On April 13, blockchain interoperability protocol Hyperbridge disclosed details of a prior DOT exploit incident that resulted in ~$237,000 in losses. The vulnerability stemmed from missing input validation in the HandlerV1 contract’s `VerifyProof()` function—specifically, it failed to validate that `leaf_index < leafCount`, allowing the attacker to forge a Merkle proof. Using this flaw, the attacker gained admin access to the bridged DOT token contract on Ethereum, then minted 10 billion bridged DOT (over 2,800 times the legitimate circulating supply of ~356,000) and cashed out via a decentralized exchange (DEX). Hyperbridge stated it is collaborating with security partners to trace the funds, and cross-chain functionality will remain suspended until the investigation concludes.

April 13: An article in the American Bankers Association (ABA) Banking Journal on April 13 notes that experts—including the ABA’s Chief Economist—argue the White House Council of Economic Advisers (CEA)’s recent payment stablecoin research report raises misleading questions for policymakers. The CEA report focuses on *how a ban on payment stablecoin issuance would impact bank lending*, concluding the ban would boost bank lending by just ~$1.2 billion with minimal overall effect. But the ABA contends the real policy concern is not the consequences of a “ban,” but the risks of allowing **yield-bearing** payment stablecoins: - **Accelerated deposit outflows**: Yield incentives would drive households and businesses to shift funds from bank deposits (especially at community banks) to stablecoins—with significant impact if the market grows to $1–$2 trillion. ABA analysis shows Iowa alone could see $4.4 billion–$8.7 billion in reduced loans. - **Community bank harm**: Deposit outflows

On April 13, Fortune reported that Foundry—Bitcoin mining pool giant—has officially launched a mining pool for privacy coin Zcash, a move seen as a major endorsement of the crypto. Foundry CEO Mike Colyer noted the Zcash pool launch comes as large institutions show growing interest in so-called "privacy coins." The pool has already signed on several institutional clients, with its computing power now making up nearly one-third of Zcash’s total network hashrate. Zcash currently ranks as the 15th-largest cryptocurrency by market cap, with a valuation of roughly $6.3 billion. Launched in 2016, it uses zero-knowledge proof technology to enable transaction privacy. Unlike competitor Monero, Zcash’s architecture supports selective disclosure—making it more regulatory-compliant and thus more appealing to big institutions like banks.
