Robinhood Wallet is Robinhood's self-custodial crypto wallet, separate from Robinhood Chain, the company's public Arbitrum-based layer 2. Crossmint is a checkout provider that lets apps sell memecoins for card payments. Merchant category codes tell card networks what a purchase is. Code 5815 is for digital goods and media. Crypto purchases are often excluded from ordinary card rewards and can face extra restrictions. Crypto Briefing, citing The Block's earlier investigation, said some Crossmint-powered buys were coded as digital media, that JPMorgan Chase flagged the coding, and that Visa confirmed at least one misclassified transaction. It also said the arrangement allowed up to $1,000 a day without KYC, with a $1 million total cap. Fomo is a separate memecoin app named in the same reporting. The change, as described, would recode supported memecoin card buys as crypto transactions rather than stop them. Crossmint's comment that its procedures have not changed, and the still-live checkout, are the limits of what is confirmed. Next week is not a calendar date from Visa.

Robinhood Chain went to public mainnet on 1 July 2026 as an Ethereum layer 2 built on Arbitrum. Official docs still describe it as permissionless, EVM-compatible, and aimed at tokenized stocks and other real-world assets, with ETH as gas. In practice, a late-August memecoin wave made it one of the most expensive networks. CoinDesk said applications earned $2.7 million on 30 August, with token launcher Pons and memecoin terminal GMGN supplying about $2 million as users created 22,600 tokens in 24 hours. At the early-September peak the chain took about $8 million in fees on 13.1 million transactions, or about 64 cents each. By 16 September that was about 2.6 cents. CoinDesk's seven-day comparison through 16 September has Pons volume down 37% to about $616 million and Pons protocol revenue down to $5.8 million, while Uniswap V3 volume on the chain more than doubled to $5.3 billion and Uniswap V4 fell 22% to $4.9 billion. Weekly DEX volume across venues rose 5% to about $12.8 billion to $13 billion. Solana DEX volume in the same week was about $17 billion, down 8%, so the data does not show Robinhood users simply moving there. deBridge flows were a modest net $2 million from Robinhood Chain to Solana. growthepie's 19 September snapshot still ranks the chain first among tracked networks by transaction count, with daily active addresses around 414,000. App revenue on that print was about $6.12 million, far above chain fees. These are third-party indexed figures, not a Robinhood audited report, and they do not split tokenized stocks from memecoins.

Robinhood Chain is Robinhood's permissionless Ethereum Layer 2, built on Arbitrum technology, using ETH for gas and aimed at tokenized stocks and onchain apps. HOOD Summit is the company's annual event. A 10 August newsroom post already set Houston for 29-30 September. The 16 September teaser does not change those dates. In late September, Central Time is daylight time (UTC-5), so 5:30 p.m. CT is 22:30 UTC. Specific chain, wallet or brokerage features remain unnamed until the keynote.

Sunrise lists outside assets onto Solana so wallets and DEXs can point at one mint instead of competing copies. Backpack Securities is the issuer named on the listing. Tokenized stocks on Solana can trade when traditional U.S. cash-equity markets are closed. Raydium is a major Solana DEX. StonkFun, posted by @LaunchOnSF , lets users launch new coins paired with the stock token. BlackBerry is a software company whose QNX system Raydium said is used in more than 275 million vehicles. That product note is not a claim about token economics. Earlier Sunrise listings this week, including CYPH, used the same issuer-and-canonical-mint pattern. The Sunrise and Raydium posts do not describe how a holder redeems into a traditional brokerage share, who holds the underlying equity, or who is allowed to buy it. Secondary recaps that add 1:1 redemption or extra wallet names are not a substitute for those issuer terms.

Sanctum runs liquid staking on Solana. CLOUD launched with a large Community Reserve. Sanctum has said only about 48 million of an original roughly 307 million in that reserve was ever distributed, and that the leftover pool deterred investors who treated it as overhang. The burn vote, run through MetaDAO decision markets, authorizes destroying the remaining 259 million from that reserve. Sanctum's Strategic Reserve, described earlier as about 110 million tokens for compensation, talent, and grants, was outside the proposal. The ticker change to SANC is a name, symbol, and logo update. Sanctum has said tokenomics and the token address stay the same. A passed vote is permission to burn, not proof the tokens are already gone. The investor dashboard at investors.sanctum.so is the project's own tokenomics page to recheck after any burn lands.

ZetaChain launched in 2021 as a layer 1 meant to connect other blockchains. In 2026 the team says its working product is Anuma, a private AI chat app that keeps encrypted memory under the user's wallet keys and routes prompts across many models. The 17 September proposal would make ZETA a native Solana token, keep the ticker and total supply, leave Ethereum and BSC ZETA untouched, and shut the ZetaChain L1 after holders move. Staking on Solana is still being designed. Exchange support is not automatic. The vote opened with the 17 September post and was described as running 72 hours, which puts the announced close on 20 September after this edition's cutoff. Until then validators keep running. Readers should treat the outcome as pending.

