Web3 Weekly: August 24–31, 2026 — Stablecoin rails draw capital as Solana prepares a larger transaction format

From August 24 through August 31, 2026, at the channel's 9:00 a.m. ET cutoff, capital announcements clustered around tokenized financial products, clearing and custody, and cross-border stablecoin settlement. The week also brought a CFTC insider-trading order tied to prediction-market contracts and a Solana transaction-format upgrade headed for testnet. The SEC and ESMA produced no new in-window action that changes the rulebook or MiCA status in the sources checked.

The week in one read

Funding: City Protocol reported $11 million across seed and pre-Series A rounds for onchain structured-product infrastructure. RQD* Clearing announced a separate $74 million minority growth investment, while SBI said it would acquire a 20% stake in Ajaib Group for $270 million to extend yen-stablecoin and blockchain settlement infrastructure in Southeast Asia. The three transactions belong in different buckets: cumulative venture funding, growth capital for a financial-market infrastructure firm, and a strategic stake in a brokerage.
US regulation: The CFTC ordered Gabriel Perez to pay $172,000 for trading presidential-mention event contracts with material nonpublic information. The order also imposed a three-year trading ban. The SEC's Crypto Task Force page listed an August 26 written submission on institutional tokenization; a submission is policy input, not a Commission order or new rule.
EU MiCA: ESMA's dated news page showed no MiCA, CASP, or crypto-asset ruling from August 24 through August 31. Its newest listed item in the period was an August 18 consultation on reporting by recognized third-country central counterparties, outside this window and outside the channel's crypto scope.
Layer 2: No new qualifying Layer 2 launch was verified in this window. The current protocol item is a Solana base-layer transaction-format upgrade, not an L2 milestone.
Protocol upgrade: Solana Transaction v1 is headed for late-August testnet. The format raises the maximum transaction size from 1,232 bytes to 4,096 bytes and keeps legacy and v0 transactions working while RPC providers, explorers, indexers, and wallets prepare for a new serialization format.

Funding: three different forms of institutional crypto capital

The week's three largest capital announcements should not be added into one venture-funding total. City Protocol reported a cumulative amount across named round types. RQD* Clearing received growth capital for a regulated-market infrastructure business. SBI described a planned acquisition of an equity stake in Ajaib Group. The different structures change what a reader should ask next.

City Protocol: $11 million across seed and pre-Series A rounds

City Protocol said on August 26 that it had raised $11 million across seed and pre-Series A financing rounds. The named backers include Dragonfly, Jump Crypto, CMT Digital, Stratified Capital, Adaverse, Mirana, and other investors. City Protocol is building infrastructure for issuing, operating, and distributing structured investment products onchain. Its Venzo platform covers strategy vaults for quantitative hedging, cross-exchange arbitrage, private credit, and onchain yield. 1

The announcement supports the $11 million cumulative figure and the investor list. The announcement does not give a fresh-money split between the seed and pre-Series A rounds. Deal teams should therefore record the amount as a reported cumulative total until the company publishes the round-by-round breakdown. Venzo's product description also leaves a diligence question: the financing announcement describes the strategy categories and vault mechanics, while independent performance, liquidity, and redemption data require separate review.

RQD* Clearing: $74 million growth capital for clearing and custody

RQD* Clearing announced a $74 million minority growth investment led by Bain Capital Tech Opportunities, with participation from ABN AMRO Clearing Bank and Nyca Partners. Bain said the funding would support expansion across North America, Asia, and the Middle East, plus technology and product investment. The company's planned digital-asset scope includes custody infrastructure and tokenization for financial institutions. 2

RQD* is a clearing and custody business rather than a Web3 protocol. The deal belongs in the channel because its stated product expansion reaches digital assets and tokenized markets. Founders and investors should keep the transaction separate from early-stage project funding: the amount measures growth capital for a market-infrastructure firm, not a priced seed or Series round for a crypto network.

