Co-founder and Chief Operating Officer of the cross-chain trading platform Relay, Jason Maier, stated that the team discovered an issue with the Relay API over the weekend, which exposed pending transaction information before trade execution. MEV seekers exploited the pending routing status to infer on-chain paths and front-run trades before order execution, resulting in worse execution prices for users trading through Relay.This activity occurred from September 12 to September 26, primarily concentrated from September 23 to 26. Seekers profited approximately $136,000 from this, affecting around 5,600 users, with a median impact of $11.88. Relay will pay a $50,000 bounty to Outputlayer for reporting the issue and will automatically compensate affected users without the need for applications; funds will be directly sent to wallets, with a total compensation amount of approximately $312,000.Jason Maier stated that MEV can arise through public mempool exposure, order detail inference, malicious participation in auctions, or data gaps between service providers, and protecting a single link in the transaction path is not sufficient. He mentioned that the team will continue to enhance the execution quality and privacy of the entire transaction path and called on security researchers to report vulnerabilities when discovered.

User gpugene stated during a discussion on computing power trading: Some B300 transaction prices have exceeded 24 dollars per GPU hour, and the price of computing power with a term shorter than 1 year remains above 7 dollars and is still rising. gpugene expressed the hope to use computing power derivatives to guard against the rise in GPU hour prices while retaining the flexibility to adjust rental durations; if inference clouds sell services at fixed prices and their own GPU bills fluctuate, they have effectively taken on the risk of computing power price changes.The article provides an example where a supplier can offer a plan for 2048 B300s, available for rent for 5 years at 4.15 dollars per GPU hour, corresponding to an amount of 372,264,960 dollars. If the client goes live after 12 months and uses this scale from the 13th to the 15th month, the total would be 4,485,120 GPU hours. gpugene calculated that the current premium for a call option with an exercise price of 4.50 dollars is approximately 4.83 million dollars; if changed to a compound option, the current payment would be about 2.70 million dollars, with an additional payment of about 4.49 million dollars upon exercising in the 12th month.gpugene also compared 4000 hypothetical 5-year rental and demand paths. The average cost of annual renewal is 4.72 dollars per hour, with the worst 5% scenario averaging 10.91 dollars; after adding the call option, these figures change to 4.88 dollars and 7.20 dollars, respectively, with the premium included. gpugene believes that the emerging computing power derivatives market may change how neocloud and related participants expand and protect themselves.

Analysis released by a16z crypto on September 23 shows that the total transaction volume of real-world asset perpetual contracts in August 2026 is $11.73 billion, with on-chain platform transaction volume accounting for about $10.1 billion, or 86%; centralized exchange transaction volume is about $16 billion, an increase of 44 times compared to the same period last year.

NYSE American, a subsidiary of the New York Stock Exchange, has been operating since 1908, while Uniswap was launched in 2018; five years ago, Uniswap's monthly transaction volume was only about 2 million transactions.Valente noted that in terms of transaction volume, the next target for Uniswap to catch up with is NYSE Arca, which completed approximately 232 million transactions in August.

According to Crowdfund Insider, SoFi Bank announced that it has used its own stablecoin SoFiUSD for transaction settlement across the entire Mastercard card business network, claiming to be the first national bank in the United States to achieve this model. SoFi previously estimated that after migrating all its debit and credit card operations to stablecoin settlement, the annual transaction volume would exceed $25 billion.SoFi launched SoFiUSD in December 2025 and opened it to users in the SoFi app in May of this year; the two parties announced their partnership in March of this year. RS2 CEO Radi El Haj stated that stablecoin settlement has moved from the previous pilot phase to actual operational phase covering the entire Mastercard network, with related settlements occurring at the underlying level of the existing card payment system, requiring no changes to the current payment methods for consumers and merchants.

CryptoQuant analyst Darkfost stated that a recent paper explored the possibility of implementing privacy transactions on Bitcoin, characterized by the ability to achieve this directly on Bitcoin L1 without the need for a soft fork, making privacy transactions a native feature.Darkfost mentioned that he is not a developer and lacks the relevant technical background, but this idea is quite appealing. He believes it could be an important direction for Bitcoin's evolution according to Satoshi Nakamoto's original vision, while potentially diminishing the appeal of privacy projects like Zcash and Monero.

According to CoinDesk, Barclays, HSBC UK, Lloyds, Monzo, Nationwide, NatWest, and Santander have completed the world's first interbank tokenized pound deposit customer transaction through the UK's tokenized deposit scheme.Among them, Lloyds, NatWest, and Barclays completed two remortgage transactions, with funds automatically released upon completion after being locked; three banks, including HSBC, completed peer-to-peer payments simulating online shopping.The platform was built by Quant, with EY responsible for project management, and Yearn Finance drafting the rules. The project plans to establish a company and create a rulebook, intending to issue three digital bonds that can be traded using tokenized deposits in the first quarter of 2027.

