According to ChainCatcher, Mantle Vault has expanded from CeFi into DeFi and launched a non-custodial yield vault for stablecoin holders with Grove, CIAN and Fluxion. The vault accepts USDC and USDT0 deposits and uses underlying sUSDS strategies to generate institutional floating yield, with a target APY of up to 6.5%. Users can also earn Fluxion Points and incentives tied to 5.14 million GROVE tokens. Mantle said the vault uses a conservative, non-leveraged structure, with CIAN building the strategy, Grove providing the Sky Savings Rate capital base and Fluxion handling liquidity access. Mantle added that the move is meant to give stablecoin holders borderless access to institutional-grade yield within its open financial network.

Castle Labs’ latest on-chain market note tied together four developments now shaping the crypto market: mounting regulatory scrutiny of crypto vault strategies, fast early growth on Robinhood Chain, the sudden rise of TokenWorks’ Fake World Assets on Ethereum, and Mantle’s push deeper into tokenized real-world assets. The sharpest regulatory signal came from SEC Commissioner Hester Peirce, who warned that some crypto vault strategies may raise issues normally associated with portfolio managers or investment advisers, depending on how yield activities are selected and how assets are reallocated. That framing has intensified debate over whether vault managers are operating more like code-driven infrastructure or discretionary asset managers. On the market side, Robinhood Chain has already accumulated more than $800 million in on-chain assets and nearly $500 million in stablecoin market cap, with memecoin pairs accounting for 65.9% of spot DEX volume. On Ethereum, Fake World Assets reached roughly 10% of mainnet gas consumption within seven days of launch. Mantle, marking its third anniversary, ended the second quarter with 155 tokenized stocks, more than $1 billion in DeFi TVL and $955 million in stablecoin market cap, while continuing to build liquidity and execution rails around tokenized RWA products.

Mantle has officially added SKHYx, a tokenized stock tied to SK hynix, marking the fourth tokenized equity listing on the platform in less than a month after SPCXx, USPXx and BSPx. SKHYx is issued by xStocks and is now available for trading on Fluxion. The trading setup uses Fluxion’s hybrid infrastructure: its Atomic RFQ mechanism anchors pricing to live market quotes during regular trading hours, while the AMM execution model keeps trading open after the underlying market closes. Users who trade SKHYx can earn xPoints, the native reward issued by xStocks, and also share an additional 1 million Fluxion Points based on trading volume and liquidity contribution. Mantle said the launch extends the rapid buildout of its tokenized stock lineup and brings another globally significant company onto blockchain rails.

Mantle has officially listed BSPx, the tokenized stock representing Bending Spoons, making it the third tokenized equity launched on the network in less than a month. BSPx is issued by xStocks and is now available for trading on Fluxion, Mantle’s decentralized exchange for these assets. The product follows earlier listings of SPCXx on June 19 and USPXx on June 23, extending Mantle’s push to bring newly listed traditional equities on-chain at a pace closer to public market timelines. According to the announcement, BSPx trading on Fluxion uses a hybrid infrastructure. During regular market hours, Atomic RFQ anchors pricing to live market quotes, while the AMM execution layer is designed to keep trading available after the underlying market closes. Mantle said this structure supports more continuous access to tokenized stocks on-chain. The listing also comes with stacked incentives. Eligible BSPx trades can earn both xPoints, the native rewards system from xStocks, and additional rewards from a 1 million Fluxion Points pool distributed based on trading volume and liquidity contribution. The incentive program applies across the broader xStocks asset lineup, including TSLAx, NVDAx, AAPLx, METAx, GOOGLx, MSTRx, SPCXx, USPXx, and BSPx.
