Linera has announced the conclusion of the LNRA community round subscription period, during which 617 participants from 69 countries subscribed a total of $848,000 USDC. The funds will be returned to participants' wallets via the original channels, and a follow-up announcement will be released after the refund period concludes.
Odaily News: Circle announced that its Cross-Chain Transfer Protocol (CCTP) now supports a prepaid fee feature for fast transfers. Previously, protocol fees were deducted directly from the USDC transfer amount on the destination chain. With this update, developers can pre-quote and collect fees via native gas tokens on the source chain or USDC before the transfer is executed, simplifying fee handling for cross-chain transfers and ensuring users receive the expected amount of USDC.According to Circle, the prepaid fee mechanism primarily improves fee predictability in cross-chain applications. Users no longer face reduced actual settlement amounts caused by additional deductions on the destination chain. Meanwhile, the CCTP Quote API can uniformly calculate fees across different supported chains and consolidate Fast Transfer and Forwarding fees into a single quote, eliminating the need for developers to build separate systems to calculate multiple protocol fees. Additionally, fees can be paid directly using source chain native tokens without reducing or impacting the actual USDC balance being transferred.
According to the post-incident report released by Tectonic, the Cronos blockchain lending protocol Tectonic suffered an oracle manipulation attack at 12:49 UTC on August 30, 2026. By repeatedly borrowing and re-collateralizing TONIC tokens 98 times within a single transaction, the attacker drove up the TONIC collateral price by approximately 195 times. Leveraging this artificially inflated value, they subsequently extracted assets with a nominal value of $120.4 million from nine lending markets, spanning USDC, USDT, WBTC, WETH, and other assets. The attacker then bridged the stablecoins to Ethereum and converted them to ETH, while selling the remaining assets for CRO on the Cronos chain before withdrawing them. Approximately $9.19 million in total successfully escaped before the network halt. At 14:32 UTC, Cronos validators emergency-paused the network, rolling back the on-chain state to pre-attack conditions and restoring assets still held on Cronos. Currently, Tectonic's supply and borrowing functions remain suspended, while withdrawal and repayment capabilities continue normally. Tracing efforts for the stolen funds are being coordinated by blockchain forensics firms, law enforcement agencies, and stablecoin issuers, with freeze requests already filed with the relevant issuers.
Odaily News: Brazil's cryptocurrency market recorded a trading volume of 505.5 billion reais in 2025, approximately $98.7 billion, representing a more than fivefold increase from 94.9 billion reais in 2020. Corporate-related transactions totaled 497 billion reais, accounting for 98.3% of the total tracked by Brazil's Federal Revenue Service, with individual investors accounting for the remainder.Itaú, Brazil's largest bank by assets under management, now offers 15 crypto assets through its investment app, including Bitcoin, Ethereum, and the USD-pegged stablecoin USDC. Fintech company Nubank lists 28 crypto assets, while Banco do Brasil has seen trading volume exceed 11 million reais since opening direct trading in Bitcoin and Ethereum in January.Filings with the Central Bank of Brazil through March 2026 show that Brazilian banks hold no proprietary virtual asset positions, but may custody and process crypto assets on behalf of clients. Since 2025, Itaú, Bradesco, Santander, Banco do Brasil, and Nubank have all expanded their crypto asset service offerings.Brazil passed the Virtual Asset Legal Framework in 2022 and issued three regulatory resolutions in November 2025, requiring institutions providing crypto asset trading, custody, or transfer services to obtain licenses, meet minimum capital requirements, and maintain segregated client accounts, with a compliance deadline of October 30, 2026. Banco Safra issued the USD-pegged stablecoin Safra Dólar in September 2025, with the bank providing self-custody. (Decrypt)
Odaily News: The decentralized lending protocol Secured Finance's lending market was attacked on September 5, resulting in a loss of approximately $104,000. The root cause was that collateral was priced based on the average execution price of the order book for the current block, allowing attackers to influence the price through self-trading, causing fraudulent lending positions to be counted as valid collateral. The attacker initially deployed the contract but did not execute immediately, then used flash loans and self-trading to inflate the price and withdraw USDC. The original attacking wallet was rolled back due to insufficient gas fees; approximately 48 seconds later, the general-purpose sandwich bot coffeebabe took about 0.9 WBTC, worth approximately $72,000, and transferred about 28.8 ETH of it to the ultra sound money builder, keeping only about $29 for itself. Subsequently, another bot took part of the USDC.
