Mantle has expanded Mantle Vault from its Bybit-based CeFi product into DeFi through a non-custodial vault available via Fluxion. Users can deposit USDC or USDT0 while retaining control of their assets and access variable yield generated through sUSDS, Sky Protocol’s yield-bearing token. CIAN designed the conservative, non-leveraged strategy, Grove connects deposits to the Sky Savings Rate via Grove Savings and governance-approved strategies, and Fluxion provides the liquidity layer plus Fluxion Points. Mantle is running a dedicated incentive programme of 5.14 million GROVE tokens with materials targeting up to 6.5% APY, though programme terms, duration and rates may vary and incentives are not guaranteed. The earlier Bybit product surpassed $200 million in assets under management. Mantle’s RWA TVL has grown from $22 million to $257 million in a year, with DeFi TVL exceeding $755 million in figures supplied with the launch, while other coverage has cited different TVL readings by date and provider. The vault’s strategy-generated return and separate promotional rewards also come as U.S. lawmakers debate restrictions on stablecoin yield and rewards.
