Odaily News: After a firmware vulnerability in Coldcard hardware wallets was exploited, approximately 2,100 Bitcoin were stolen, with losses nearing $130 million. On-chain data shows that in the days surrounding the incident, wallets held by long-term holders transferred out approximately 233,000 Bitcoin, valued at around $15 billion. Casa CEO Nick Neuman stated that some of the transferred funds came from Coldcard users migrating to multi-signature wallets, with Ledger and Trezor users also taking similar measures after the event. During the same period, approximately 22,000 Bitcoin were transferred into exchanges. Coinkite has advised users who generated seed phrases using firmware versions 4.0.1 through 4.1.9 to treat their wallets as compromised and immediately migrate to new seed phrases. These versions cover the period from March 2021 to July 2026. (Decrypt)

Odaily News: The cross-chain bridge connecting XRP Ledger and Coreum was attacked on August 9. The attacker exploited a validation logic vulnerability to steal approximately 199,900 XRP, reducing the bridge's asset balance from roughly 200,400 XRP to 493.5 XRP. The attack did not involve private key leaks and did not target the XRP Ledger protocol itself. The attacker forged deposit operations, causing the bridge system to recognize them as legitimate deposits and triggering the bridge wallet on the other end to send real XRP. On-chain data shows that the attacker completed the fund transfer through 94 multi-signature authorization transactions within 97 minutes. These transactions required signatures from 17 of the 28 relay node keys, allowing the attacker to bypass the bridge's validation mechanism. As of August 11, the Coreum cross-chain bridge remains suspended, and the Coreum Development Foundation has not yet released an official incident report. The XRP mainnet and user private keys remain unaffected and secure.
硬件钱包厂商 Ledger 就 BIP-110 分叉发布安全提醒称，BIP-110 是一项未内置重放保护（replay protection）的比特币软分叉方案，如果形成独立链，BTC 持有者可能在新链获得相同数量的对应资产，但两条链初期可能接受相同签名交易。 用户若尝试转移或出售 BIP-110 链上的资产，相关交易可能被“重放”至比特币主链，导致对应 BTC 同时被转出。
Odaily News: The latest software version 3.3.0 of XRP Ledger (XRPL) introduces several upgrade proposals, including Confidential Transfers. This feature is designed for institutional users, supporting encrypted token balances and transfer amounts while preserving the visibility of accounts and token types. It is primarily applied to Multi-Purpose Tokens (MPT) on XRPL, including tokenized financial assets such as funds and bonds. Through cryptographic technologies like zero-knowledge proofs, the network can verify transaction validity without disclosing specific amounts. XRPL currently holds approximately $1.38 billion in on-chain real-world assets (RWA), including about $845.7 million in RLUSD. In addition to RLUSD, there are over $530 million in tokenized assets on XRPL, involving issuers such as Ondo, VERT Capital, Archax, and Societe Generale. XRPL 3.3.0 also includes five proposals—Batch, Sponsor, Permission Delegation, and Dynamic MPT—addressing institutional needs such as batch transactions, fee sponsorship, permission management, and dynamic adjustments to token attributes. The aforementioned upgrades have not yet been officially launched and will only be activated after receiving support from more than 80% of XRPL's trusted validator nodes for two consecutive weeks.
Odaily News: Hardware wallet manufacturer Ledger has stated that the recent Coldcard vulnerability indicates the hardware Bitcoin wallet industry needs to reassess its security model. Ledger CTO Charles Guillemet stated that Ledger devices were not affected, as their recovery phrases are generated by a hardware random number generator built into a certified secure element. Coldcard manufacturer Coinkite disclosed last week that its air-gapped Coldcard Bitcoin hardware wallet contains a vulnerability traceable to firmware versions from March 2021. The vulnerability uses a software fallback mechanism to generate wallet recovery seeds, allowing certain private keys to be guessed, with related losses reaching approximately $130 million. Coinkite released a fixed firmware on Sunday and urged affected users to transfer funds to newly generated wallets. Charles Guillemet stated that open source is different from being audited — the flaw had existed in public code for over five years, and AI is enabling attackers to scan code and identify vulnerabilities at machine speed. Charles Guillemet also said that over the past two years, Ledger has combined AI with security engineers and cryptography experts to review code and identify vulnerabilities. He believes that when evaluating hardware wallets, users should understand how randomness is generated and whether that process has received independent certification.
