Ethena Proposes 95% Revenue Buyback as ETH Holds $2,504

ETH sits at $2,504.09, flat over 24 hours (+0.05%) on $13.5 billion in volume while broader crypto markets digested a week of gains ahead of Kevin Warsh's closely watched Jackson Hole debut. Bitcoin briefly tagged $81,455 overnight before retreating below $80,000, and the Coinbase premium flipped positive for the first time since May, a signal that U.S. institutional buyers are back on the bid.

Ethena Moves to Funnel 95% of Revenue Into Token Buybacks

ENA jumped 10% after the Ethena Foundation put a governance proposal to vote that would redirect 95% of net protocol revenue toward buying back ENA tokens currently held by major early investors. The mechanism functions as both a supply reduction and a fee switch, converting protocol earnings into sustained demand for the token. If passed, the buybacks would be funded from Ethena's revenue stream rather than its treasury, a distinction that matters for sustainability. The vote signals a broader trend among DeFi protocols experimenting with value accrual models that go beyond simple staking rewards.

Ledger Ethereum App Vulnerability Patched After OneKey Reproduces Exploit

Hardware wallet maker Ledger fixed a transaction replacement vulnerability in its Ethereum app after rival firm OneKey reproduced the attack in a lab environment. The exploit targeted an outdated version of the Ledger Ethereum app, allowing a malicious actor to potentially substitute transaction details after a user had reviewed them on the device screen. No user funds were lost. Ledger addressed the issue in Ethereum app version 1.22.2, and users running current firmware are not affected.

The disclosure follows responsible security research norms, with OneKey coordinating with Ledger before publishing. The episode underscores the importance of keeping hardware wallet firmware current, particularly as transaction replacement attacks grow more sophisticated across EVM chains.

Sandbox Commits to Full Repayment After $700K Bridge Exploit

The Sandbox pledged 1:1 repayment from its treasury after a $700,000 exploit hit its cross-chain bridge affecting SAND holders on Base and BNB Chain. Eligible holders will receive Ethereum-based SAND tokens, with claims expected to open within two weeks. The project is covering losses entirely from its own reserves rather than socializing them across the community, a response that sets a precedent for how metaverse and gaming protocols handle bridge failures. Bridge exploits remain one of the most persistent attack vectors in crypto. The Sandbox incident, while small by historical standards (Ronin: $625 million, Wormhole: $320 million), adds to the long list of bridge security failures that have collectively drained billions from users.

Visa Expands Stablecoin Push Through South Korea's Largest Exchange

Visa signed a partnership with Dunamu, the operator of South Korea's dominant exchange Upbit, to explore stablecoin payments and remittances. The deal puts Open Standard's proposed OUSD stablecoin among several assets under review for integration. Coming on the heels of Visa's separate arrangement with Shinhan Financial, the move represents a deliberate deepening of the payments giant's presence in what has become Asia's most active retail crypto market. The focus on stablecoin-powered remittances and AI-driven commerce suggests Visa sees programmable money infrastructure as a competitive necessity, not an experiment.

Kraken Users Caught in Sanctioned Funds Lockout Wave

Kraken temporarily locked out some users between August 17 and August 24 after a wave of transactions appeared designed to spread sanctioned crypto across accounts, triggering automatic compliance restrictions. The pattern suggested a deliberate attempt to weaponize sanctions screening protocols, forcing account freezes on users who received tainted funds without their knowledge. Kraken has since restored access for affected accounts, but the incident highlights a growing attack surface: compliance systems can be gamed to cause targeted disruption, turning regulatory infrastructure into a denial-of-service vector.

BitGo Absorbs NYDIG's Trading Arm

BitGo completed its acquisition of NYDIG's institutional trading business, adding roughly 30 employees along with derivatives and financing capabilities. The deal expands BitGo's position as a custody-plus-trading platform for institutional clients, a model that competes directly with the prime brokerage offerings from Coinbase, Fireblocks, and others. Consolidation among institutional crypto infrastructure providers has accelerated in 2026, as firms that once specialized in a single vertical (custody, execution, lending) race to offer integrated stacks.

Abu Dhabi Royal Backs Trump-Linked Crypto Bank

A group led by Sheikh Tahnoon bin Zayed Al Nahyan is backing a 49% stake in the holding company behind World Liberty Financial's conditionally approved U.S. trust bank, according to the Wall Street Journal. The deal would give the Abu Dhabi royal family a significant position in a Trump-affiliated crypto banking venture. The arrangement raises questions about foreign ownership thresholds in federally regulated banking entities and adds another layer to the increasingly complex intersection of sovereign capital, U.S. politics, and crypto finance.

Market Snapshot

Bitcoin's Coinbase premium turning positive for the first time since May suggests U.S. spot demand is strengthening, even as BTC failed to hold above $80,000 after its overnight push. Treasury yields are rising on both sides of the Atlantic ahead of Warsh's speech, which could shape expectations around Fed support for Treasury buybacks. The implications for crypto are indirect but real: if Warsh signals hawkishness, risk assets may give back some of this week's 9% BTC rally and 20% SOL surge. If he leaves the door open for accommodation, the current bid likely extends.

Solana's governance drama continues with three disinflation proposals clearing quorum but the most aggressive burn plan trailing below the two-thirds support threshold. The outcome will determine the pace of SOL supply reduction and could set a precedent for how proof-of-stake networks manage monetary policy through on-chain governance.

Magic City Update

The Sandbox bridge exploit and subsequent treasury-funded repayment carry particular relevance for Miami's growing concentration of real-world asset tokenization firms. Homebase, the Miami-based platform tokenizing real estate on Ethereum, operates in a sector where bridge security and cross-chain asset integrity are existential concerns. As tokenized property portfolios grow, any bridge vulnerability that compromises the chain-of-custody for an asset-backed token could undermine the legal enforceability that distinguishes RWA tokenization from speculative DeFi.

Miami also stands to benefit from Visa's stablecoin expansion. The city's role as a gateway between U.S. and Latin American capital flows makes it a natural testing ground for stablecoin-powered remittance infrastructure. Several Miami-based fintechs, including stablecoin infrastructure provider Zero Hash, have positioned themselves to capture this corridor. As payments giants like Visa formalize stablecoin partnerships abroad, the pressure builds for domestic regulatory clarity that would let Miami-based firms scale their existing cross-border payment rails.
