Odaily News, Coinbase stated on the X platform that the financial layer emerging around AI agents is called agentic finance, namely AiFi, covering agent transactions and agent commerce. AI agents can research information, make decisions, and execute actions on behalf of individuals and businesses, while also needing to perform fundamental financial activities such as making payments, receiving funds, storing value, and transferring money. Coinbase stated that it is building tools for AI agents to enable them to continuously execute financial operations within preset goals, permissions, limits, and security boundaries.Coinbase stated that Coinbase Advisor, Coinbase for Agents, x402, and Coinbase Business have formed the AiFi infrastructure. Coinbase Advisor is an SEC-registered investment advisor integrated into the app for Coinbase One users, providing portfolio analysis and guidance through a chat interface. Coinbase for Agents connects tools such as Claude, ChatGPT, and Cursor to Coinbase accounts via MCP, allowing users to set operating conditions and security boundaries for agents, as well as create separate sandbox accounts for agent use.Coinbase stated that x402 is an open payment standard initiated by Coinbase and now managed by an independent foundation, supporting AI agents in paying fees to other agents, applications, and services. To date, x402 has processed over 205 million transactions with a volume of $53 million, covering 200,000 sellers, with Coinbase facilitating 67% of this activity. Individual payments can be used for API calls, datasets, research materials, or computing resources.Coinbase stated that Coinbase Business supports enterprises in natively receiving USDC payments from AI agents, while Coinbiz helps merchants sell services and content to software without relying on card credentials, manual invoicing, or payment processes designed around human customers. Eligible businesses can earn a floating 3.35% reward on idle USDC balances. USDC currently accounts for 99% of on-chain agent commerce transactions, x402 accounts for 97% of agent finance protocol usage, and the related activities run on Base.
Odaily News: Uniswap founder Hayden said in a post on X that he cannot ignore the theory of correlation trading pairs when observing various things, and noticed that the second-largest Uniswap pool on Base is the Jito staked SOL/BTC trading pair, which aligns with the logic of correlation trading pairs.In an article titled "Correlation Trading Pairs: How AMMs Win the Biggest Markets," Hayden stated that AMMs have the potential to become the core engine of all financial markets, and tokenization will make markets programmable, changing market types, market makers, and the assets being traded.He said Uniswap has been operating autonomously since its launch in 2018, with cumulative trading volume exceeding $4.6 trillion, and has helped increase the proportion of decentralized exchanges relative to centralized spot trading volume from less than 1% to over 20%. As AMMs have developed, their liquidity has gradually formed a structure of correlation trading pairs.He pointed out that AMMs initially achieved product-market fit in the long-tail asset market, and then stablecoin trading pairs developed. Due to the lower capital costs of passive strategies, the demand for professional market making in stablecoin trading pairs has been squeezed.Hayden said traditional financial markets are dominated by market-making firms that integrate capital, trading strategies, execution technology, settlement, and distribution into a single vertical business. Citadel Securities handles approximately 25% of US stock trading volume, with net trading revenue reaching $12.2 billion last year and trading capital of approximately $21 billion.He believes blockchain can unbundle the different components of traditional market-making businesses: code handles execution, shared services provide custody and settlement, and open-source software replaces proprietary infrastructure. The scarce factor of capital in AMMs is capital itself, and participants who can hold inventory at lower costs gain an advantage.Hayden said liquidity providers face lower inventory risk when holding assets with similar price movements, and liquidity will deepen as a result. Ethereum ecosystem assets typically trade against ETH, Solana ecosystem assets typically trade against SOL, stablecoins trade in pairs with each other, and a few high-liquidity trading pairs are responsible for connecting different asset clusters.He noted that once tokenized assets share the same settlement layer, any asset can trade directly against any other asset. For example, NVIDIA/USD can become NVIDIA/SPY and connect to the dollar through SPY/USD; oil companies can trade against oil ETFs or tokenized oil, and private credit can trade against tokenized US Treasury funds.Hayden said traditional market makers typically pursue delta neutrality, reducing risk by denominating in USD and hedging non-USD exposure, which increases market-making costs. A market structure consisting of low-volatility correlation trading pairs and a few high-
Odaily News, The Sandbox has released a post-mortem report on the August 22 vulnerability incident. The report shows that attackers exploited vulnerabilities in contracts related to cross-chain configurations on Base and BNB Smart Chain (BSC), stealing 14,742,341.84 SAND from the Ethereum treasury, accounting for approximately 0.5% of the maximum supply, with an estimated economic impact of approximately $1.4968 million, of which about $987,000 was actually retained by the attackers. The Ethereum mainnet and Polygon network were not affected. Until further notice, please do not purchase or send SAND on Base or BNB Smart Chain. Contracts deployed on Base and BNB Smart Chain have been permanently deactivated and will not be reopened. The Sandbox stated that the team has reported the attacker's wallet address to blockchain analysis firms TRM Labs and Chainalysis, and has communicated directly with relevant exchanges. The Sandbox also announced a compensation plan, which will compensate wallets that legitimately held cross-chain SAND on Base or BSC prior to the incident at a 1:1 ratio in Ethereum SAND. Compensation funds will come from The Sandbox treasury, with no new tokens issued. The claim process will open within the next two weeks and remain open for two weeks.
