SparkLend Sees Over $1B in Deposits Since Kelp Exploit as Aave TVL Plunges

0

Aave TVL has dropped by $10B since the Kelp attackers used the protocol to borrow $190 million in WETH, depositing unbacked rsETH.

DeFi’s lending landscape is being reshuffled in real time as capital flees Aave in the wake of the Kelp bridge exploit, and a notable chunk of appears to be landing on SparkLend.

Spark’s stablecoin lending protocol SparkLend has seen over $1.4 billion in deposits flow into it in the past few days since the $290 million Kelp bridge exploit on Saturday, April 18, which has continued to rock DeFi since.

Total value locked on SparkLend surged from around $1.89 billion to $3.3 billion as of today, April 22, per DefiLlama data.

Meanwhile, Aave — now the second-largest protocol in DeFi by TLV, and where the Kelp hackers’ faked funds were deposited — has seen its TVL plunge by $10 billion over the same time frame, from above $26 billion to just over $16 billion today.

Per DefiLlama data, Morpho has seen the second-largest outflows in USD aftr Aave.

Active loans on SparkLend have climbed by roughly $500 million over the same period, suggesting the inflows aren’t just parked deposits but fresh borrowing demand.

The April 18 Kelp exploit saw the attacker deposit unbacked rsETH into Aave as collateral and borrowed about $190 million in real wrapped ETH (WETH) against it, leaving the protocol with between $124 million and $230 million in bad debt, depending on how Kelp ultimately allocates losses from the exploit.

Aave has partially unfrozen WETH markets and received indicative commitments from ecosystem participants to help cover shortfalls, as The Defiant reported yesterday.

In the latest Kelp-related update from Aave, the protocol’s founder and CEO Stani Kulechov wrote on X today, “every bit of my energy right now is focused on the outcome for Aave users and the protocol.”

The question isn’t whether privacy. It’s what sort of privacy

0

Blockchains were built as public networks in the best tradition of open-source technology. But their future is private. And that future is arriving faster than most people realize.

This month, Tempo — the Stripe-backed payment blockchain that raised $500 million at a $5 billion valuation, with Visa, Mastercard, Paradigm, and UBS among its backers — published a detailed architectural proposal for private enterprise stablecoin transactions. Tempo is not a scrappy privacy-native project. It is arguably the most institutionally credentialed blockchain launch in years, built by people who deeply understand what banks, payment processors, and enterprises actually need. When a network with that pedigree makes privacy a launch-week priority, it isn’t a signal. It’s a verdict.

The question of whether or not institutional chains will be private has been settled. What remains is the harder one: what kind of privacy are we actually building?

The problem with public chains

Bitcoin solved a problem that had stumped computer scientists and bankers for decades: how to transfer value between strangers without a trusted intermediary. Ethereum took blockchains further, offering programmable value alongside value transfer — smart contracts that could encode agreements, automate settlement, and eliminate entire categories of middlemen. Then came stablecoins, which married programmability to the stability of the dollar, and from there, the migration of real-world assets to onchain protocols began.

Each wave has brought added institutional interest, capital, and ambition. And now, as regulatory clarity emerges, institutions are ready to deploy resources onchain.

But there’s one thing holding them back — a fundamental flaw that becomes more consequential the larger the numbers get.

Everything is visible. Every wallet. Every balance. Every transaction, in real time, is readable by anyone with a browser. In financial markets, this is not a feature. It is an existential problem. Imagine if every hedge fund’s positions, every corporate treasury’s holdings, every pension fund’s rebalancing trade appeared on a public screen the moment it was executed. Sophisticated counterparties would front-run. Competitors would map your strategy. Criminals would identify targets. The financial system as it exists today would seize up overnight.

Blockchains have been asking institutions to accept exactly that. Tempo’s announcement on April 16 is the clearest possible signal that institutions have finally said: no.

Architecture is destiny

Here is where the conversation gets more consequential — and more nuanced.

Tempo’s solution is Zones: private parallel blockchains connected to the main network. Within a Zone, participants transact privately. The public sees only cryptographic proofs of validity, not underlying data. Compliance controls travel with the token automatically. Assets remain interoperable with Tempo Mainnet. For enterprises running payroll, treasury operations, or settlement workflows, it is a thoughtful and practical design.

But Tempo’s privacy model is operator-visible. The Zone operator — an enterprise or infrastructure provider — sees all transactions within its Zone. The public sees nothing. The operator sees everything. For many regulated institutions, this is acceptable, and may even be required. But it means privacy is contingent on trusting an intermediary. You have moved the visibility problem; you have not eliminated it.

This is not a criticism of Tempo. It is a description of a genuine architectural choice — one with real consequences for anyone thinking carefully about risk.

Zero-knowledge cryptography offers a different path. ZK proofs allow a party to prove that a transaction is valid without revealing the underlying data. A new generation of ZK-native blockchains builds this privacy-preserving functionality into the execution layer itself. Accounts execute transactions locally, with the chain storing only a cryptographic commitment. Nothing sensitive ever touches a public ledger. Transaction history is not browsable. And crucially, no operator has a god’s-eye view — privacy is enforced at the base layer, not delegated to an intermediary.

If Bitcoin gave us trustless transfer and Ethereum gave us programmable trust, ZK-native blockchains offer verifiable privacy: the ability to prove that everything happened correctly without revealing what actually happened.

Compliance without full transparency

The obvious objection is regulatory. Privacy and compliance have long been framed as incompatible — oil and water. That framing is becoming obsolete.