SBI–Ajaib: $270 million for a 20% stake

SBI Holdings plans to acquire a 20% stake in Ajaib Group for $270 million, with closing targeted by the end of August. CoinDesk reported that the investment would give SBI a route into Indonesia's online brokerage and digital-asset market while it expands JPYSC, its yen-denominated stablecoin, across Southeast Asia. The companies also plan cross-border, blockchain-based settlement infrastructure. 3

The structure matters. The public report describes a planned strategic stake, not a conventional venture round. The investment also combines a distribution channel, a stablecoin expansion plan, and a regional settlement strategy. Investors tracking stablecoin adoption should watch the closing, JPYSC availability, local licensing, custody arrangements, and the point at which a proposed blockchain settlement network reaches production.

Regulation: one enforcement order, two quiet rulemaking surfaces

CFTC: a $172,000 insider-trading order for event contracts

On August 28, the CFTC announced an order settling charges against Gabriel Perez. The order says Perez used material nonpublic information obtained through his federal government employment to trade presidential-mention event contracts on a prediction-market platform. The contracts reflected words or phrases that the President might use in speeches.

Perez must disgorge $107,539.02 in trading profits and pay a $65,000 civil monetary penalty, for a combined amount of $172,539.02. The order also requires him to cease and desist from further violations and imposes a three-year trading ban. The CFTC said the trading occurred from December 2025 through February 2026 while Perez worked as a White House teleprompter operator and had access to speeches before delivery. 4

The order applies to a specific conduct pattern: access to confidential information, trading in contracts tied to that information, and personal profit. Prediction-market operators should map access controls and surveillance around employees, contractors, market makers, and data providers who can see sensitive event inputs. Traders should treat the CFTC's order as an enforcement precedent for information handling, rather than as a new product rule.

SEC: an August 26 submission is policy input, not a new action

The SEC's Crypto Task Force written-input page listed an August 26 submission from Monica Pagano of ERC Genesis titled Institutional Tokenization: From Digital Representation to Market Architecture. The page classifies the submission under crypto ETPs, custody, public offerings, security status, tokenization, and trading. The page also says written inputs are posted without modification and do not necessarily represent the views of the Commission or the Task Force. 5

The status is the point. A written submission adds material to a public policy record. It does not create a safe harbor, authorize a tokenized product, or change the legal status of an asset. The SEC's formal Regulation Crypto Assets proposal was announced on August 18 and covered in the prior issue; this week's update adds no new SEC enforcement action or effective crypto rule in the sources checked.

EU MiCA: no qualifying ESMA action in the window

ESMA's dated news page lists its newest item as an August 18 consultation on the reporting framework for clearing activity at recognized third-country central counterparties. The page lists no MiCA, crypto-asset, or CASP ruling dated August 24 through August 31. 6

The finding is narrow. It covers the dated ESMA News surface and does not establish that every national competent authority was quiet. Compliance teams should continue checking ESMA's interim MiCA register and the relevant national regulator for licensing, passporting, and service-scope changes. A quiet ESMA week supplies no new EU authorization or exemption.

Layer 2: no new qualifying launch verified

No new Ethereum Layer 2 mainnet, public testnet, or comparable launch met the channel's inclusion standard in the August 24–31 window. The current Solana item is a base-layer transaction-format upgrade. A protocol upgrade, a prior testnet milestone, or an ecosystem funding announcement does not count as a new Layer 2 launch.

Builders should therefore treat the Layer 2 beat as a watch item this week rather than infer a launch from adjacent infrastructure news. A qualifying entry would need a named network, a dated public testnet or mainnet event, and enough technical information to evaluate deployment, bridge, sequencer, gas-token, and liquidity implications.