Odaily News: As of August, cumulative top-ups on USDC- and USDT-linked stablecoin cards have reached $13.8 billion, an increase of nearly $10 billion over the past 12 months. Stablecoin cards are shifting USDC and USDT from trading balances toward everyday consumer use cases.USDC currently leads in tracked card spending, while USDT is accelerating its catch-up. The two follow different adoption paths: USDC benefits more from fintech integrations and payment infrastructure, whereas USDT is more active across exchanges, remittances, and emerging markets.On-chain settlement also reflects a multi-chain distribution, with Base leading at approximately $1.2 billion, followed by Solana at $635 million, Polygon at $544 million, and Optimism at $509 million. Networks such as Arbitrum, Scroll, Ethereum, and Stellar are also carrying significant activity.Stablecoin cards still rely on traditional payment networks like Visa and Mastercard, shifting the competitive focus toward custody, FX costs, cashback, and capital efficiency. Meanwhile, Circle has renewed its USDC partnership with Coinbase under the original terms, excluding any dividend arrangements. (Bitcoin.com News)

Odaily News: Lisk founder Max Kordek announced that Lisk will pivot to a treasury operations platform for enterprise finance teams, offering treasury management services such as accounts, payments, and approvals, while gradually winding down its original blockchain ecosystem. The new platform targets enterprises operating across entities and jurisdictions that use both fiat and stablecoins. Early access is now available for qualified companies, supporting unified management of bank and stablecoin accounts, bank transfers, stablecoin payments and receivables, and permission-based payment approvals. Future plans include corporate cards, non-custodial treasury management, and payroll integrations.Lisk Chain will shut down on October 31, 2026. Lisk has partnered with the Celo team to provide a migration path for on-chain DApps, developers, and projects to move to the Celo network.Lisk also proposed a plan to gradually dissolve the Lisk DAO, including burning 100 million LSK from the DAO treasury, reducing total supply from 400 million to 300 million; removing staking penalties and allowing holders to flexibly unstake, while gradually shutting down DAO governance infrastructure.Lisk stated that LSK will transform into a "loyalty token" for the new platform, where enterprises can earn rewards by using Lisk's treasury operations platform and referring other businesses, and may also use LSK to pay platform fees in the future. LSK will primarily operate on Ethereum and Base going forward. Users who still hold LSK on Lisk Chain must complete the migration to Ethereum before October 31.
Odaily News: THORChain announced the launch of version 3.20, adding native cross-chain swap support for Monero (XMR) and Zcash (ZEC).

Coinbase has launched a Chainlink-based tokenized stock data feed on the Layer 2 network Base, providing developers with real-time market data and order book information.
: Coinbase announced that its tokenized stocks have been natively launched on the Base chain, built on the B20 standard, with the underlying stocks actually held on a 1:1 basis by regulated custodian Alpaca through a bankruptcy-remote structure. Token holders directly own the corresponding stock ownership. Non-US users in globally compliant jurisdictions only need a wallet and an internet connection to gain US equity exposure without a brokerage account or waiting for settlement, and can trade in a 7×24 AMM pool. The first batch supports companies such as Apple and Nvidia. Tokenized stocks can be freely held, transferred, and traded, with no whitelisted wallets or platform lock-ups. Users can use tokenized Nvidia stock as collateral to borrow on Aave, or deposit Apple stock into a decentralized exchange to earn yield. Dividends and stock splits are handled through an on-chain multiplier mechanism. Ecosystem projects such as Aerodrome and Aave have publicly supported the B20 standard. Coinbase stated that more tokenized stocks will be listed in the coming weeks, and it will continue to bring other real-world assets on-chain.
Coinbase launched a tokenized cash stock service on the Layer 2 network Base, allowing users to trade tokens of publicly listed companies backed by actual shares.
Monitoring by PPP Prediction Market Tool shows that on Polymarket, the probability of "Trump picking Margo Martin as the next White House press secretary" briefly rose to 15% before falling back to 9%, up 5% over 24 hours.When asked this week at Joint Base Andrews in Maryland about who would succeed White House press secretary Leavitt, Trump suddenly asked reporters: "What about Margo, what do you all think of her?" He also jokingly turned the question back to the reporters on site, saying, "I don't know (who it will be), maybe it's you."Karoline Leavitt will leave office at the end of August, making "who will succeed Leavitt" a recent focus of U.S. media attention. Margo Martin currently serves as Special Assistant to the President and Communications Advisor, primarily responsible for sharing information about presidential activities via social media.Join the PPP Signal Push Community to stay one step ahead and seize the initiative.
