VanEck said on May 28 it launched VBNB, a U.S. exchange-traded product designed to give direct spot exposure to BNB by holding the token rather than using futures or synthetic structures. The prospectus lists Anchorage Digital Bank as custodian and says staking rewards may be added later, while also flagging Binance-related regulatory sensitivity and a validator set of 21 active validators as key risks.

Bifrost said it has started repaying a 1,000,000 DOT liquidity loan from the Polkadot treasury after the deployment produced 53,185 DOT in returns.

Bifrost is unwinding the DOT-vDOT position, unstaking vDOT, and preparing to send the earned interest back to the treasury.

SoFi says it has introduced its SoFiUSD stablecoin directly inside its banking app, positioning itself as the first U.S. national bank to bring a stablecoin into a consumer banking platform.

Blockaid reported an exploit affecting StakeDAO on Arbitrum in which an attacker allegedly took control of the protocol's deployer private key. The incident involved a manipulated LayerZero cross-chain flow that minted 5,446,744,073,709 vsdCRV tokens before the attacker swapped tokens for ETH across multiple DEX routes and was estimated to have extracted roughly 43.9 ETH (about $91,000).

Optimism has started a four-week trial on OP Mainnet, beginning 26 May, to give eligible OP stakers preferential transaction ordering.

HTX had not issued a public response at the time of writing.

Babylon Labs has submitted a temperature-check proposal to integrate with Aave V4, aiming to let users lock native BTC on Bitcoin and borrow assets via Aave without wrapped BTC, bridges, or custodians. The design uses Taproot-based vault scripts and introduces a non-transferable accounting asset, vaultBTC, to represent BTC locked in Babylon vaults as collateral within approved Aave contracts. Aave founder Stani Kulechov endorsed the idea on X and said Babylon has more than $4bn in BTC staked that could eventually be used as collateral.

The project team had not publicly addressed the allegations at the time of writing.
