of other stablecoins ultimately must endure. 

The balance between shifts in supply and demand of USDtz, including the size, and determination for minting and scaling of new USDtz is based on autonomously executed algorithmic response to formally-verified measures of real-world market data.

No Stability Fees

Many stablecoins charge stability fees or some form of that to keep the coin from under-collateralizing. Under-collateralization of a stablecoin, for however brief of a period, is what causes stablecoins to destabilize.  

Since USDtz is backed with full FIAT-based solvency, and since that solvency can be audited at any time by any user (check reserve page), such concerns are not applicable to USDtz. 

Therefore minters and users can hold USDtz without incurring any fees.


If you're trading XTZ and other Tezos-tokens, accept no substitute. USDtz's native on-chain nature makes it super gas-efficient, for the lowest fees.

USDtz is written on an optimized pure-Michelson smart-contract using the upgradeable FA Tezos-token-standard rendering the quickest most network-efficient swap, expending the least amount of gas. 

Programmable Money

USDtz's on-chain nature allows it to serve as programmable money — to support a wide-array of ecosystem applications in which remittance is executed through smart-contract-driven conditionals. These features are critical for financial instruments that depend on conditionals, such as bonds and derivatives.
