The new cryptocurrency bank and non-custodial financial application Tria officially announced the launch of Season 3 activities, introducing a brand new framework for earning points and unlocking rewards for users. Users can earn Tria points through card spending, futures trading, referring friends, and first-time product interactions. Accumulating points to reach specific thresholds will unlock blind boxes ranging from entry-level to legendary and even hidden infinite levels, and the unlocking process will not consume existing points. All blind boxes will be opened at the end of each month starting from August 31, with rewards including cash back, travel points, ecosystem rewards, and exclusive Tria equity lottery qualifications for higher tiers.In addition, this season has simultaneously upgraded the referral and cash back system. Referral levels will strictly promote between bronze, silver, and gold based on the number of active users invited; the credit card cash back mechanism has clarified the monthly limit, and spending beyond the limit can still earn cash back at the base rate. The platform is currently offering a limited-time free virtual card service. The official revealed that Tria plans to gradually launch new functional modules during Season 3, including Tria Travel (travel and real-life experiences), trading competitions, trader VIP badges, and fiat currency withdrawal and recharge.

XRP Ledger developers submitted a draft amendment called "AMM Swappable Curves," which plans to introduce three types of swappable curves for the XRPL native automated market maker: constant product, concentrated liquidity, and StableSwap, with a programmable Smart AMM to be added later. This upgrade aims to allow liquidity providers to choose more suitable pricing curves based on asset types, thereby improving capital efficiency.Concentrated liquidity is suitable for trading pairs where most transactions are concentrated within a specific price range, while StableSwap is more appropriate for assets that are close to a 1:1 exchange, such as stablecoins or pegged assets. Existing AMM pools will continue to use the current constant product model and will not require migration. This proposal is seen as an important step in addressing the shortcomings of the DeFi infrastructure on XRPL.Currently, there are over $3 billion in tokenized real-world assets on the XRPL chain, including a recent pilot for tokenized U.S. Treasury redemptions completed by Ripple and JPMorgan. However, to enable these assets to trade, lend, or generate yield more efficiently, a more mature DeFi liquidity infrastructure is still needed. Nevertheless, this proposal is still in the draft stage and will need to go through the XRPL amendment voting process, which may take several months, and there is still uncertainty about whether it will ultimately pass.

According to official news from Optimism, the OP mainnet has adjusted its transaction sorting rules for the first time starting today. For many years, the sorter only used the "highest priority Gas fee first" mechanism, and now a new priority sorting option based on staking has been added.This experiment will last for four weeks (until June 23) and was approved by the Optimism governance body earlier this month, allowing users to participate voluntarily. The participation condition is to stake no less than 100,000 OP to the PolicyEngine Staking contract.The experiment will be conducted in two phases: the first phase (Week 1) will use FIFO (first in, first out) sorting, and exceeding the minimum staking amount will not affect priority; the second phase (Weeks 2-4) will change to a priority Gas multiplier mechanism weighted by staking duration, where the longer the staking time, the higher the priority.The transaction sorting rules for users who do not participate in the experiment will remain unchanged, and the PGA mechanism will continue to operate as usual.

According to the official announcement, BitRing, a selected project from the 10th season of the BNB Chain MVB Accelerator, has announced the upcoming launch of its genesis airdrop test. It is reported that the top 10,000 users in this test will share a reward of 1,000,000 BRT tokens.According to the official introduction, BitRing allows users to participate in "fitness mining" using smart wearable devices such as Apple Watch and WHOOP to earn BRT. Currently, the development progress of the protocol has reached 90%, and the BRT Protocol is about to enter the internal testing phase, where participating users can now receive 100 tBRT test tokens.In addition, the official revealed that a live fitness coach recommendation system will be launched soon, an ambassador program recruitment will be opened, and plans to explore building personalized medical AI models based on real health data.

According to Forbes, Hyperliquid's native token HYPE reached a historic high of over $62. The market generally attributes this to the influx of institutional funds brought by the listing of the first U.S. spot ETFs, but analysts point out that the real driver of the price is the protocol's built-in continuous buyback mechanism.

