Alongside the launch, SUI Group Holdings seeded a newly launched suiUSDe vault with $10 million, marking one of the largest initial stablecoin deployments on Sui to date. The permissionless vault, operated by Ember Protocol and incubated by the Bluefin team, is designed to provide stablecoin-based yield to both institutional and retail participants. The vault has an initial capacity of $25 million, SUI Group said in a separate press release Thursday. Despite broad market weakness and waves of forced liquidations across crypto, decentralized finance’s total value locked (TVL) has held up, suggesting traders continue to seek yield and passive income even as bearish sentiment weighs on the market.

Unlike fiat-backed stablecoins, which typically move between venues as a neutral unit of account, synthetic dollars are built to operate natively inside trading and risk systems. Because they are part of the market itself, synthetic dollars can integrate directly with margin engines, liquidation logic and reward mechanisms. That allows them to act as active collateral and liquidity drivers, rather than passive settlement assets. Demand for that model has grown alongside the rise of yield and leverage-focused strategies, where users want capital efficiency and exposure in a single instrument. Ethena’s rapid growth has demonstrated that appetite, and bringing a similar structure to Sui extends it into a high-performance, programmable environment. DeepBook Margin, unveiled last month, is a key piece of that shift. By embedding margin trading directly into the liquidity layer, it allows synthetic dollars like suiUSDe to be used natively for leveraged trading, risk management and rewards within a single execution venue. “Launching the Ethena-backed suiUSDe was about establishing native, reliable dollar infrastructure on Sui,” said Marius Barnett, Chairman of SUI Group, in the release. “Seeding the suiUSDe Vault with $10 million is how we move that infrastructure into active use," he added. SuiUSDe was developed in collaboration with Ethena Labs and was first announced in the fourth quarter of 2025. With its mainnet debut, the asset is now available across multiple Sui-based protocols, including Aftermath, Bluefin, Cetus, Navi, Scallop, Suilend and others, broadening its use in trading, lending and yield strategies. Sui is a layer-1 blockchain developed by Mysten Labs, designed to support high-throughput transactions and programmable onchain assets.