According to Bitcoin.com, a recent survey report released by Bearingpoint shows that 23% of Swiss adults use cryptocurrency at least occasionally, far higher than 11% in Germany and 18% in Austria. The survey was conducted by YouGov in June 2026 among over 4,000 adults in Germany, Austria, and Switzerland. The report points out that Switzerland's leading advantage stems from its Distributed Ledger Technology Act (DLT Act) officially effective in 2021, which provides a clear legal framework for crypto assets, attracting a large number of enterprises to establish operations, and driving the expansion of the "Crypto Valley" ecosystem to 1,749 blockchain companies. Additionally, 37% of Swiss respondents consider cryptocurrency an asset worth investing in, and 45% support it becoming an international reserve currency, both leading Germany and Austria. In contrast, regarding Germany, although retail adoption rates lag behind, the "meinkrypto" platform under DZ Bank and Dekabank's crypto services for the savings bank network are expected to cover approximately 80 million customers, potentially gradually narrowing the gap with Switzerland.
Ripple announced strategic investments in UK fund technology company ZILO and FCA-regulated tokenized trading platform Licuido, integrating regulated digital transfer agency, asset issuance, and collateral liquidity capabilities into the XRP Ledger. Ripple stated that the relevant infrastructure will support tokenized funds as collateral from the issuance stage and enable atomic settlement via XRPL, while RLUSD can serve as the regulated cash leg in delivery versus payment transactions. The investment amount was not disclosed.
Odaily News: Jazzi Cooper, RippleX Product Lead, announced on X that the next version of XRP Ledger, xrpld 3.3.0, is set to launch next week. Upon release, it will introduce five new features to validators: confidential MPT, batch transactions, delegated permissions, fee sponsorship and reserves, and dynamic MPT. Among these, the amendments for batch transactions and delegated permissions were previously urgently withdrawn after security researchers discovered severe vulnerabilities. She noted that XRP Ledger already has the capacity to support tokenized assets at scale, and this upgrade will further drive the adoption of these assets in global transfers, trading, collateralization, and settlement scenarios.
Sui Foundation and Mysten Labs launched the Bitcoin mortgage protocol Hashi testnet on July 22, allowing BTC to provide collateral support for on-chain lending and credit markets without being wrapped into synthetic tokens or bridged across chains. Hashi keeps Bitcoin on the Bitcoin network, with deposits secured by a 2-of-2 multi-signature mechanism that requires simultaneous signatures from Hashi's multi-party computation validators and an independent Guardian Layer. Loan terms and collateral positions are recorded on-chain, allowing lenders to view the collateral backing. Over 25 institutional partners are testing Hashi's lending and credit applications, including Bitgo, Cumberland, FalconX, Ledger, Blockdaemon, Bullish, as well as Sui ecosystem lending platforms Navi and Scallop. Wave Digital Assets has committed to advancing a three-year Bitcoin yield bond tokenization plan on Sui after the Hashi mainnet launch. Hashi has not yet announced a mainnet launch date. Sui previously unveiled the Hashi development network phase in March, positioning the protocol as a solution to improve capital efficiency for the approximately 1.4 trillion dollar Bitcoin market.

a16z Crypto has released an analysis stating that traditional finance (TradFi) is not merging with decentralized finance (DeFi), but is instead selectively adopting blockchain technologies that meet its own needs. A long-standing narrative within the crypto industry has been that DeFi and TradFi will eventually merge, combining open liquidity with institutional distribution to form a new system superior to traditional finance. However, the reality may be different.The core driver for traditional finance's adoption of blockchain is not the concept of decentralization, but commercial efficiency. As long as blockchain can help institutions reduce costs, improve settlement efficiency, expand distribution channels, and enhance customer relationships, they will adopt the relevant technology. “TradFi is not entering DeFi; it is utilizing the parts of DeFi that fit its own operational models and reshaping these technologies according to institutional requirements.”a16z Crypto stated that a new category of financial infrastructure may emerge in the future—"programmable financial infrastructure" based on a blockchain foundation but optimized for institutional constraints. The blockchain technologies currently being adopted by institutions mainly include:Atomic Settlement: Reduces counterparty risk and decreases tied-up collateral capital;Shared Ledger: Lowers the cost of back-office reconciliation;Programmable Money: Automates interest payments, margin management, and corporate actions;Automated Market Makers (AMM): Being repurposed for on-chain foreign exchange and tokenized asset pricing.
