In a direct response to the capital inefficiency plaguing crypto treasuries, Streamflow has unveiled USD+, a yield-bearing stablecoin backed exclusively by US Treasury bills. Announced by Malisha Stanojevic at Breakpoint, the product marks a significant strategic expansion for Streamflow, moving beyond its stronghold in token vesting and distribution to tackle the "lazy capital" problem that costs startups roughly 6% annually in inflation and opportunity costs.

The architecture of USD+ leverages M Zero (M0) middleware to ensure transparency and solvency—a critical differentiator in a market recently spooked by the collapse of opaque yield aggregators. unlike the "black box" strategies that have plagued DeFi, USD+ relies on what Stanojevic calls "pristine collateral": short-term US T-bills. The yield mechanism is designed for institutional inertia; it distributes returns daily to token holders automatically, eliminating the operational friction of staking, locking, or managing DeFi positions. This allows treasuries to remain liquid while generating revenue, effectively turning idle runway into a productive asset.

This move represents a formidable vertical integration for Streamflow. Having already processed token operations for over 30,000 projects—including heavyweights like Bonk, Zeus, and io.net—and reaching 1.5 million wallets, Streamflow effectively controls the "plumbing" of the Solana ecosystem. By introducing USD+, they are positioned to capture the value flowing through these pipes, offering existing clients a seamless upgrade from zero-yield USDC to yield-bearing assets without leaving the Streamflow dashboard. This transition from operational tooling to "Internet Capital Markets" signals a maturing Solana infrastructure layer, where capital efficiency becomes the new standard for survival.
