Uniswap protocol surpasses $250M in volume on Robinhood Chain in under a week

The post Ethereum Trader Loss Exploit Exposes DeFi Vulnerability appeared on BitcoinEthereumNews.com. Just after 2 a.m. UTC on July 7, 2026, an Ethereum trader watched $2 million worth of Ether effectively vanish in a single block — not to a hacker, not to a scam, but to a routing vulnerability that silently redirected the swap through a near-empty liquidity pool. The incident is now one of the starkest documented cases of an Ethereum trader loss exploit involving same-block backrun extraction, and it exposes a structural tension at the heart of decentralized finance. Key takeaways An Ethereum trader swapped 1,126.44 ETH (~$2.01 million) and received only 5,776 LIT tokens worth roughly $14,500 — a 99.3% loss. The swap was routed through a low-liquidity AVAIL/WETH pool on Uniswap v3, executing at approximately 120 times the sustainable price for AVAIL. Block builder Titan extracted $1.8 million as a builder reward in the same block via same-block backrun arbitrage. GoPlus Security class

The divergence in USDT and USDC usage highlights evolving stablecoin roles, impacting global payment systems and decentralized finance growth. The post Tether’s USDT dominates payments while Circle’s USDC leads DeFi, Dune data shows appeared first on Crypto Briefing.

The post Dune: USDT Leads Payments, USDC Dominates DeFi appeared on BitcoinEthereumNews.com. The world’s biggest stablecoins are increasingly becoming chain-specific financial products, with Tether’s USDt (USDT) and Circle’s USDC (USDC) serving distinct roles across the crypto ecosystem rather than competing head-on. Dune’s Digital Asset Brief found that USDT overwhelmingly dominates onchain payments. During the first half of 2026, the biggest stablecoin settled about $95 billion in identified commerce payments, compared with $14 billion for second-biggest USDC. It also accounted for roughly 92% of the $48 billion in business-to-business payment volume. On Tron, USDT’s largest network, around 93% of the token’s supply is held in ordinary wallets rather than on exchanges, underscoring its role as a payment and remittance asset. USDC, meanwhile, has established itself as the dominant stablecoin in decentralized finance. USDC on Base processed roughly $2.6 trillion in transfer volume in J

The post Summer.fi reveals months-long preparation behind $6M DeFi exploit appeared on BitcoinEthereumNews.com. Summer.fi has published a detailed post-mortem on the $6.04 million exploit that drained two of its Lazy Summer Protocol USDC vaults. It concludes that the attack was planned months in advance rather than being an opportunistic flash loan exploit. The report says the attacker spent roughly three months accumulating the assets needed to manipulate the protocol. The exploit was executed in a single atomic transaction on July 6.  It also argues that the root cause was an operational issue during the offboarding of an old strategy rather than a flaw in the protocol’s smart contracts. Attack exploited incomplete offboarding process According to the post-mortem, the attacker manipulated the net asset value [NAV] of two USDC vaults. Stale-valued Silo vault tokens were donated into an Ark that had been capped during an offboarding process. However, the Ark remained included in the va