IBM announced that customers of its digital asset management platform IBM Digital Asset Haven can now connect to permissioned blockchain networks, including the blockchain-based shared ledger from Swift. A new beta version of the ISO 20022 message adapter allows financial institutions to initiate tokenized deposit transactions through this ledger using standard payment messages. IBM stated that financial institutions participating in Swift-related programs have tested tokenized deposits on this ledger using Digital Asset Haven. The ledger supports tokenized deposits issued by banks, enabling participating IBM clients to transfer digital assets around the clock, with final settlement still completed through existing systems.Swift first announced this ledger at Sibos 2025, based on a prototype developed in collaboration with Consensys, with over 40 financial institutions involved in its design, 17 of which are participating in the tokenized deposit pilot. Swift currently connects over 12,500 financial institutions across more than 200 markets worldwide. The aforementioned message adapter allows banks to continue using existing payment message formats and operational processes without adopting blockchain-specific workflows.IBM is also expanding Digital Asset Haven to a localized deployment beta version, which can be installed on IBM Z and IBM LinuxONE in the client's own data center for managing digital assets such as stablecoins and tokenized deposits, without relying on public cloud infrastructure. IBM stated that the platform and key management layer are fully retained within the client's own environment, with keys protected by IBM Crypto Express hardware security modules.

StarkWare stated in an update on September 23 that the estimated GPU computing cost for preparing a quantum secure Bitcoin (QSB) transaction has dropped to below $67, a decrease of about 79% compared to the approximately $320 computing expenditure for the first similar mainnet transaction in August. According to StarkWare, the first QSB transaction was packaged and confirmed on August 26, with the engineering work completed by Tomer Giladi, and submitted directly through MARA's Slipstream service. The preparation process consumed about 3100 GPU hours, utilized around 100 GPUs, and incurred a computing cost of approximately $320, excluding Bitcoin network transaction fees.This cost reduction resulted from the quantum secure Bitcoin optimization challenge initiated on September 16 by StarkWare, Yukon Research, and Eigen Labs. The challenge invited developers, researchers, and AI agents to optimize transaction construction software, ultimately resulting in 62 adopted improvements across two computational tasks required to prepare a QSB transaction, with benchmark tests showing an estimated computing cost reduction of about 79%. The relevant dashboard currently indicates that the estimated cost has further decreased to $66.The QSB proposal was released by StarkWare researcher Avihu Levy in April, introducing hash-based quantum attack protection for transactions without altering Bitcoin's consensus rules. Due to limited cost, complexity, and applicability, he described it at the time as an emergency measure while continuing to advocate for adjustments at the protocol level.

The venture capital firm a16z crypto stated that the trading of perpetual contracts linked to stocks, gold, and other traditional assets has rapidly increased, with more transactions occurring on-chain. In August 2026, the transaction volume reached $117.3 billion, up 44 times from a year earlier, with open interest at $4.8 billion. After a decline in transaction volume in April 2026, it hit a new high again in May, rising to $145.1 billion in July, before falling back to $117.3 billion in August.Open interest increased from $161 million in July 2025 to $4.8 billion in August 2026, nearly a 30-fold increase, remaining close to record highs even as transaction volumes declined. As of November 2025, centralized exchanges accounted for about two-thirds or more of monthly transaction volumes, with December nearly evenly split with on-chain venues; in August 2026, on-chain venues accounted for 86%, approximately $101 billion, while centralized exchanges accounted for about $16 billion, with their transaction volume declining from a peak in March to July.The decentralized perpetual contract platform Hyperliquid launched HIP-3 in October 2025, allowing developers to deploy their own perpetual contract markets using the shared trading infrastructure HyperCore. That month, the on-chain RWA perpetual transaction volume increased to about $4 billion, with on-chain venues accounting for nearly half of the tracked transaction volume in December. A year ago, commodities accounted for 84%, while in August this year, stocks accounted for 48%, commodities for 28%, and indices for 18%. In June, the open interest for stocks was $1.6 billion, surpassing commodities at $1.2 billion, and in August, they were $2.2 billion and $1.6 billion, respectively.

Documents disclosed on Tuesday local time show that accounts under Trump completed 1,156 securities transactions in July, with a total scale ranging from 79 million to 270 million dollars, buying at least 43.6 million dollars and selling at least 35.6 million dollars, indicating a large-scale portfolio adjustment.On July 20, the account sold between 5 million to 25 million dollars of Microsoft and Amazon stocks, marking the largest single transaction of the month. On the same day, it sold between 1 million to 5 million dollars of Oracle stocks and bought between 500,010 to 1 million dollars of Nvidia stocks. Three days later, the account slightly replenished its positions in Microsoft and Amazon. Additionally, Trump also traded related assets of SpaceX and Tesla under Musk that month.

The Alpenglow upgrade of the blockchain network Solana has entered the public testnet, where developers will test reducing transaction finality from about 13 seconds to 0.15 seconds, or 150 milliseconds. This upgrade will replace Solana's existing TowerBFT consensus system with Votor, allowing validators to confirm blocks through one to two rounds of direct voting, but the way users send funds will not change.The first testnet migration requires using Agave 4.3 and does not currently support Firedancer or Frankendancer. The mainnet update on September 28 is still a tentative arrangement and not a confirmed launch date for Alpenglow.

Jurrien Timmer, Global Macro Director at Fidelity Investments, stated on platform X that trading in the AI sector has been in a "dead money" state for over three months, with the token spending and GPU rental rates he tracks remaining flat or declining, while only memory (DRAM) prices continue to rise.Timmer believes that AI will change life in the long term and may unleash a productivity miracle, raising the non-inflationary speed limit of the economy to a level sufficient to sustain global debt. However, before that, the current construction is inflationary, and the returns on the trillions of dollars invested in computing power remain uncertain, with corporate equity and debt capital demand growing at a rate of $3.3 trillion.