According to The Block, Ledger's security research team Donjon disclosed a security vulnerability in Tangem hardware wallet cards. After obtaining the physical card, attackers can use laser fault injection equipment to bypass recovery state verification in the firmware and reset the password, thereby controlling the wallet and initiating transactions. The research states that this vulnerability affects all Tangem cards currently in circulation, and since the product does not support firmware updates, it cannot be fixed via patches.
According to CoinDesk, Swift announced that its blockchain-based shared ledger platform is ready and will launch real-time transaction testing with 17 major banks. Participating institutions include HSBC, UBS, BNP Paribas, Citi, BNY, and Wells Fargo, among others, covering six continents. The platform aims to enable 24/7 cross-border payments through tokenized deposits, allowing banks to transfer funds for customers during nights and weekends, and providing liquidity support before final settlement is completed in existing payment systems. Swift clearly stated that the ledger system is positioned as a complement to existing payment rails, not a replacement.
Jack McDonald, Senior Vice President of Ripple's stablecoin business, disclosed eight recent developments regarding RLUSD in a post on X on June 29, covering settlement, regional access, on-chain liquidity, cross-border payments, multi-chain support, exchange listings, charity, and the Japanese market. Mastercard has expanded its settlement capabilities to support RLUSD across eight blockchain networks, including the XRP Ledger. Ripple has also expanded RLUSD's availability in Turkey through partnerships with BiLira, Bitexen, and Bitlo, and collaborated with Bitso to enable RLUSD and MXNB to support liquidity and cross-border transactions via the XRP Ledger's Permissioned DEX. RLUSD has also achieved multi-chain support through Wormhole Native Token Transfers and entered the Japanese market via SBI VC Trade after receiving approval from the Japan Financial Services Agency. Additionally, RLUSD has been listed on exchanges such as Gate and Floq, integrated with the cross-chain infrastructure provider Squid Router, and Ripple has joined Water's GetBlue campaign as its exclusive digital asset and payment partner.
According to an announcement by the Hong Kong Monetary Authority, the Financial Services and the Treasury Bureau (FSTB) and the Hong Kong Monetary Authority (HKMA) jointly announced on June 29 that they have completed the first-phase review on promoting the further application of Distributed Ledger Technology (DLT) in Hong Kong's fixed income market. The review results confirmed that Hong Kong's existing legal and regulatory environment is sufficiently flexible to support the issuance of tokenized bonds. The Companies Registry released frequently asked questions on the same day, clarifying that registers of debenture holders maintained using DLT comply with the relevant provisions of the Companies Ordinance. The next phase of the review will commence in the second half of this year, focusing on legal optimization issues such as allowing electronic signatures to execute tokenized bond issuance documents, as well as the "possession" and "transfer" of tokenized fixed income products, to promote the wider application of DLT in the fixed income market and the digital asset sector.
Ripple is advancing the addition of a lending infrastructure layer on the XRP Ledger (XRPL), enabling institutions to raise funds using on-chain tokenized assets as collateral. The protocol will automatically execute loan terms, while credit evaluation and lending decisions remain handled by off-chain institutions.According to disclosures, the proposal is named the XRPL Lending Protocol (corresponding to XLS-65 and XLS-66 standards). It is currently in the technical draft stage and will require approval through validator voting before launching on the mainnet, but developer testing has already been opened on the test network.The protocol’s design splits the lending process into two parts: on-chain management of liquidity pools, interest calculation, repayment execution, and default handling; while borrower credit assessment and loan term setting remain with traditional financial institutions to meet compliance requirements across different jurisdictions.Ripple states that the mechanism is primarily aimed at institutional short-term liquidity needs. For example, in cross-border payment scenarios, temporary financing through stablecoins or collateral assets can be obtained before settlement is completed, thereby improving capital efficiency.Analysts believe that while the plan attempts to introduce a “rule-enforced lending infrastructure” similar to traditional finance while maintaining XRPL's open network attributes, it will still face competition from established on-chain lending protocols such as Aave, Compound, and Maple.
