Streamflow announces USD+, a U.S. Treasury-backed stablecoin built on Solana that distributes daily yield directly to holders’ wallets. Designed for Web3 treasuries and crypto-native managers, USD+ enables users to earn yield on stable balances without staking or lockups. USD+ is backed by short-term U.S. Treasury Bills and is powered by M0’s universal stablecoin platform, where reserves are held by licensed custodians and independently verified. Rather than yield being retained by centralized issuers, USD+ is designed to pass Treasury bill yield on-chain to holders, daily, as additional tokens.
The product has been publicly announced and is coming soon, with a waitlist now open for early access. By holding USD+ in a Solana wallet, users are expected to earn a variable yield of approximately ~3.6% APY at the time of writing, distributed daily on-chain, without requiring staking or lockups. The yield rate is variable and will change over time based on market conditions and prevailing U.S. interest rates. USD+ is designed to maintain a $1 peg while remaining fully composable across the Solana DeFi ecosystem.
USD+ is powered by M0’s stablecoin infrastructure, where issuers lock verified collateral through the M0 Protocol to mint asset-backed stablecoins. U.S. Treasury holdings are transparently tracked and continuously monitored by validators to ensure full backing. Potential use cases include managing idle treasury balances while earning yield; settling payroll and contributor payments on-chain; holding capital between deployments without sacrificing composability; using USD+ as a yield-bearing settlement asset across DeFi protocols.
Once live, users will be able to swap assets such as USDC, USDT, or onramp fiat into USD+ directly through Streamflow’s interface, using popular Solana wallets. Fiat on-ramps are expected to support multiple currencies. Unlike rebasing stablecoins, USD+ is designed to remain composable across lending markets, liquidity pools, and on-chain applications. This allows users to earn yield while still retaining the flexibility expected from a modern stable asset.
