Web 3 Dollar (USD3): Uses, Supply and Risks

Web 3 Dollar, or USD3, is a dollar-oriented stablecoin built as an RToken on the Reserve protocol. An RToken is a currency designed to be backed by assets held on-chain. USD3 is issued on Ethereum and Base; it is not the native token of either network. Its stated goal is to provide a stable-value asset that can be used in decentralized finance (DeFi), with a yield-bearing design. The project describes USD3 as fully asset-backed and overcollateralized, but public sources do not identify its specific backing assets or provide enough detail to assess their composition. USD3’s intended dollar value is not a guarantee that it will always trade at exactly $1. As of 2026-11-05, its reported price was about $1.12, illustrating that its market price can differ from its target.

USD3 is intended for people who want to hold a dollar-referenced token within DeFi rather than keep funds in a bank account or convert back to fiat currency. The project describes it as yield-bearing and says its design draws on DeFi markets. That does not mean holders receive a fixed or guaranteed return: yields can vary, and public sources do not specify a rate, payment schedule, or exact method by which yield reaches holders. RTokens also include minting and redemption mechanisms, while revenue sharing is part of the broader Reserve protocol design. The precise terms, eligible participants, fees, and operational steps for USD3 are not established here, so check current project documentation before relying on those mechanisms. USD3 may be useful as a DeFi asset, but its intended use and dollar reference do not remove smart-contract, market, or backing risks.

USD3 is available on Ethereum and Base. These are separate networks, so a token on one chain cannot automatically be sent to an address or application expecting it on the other. As of 2026-11-05, reported circulating and total supply were both about 1.34 million USD3. No maximum supply was specified. The reported market capitalization and fully diluted valuation were each about $1.5 million on that date; these figures can change as the token price and supply change. Supply can also depend on issuance and redemption activity, but public sources do not give a schedule for future issuance or a fixed cap. Before transferring USD3, confirm that your wallet, receiving service, and chosen network all support the same version of the token. A mistaken network selection can make funds difficult or impossible to recover.

USD3’s main risks include losing its dollar peg, a decline in value or liquidity of backing assets, and problems with the contracts or DeFi platforms involved in its design. The project says RToken governance is handled by RSR stakers and that governance should prioritize safety and stability. Governance can still make decisions that affect token holders, and this description is not a guarantee that backing is risk-free. The reported price of about $1.12 on 2026-11-05 was above the intended one-dollar reference, so holders should not assume an exact peg. For storage, use a wallet that supports the relevant Ethereum or Base token and protect its recovery phrase offline. Verify the network and token identity before receiving or sending funds, and be cautious of unsolicited claims or links about USD3. Self-custody puts responsibility for access and transaction security on you; custodial services introduce separate counterparty and access risks.
