# US Sonic Dollar (USSD)

**Peg:** US Dollar

**Backing:** Real-World Asset Backed

**Governance:** Centralized (CeFi)

**Status:** active

## Overview

Sonic Labs's USSD is a permissionless, zero-fee stablecoin backed entirely by tokenized {{term:treasury}}Treasury{{/term}} bills, where yield flows to the Sonic ecosystem as buybacks rather than to holders. USSD is Sonic Labs' answer to why a fast EVM chain depends on Circle and Tether to denominate everything — a permissionless, zero-fee stablecoin backed entirely by tokenized {{term:treasury}}Treasury{{/term}} bills (BlackRock BUIDL, Superstate USTB, WisdomTree WTGXX) and built on Frax's frxUSD smart contract infrastructure. The design choice that distinguishes it from every other T-bill-backed stablecoin is also its most pointed: the {{term:rwa}}RWA{{/term}} {{term:treasury}}Treasury{{/term}} yield flows to the Sonic ecosystem as buybacks and incentives, not to USSD holders, meaning every dollar sitting in USSD generates a return that benefits the protocol's treasury while the holder earns exactly $1. At roughly $2M in circulation at launch, this subsidy is trivial; at meaningful scale, it becomes a permanent off-balance-sheet revenue stream funded by users who chose the zero-yield option. The GENIUS Act-compatible framing and U.S. jurisdiction signal suggest Sonic Labs is building for a regulatory environment that hasn't fully arrived yet, which will look prescient or premature depending entirely on how fast Washington moves.

## Collateral

Short-duration tokenized U.S. Treasury products held by approved custodians: BlackRock BUIDL (USD Institutional Digital Liquidity Fund), Superstate USTB (Short Duration U.S. Government Securities Fund), and WisdomTree WTGXX (Government Money Market Digital Fund); supported minting collateral also includes USDC, USDT, PYUSD, and USDB

## Peg Mechanism

1:1 permissionless mint and redemption via non-custodial smart contracts built on Frax's frxUSD infrastructure; users mint with any approved USD asset (USDC, USDT, PYUSD, USDB, BUIDL, USTB, WTGXX) at zero fee; redeem into any supported USD asset at any time with no lockup or withdrawal delay; cross-chain via CCTP; yield from Treasury reserves flows to the Sonic ecosystem rather than to USSD holders
