February 12 News, the Sui Foundation announced that the synthetic US dollar suiUSDe supported by the Ethereum ecosystem has officially launched on the Sui mainnet. This is the network’s first native synthetic US dollar asset, marking a significant step forward for Sui in decentralized financial infrastructure and providing new tools for on-chain leverage trading, lending, and liquidity strategies.
suiUSDe (also known as eSui Dollar) has been integrated into the Sui core financial system and is the first synthetic US dollar to receive support from DeepBook Margin. DeepBook Margin is Sui’s on-chain leverage and liquidity platform, offering unified clearing, risk control, and settlement modules. With this system, developers can quickly deploy financial products based on suiUSDe without building complex risk frameworks themselves.
Currently, major protocols such as Aftermath, AlphaLend, Bluefin, Cetus, Deeptrade, Navi, Scallop, and Suilend have synchronized support for this asset, enabling its direct use across multiple DeFi scenarios. SUI Group Holdings also participated in the launch, believing it will create more efficient foundational conditions for institutional capital operations and liquidity management.
suiUSDe was developed in collaboration with Ethena Labs, based on Ethena’s synthetic US dollar system. However, it is not a cross-chain bridged asset but is designed for native operation on Sui, aiming to reduce stablecoin fragmentation and improve capital utilization. Through deep integration with DeepBook Margin, this asset can support more complex portfolio strategies and hedging structures.
To accelerate ecosystem liquidity deployment, SUI Group has established an permissionless vault on the Ember protocol, injecting $10 million worth of suiUSDe, with an initial capacity of $25 million, open to institutions and retail investors. Adeniyi Abiodun, co-founder of Mysten Labs, stated that this case demonstrates the advantages of Sui’s composable architecture in lowering technical barriers.
With the landing of suiUSDe, Sui adds a key “US dollar cornerstone” to DeFi, which is expected to drive higher trading activity, deeper liquidity, and broader institutional participation.

Sky governance proposal implementation leads to approximately a 10% increase in SKY tokens, slowing down issuance and buyback mechanisms to strengthen the supply and demand structure
The native token SKY of the DeFi protocol Sky increased by approximately 10% after the governance proposal was implemented. The proposal reduces the token issuance scale over the next 180 days, slows down the release of staking rewards, decreases potential dilution pressure, and enhances the stability of the token's value. Meanwhile, Sky continues to repurchase SKY tokens, reducing market circulation, strengthening supply and demand, and promoting the development of the USDS stablecoin lending market. This strategy reflects the industry's general trend toward optimizing token economic models.
