Tether Backs Stablecoin Round

Tether said on April 15 that it joined a $134 million financing round for Stablecoin Development Corporation, a public company focused on stablecoin infrastructure. (tether.io) The company trades on NYSE American under the ticker SDEV and said the January 16 private placement included R01 Fund LP, Framework Ventures, Tether Investments and Sky Frontier Foundation. SDEV said it issued pre-funded warrants tied to 167.5 million common shares, adjusted for a 1-for-5 reverse split. (stabledev.com) Stablecoins are digital tokens designed to hold a fixed price, usually one U.S. dollar, so they can be used to move money without the price swings of bitcoin or ether. Tether said total stablecoin circulation now exceeds $300 billion, while DefiLlama’s tracker showed about $320.7 billion on April 17. (tether.io) (defillama.com) SDEV is not pitching a consumer token. It said it is building an “on-chain holding company” that gives stock investors exposure to stablecoin networks, and The Block reported the raise was used to build a large position in Sky ecosystem tokens. (stabledev.com) (theblock.co) That matters because the money is going into the pipes rather than the packaging: settlement, custody, governance and compliance systems that let stablecoins move between users and platforms. Tether said attention has shifted to “the systems behind them,” while SDEV said its strategy is long-duration participation in protocol-level ecosystems with governance and risk controls. (tether.io) (stabledev.com) The scale of the market helps explain the timing. Bloomberg, citing Artemis Analytics, reported that stablecoin transaction volume reached $33 trillion in 2025, though McKinsey said only about $390 billion of that appears to be identifiable real-world payments rather than trading, liquidity moves or other on-chain activity. (advisorperspectives.com) (mckinsey.com) SDEV emerged from a corporate overhaul of NovaBay Pharmaceuticals, which changed its name to Stablecoin Development Corporation and switched its ticker from NBY to SDEV in early April. The company said it held about 2.06 billion SKY tokens as of March 16, and The Block reported that figure had risen to about 2.15 billion by March 31. (stabledev.com) (theblock.co) Sky, formerly MakerDAO, runs the USDS stablecoin and a governance token called SKY. The Block reported that USDS is the third-largest stablecoin by market value and the largest one that operates entirely on-chain, giving SDEV a direct bet on one of the sector’s biggest decentralized payment systems. (theblock.co) Paolo Ardoino, Tether’s chief executive, said stablecoins are already used “far beyond trading,” especially where local currencies are weak or payment rails are unreliable. The financing puts Tether alongside investors trying to build the back-end systems those users would need every day. (tether.io)