Coinbase Tokenized Stocks are meant to represent real share ownership held by a custodian, including events such as dividends and splits, rather than a synthetic price token. @base has repeatedly said they are only available in eligible jurisdictions outside the United States. The $1 billion figure is an official Base claim. This check did not independently re-tally DEX prints. Base's 19 September recap also said network stablecoin market cap had reached $5 billion and that Cobalt will add validity transactions, which execute only when stated onchain conditions are met. Separate Morpho markets for borrowing USDC against a small set of those stock tokens were already live before this window, with early usage still small in 18 September coverage, and those markets are not for U.S. persons. Readers should treat the $1 billion headline as cumulative activity on Base, not as proof of deep, two-sided liquidity in every ticker.

Account abstraction is the effort to make crypto wallets work more like normal apps: passkeys instead of seed phrases, apps paying fees, and several steps in one click. Base and Ethereum spent months trying to agree on one transaction format. Those talks failed, leaving EIP-8130 and EIP-8141 on separate tracks. CoinDesk reported that wallets covering both networks may have to support two formats. On 19 September Base's own recap added that EIP-8130 would ship later this year and that Cobalt will introduce validity transactions, meaning signed transactions that the chain includes only if onchain conditions match. The official Cobalt overview still does not list EIP-8130 among Cobalt features. Sepolia is marked for 23 September and mainnet for 30 September. Those dates are announced shipping targets, not a guarantee, and they have no hour attached on the docs page. This still matters because Base is pushing B20 stock tokens, Coinbase Wallet, and consumer apps that will inherit whichever wallet standard actually ships.

Arc is Circle's layer 1, public mainnet since 16 September 2026, with USDC as gas. x402 is an HTTP payment standard that lets APIs and agents charge per request. A facilitator checks a signed payment and posts it onchain so the seller does not run a node or fund gas. Circle's hosted Facilitator Service does that for USDC using EIP-3009 transfer-with-authorization. Sellers can try it without an account, then need a Circle API key to settle. Circle says it screens both parties and pays settlement gas. The service is software from Circle Technology Services, LLC, and is not described as a custody product. Because settlement also runs on Base, this item belongs with Arc but matters to Base builders too.

Arc opened public mainnet on 16 September as Circle's USDC-gas chain. Microgrants sit beside Arc Studio and Portal as a way for early apps to get a $500 USDC payout after verification, rather than a priced token sale or a guaranteed venture round. The program still requires a live mainnet link. Circle and Arc already-funded work is excluded. The close time is announced, not a promise that 20 awards will be paid.

Blink is a Bitcoin Lightning wallet that offers custodial accounts, where Blink holds the keys, and non-custodial balances, where users hold their own. The company's first public notice at 12:41 UTC on 19 September said services were paused while it investigated. It said the large majority of funds were secure and that non-custodial wallets were not affected. Later the same day it narrowed the impact to a few dozen custodial accounts and said those users need take no action to be reimbursed. The restore post said the vulnerability behind the incident has been fixed and verified. Affected accounts remaining locked is a containment step, not a statement that those users have already received funds back. Blink did not publish how the attacker got in, how much was withdrawn, or which country or vector was involved. Some secondary reports discussed whether the Spark Bitcoin payments protocol was involved. Blink's own posts do not name Spark. Until the promised post-mortem, that link is unconfirmed.

Injective is a separate chain built for onchain trading, tokenization, and related activity. Putting INJ into Solana launchpads, DEXs, and wallets means a Solana user can trade or launch against INJ without first opening an Injective-native app. Sunrise appearing on the list does not make INJ a tokenized stock. Pump.fun, Raydium, Jupiter, and Phantom are among Solana's most used launch, swap, and wallet surfaces. Injective's post does not publish contract addresses, circulating supply on Solana, or redemption mechanics. A same-day company post about Injective USDC and Noble USDC is a different asset-standard claim and is not covered here. Readers who want to use INJ on Solana should verify the mint inside the named app rather than relying on the screenshot list alone.

NMS stocks are the listed U.S. equities that trade on national market system venues. Tokenizing them has been legally awkward in the United States because an AMM pool can look like an unregistered exchange and a liquidity provider can look like a dealer. The Innovation Exemption is a five-year, conditional order, not a new statute. It creates Tokenized Securities Venues that may run permissioned AMM pools for tokenized NMS stock. Tokens must carry the same rights as the listed share, including dividends and voting. Issuers get notice and can object when a third party tokenizes their stock. Contracts must be public and on a public permissionless chain. Trading must halt if the primary exchange halts. Coinbase's existing Base stock tokens, Sunrise listings on Solana, and Robinhood Chain stock tokens are not automatically covered. A venue still has to operate as a TSV and meet the conditions. U.S. eligibility for those products remains a separate question. The order also seeks public comment on possible changes.
