According to official announcements, OKX’s World Cup prediction campaign has introduced a branded sponsorship prize pool mechanism, with more branded prize pools to be launched subsequently to jointly build the ecosystem.
: HyperLiquid has announced an upgrade to the AQAv2 mechanism. The system will use on-chain automated trading to maintain a dynamic 1:9 balance of USDC between two core addresses in each HyperEVM block, corresponding to the contract execution layer and the treasury reserve layer, respectively.According to the mechanism design, this ratio is used for functional stratification between "high-frequency trading and liquidation liquidity" and "long-term reserves and yield pools," aiming to enhance system stability and isolate trading risks.On the technical side, the balancing process is executed automatically by the system without manual intervention. Circle is responsible for the technical deployment, while Coinbase undertakes the treasury deployment and management.Regarding the yield mechanism, AQAv2 stipulates that stablecoin issuers must distribute approximately 90% of their cost-adjusted reserve earnings generated within the Hyperliquid ecosystem to the protocol. Settlement occurs on a 30-day cumulative cycle, and the earnings will be automatically transferred to the Assistance Fund on the 8th day after the cycle ends.Additionally, the mechanism includes a transition period arrangement:1. Start of yield accrual: August 26;2. First yield payment: October 3.The market believes this design marks the evolution of stablecoins from traditional custody structures toward an on-chain infrastructure model characterized by "protocolized capital stratification + automated yield distribution."
: According to official sources, the OKX 2026 World Cup Prediction Event will introduce a project partner mechanism, with some matches co-branded and built by collaborating projects.It is reported that the OKX World Cup Prediction Event has officially launched. Users can claim and use free points to predict the champion, Golden Boot winner, and individual match results. The platform will distribute the BTC prize pool based on the points leaderboard. This event is the first proprietary market built on OKX's previously released open protocol, Exchange OS, and will operate until the conclusion of the 2026 World Cup.
XRP Ledger developers have submitted a draft amendment titled "AMM Swappable Curves," planning to introduce three types of switchable curves for XRPL's native automated market maker: constant product, concentrated liquidity, and StableSwap, with a programmable Smart AMM to follow.This upgrade aims to allow liquidity providers to choose a more suitable pricing curve based on asset type, thereby improving capital efficiency. Concentrated liquidity is suitable for trading pairs where most transactions are concentrated within a specific price range, while StableSwap is better suited for assets with near 1:1 exchange rates, such as stablecoins or pegged assets. Existing AMM pools will continue to use the current constant product model and do not require migration.This proposal is seen as a crucial step for XRPL to bridge its DeFi infrastructure gap. Currently, there are over $3 billion in tokenized real-world assets on the XRPL chain, including the recent tokenized U.S. Treasury redemption pilot conducted by Ripple and JPMorgan. However, for these assets to be traded, lent, or generate yields more efficiently, a more mature DeFi liquidity infrastructure is still needed.However, the proposal is still in the draft stage. It will need to go through the XRPL amendment voting process, which could take several months, and its eventual approval remains uncertain. (Coindesk)
According to an official announcement from Optimism, the OP mainnet today initiates its first-ever adjustment to transaction ordering rules. For several years prior, the sequencer employed only a “highest-priority gas fee first” mechanism; it now introduces a new staking-based priority ordering option. This four-week experiment (concluding on June 23) was approved earlier this month by the Optimism Governance body and is optional for users. To participate, users must stake at least 100,000 OP tokens in the PolicyEngineStaking contract. The experiment proceeds in two phases: - Phase 1 (Week 1): Transactions are ordered using a FIFO (first-in, first-out) rule; staking amounts exceeding the minimum threshold do not affect priority. - Phase 2 (Weeks 2–4): A priority gas multiplier mechanism is introduced, weighted by staking duration—longer staking periods yield higher priority. For users not participating in the experiment, transaction ordering remains unchanged, and the PGA mechanism continues operating as usual.
