ESMA gave crypto platforms three months to stop serving EU clients in stablecoins without MiCA authorization, setting a January 8, 2027 deadline.

In a formal opinion to national regulators, ESMA says platforms should not let EU clients buy, trade, swap or add to such tokens, and that warnings or disclosures are not enough. Only a time-limited wind-down is allowed: selling, converting, withdrawing, transferring or holding existing tokens. The opinion names no tokens, but CoinDesk points to Tether’s USDT and PayPal’s PYUSD as prominent examples.

The rule covers every MiCA service, from trading and exchange to custody, transfers and portfolio management.

Pyth DAO approved the 100% Rule: every dollar it receives from Pyth products now buys PYTH on the open market, up from a third of its treasury balance each month.

Under OP-PIP-136, one standing authorization replaces the monthly votes. The DAO gets 60% of revenue from Pyth Pro, Indices, Listing as a Service and the Data Marketplace. Pyth ended Q3 at $11.5M in active ARR, up 86% quarter over quarter, and Pyth-powered venues handled 94% of the $2.09T RWA perp volume.

The PYTH Reserve already holds 42M PYTH, and the token is up about 16% in the past 24 hours, per CoinGecko.

Securitize launched Securitize Stocks: tokenized US equities for eligible investors in the US, EU and beyond, starting with 12 names on Solana, settled in USDC.

Unlike price-tracking wrappers, each token is a security entitlement backed 1:1 by a real share, with dividends and voting rights where they apply, and the shares are never lent out. The first names include AAPL, NVDA, TSLA, CRCL and MSTR. Jump Trading makes markets, trading starts in extended hours with 24/7 planned, and the tokens are also expected on the NYSE’s upcoming 24/7 venue.

Ripple Prime and Aave plan to bring the tokens into institutional trading and DeFi collateral.

That's 7.1M BTC, about $589B. If ECDSA breaks, these coins could be taken without their owners doing anything.

Why now: on Oct 7, a day after OpenAI dropped 722 AI-made math results, Justin Drake said ECDSA could break before quantum computers do, "in the worst case in months not years". Vitalik agreed it "might fall even faster than expected".

The twist: it's mostly not Satoshi. His era's coins hold 1.71M BTC. Reused addresses hold 5.18M, 73% of everything exposed. That's wallets in use today, including Binance, Robinhood and Bitfinex cold storage, which Drake named directly.

The fix costs nothing: send to a fresh address and never reuse it.

Based warned its cardholders by email that someone got into an internal tool card provider Streamis uses to manage accounts. The access ran from Oct 3 to Oct 5, then was shut.

Exposed: full name, date of birth, phone, nationality, home address, passport number, email, Based wallet address and customer ID. Based says no funds moved and cards keep working. The real risk is the link between identity and wallet: attackers can now see who owns which balance, so expect phishing, scam calls and targeted threats.

So far Based has made no public statement on X, and the number of affected users is not disclosed.

Orca and Loopscale merged into Formation. The Solana DEX and lending protocol want to finance AI, energy, robotics and defense companies onchain, from issuance to loans and trading.

Loopscale co-founder Luke Truitt is CEO, and Orca’s Christopher Montagano becomes chief strategy and legal officer. Terms weren’t disclosed. ORCA and xORCA stay the core tokens, but a tokenholder proposal would cut automatic xORCA buybacks from 40% of fees to 10%, add 10% for team-run buybacks and send 80% to operations. Orca has handled $550B+ in volume since 2021, Loopscale has $150M+ in deposits and $2B+ in loans.

ORCA is up about 70% in a week to around $2.76, per CoinGecko.

Samsung is adding Solana stablecoins to Samsung Wallet and Samsung Pay. From the last week of October, users on 82M US Galaxy devices can send USDC abroad without leaving the app.

Built-in on- and off-ramps convert to and from local currency, with payouts to bank accounts in 60+ countries. Samsung won’t charge transfer fees, though receiving wallets or banks may. Coinbase custodies the USDC through Coinbase Prime, with Bastion as the licensed US stablecoin custodian. More markets will follow, subject to local rules.

Solana says it has processed over $5.25T in stablecoin volume in 2026, with PayPal and Western Union already on the network.

Block Scholes tested Bitget’s unified account, where 125 tokenized US stocks can back crypto positions. On a $1M portfolio, the capital needed fell from $340K to $175K.

The catch is correlation. Stock collateral falls together with the market, so the modeled portfolio hit liquidation after a ~21% correlated drop, versus ~27% if the same value sat in USDT. Since 2022, BTC’s 60-day correlation with the Nasdaq-100 has averaged +0.41.

The stocks keep working too: they still pay dividends in USDT and can be pledged to borrow stablecoins.
