SUI Group Launches eSUI (suiUSDe) with Ethena and Advances Institutional Adoption Through the suiUSDe Vault on Ember Protocol and Bluefin

Key Terms

synthetic dollar financial

A synthetic dollar is dollar exposure or funding created through financial contracts (such as currency swaps, forwards or other derivatives) instead of holding actual U.S. cash or bank deposits. It matters to investors because it can provide a cheaper or faster way to get U.S. dollar access, but it brings extra risks—like dependence on counterparties, contract rollovers and changing market terms—similar to borrowing a friend’s car instead of owning one, which can affect funding costs and asset prices.

stablecoins financial

Stablecoins are a type of digital currency designed to maintain a steady value, often linked to traditional currencies like the dollar or euro. They function like digital cash that offers the convenience of online transactions while avoiding the large price swings common with other cryptocurrencies. This stability makes them useful for investors and users who want a reliable way to store and transfer value without exposure to sudden market changes.

permissionless technical

A permissionless system lets anyone participate, access, or build on a platform without needing prior approval from a central authority — like an open park anyone can enter rather than a gated club. For investors, permissionless models matter because they can accelerate adoption and innovation by lowering barriers to entry, while also increasing competitive pressure and regulatory or security risks that can affect value and stability.

Mainnet technical

The mainnet is the live, operational blockchain where real tokens, transactions, and smart contracts run and have actual economic value. Think of it as the public road where vehicles carry customers and goods rather than a private test track; for investors, a project launching or migrating to mainnet signals higher maturity, real usage, and exposure to operational risks, token supply changes, and network security that can affect value.

on-chain technical

On-chain describes actions or data that are recorded directly on a blockchain, a public digital ledger that creates a permanent, time-stamped record of transactions. For investors, on-chain activity provides verifiable evidence of transfers, ownership changes or automated program actions (like contract-driven payments); seeing these entries is like checking a bank statement and helps assess liquidity, settlement finality, fees, and transparency when judging risk and market behavior.

vault financial

A vault is a highly secure storage space—physical or digital—used to protect valuable assets such as cash, documents, data, or digital tokens. Think of it as a fortified safe or bank deposit box with strict access controls and backup systems; for investors, a vault matters because it reduces the risk of theft, loss, or data breach, supports regulatory compliance, and helps preserve the value and integrity of assets held by a company.

WAYZATA, Minn.--(BUSINESS WIRE)-- SUI Group Holdings Limited (NASDAQ: SUIG) (“SUI Group,” “SUIG” or the “Company”) today announced that its native synthetic dollar, eSui Dollar (suiUSDe), is now live on Sui Mainnet. Additionally, SUI Group announced the deployment of $10 million in newly minted suiUSDe into a yield-generating vault operated by Ember Protocol, a vault and investment infrastructure provider incubated by the team behind Bluefin.

As previously announced in October 2025, SUI Group partnered with Ethena Labs and the Sui Foundation to launch suiUSDe and USDi as the first native stablecoins built for the Sui ecosystem. With suiUSDe now live, SUI Group is transitioning from launch to utilization by committing capital into on-chain yield infrastructure designed to support scalable, permissionless participation.

The newly launched suiUSDe Vault is a permissionless, yield-generating vault backed by suiUSDe and built natively on Sui. SUI Group acted as the anchor participant by seeding the vault with $10 million, supporting its role as a foundational liquidity layer for stablecoin-based yield on Sui. The vault has an initial capacity of $25 million and is open to both institutional and individual participants.

“Launching the Ethena-backed suiUSDe was about establishing native, reliable synthetic dollar infrastructure on Sui,” said Marius Barnett, Chairman of SUI Group Holdings. “Seeding the suiUSDe Vault with $10 million is how we move that infrastructure into active use. By pairing a native stablecoin with a professionally curated, permissionless vault on Ember Protocol, we aim to put institutional capital to work on-chain, help form durable liquidity and sustainable yield on Sui, and create another value-creative mechanism for our ecosystem.”

“We’re seeing strong demand for crypto-native products that combine automation, transparency, and composability without requiring users to give up custody,” said Ibra Barbery, Co-Founder of Ember Protocol. “Vaults have emerged as the most effective way to deliver that experience, and partnering with SUIG allows us to bring institutional-grade curation into a fully permissionless, on-chain product that builds on the same ecosystem and technical lineage that helped Bluefin scale its stack of trading products on Sui.”

The vault launch reflects increasing demand for stablecoin-based yield opportunities on Sui and underscores SUI Group’s strategy of pairing native asset issuance with direct capital deployment to accelerate ecosystem growth.