Binance Wallet announced on X platform that it has optimized the Meme Rank mechanism. The new ranking logic will no longer focus solely on market hype, but will place greater emphasis on real user participation.According to the official statement, the updated ranking will pay more attention to metrics such as the number of token holding addresses and transaction activity, aiming to more accurately reflect user participation and help users discover trending Meme tokens more quickly.
Lighter officially announced on X that the "escape mechanism" verification conducted by third-party auditor L2BEAT has been completed. This means that even if the sequencer on the L2 layer malfunctions, users can permissionlessly withdraw funds from Lighter's L2 back to Ethereum, making Lighter the industry's first L2 Perp DEX to achieve this functionality.
Aster has announced on the X platform the launch of a new Listing Vote mechanism, enabling a permissionless token listing process. According to the rules, any validator staking at least 20 million ASTER tokens on the Aster Chain can submit a proposal to list a new asset. The proposal then enters an on-chain vote, with the outcome determined by the staked ASTER weight.The first round of proposals was submitted by UTechStables, involving BTC/U and ETH/U perpetual contract trading pairs. This round of voting will continue until 06:00 UTC on May 22.
following the Kelp security incident, Tether's asset interoperability protocol USDT0 has disclosed details of its protocol security architecture. It stated that the system currently utilizes a proprietary DVN (Decentralized Verification Network) with message veto authority, and requires 3 independent validators, operating on different codebases, to reach a 3/3 consensus before cross-chain messages can be settled. The current verification nodes include the USDT0 proprietary DVN, LayerZero, and Canary, with future plans to expand to 4/4 and 5/5 verification mechanisms.USDT0 also stated that all multi-signature transactions must undergo multiple reviews by internal teams, external security teams, and auditing firms before signatures are submitted. The relevant contracts have been audited by firms such as Guardian and OpenZeppelin, and a $6 million bug bounty program has been launched on Immunefi.
LayerZero Labs posted on platform X, stating that the internal RPC used by LayerZero Labs had been attacked by the Lazarus Group over the past three weeks, compromising the true source of its DVN (Decentralized Verifier Network). Meanwhile, external RPC providers experienced DDoS attacks. The incident affected 0.14% of applications and approximately 0.36% of asset value. LayerZero Labs stated that assets are currently secure, and over $9 billion in funds have been bridged through the protocol since April 19.In response to the security risk, LayerZero Labs has ceased providing services for its DVN in a 1/1 configuration. Default configurations for all pathways will migrate to a multi-DVN model of at least 3/3 or 5/5 signatures. Additionally, regarding an incident from three years ago where a multi-sig holder mistakenly used a hardware wallet for personal transactions, LayerZero Labs has removed that signer and replaced the wallet, while developing a custom OneSig multi-sig system. LayerZero Labs advises developers to lock configurations to avoid reliance on default settings and plans to launch an asset management platform, Console, to enhance security monitoring.
Drift Protocol released an explanation of its redemption mechanism, stating that users may redeem at any time after the redemption window opens. However, early redemptions will be fulfilled at the current pool’s proportional share, resulting in a recovery value lower than the full claim amount. Conversely, holders who delay redemption may receive a higher recovery price as the pool’s size grows. The protocol emphasizes that this mechanism aims to balance liquidity with the distribution of returns to long-term holders.
According to an official announcement by Pump.fun, the platform has completed the burning of all previously repurchased $PUMP tokens, amounting to approximately $370 million—roughly 36% of the circulating supply. The burn was executed via two on-chain transactions at 20:52 UTC. Simultaneously, Pump.fun has launched a programmable buyback-and-burn mechanism, allocating 50% of its net revenue over the next year toward publicly purchasing $PUMP on the open market and immediately burning 100% of the acquired tokens. This mechanism is enforced via an immutable smart contract covering revenue streams from Pump.fun’s three core product lines: the bonding curve, PumpSwap, and Terminal. Its execution comprises four steps: fee collection, aggregation into an intermediate wallet, buyback, and burn—all of which can be tracked in real time at fees.pump.fun. The remaining 50% of revenue will fund operational expenses and ecosystem development, including team expansion, strategic investments, and marketing initiatives. Pump.fun stated that this move aims to address community concerns regarding the token’s long-term value and the transparency of the buyback mechanism, with the overarching goal of continuously reducing the circulating supply.