The Sandbox has officially confirmed and fully secured the recent SAND cross-chain bridge vulnerability affecting the Base and BNB Smart Chain (BSC) networks. Attackers exploited the flaw to mint uncollateralized SAND tokens across both networks, but the impact remains limited, accounting for less than 0.01% of the total SAND supply. SAND on Ethereum and Polygon, along with user wallets, remain unaffected. The Sandbox has since disabled cross-chain functionality on both networks. SAND on Base and BSC has been isolated and is temporarily non-transferable and non-redeemable. The official team advises users to avoid buying, selling, or trading SAND on the aforementioned networks.
Odaily News: According to Coinbase's official website, Coinbase has updated its asset listing roadmap, adding Cluster Protocol (CP), Basecat (BASECAT), DebtReliefBot (DRB), Dolphin (POD), and Grass (GRASS).Among them, CP, BASECAT, DRB, and POD are assets on the Base chain, while GRASS is a Solana network asset. Coinbase stated that being added to the roadmap does not mean trading has officially opened; trading will only commence once the assets meet conditions such as market-making support and technical infrastructure requirements.
Odaily News: Coinbase announced on the X platform that Bitcoin is not the only asset on the move. Through the Coinbase app, users can discover and trade Base and Solana tokens shortly after they go live on-chain, with related content available under the "Launches" tab.
Odaily News: Brian Armstrong posted on X platform stating that another feature for AI agents has been launched. The first use case is Travala, where users can use common large language models to book over 2 million properties on Base using USDC. He expressed excitement to see more enterprises building on this foundation with AWS AgentCore and opening their services to the newest and fastest-growing consumer segment.
According to Decrypt, Coinbase announced the official launch of perpetual futures trading in the Base App via Hyperliquid integration. Eligible users can access up to 50x leverage across over 290 perpetual contract markets, including BTC, ETH, tokenized stocks, and commodities.

: Base announced the launch of the Batches 004 accelerator program, which will select 10 startups over an 8-week program, with each receiving $100,000 in investment funded by the Base Ecosystem Fund. Applications close on September 9, and the program will hold Demo Day in New York in November. This round is aimed at pre-seed startups focused on trading, payments, funding, and AI agents, covering products that use stablecoins to support agent shopping, trading, and payments, as well as lending, e-commerce, and decentralized AI infrastructure. Teams may support multiple blockchains but must have Base as their primary network. Selected teams will receive dedicated advisors, weekly support, and exposure assistance within the Base ecosystem, and will present their projects to investors at Demo Day. Coinbase launched Agentic Wallets on Base in February and Coinbase for Agents in June, which respectively enable AI agents to hold USDC and pay via the x402 protocol, and to directly connect to user accounts.

Odaily News: Cryptocurrency exchange Coinbase's x402 payment protocol has processed approximately 14 million AI agent transfers over the past 30 days, with the Base network handling 7.3 million transfers and the Polygon network processing 5.6 million. USDC covers nearly all of these transfers. x402 utilizes the HTTP 402 "Payment Required" mechanism, enabling software to automatically request and complete payments. Coinbase has expanded its related payment services to the Base, Solana, and Polygon networks, supporting USDC as the settlement asset. In July, Coinbase launched Coinbase Business, allowing enterprises to directly receive USDC payments from AI agents, with support for payment collection, reconciliation, and withdrawals. Coinbase has described agent payments as one of its "high-conviction bets." (Bitcoin.com News)
Odaily News: Sheldon Lee, founder of cryptocurrency exchange BitMart, stated that a post on X claiming users were unable to withdraw funds and that some employees had not received their July salaries is a "fabricated rumor," adding that the exchange's Chinese-language account had been hacked. Critics, including users and on-chain investigator ZachXBT, have demanded that BitMart resume withdrawals or undergo an independent third-party audit. BitMart is gradually winding down operations, with the final trading day set for August 26. Troubled investment firm Echo Base said it had proposed a funded restructuring plan to BitMart but received no response. The firm warned that resolving a large volume of customer claims may require proceedings through the courts. (CoinDesk)
Odaily News: Coinbase has announced that it will stop supporting USDC deposits and withdrawals on the Noble network as of August 17. USDC deposits and withdrawals on other supported networks, including Ethereum, Base, Solana, Arbitrum, Optimism, and Polygon, remain unaffected. Coinbase reminds users not to transfer funds to its Noble network USDC deposit address after August 17, as such funds may be irretrievable.