Odaily News: Bitcoin fork asset BTCB2 hit an all-time high of $1,799 on September 5. Over the past 4 hours, its price has fluctuated between 750 and 1,000 USDC; the Neoxa USDC market recorded a 24-hour trading volume of approximately $1 million.BTCB2 originated from a chain split that occurred on August 8, 2026, at block height 961,632. The network subsequently changed its proof-of-work algorithm to Blake2 and reduced block size, and it can now be mined using Blake2-compatible ASIC miners.Neoxa Exchange and Nonkyc.io have listed BTCB2, with the former offering BTC, USDC, and USDT trading pairs, and the latter offering a USDT trading pair. Both platforms have limited liquidity, and CoinMarketCap and CoinGecko have not yet listed the asset.Based on a BTCB2 price of $1,000, its fully diluted valuation stands at approximately $20.9 billion. Since UTXOs need to be split from Bitcoin first, transactions may otherwise be vulnerable to replay attacks; the network's hash rate has risen by 30.41% over the past 7 days, reaching approximately 5.1 PH/s.

Odaily News, Circle has published a statement on the cirBTC reserve mechanism, stating that each cirBTC is backed 1:1 by one native BTC and can be redeemed for native BTC at a 1:1 ratio. The corresponding BTC is held by Circle-affiliated entities and custodied by Circle National Trust, which is regulated by the Office of the Comptroller of the Currency (OCC). The reserve assets are segregated from Circle's corporate assets and are used solely to protect the interests of cirBTC holders. cirBTC is currently live on Ethereum and will receive native support once the Arc mainnet launches, with future expansion to more blockchains. Circle also provides on-chain reserve verification through a public BTC reserve address and the Chainlink Proof of Reserve mechanism, allowing market participants to compare the scale of reserved BTC against the circulating supply of cirBTC across all supported chains.
Odaily News – Coinbase Derivatives and Coinbase Financial Markets, subsidiaries of cryptocurrency exchange Coinbase, respectively submitted Form 1-N and Form BD-N to the U.S. Securities and Exchange Commission (SEC) on September 1, with plans to launch single-stock perpetual contracts in the United States.Coinbase Chief Policy Officer Faryar Shirzad stated that the relevant products still require approval from the U.S. Commodity Futures Trading Commission (CFTC) in the next step. The two filings pertain to registration as a security futures exchange and a limited-purpose security futures broker, respectively.Since March 20, Coinbase has offered non-U.S. users 10x perpetual contracts on stocks such as Apple, Nvidia, and Tesla, settled in USDC and supporting 24-hour round-the-clock trading. U.S. users were previously explicitly excluded from this product. (Bitcoin.com News)
Circle CEO Jeremy Allaire stated that over 1% of CRCL's shares are held as tokenized stocks, with a value exceeding $280 million, surpassing any other publicly traded company globally. He also posed the question of "what year will the tipping point occur?", implying that the scale of tokenized stock holdings could continue to expand in the future.
Odaily News: Circle CEO Jeremy Allaire posted on X: "Over 1% of CRCL shares are held in tokenized stock form, corresponding to a scale of over $280 million, the highest among all publicly listed companies globally. In which year will the 'flip' (Odaily Note: hinting at tokenized stock share surpassing traditional securities share) arrive?"Previously, AMC CEO and Robinhood CEO clashed over the form, legitimacy, and legality of stock tokenization. Circle CEO's move may subtly signal his stance in favor of stock tokenization reform.

