CertiK published an analysis stating that the Solana ecosystem protocol DeFiTuna was attacked on July 16, with losses of approximately 569,601 USDC. The attacker first created an extremely low-liquidity TUNA/USDC pool and swapped borrowed USDC into the pool via Jupiter routing. Since only a minimal amount of TUNA was ultimately obtained, the protocol experienced rounding down during the position asset value calculation, causing the total assets to be recorded as 0, thereby incorrectly passing the health and solvency checks.

global payment giant Visa is accelerating its stablecoin infrastructure efforts by launching the Visa Stablecoin Platform, which helps banks and fintech companies integrate stablecoin payment capabilities into their existing payment and treasury management systems. It is reported that the platform aims to provide stablecoin service support to approximately 15,000 financial institutions and over 200 million merchants within Visa's network, enabling enterprises to use USD stablecoins for settlement, capital flow, and financial management within the traditional payment network.Visa currently processes approximately $15 trillion in payment transactions annually and has already processed tens of billions of dollars in stablecoin settlement volume. The company hopes to further expand the application scope of stablecoins through this new platform. Initially, the Visa Stablecoin Platform will support the new stablecoin OUSD, launched by the Open Standard alliance, while continuing to be compatible with stablecoins already supported by Visa, including USDC issued by Circle and USDG issued by Paxos. Visa believes that stablecoins are becoming an important part of the future financial infrastructure, with advantages including:Instant Settlement: Transactions no longer rely on traditional banking clearing cycles;Low-Cost Transfers: Reducing payment costs based on blockchain networks;Transparency and Traceability: On-chain transaction records provide higher verifiability.Visa has been consistently building its footprint in the stablecoin space. In 2020, Visa became the first global payment network to support USDC settlement; in 2025, the company launched a stablecoin settlement plan to further promote the entry of stablecoins into the mainstream payment system.Meanwhile, Visa's competitors are also accelerating their entry into the stablecoin market. Mastercard recently launched a stablecoin settlement solution and partnered with companies such as MoonPay and Paxos; American Express has also participated in the ecosystem development related to Open Standard.As traditional payment giants increasingly adopt stablecoins, they are transitioning from a payment tool within the crypto industry into a vital component of the global financial infrastructure.

Court documents reveal that Circle accused Heka of leveraging large-scale arbitrage operations to buy discounted USDC and redeem cash from Circle during the 2023 Silicon Valley Bank (SVB) crisis, suspecting that the relevant funds ultimately flowed to Tether to help it expand its USDT market share.
