Mantle Expands Stablecoin Yield Business into DeFi with New Non-Custodial Vault

Mantle has expanded its stablecoin yield business into non-custodial decentralized finance (DeFi) by launching a new vault that lets users deposit USDC or USDT0 directly into a smart contract. The vault, built with Grove infrastructure and CIAN's strategy design, packages positions and transactions so they remain visible onchain without leverage.

The new Mantle stablecoin vault allows users to gain exposure to yield tied to sUSDS, the savings version of Sky’s USDS stablecoin, with a target APY of up to 6.5% plus incentives through Fluxion Points and GROVE tokens. The vault's technical design is deliberately conservative, avoiding leverage entirely.

The move arrives just months after the exchange-based version of Mantle Vault crossed $200 million in assets under management, giving Mantle a track record to lean on as it tests whether DeFi users will follow where CeFi customers already went.