Protocol upgrade: Solana Transaction v1 heads to testnet

Solana Transaction v1 was reported on August 24 as a protocol format headed for late-August testnet. The design is specified in SIMD-0296 and SIMD-0385. Transaction v1 introduces version byte 0x81, moves compute and priority-fee settings into a fixed header mask, removes Address Lookup Tables from the new format, and raises the maximum transaction size from 1,232 bytes to 4,096 bytes. 7

The larger payload gives zero-knowledge proofs, large multisig transactions, and BLS signature schemes room to fit in one atomic transaction. The change also creates work for the infrastructure that reads and relays transactions. Block explorers, analytics platforms, RPC providers, wallets, and indexers need to understand the new serialization format and test how existing Address Lookup Table patterns translate.

Legacy transactions and the current v0 format remain supported. The upgrade therefore creates a compatibility window rather than a forced migration. Developers can test locally with solana-test-validator v4.2 or later and Surfpool, while the public testnet timing remains the event to watch. The secondary report also said preliminary feature-gated mainnet work began in the Agave 4.2 release cycle on August 17; that work is preparation, not a confirmed mainnet activation.

The reader-facing distinction is between payload capacity and network performance. Transaction v1 gives complex transactions more room. The report does not establish a mainnet activation date or promise a proportional increase in throughput. Teams should measure serialization, fee estimation, simulation, block parsing, and indexer behavior against the testnet before changing production assumptions.

What deserves follow-up

Founders and deal teams

Record City Protocol's $11 million as a reported total across seed and pre-Series A rounds until the company discloses the fresh-money split.
Separate RQD* Clearing's $74 million growth investment and SBI's planned Ajaib stake from venture-round totals. Compare the businesses by licensing, custody, distribution, and settlement scope.
For City Protocol, request vault-level performance, redemption, liquidity, and smart-contract risk information before comparing Venzo with conventional structured-product infrastructure.
For Ajaib, track the stake closing, JPYSC distribution, Indonesian regulatory permissions, and the production status of the proposed settlement infrastructure.

Compliance teams and counsel

Use the CFTC Perez order to review how employees and contractors handle material nonpublic information that can affect event contracts.
Treat the SEC written submission as public policy input. Track later Commission releases, proposed texts, comment records, and effective dates separately.
Keep the ESMA and national-authority checks on the weekly list. A quiet ESMA News page does not establish a license, passport, or exemption.

Traders and market-structure teams

Watch prediction-market surveillance and information-access controls after the CFTC's three-year trading ban and disgorgement order.
Treat the SBI–Ajaib transaction as a distribution and settlement signal, not as evidence that JPYSC has already reached broad regional use.
Separate RQD* Clearing's digital-asset custody plans from live production capabilities until the company publishes product and market-access details.

Protocol operators and infrastructure teams

Test Solana Transaction v1 parsing, simulation, fee handling, and serialization against the late-August testnet when it becomes available.
Keep v0 and legacy transaction paths working while applications add v1 support.
Review every dependency that assumes a fixed transaction size or Address Lookup Table behavior, including indexers, RPC services, explorers, and wallet transaction builders.

Watchlist for August 31–September 7

Solana: confirm the Transaction v1 public-testnet activation and look for developer-tool, RPC, indexer, and wallet compatibility notes. 7
CFTC: monitor follow-up orders or guidance involving event contracts, prediction-market information controls, and exchange surveillance after the Perez action. 4
SBI and Ajaib: check whether the planned 20% stake closes by the end of August and whether the parties publish concrete JPYSC distribution or settlement milestones. 3
City Protocol: look for a breakdown between the reported $11 million cumulative total and the new pre-Series A capital, plus product-level data for the Venzo vaults. 1
ESMA and national regulators: check for a new MiCA authorization, passporting record, CASP supervisory action, or crypto-asset ruling. The current ESMA News page supplies no qualifying item for August 24–31. 6
SEC: follow the formal Regulation Crypto Assets comment process and later Commission action; the proposal's $5 million and $75 million pathways remain proposal-stage items rather than available exemptions. 8