U.S. SEC Chairman Paul Atkins delivered a speech marking his first anniversary in office at the Economic Club of Washington, D.C. The SEC is advancing reforms to its digital asset regulatory framework, integrating them into its “A-C-T” strategy—modernizing regulation, clarifying regulatory boundaries, and reshaping the rulemaking system. Regarding crypto assets, the SEC has released a classification framework for crypto tokens, categorizing digital assets into five types—four of which are not considered securities. Atkins stated that the SEC will soon introduce an “Innovation Exemption” mechanism, providing a limited, compliant framework for market participants to conduct tokenized securities transactions on-chain. The SEC has also launched Project Crypto to adapt securities rules and the regulatory system to the growing trend of capital markets moving on-chain. Additionally, last month the SEC signed a Memorandum of Understanding (MOU) with the CFTC to harmonize key definitions, clarify regulatory jurisdictions, and coordinate oversight of shared regulatory matters—including digital assets. Atkins further noted that the U.S.’s prior approach to crypto asset regulation had driven innovation overseas.
Odaily News: Sonic Labs co-founder and Flying Tulip founder Andre Cronje posted on platform X, stating that his team is continuing to investigate the L0/rsETH incident. Preliminary reports indicate that approximately $200 million worth of rsETH was stolen, possibly due to a private key leak or configuration error. The related assets were subsequently deposited into Aave as collateral to borrow ETH (due to insufficient rsETH liquidity).Andre Cronje pointed out that the affected positions are technically still overcollateralized. However, if bad debt occurs, Aave's token mechanism and Safety Module will serve as the first line of defense to absorb the risk. Nevertheless, Aave has no mechanism to subsidize user losses, as doing so could trigger a bank run. Currently, Aave holds approximately $7 billion in ETH with an outstanding borrowing amount of around $100 million, so the overall impact of this incident is limited. Furthermore, prioritizing user liquidity, Flying Tulip has withdrawn all its ETH from Aave to its fund management wrapper contract. This action was taken because Aave's available liquidity had fallen below its set minimum threshold.
According to Crowdfund Insider, Circle has launched a new solution for high-frequency cross-chain USDC payments. Developers can leverage the Cross-Chain Transfer Protocol (CCTP) to enable local fulfillment providers to front-pay on the recipient’s designated chain, with the platform subsequently performing batch cross-chain settlement. This model reduces operational overhead associated with individual cross-chain transfers and is suitable for platforms processing large volumes of payments daily. Compared to the traditional CCTP process—which requires individual USDC burn-and-mint operations per transfer—the new solution supports batch settlement, reducing the number of burns on the source chain and eliminating the need for signature infrastructure on the destination chain. Circle also demonstrated the workflow using the Arc Testnet and Ethereum Sepolia.
According to an official website announcement, Anthropic has introduced identity verification for certain use cases of Claude to prevent abuse, enforce its usage policies, and fulfill legal obligations. This process is powered by Persona, requiring users to submit a government-issued photo ID and possibly undergo real-time selfie verification. Anthropic states that verification data is used solely for identity confirmation—not for model training, marketing, or advertising. If verification fails, users may retry multiple times within the process or submit a form to request human assistance. Accounts may be suspended in cases of repeated violations of usage policies or terms of service, registration from unsupported regions, or use by individuals under 18 years of age.
According to CoinDesk, the U.S. Department of the Treasury announced it will extend its cybersecurity threat information-sharing service—which was previously available only to traditional financial institutions—to cryptocurrency firms. Eligible crypto companies may apply to join the program through the Treasury’s Office of Cybersecurity and Critical Infrastructure Protection and receive timely, actionable cybersecurity threat intelligence at no cost. Luke Pettit, Assistant Secretary for Financial Institutions at the Treasury Department, stated that this move aims to foster a safer and more responsible digital asset ecosystem. The policy responds to related recommendations outlined in a prior report issued by the President’s Working Group on Digital Asset Markets.