Odaily News Uniswap founder Hayden said on X that correlated trading pairs are emerging. The top five tokenized SPY trading pairs by volume are "bridge" pairs connecting other common base pairs, which then primarily link to highly correlated tokenized stocks. These markets are global, programmable, low-cost, and operate 24/7.Uniswap founder Hayden said on X:.I've been working at the frontier of DeFi for 9 years. It's a fascinating field with infinite depth and the potential to transform capital markets.I've always believed AMMs hold immense potential, but for the past decade, one question has persisted: Can this novel market structure truly become the core engine for all financial markets?After years of evolution and development, the path for AMMs to achieve global dominance is becoming increasingly clear. To explain this, we need to start in 1976.Tokenization Changes Market Makers.Index funds celebrated their 50th anniversary this month. When Jack Bogle launched the index fund in 1976, he hoped to raise $150 million but ultimately raised only $11.3 million. Competitors called it "Bogle's Folly," posting posters claiming index funds were un-American. They argued that a fund making no decisions couldn't possibly beat professionals paid to make decisions. Today, the majority of US fund assets are allocated to passive investment vehicles.I've been thinking about this recently because tokenization's "folly moment" is ending. The SEC has approved NASDAQ and the NYSE to trade tokenized stocks. DTCC, which handles virtually all US securities settlement, also conducted a live pilot of tokenized trades in July. Nearly all related activity is described the same way: treating tokenization as an infrastructure upgrade.The same markets, faster, cheaper, and always open. These statements are all true, but I believe the infrastructure upgrade framework obscures a larger change. Tokenization makes markets programmable, changing how markets exist, who makes markets, and what is traded.In 2018, I created Uniswap, an automated market maker protocol. Anyone can deposit two assets into a shared liquidity pool and earn fees from every trade, while prices adjust along a curve as users buy and sell. Uniswap has operated autonomously since its launch, processing over $4.6 trillion in cumulative volume and increasing DEX spot volume share from under 1% to over 20%.As AMMs like Uniswap continue to evolve, their liquidity has formed a pattern most financial markets haven't noticed yet: correlated trading pairs.The Easiest Place to Find Success.To succeed everywhere, you must first succeed somewhere. AMMs found product-market fit in long-tail markets because most assets previously couldn't attract professional market makers' attention. On Uniswap, anyone can create a market with a single transaction, and issuers and early supporters can become the first liquidity providers.Then came stablecoin pairs. Take USDC/USDT, for example. A good passive strategy can approach optimal l

As reported by Caixin, Han Xinyi, CEO of Ant Group and Chairman of Alipay, presented systematic insights on the global exploration paths for AI payments at the China Payment Clearing Forum. He stated that AI payments have basically coalesced into four exploration paths: The first category comprises payment technology and infrastructure platforms represented by Stripe. The second category consists of cryptocurrency enterprises such as Circle and Coinbase, which primarily rely on stablecoins and their wallet ecosystems. Using cryptocurrencies as payment instruments, they directly enable automated machine-to-machine payment scenarios. The third category features traditional payment networks represented by the two major card organizations (Visa and Mastercard). The fourth category comprises AI platform companies such as Google and OpenAI.

Odaily News, Avici announced that its card partner Rain discovered today a vulnerability in an old Solana card contract used by Avici and a few other projects. The relevant contract has now been upgraded across all projects, and no further unauthorized activity has been detected. This incident only affected the standalone Solana contract used to hold post-deposit card balances; users' Avici wallets and card balances are isolated from each other, and funds in Solana and EVM self-custody wallets are safe and unaffected. Upon review, a total of 1,685 users were affected, with combined card balances of approximately $500,900. Avici has committed to fully refunding card balances to all affected users and has filed a report with the FBI's Internet Crime Complaint Center (IC3). Previously reported, Avici, a crypto banking project, saw its native token AVICI allegedly suffer a hacker attack, with losses of approximately $1.02 million. The attacker transferred 10,000 SOL stolen from the project to another wallet, converted it into approximately $1.02 million USDC, and then swapped the funds into approximately 418 ETH via cross-chain operations.
