hot_img In the first half of the year, cryptocurrency TradFi transactions exceeded $1.3 trillion, with the exchange landscape shifting from a unipolar concentration to a multipolar distribution

According to a research report published by RootData Research, the total trading volume of mainstream cryptocurrency exchanges in the TradFi sector surpassed $1.3 trillion in the first half of 2026, nearly a tenfold increase compared to the entire year of 2025, with TradFi derivatives accounting for over 98%, becoming the core engine driving the explosive growth of the sector.The exchange landscape is shifting from "unipolar concentration" to multipolar competition. Binance, while maintaining a leading position in the TradFi sector with a cumulative share of 68.3%, saw its monthly trading volume share decline from 78.8% at the beginning of the year to 58.2% in August. Meanwhile, second-tier exchanges such as OKX, Gate, and Hyperliquid are rapidly expanding, with market shares of 18.2%, 10.7%, and 9.9% respectively in August.In the core submarket of stock derivatives, entering August, Binance still dominated with an average daily trading volume of $14.927 billion; OKX established an advantage in trading costs with the industry's lowest spread of 0.0091%, achieving a comprehensive score tied for second with Gate. Gate has recently shown independent growth, recording four consecutive months of triple-digit month-on-month growth from May to August, and in mid-August, its ±2% weighted depth ranked first in the industry for 11 consecutive trading days. The competitive logic of the TradFi sector may be shifting from a battle for traffic to a competition across comprehensive dimensions such as position size, market depth, trading costs, and variety coverage.

first_img OneKey reproduces the transaction replacement attack targeting the old version of the Ledger Ethereum application

The security team of the open-source wallet provider OneKey successfully replicated the exploitation of a vulnerability in the old version of the Ledger Ethereum application in a laboratory environment. OneKey's founder and CEO Wang Yishi stated that they executed a "transaction replacement attack" on Ledger Ethereum application version 1.22.1 by exploiting a previously patched vulnerability, allowing attackers to overwrite pending transactions while users review legitimate transactions.Ledger responded that exploiting this vulnerability requires controlling the communication between the device and the host, such as through malware, compromised wallet software, or malicious web pages. Ledger has added application layer protections in the Ethereum application version 1.22.2 released on August 13 and fixed the underlying issue in Secure SDK 26.6.1 on August 21. Ledger emphasized that no users were hacked as a result; this was merely a replication of the vulnerability in a laboratory environment.This security test occurred after the Coldcard vulnerability incident. Previously, the Coldcard wallet had a firmware vulnerability that posed security risks to some mnemonic phrase generation, but Ledger stated that its devices were not affected by this vulnerability because recovery phrases are generated by a certified random source built into the device's secure chip. The vulnerability replicated by OneKey is unrelated to mnemonic phrase generation but affects the way transactions are processed during the signing process.

Coinbase launches AiFi financial system: x402 has processed over 205 million transactions

Coinbase stated on the X platform that the financial layer surrounding AI agents is referred to as agent finance, or AiFi, which encompasses agent trading and agent commerce. AI agents can research information, make decisions, and execute operations on behalf of individuals and businesses, and they need to perform basic financial activities such as payments, receipts, value storage, and fund transfers. Coinbase claims that it is building tools for AI agents to continuously execute financial operations within predefined goals, permissions, limitations, and security boundaries.Coinbase indicated 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 like Claude, ChatGPT, and Cursor to Coinbase accounts via MCP, allowing users to set operational conditions and security boundaries for agents, as well as create independent sandbox accounts for agent use.Coinbase stated that x402 is an open payment standard initiated by Coinbase and currently managed by an independent foundation, which supports AI agents in paying fees to other agents, applications, and services. As of now, x402 has processed over 205 million transactions, with a transaction volume of $53 million, covering 200,000 sellers, with Coinbase facilitating 67% of the activities. Single payments can be used for API calls, datasets, research materials, or computing resources.Coinbase indicated that Coinbase Business supports enterprises in natively receiving AI agent payments in USDC, and Coinbiz can help merchants sell services and content to software without relying on credit card credentials, manual invoicing, or payment processes designed with human customers in mind. Eligible businesses can earn a floating reward of 3.35% from idle USDC balances. USDC currently accounts for 99% of on-chain agent commerce transactions, while x402 represents 97% of agent finance protocol usage, with related activities operating on Base.
