The blockchain gaming platform The Sandbox stated that it will compensate users who held bridged SAND on Base or BNB Smart Chain at a 1:1 ratio before the bridge vulnerability attack, with compensation provided in Ethereum-based SAND from the project treasury, and there will be no token issuance. This attack resulted in the theft of approximately 14.744 million SAND from the Ethereum treasury, valued at about $700,000.The application process is expected to open within two weeks and will last for two weeks; over 72% of the balances held by two centralized exchanges that meet the compensation criteria will be directly compensated to affected customers. The Sandbox indicated that the attacker exploited a configuration vulnerability in the SAND contracts on Base and BNB Chain, becoming the sole validator of bridge messages and minting unbacked tokens. Additionally, over 339 trillion unbacked SAND was minted on the two networks but has been isolated and cannot be cross-chain or exchanged; SAND on Ethereum and Polygon remains unaffected, and the compromised bridge contracts will be permanently disabled.

The Sandbox released an update on the security vulnerability attack incident involving the SAND cross-chain bridge, stating that the attacker modified the verification mechanism to forge cross-chain deposit messages and mint unbacked SAND. This incident resulted in approximately 14.7423 million SAND being withdrawn, valued at about $697,000. Additionally, some uncollateralized SAND was profited through market trading, leading to an overall economic impact of approximately $1.497 million, of which the attacker actually obtained about $987,000.The Sandbox stated that the attack did not affect the supply of SAND on Ethereum and Polygon, with the total amount of SAND on Ethereum remaining unchanged at 3 billion. There were also no super administrator privileges stolen, and the attack stemmed from a vulnerability caused by the combination of the general call function in the token contract and the design of bridge permissions. Currently, the related addresses have been marked, and collaboration has begun with exchanges, security agencies, and the LayerZero team.For affected users, The Sandbox promises to compensate wallets holding legitimate bridged SAND with a 1:1 ratio of SAND on the Ethereum chain based on an on-chain snapshot taken before the attack. The compensation application process is expected to open within two weeks and will last for two weeks.

The Sandbox released an incident analysis report on the vulnerability on August 22. The report shows that attackers exploited vulnerabilities in cross-chain configuration contracts on the Base and BNB Smart Chain (BSC) to steal 14,742,341.84 SAND from the Ethereum treasury, accounting for approximately 0.5% of the maximum supply, with an estimated economic impact of about $1.4968 million, of which approximately $987,000 was actually intercepted by the attackers. The Ethereum mainnet and Polygon network were not affected.Please do not purchase or send SAND on Base or BNB Smart Chain until further notice. The contracts deployed on Base and BNB Smart Chain have been permanently disabled and will not be reopened. The Sandbox stated that the team has reported the attackers' wallet addresses to blockchain analysis companies TRM Labs and Chainalysis and is in direct communication with relevant exchanges.The Sandbox also announced a compensation plan, which will compensate wallets that legally held cross-chain SAND on Base or BSC before the incident at a 1:1 ratio with Ethereum SAND. The compensation funds will come from The Sandbox treasury, and no new tokens will be issued. The application process will open in the next two weeks and will remain open for two weeks.

The metaverse gaming platform The Sandbox confirmed that there is a vulnerability in its cross-chain bridge, allowing attackers to mint uncollateralized SAND on Base and BNB Smart Chain. Blockchain security company PeckShield discovered on August 21 that two addresses had collectively minted approximately 1.49 billion SAND, prompting The Sandbox to shut down the bridging functions for both networks.The Sandbox stated that the affected assets are those bridged on Base and BNB Smart Chain, while SAND on Ethereum and Polygon, user wallet assets, and Ethereum locked assets used to support the tokens remain unaffected. The incident involved a proportion of real collateralized assets that is less than 0.01% of the total supply of SAND. The Sandbox is formulating a compensation plan for the affected liquidity providers and advises users not to trade SAND on Base or BNB Smart Chain until the bridging function is restored.Coinbase plans to delist 10 perpetual futures contracts, including SAND, on August 26, at which time any open positions will be automatically settled.

According to a post by @0xMaxs, Hyperliquid core contributor Xulian is publicly soliciting feedback on the latest testnet template for HIP-4. The template can be accessed via on-chain queries or the testnet API, with each template family identified by an incrementing integer suffix for the latest version. After collecting feedback, validators will review and vote on-chain, and only approved templates will be written to the mainnet for deployers to use; all template instantiations still depend on HIP-4 being enabled on the mainnet.It is reported that the testnet currently has 16 template records (including old versions), with approximately 12 latest templates based on the highest version of each family, covering 7 types of market structures. Candidate types include expiration prices (settled using specified period TWAP), price-triggered markets, range earnings, as well as central bank decisions, sports two-way options, and sports win/draw/loss, etc. The mainnet outcomeTemplates and deployer list are currently still empty, and permissionless templates have not yet been officially opened.HIP-4 is Hyperliquid's permissionless deployment standard for outcome/prediction markets, with the complete process being: community feedback, validator review, on-chain voting, template writing to the mainnet, and market creation by deployers once the switch is enabled.