Regulatory compliance does not require that everyone can see your transactions. It requires that the right parties, under the right conditions, can verify that your transactions were legitimate. That is a meaningful distinction, and it is one that ZK cryptography is uniquely positioned to enforce. Selective, programmable disclosure — revealing what regulators need to see, nothing more — is not a workaround. It is a more precise implementation of what compliance actually demands.

Tempo’s model handles this at the operator level. ZK-native approaches handle it at the cryptographic level. Both satisfy the compliance requirement. But they distribute trust very differently.

The question that matters

The financial industry knows it needs to move onchain. It now knows — Tempo’s announcement makes this undeniable — that it cannot do so on fully public infrastructure. The era of public-by-default blockchains as the assumed standard for institutional finance is ending.

What comes next depends on a choice the industry is only beginning to make clearly: privacy through trusted operators, or privacy through cryptographic guarantees that require no trust at all.

Both are legitimate answers. But they are not equivalent. The privacy model you choose determines your risk surface, your compliance posture, and your exposure to the failure modes of the intermediaries you depend on. Architecture is not a technical detail to be resolved later. It is the decision that determines everything else.

The question for the industry is not whether privacy. That debate is over.

The question is what sort of privacy — and who, if anyone, you are willing to trust with the view.

Accenture Showcases Humanoid Robot Warehouse Pilot

0

Accenture used Germany’s Hannover Messe 2026 tech show to illustrate how humanoid robots can now contribute significantly in real-world working environments.

The Ireland-based tech consulting company is showcasing the results of a pilot it conducted in a warehouse in tandem with Vodafone Procure & Connect and SAP, which it says proves how physical AI can make operations more efficient and safer, in the process shaping new business models.

The pilot was conducted at a Vodafone facility in Duisburg, Germany, where humanoid robots were deployed alongside existing systems. The bots are powered by Accenture’s Robot Brain system, which enabled them to engage with human operators using voice, gestures and text, and they were issued inspection tasks by SAP’s Extended Warehouse Management system, which they executed autonomously.

The robots conducted several specific jobs successfully, including detecting misplaced or damaged products; assessing pallet stacking and weight distribution; and highlighting unused space.

The bots also patrolled aisles to seek out potential hazards and identify misaligned pallets, while reporting into the SAP system to enable immediate, informed decision making among their human counterparts.

To prepare for the trial, the robots were trained in digital twins of the warehouse. These were built on Accenture’s Physical AI Orchestrator, which uses Nvidia Omniverse and Metropolis libraries to enable the bots to learn a selection of new skills using imitation and reinforcement learning, and to avoid being restricted to a single repetitive function.

Now, the plan is for Vodafone to use feedback from the pilot to accelerate the rollout of bots in its plants.

Christian Souche, lead for advanced robotics and physical AI at Accenture, claimed the pilot had been a success.

“Humanoid robots can reduce worker injuries and other warehouse safety incidents and lower overtime costs and the dependency on temporary labor,” he said in a statement. “Equally important, Vodafone Procure & Connect will gather valuable data and insights on robot deployment and performance as a basis for a future humanoid workforce solutions business.”

“[This] is a great example of how holistic deployment of humanoid robots — from simulation and training to warehouse deployment and integration with SAP data — creates a closed loop with transactional systems,” Prasad Satyavolu, Accenture’s global lead for manufacturing, operations and physical AI,” said in a statement.

Humanoid bots are gradually becoming a more common sight in manufacturing facilities, notably in the auto industry, where BMW has used them in South Carolina and Leipzig, Germany, and China’s Xiaomi has introduced them in Beijing.

Uzbekistan Launches Crypto Mining Zone in Karakalpakstan

0

Uzbekistan has created a special crypto mining zone across Karakalpakstan under a presidential resolution signed on Friday, opening a supervised framework that lets approved mining companies sell mined digital assets on foreign platforms while keeping the proceeds inside the country’s banking system.

A presidential decree effective Monday creates the “Besqala Mining Valley,” a special mining zone across the Republic of Karakalpakstan, where registered legal entities can carry out crypto mining, use a mix of power sources and apply for resident status through a new directorate under the republic’s Council of Ministers.

The framework gives miners in the zone the right to sell crypto assets obtained through mining on national crypto exchanges or foreign platforms, including through direct contracts, and to exchange them for other liquid crypto assets. Still, the opening comes with strict controls over how mining revenues move through the financial system, and proceeds from those sales must be transferred to bank accounts in Uzbekistan.

Tax breaks aim to lure miners

The decree also provides for a tax exemption through Jan. 1, 2035, while requiring them to pay a monthly fee equal to 1% of income from mining activity to the zone’s directorate. The resolution separately instructs officials to submit draft amendments to Uzbekistan’s tax code within two months.

The new decree adds to Uzbekistan’s recent use of special-zone incentives in Karakalpakstan to attract investment into a region that a 2025 United Nations Development Programme report described as having high poverty rates and limited industrial development.

The new framework also adjusts Uzbekistan’s earlier approach to crypto mining. In 2023, Uzbekistan’s National Agency for Perspective Projects (NAPP) issued a decree on licensing crypto mining operations, requiring firms to only use solar power to mine digital assets. 

The new decree allows a wider mix of power sources within the zone, including renewable, hydrogen and grid electricity, with higher tariffs applied for grid usage.

Uzbekistan expands special-zone strategy to draw investment

The move also fits a broader investment strategy in Karakalpakstan. According to a Reuters report in November 2025, the government had established a separate tax-free zone for artificial intelligence and data center projects, offering discounted electricity and tax exemptions to draw foreign investors. 

Under the initiative, foreign firms investing $100 million or more get full tax and duty exemptions until 2040. According to the report, Uzbekistan expects to attract over $1 billion in foreign investment by 2030 from the AI special zone project.
