Robinhood Chain’s ~$33 million in fees over 15 days outpaced Solana and BNB Chain combined, with ~90% retained as revenue.

Visa's stablecoin settlement tops $20B run rate

Visa’s stablecoin settlement volume just blew past a $20 billion annualized run rate - up 15x year-over-year, with 160+ stablecoin-linked card programs live and payment volume on them up nearly 200%. This is no longer a pilot. It’s a settlement rail that’s eating into traditional card economics.

The catch: a working-capital gap. Issuers must fund daily settlement before collecting from cardholders, which ties up cash. Credit Coop is solving that with a stablecoin-denominated revolving credit facility, secured by settlement receivables and automated via smart contracts. It has cut borrowing costs up to 30% for participants. Rain has financed ~$2B through it with zero defaults since 2023. If you run a card issuer, this is the template for not bleeding cash on float.

Ethereum targets quantum-safe L1 by 2029

The Ethereum Foundation published a tier list for the Hegotá upgrade, and two proposals are “must-ship.” FOCIL (EIP-7805) lets a validator committee force-include valid transactions, strengthening censorship resistance. Frame Transactions (EIP-8141) makes account abstraction native by splitting transactions into programmable “frames.”

The bigger news: December 2029 is now a firm target for full quantum resistance across execution, consensus, and data layers. The Foundation treats it as non-negotiable until reassessed in January, and is explicitly planning for “Q-day” - when quantum computers could break current cryptography - arriving as early as 2030. If you hold ETH or run validators, this is your timeline for migration. Don’t assume it slips.

Crumbs launches stock-token shopping rewards on Robinhood Chain

Crumbs is now offering stock-token rewards for shopping on Robinhood Chain. The pitch: spend with partner merchants, earn tokenized equity instead of points. It’s a loyalty program with a secondary market built in, which means the rewards have a price that can tank or moon.

For engineers, the interesting part is the settlement layer. Stock tokens on a chain require custody and compliance rails that typical ERC-20s don’t. If Crumbs is doing this right, it’s tokenizing actual shares with a regulated custodian. If not, it’s a points program wearing a securities costume. Watch the fine print.

Hunter Biden to launch $LAPTOP memecoin on Base

Hunter Biden’s $LAPTOP memecoin goes live on Base today, September 9. The tokenomics earmark 20% of supply for investors who lost money on $TRUMP and include a conditional burn mechanism tied to 30-day performance targets. Miss the targets, and a portion of supply gets burned; hit them, and the burn is redirected.

This is closer to a prediction market instrument than a conventional memecoin - outcome-based supply changes mean the price encodes a bet on whether the targets get hit. If you’re trading it, you’re not buying a meme; you’re buying a binary option with extra steps. Don’t confuse the two.

How Hegotá should approach gas repricing

A new ethresear.ch post argues for a conservative approach to gas repricing in Hegotá. The key proposals: EIP-8131 and EIP-8279 unify data pricing across calldata, access lists, and blob hashes, while EIP-7923 replaces quadratic memory expansion with linear per-page charges plus a hard 64 MiB transaction cap. Both are judged low-disruption relative to their scope.

The controversial stuff - zkEVM-oriented EVMification changes (EIPs 7666, 8200) and BLOCKHASH repricing (EIP-7709) - should only ship if EIP-8025 does. The fork’s scope hinges on a data-availability scale target: if that target holds, data repricing is essential. If the upgrade gets narrowed, contested proposals get deferred. For dApp developers, this determines whether your gas costs change by 5% or 30%. Plan accordingly.

Coldcard hacker moves 45% of Bitcoin stolen in third attack wave

The serial campaign against Coldcard users continues. In the latest documented wave, the attacker moved 45% of the Bitcoin stolen, and the funds have so far evaded all interdiction attempts. This is the third distinct attack wave, and each cycle follows the same pattern: compromise, steal, then methodically move funds.

If you’re a Coldcard user, this is not a firmware bug - it’s likely a supply-chain or social-engineering vector. Treat your device as potentially compromised if it came from an untrusted channel. The fact that 45% moved without being frozen suggests the attacker has a mature laundering operation. Don’t expect the funds back.

B2B over B2C for neobanks

The argument: neobanks should target businesses, not consumers. Consumer accounts are a commodity with no moat - everyone offers a free checking account. Business banking, by contrast, generates far more volume per customer and creates switching costs through integrations, payroll, and invoicing.

Only a handful of players do this well globally, despite there being 350M businesses that need banking. If you’re building a neobank, the data says stop chasing retail deposits and go after the SMB segment. The unit economics are better, and the churn is lower.

'The chain is now earnings': Bernstein sees upside for Robinhood

Bernstein reiterated an Outperform rating on Robinhood Markets with a $160 price target (31% upside). The thesis: Robinhood Chain generated $33 million in fees over a 15-day window, outpacing Solana ($11 million) and BNB Chain ($9 million) over the same period.

Robinhood retains ~90% of collected fees, with Arbitrum receiving 10% for infrastructure and Ethereum under 1% for data availability. That converts chain activity into a direct revenue stream on the income statement. The chain is now earnings, not just a user retention play. If you’re evaluating Robinhood as an investment, the chain’s fee capture is the number to watch.

Bear case on agentic micropayments

The counter-argument to the x402 hype: agentic micropayments have a fundamental problem - they require agents to hold value and make decisions about spending. That’s a trust and security nightmare. One compromised agent can drain a wallet in seconds.

The bear case isn’t that the tech doesn’t work; it’s that the failure modes are unacceptable for production systems. Until agents have robust attestation and spend limits, micropayments will stay a demo, not a default. If you’re building agent infrastructure, plan for the day your agent gets pwned and can spend freely. It’s coming.

RedotPay responds to FBI Hamas affidavit

RedotPay published a compliance update after an FBI affidavit referenced the company. The response includes an independent review of its AML/CFT controls across its operations. The details are thin, but the move is defensive: get ahead of the narrative before regulators or partners ask harder questions.

For anyone running a crypto payments business, this is a reminder that compliance isn’t optional. An FBI affidavit naming your company is an existential event. If you don’t have independent audit trails and clear AML procedures, you’re one subpoena away from losing your banking partners.
