The Sandbox has released findings on a recent SAND bridge security incident. It said an attacker exploited a configuration function in the SAND token contract on Base and BNB Chain, where the contract also served as the LayerZero bridge integration, and set themselves as the sole verifier for incoming bridge messages. The attacker then stole about 14.74 million SAND from the Ethereum vault backing the bridge, roughly 0.5% of the fixed 3 billion maximum supply, while the team said it quickly contained the exploit and completed on-chain forensics.

U.S. Sen. Bernie Moreno said negotiations on the CLARITY Act have formally concluded after 11 months, leaving the bill to face a vote in Congress. If passed, the legislation would establish a clearer regulatory framework for digital assets and could open the door to trillions of dollars in institutional capital. Market participants broadly view the move as potentially positive for crypto assets such as XRP.

On Aug. 22, Kiichain was exploited through vulnerabilities in the Cosmos EVM module, with losses of about 148 million KII. The team halted the chain after detecting the attack to prevent further losses, and about 80.70 million KII remains frozen in the attacker’s on-chain address and is recoverable after a restart. Most of the remaining funds were bridged to BNB Chain and sold, while another 3 million KII was sent to KuCoin and a freeze request has been filed. The issue stems from three flaws in a shared Cosmos EVM module that also affected Mantra and TAC the same week, and Kiichain is preparing fixes, an upgrade and restart, plus asset migration and bridge limits.

USDD said it has expanded its Vault to the Ethereum network, allowing users to mint the USDD stablecoin by depositing ETH or WBTC as collateral. The overcollateralized, user-controlled CDP model sets a minimum collateralization ratio of 130% and a stability fee as low as 4%. The move is aimed at improving capital efficiency by letting users unlock liquidity while retaining upside exposure to the underlying assets. It also positions USDD as evolving from a single stablecoin into a multi-chain yield infrastructure with on-chain yield opportunities.

Stacks’ Q2 report says the total number of wallets in its ecosystem has surpassed 1.6 million. It also notes that its Bitcoin-based staking feature has moved into a public testnet phase and is scheduled for an official launch in Q3. The update signals deeper integration between Stacks and the Bitcoin network, laying groundwork for a subsequent mainnet rollout.

Metallicus said it has received FedNow service certification, covering send, receive, liquidity management and Request for Payment (RFP) capabilities. The company said this infrastructure runs alongside the Metallicus blockchain ecosystem, including XPR Network, WebAuth Wallet, digital identity, stablecoins, DeFi and institutional digital-asset infrastructure. The move connects XPR Network to the Federal Reserve’s FedNow instant payments network through Metallicus, creating a compliant pathway for integrating crypto payments with traditional financial infrastructure.

Bitcoin restaking platform BounceBit said it will gradually wind down its proprietary L1 blockchain after a recent exploit. The platform’s core business centers on BTC restaking, and it said the security incident has led to the decision to end operations of the underlying public chain. The team has not disclosed details of the attack or the size of the losses, but the shutdown decision has delivered a major hit to the project’s fundamentals.
