B2 Wallets associated with stablecoin payment company Triple-A were stolen more than US$9.7 million on the Fourth Chain
According to on-chain analysts, multiple wallets associated with stablecoin payment company Triple-A were stolen on the TRON, Ethereum, Polygon and Arbitrum networks, with a total loss of more than US$9.7 million. These assets were subsequently transferred to the Ethereum network.
On-chain analyst Specter tracked these multi-chain outflows and confirmed that the affected wallets were related to Triple-A. Stolen assets were transferred through cross-chain bridges and eventually gathered into an Ethereum address that started with 0x01F8 and ended with 53b1, totaling approximately 5227 ETH. Funds flowed out of wallets on the four networks and were eventually collected at the address.
Currently, issues such as the specific role of the affected wallet, the ownership of the stolen balance, and whether merchant settlement funds are involved have not yet been confirmed. There is no technical analysis to determine whether the transfer originated from a leak of the private key, theft of the signature certificate, or other vulnerability in the Triple-A wallet infrastructure.
Triple-A has not confirmed this loss
As of the publication of this article, Triple-A has not issued a safety announcement nor provided any explanation for the changes in wallet funds. The company has also not announced a suspension of payment, withdrawal or settlement services.
The Singapore-based company provides Infrastructure services that help companies collect and make payments using stablecoins and fiat currencies. Its platform handles currency exchange and settlement, and merchants do not need to directly manage crypto assets.
Triple-A is a major payment institution regulated by the Monetary Authority of Singapore and received full MiCA authorization for digital asset services from the European Union last month. In addition, the company received approval in principle from the Dubai Virtual Assets Authority (VARA) on broker services on July 15.
The company has not said whether the affected addresses are used for fund management, payment processing, customer deposits or internal liquidity operations.
This media once contacted Triple-A to seek confirmation of the changes in wallet funds, the source of the vulnerability and whether there was customer risk exposure, but as of press time, the company had not responded.
The theft continues this week's wave of crypto asset losses
Prior to the Triple-A incident, three attacks involving cross-chain bridges and project control wallets were disclosed earlier this week. AFX Trade's Arbitrum Bridge suffered unauthorized withdrawals, verifier thresholds and dispute windows were breached, and lost 24.15 million USDC units. The attacker bridged the funds to Ethereum and exchanged them for approximately 12467 ETH.
Subsequently, the Verus Ethereum Bridge was subjected to a malicious import attack that resulted in a loss of approximately US$7.54 million, which resulted in the release of assets without matching Verus network deposits. In addition, 8.59 million B2 tokens worth approximately US$3.86 million were stolen and the related assets were sold on BNB Chain.
As of press time, Triple-A has not confirmed the wallet levels affected, nor has it issued customer guidance or disclosed any recovery processes.
