Mantle Enters DeFi with Non-Custodial Stablecoin Vault Launch

Mantle, a company that offers real-world asset yield business, has expanded into decentralized finance (DeFi) by launching a non-custodial stablecoin vault on the Fluxion network. The new product follows the success of Mantle's Bybit-based vault, which managed over $200 million in assets.

The DeFi vault allows users to deposit USDC or USDT stablecoins and earn yield through sUSDS, a savings version of Sky's USDS stablecoin, with a target APY of up to 6.5%. Unlike the previous centralized model, this product lets users maintain control of their assets without handing funds to a custodian.

The vault strategy is designed by CIAN and connected to Grove's yield sources, operating without leverage to reduce liquidation risk but still carrying smart-contract and market risks. Mantle's move reflects growing demand for tokenized real-world assets and stablecoin liquidity in DeFi, with its network's total value locked surpassing $1 billion in 2026.
