On April 22, USDC issuer Circle announced a strategic partnership with Hong Kong licensed digital asset platform OSL Group to expand USDC's trading and payment access in global markets, especially in Hong Kong. The collaboration supports 1:1 USD / USDC instant conversion and capital-efficient settlement. At the same time, Circle launched the Unified Balance Kit, which provides developers with chain-abstracted access to multi-chain USDC balances based on the Circle Gateway protocol, supporting instant cross-chain USDC transfers within 500 milliseconds and significantly improving cross-chain liquidity efficiency.
2. OKX and BitGo Complete OTC Settlement Integration in the U.S.

On April 24, OKX announced that it has completed OTC settlement (OES) integration with crypto custodian BitGo in the U.S. market, offering OKX's U.S. institutional clients a capital-efficient solution where assets are held in custody by BitGo and trading takes place on OKX. BitGo holds a U.S. qualified custodian license, and institutional clients' digital assets can be held in BitGo's regulated accounts while trading on the OKX platform through the OES mechanism, significantly reducing counterparty risk for institutions on centralized exchanges.
3. Chainlink Data Standard Now Available on Amazon AWS Marketplace

On April 25, decentralized oracle network Chainlink announced that its Data Standard has officially launched on Amazon AWS Marketplace. This integration means that millions of developers and hundreds of thousands of enterprise customers on AWS can directly access infrastructure provided by Chainlink, including market data, proof of reserves, cross-chain messaging, and more, to build institutional-grade blockchain applications. Chainlink has previously collaborated extensively with mainstream financial infrastructure providers such as Swift, DTCC, and Euroclear.
4. KelpDAO Cross-Chain Bridge Hacked for $292 Million, LayerZero DVN Configuration Vulnerability in Focus
https://www.jinse.com.cn/news/blockchain/3732178.html
On April 18, an attacker stole 116,500 rsETH, worth approximately $292 million, from the KelpDAO cross-chain bridge within 46 minutes, making it the largest DeFi security incident so far in 2026. The attacker exploited a 1 / 1 DVN configuration vulnerability in the LayerZero cross-chain bridge, forged cross-chain messages to mint uncollateralized rsETH, and then deposited it into protocols such as Aave to borrow real ETH. The incident triggered a chain reaction across DeFi, with multiple protocols suspending functions, the Arbitrum Security Council urgently intervening to recover part of the funds, and KelpDAO and LayerZero disputing responsibility.
5. Litecoin Hit by Zero-Day Consensus Vulnerability DoS Attack, Blockchain Rolled Back and 13 Blocks Rewritten
Around April 25, Litecoin suffered a DoS attack stemming from a zero-day consensus vulnerability. The attacker exploited a vulnerability in the MWEB (Mimblewimble Extension Block) protocol to launch a denial-of-service attack against major mining pools, causing unupdated nodes to accept invalid MWEB transactions and resulting in a reorganization of 13 blocks on the network (about 32 minutes). Subsequent CoinDesk reporting showed that the consensus vulnerability had already been patched through private channels between March 19 and 26, more than four weeks before the attack, but the patch had not been promptly pushed to all mining pools.
Industry Dynamics
1. U.S. SEC Chair Proposes "ACT" Strategy, Crypto Regulation Shifts from Enforcement to Rulemaking
https://www.jinse.com.cn/blockchain/3732068.html
On April 21, U.S. SEC Chair Paul Atkins delivered a keynote speech at the Economic Club of Washington, calling for the establishment of a "clear, consistent, and principle-based" regulatory framework to make the United States a center for digital asset innovation once again. Atkins proposed the "ACT" strategy: advancing regulatory modernization (Advance), clarifying regulatory boundaries (Clarity), and transforming the enforcement mechanism (Transform), while working with other regulatory agencies and Congress to promote the implementation of a digital asset regulatory framework, marking a formal shift in U.S. crypto regulation from "enforcement first" to "rule-guided."
2. U.S. OCC Releases Proposed Rules for the GENIUS Stablecoin Act

On April 21, the U.S. Office of the Comptroller of the Currency (OCC) announced proposed rules for implementing the GENIUS Act, establishing a federal regulatory framework for the U.S. stablecoin industry. The rules cover core provisions such as stablecoin issuer registration requirements, reserve management standards, audit obligations, redemption mechanisms, and anti-money laundering compliance requirements. The OCC stated that the framework will allow the stablecoin industry to develop on a "safe and sound" basis, with the public comment period running until May 1.
3. UK FCA Conducts First Raid on Illegal P2P Crypto Trading Venue

On April 22, the UK Financial Conduct Authority (FCA), together with HM Revenue and Customs and the Organised Crime Department, conducted raids on eight suspected illegal P2P crypto trading locations in London and issued stop-operation notices to the relevant entities. This was the FCA's first coordinated enforcement action of this kind with multiple departments, focusing on activities that may involve money laundering and terrorist financing. The regulator noted that there are currently no P2P crypto dealers registered with the FCA in the UK.
4. Bank of Korea's New Governor Pushes Ahead with CBDC and Deposit Tokens
On April 21, Bank of Korea's newly appointed Governor Shin Hyun-song stated in his inaugural speech that he would actively promote the development of CBDCs and deposit tokens through "Project Hangang," but the entire speech did not mention "stablecoins." This was interpreted as the South Korean central bank's preference to position CBDCs and bank deposit tokens, rather than private stablecoins, as the core of digital payment infrastructure, reflecting the central bank's emphasis on digital payment sovereignty and financial stability.
In-Depth Analysis
1. Ethereum Founder Vitalik Speaks at Hong Kong Web3 Festival: Security and Decentralization Are the Core
https://www.learnblockchain.cn/article/25111
On April 20, Ethereum co-founder Vitalik Buterin delivered a keynote speech at the Hong Kong Web3 Festival 2026, systematically outlining Ethereum's technical roadmap for the next five years. Vitalik positioned Ethereum as a "public bulletin board" and "shared computing layer," clearly stating that Ethereum should not pursue extreme speed, but should instead prioritize security, decentralization, and verifiability. The core of the roadmap includes: short-term scaling (continuing to raise the Gas limit and advancing zkEVM), post-quantum secure signatures (signature schemes based on hashes and lattice cryptography, with vectorization to reduce Gas costs), ePBS (separation of proposer and builder) to enhance censorship resistance, EIP-8141 account abstraction to enable native smart contract wallet support, and AI-assisted formal verification to improve code security. Vitalik emphasized that zkVM is already fast enough to enable real-time virtual machine execution proofs, and that zkVM-based chain verification will begin on a small scale in 2026 and gradually expand through 2028. The overall vision is for Ethereum, as the "world computer," to steadily improve scaling, privacy, and quantum resistance while maintaining long-term robustness.