According to CoinDesk, bipartisan lawmakers Steven Horsford, Max Miller, Suzan DelBene, and Mike Carey jointly reintroduced the "Digital Asset Protection, Accountability, Regulatory, Innovation, Taxation, and Revenue Act" (also known as the "Equality Act") this Wednesday. The new version of the bill mainly covers the following points: first, it stipulates that regulated payment stablecoins do not generate gains or losses if the cost basis is not less than 99% of the redemption value; second, it establishes a safe harbor for broker-dealer transactions or taxpayer account transactions; third, it clarifies that "wash sale" rules apply to digital assets; fourth, it requires the IRS to assess the current tax burden of small cryptocurrency transactions and to study the feasibility of establishing a tax exemption for transactions under $200 and the potential risks of abuse.The cryptocurrency industry has long advocated for tax exemptions on small transactions to promote the use of cryptocurrencies in everyday payment scenarios. Lawmaker Horsford stated that tax policy is the foundation of the cryptocurrency regulatory framework, and that current tax laws have not clearly addressed many core issues related to digital assets.

Lighter officially stated on X that it has completed the escape mechanism verification conducted by the third party L2BEAT, which means that even if the sequencer at the L2 level fails, users can withdraw funds from Lighter's L2 back to Ethereum in a permissionless manner. It is the first L2 Perp DEX in the industry to achieve this functionality.

Aave has officially proposed a principal retention charitable donation layer, allowing users to continuously donate the generated income to charity while retaining control and liquidity of the principal.The proposal is currently undergoing a temp-check vote in the Aave governance forum. Its core aim is to address three major pain points of traditional charitable models: donors must permanently give up the principal, the funding flow of charitable organizations is unstable, and there is a lack of transparency in the use of funds.According to the proposal, users can deposit assets into yield-generating infrastructures like Aave, direct the earned income to donations, and withdraw the principal at any time.

According to Bloomberg, Iran has begun to launch a Bitcoin-based shipping insurance arrangement for the Strait of Hormuz to address the current high-risk navigation environment in the strait.Recently, Iran has introduced a maritime insurance platform called "Hormuz Safe," which provides digital insurance services for vessels passing through the Strait of Hormuz and allows payments in cryptocurrencies, including Bitcoin.Against the backdrop of escalating U.S.-Iran conflicts and risks in the Strait of Hormuz, the costs of war insurance for ships have surged significantly. Bloomberg previously reported that the insurance costs for some vessels crossing the Strait of Hormuz have now risen to about 5% of the vessel's value.

ZKsync's official announcement stated that following several ZK token governance proposals, the governance service provider ScopeLift has now launched the "ZK Fee Flow System" proposal on the forum. This system is a set of smart contract mechanisms that allow ZKsync Governance to route and allocate protocol revenue and fees through its controllable on-chain mechanisms. ZKsync indicated that the relevant forum post has detailed the contract architecture, operational mechanisms, security measures, and deployment addresses of the system.

After the Kelp security incident, Tether's asset interoperability protocol USDT0 announced details of its protocol security architecture, stating that the current system uses a proprietary DVN (Decentralized Verification Network) and has message veto power, while requiring 3 independent validators to reach a 3/3 consensus based on different codebases before cross-chain messages can be settled.The current validating nodes include USDT0's proprietary DVN, LayerZero, and Canary, with plans to expand to 4/4 and 5/5 verification mechanisms in the future. USDT0 also stated that all multi-signature transactions must undergo multiple reviews by internal teams, external security teams, and auditing institutions before submission for signing. Relevant contracts have been audited by organizations such as Guardian and OpenZeppelin and have launched a $6 million bug bounty program on Immunefi.

Polymarket announced the latest progress on feature updates, including the launch of measures to mitigate latency spam to ensure order placement and cancellation operations, fixing the "insufficient balance/authorization" error, and another core issue affecting limit buy orders is expected to be resolved in the coming days.In addition, Polymarket stated that it has identified and banned multiple clusters of ghost-fill accounts, all of which were created before the deposit wallet system went live. Any account exhibiting ghost-fill behavior will be identified and banned, and the deposit wallet system will also prevent non-compliant accounts from continuing to create new accounts in bulk. More updates will be released in the coming week to address previously outstanding issues.

LayerZero Labs posted on the X platform that the internal RPC used by LayerZero Labs was attacked by the Lazarus Group in the past three weeks, resulting in the compromise of the true source of its DVN (Decentralized Verification Network), while external RPC providers faced DDOS attacks. This incident affected 0.14% of applications and approximately 0.36% of asset value.LayerZero Labs stated that asset security is currently intact, and since April 19, over $9 billion in funds have been completed across chains through the protocol. In response to security risks, LayerZero Labs has stopped providing services for its DVN in a 1/1 configuration, and all default configurations for channels will be migrated to at least a 3/3 or 5/5 multi-DVN mode.Additionally, in response to an incident three years ago where multi-signature holders mistakenly used hardware wallets for personal transactions, LayerZero Labs has removed that signer and changed wallets, while also developing a OneSig custom multi-signature system. LayerZero Labs recommends that developers lock configurations to avoid relying on default settings and plans to launch an asset management platform Console to enhance security monitoring.

According to market news, LayerZero Labs co-founder and CEO Bryan Pellegrino had a heated debate with security researchers today in the ETHSecurity Community Telegram group. The core controversy includes: since LayerZero Labs can immediately upgrade a default library contract without a time limit to forge messages (similar to the case where rsETH was hacked), the LZ OFT, valued at over $3 billion, is recently at risk of being stolen; researcher Banteg pointed out that mainstream projects like Ethena and EtherFi were still using this default library contract weeks ago, and currently, there is still $178 million worth exposed to risk, with these funds coming from projects that are still using the default library.On-chain data shows that LayerZero Labs multi-signature signers participated in non-multi-signature activities such as meme coin trading, DEX exchanges, and cross-chain bridging, which means that the multi-signature keys in the formal environment were connected to websites, increasing phishing risks. Regarding the multi-signature signers of LayerZero using production environment keys for trading activities, Bryan confirmed that the related transactions were completed by members of the multi-signature team, but denied that it was "meme coin trading," explaining it as "testing PEPE on the LZ OFT token standard," and stated that the involved member has been removed. Bryan also suggested that project parties "directly fix configurations" instead of using default configurations to reduce risks. Banteg subsequently tagged a long list of LayerZero users still using the default library contract, pointing out that these projects should migrate to fixed configurations as soon as possible.

Paradigm general partner Dan Robinson proposed the "Proof of Address Control Timestamp" (PACTs) mechanism, aimed at providing a protection path for Bitcoin addresses against potential threats from quantum computing.This solution allows holders to generate address control proofs through BIP-322 and create on-chain commitments using a random salt value, completing time anchoring with OpenTimestamps to establish ownership proof without disclosing wallet information. If quantum-vulnerable addresses are frozen in the future through a soft fork, users can submit STARK zero-knowledge proofs to unlock their assets when spending. This mechanism also provides a potential recovery path for wallets derived from BIP-32, but its implementation still relies on Bitcoin introducing STARK verification capabilities and gaining community consensus.

Researcher Dan Robinson from Paradigm proposed a new scheme called PACT (Verifiable Address Controlled Timestamp), aimed at protecting long-dormant bitcoins, including Satoshi's early addresses, from future quantum computing attacks.This mechanism allows users to prove their control over an address through a timestamp without the need to transfer assets or expose on-chain behavior. Once future quantum attacks occur, assets can be recovered in a quantum-resistant version of the Bitcoin network based on that proof. Compared to mandatory migration schemes (like BIP-361), PACT avoids the privacy exposure issues caused by actively transferring assets, providing long-term holders with a more flexible preemptive protection path.

Curve Finance officially announced that it is introducing a bad debt recovery mechanism based on on-chain market mechanisms, allowing CRV-affected users in certain lending markets with bad debts to choose different recovery strategies: directly selling their claims to exit, continuing to hold and wait for potential recovery, or providing liquidity to earn fees and incentives. The core of this mechanism is to establish a trading pool between crvUSD and the tokens of the affected claims, allowing bad debt claims to be priced in the market and creating liquidity, thereby providing users with an immediate exit channel instead of relying solely on the final liquidation results.It is reported that after the cryptocurrency market crash in October last year, some lending markets under Curve Finance experienced bad debt issues, with various liquidity pools being impacted by severe price fluctuations and liquidity contraction, leading to some deposit users facing withdrawal restrictions and asset losses.Curve stated that the recovery mechanism will not eliminate losses or guarantee recovery, but will gradually reflect risks and recovery expectations through a market-oriented approach. Additionally, if the governance layer distributes rewards through the veCRV incentive mechanism, it will help enhance liquidity depth, improve exit conditions, and strengthen market pricing efficiency.
