StarkWare's OffMarket Hides Polymarket Bets

StarkWare opened OffMarket to the public, a privacy app that lets people trade on Polymarket without linking positions to their known wallets.

Orders still fill on Polymarket at the same prices. Funds sit in Starknet's shared privacy pool, which holds about $1.5M across 17,000 deposits, and deposits are capped at $1,000 USDC per account for now. The app is non-custodial and follows Polymarket's geo rules, so US users are blocked. A compliance firm holds a master viewing key for court and regulator requests.

Trade size and timing can still reveal a trader. OffMarket is not a Polymarket product; it runs through Polymarket's verified builder program.

Polymarket Weighs a POLY Token Against an IPO

Polymarket weighs a token or IPO as its next step, Bloomberg reports. CEO Shayne Coplan teased an announcement ahead of TOKEN2049, but neither path is confirmed.

A token could reward traders and liquidity providers in ways shares cannot, while an IPO fits Polymarket's push into regulated US markets through QCEX and Polymarket US. Coplan first hinted at $POLY in October 2025. Polymarket says it never announced an airdrop or a token launch.

Its valuation rose from about $9B after ICE's 2025 investment to reported talks above $20B, with annualized revenue said to be well above $1B.

BNY & Citadel Run First Tokenized Treasury Repo

BNY and Citadel tested tokenized Treasuries in a live repo trade. Citadel Securities bought a 2-year Treasury note, and its token settled on BNY's private ledger in minutes, not T+1.

Citadel then used the tokenized note as collateral in an overnight triparty repo, with BNY lending cash against it. BNY calls it the first use of tokenized assets on a major triparty repo platform. The bank oversees $62.6T in assets under custody and administration.

Next, BNY plans tokenized deposits for onchain settlement and longer settlement hours, reaching European and Asian trading hours next year.

Kraken Parent Payward Buys Lithuania's Saldo Bank

Payward is buying Saldo Bank, according to the Financial Times. The deal would give Kraken's parent its own EU bank licence and is expected to close in 2027 after regulatory approval.

Saldo started as a Finnish fintech and got a specialised bank licence from the European Central Bank in October 2021. Run from Vilnius, it offers consumer and SME loans, term deposits and credit cards in Lithuania, Finland and Sweden. Deal terms were not disclosed.

It follows July reports that Kraken wanted a full banking licence in Lithuania, the same route Revolut took in 2018.

Coinbase Urges Bitcoin to Start Quantum Prep Now

Coinbase shared its Bitcoin quantum plan. The custodian holds about 5% of all BTC and says work should start before a quantum computer can break today's signatures, since the migration will take years.

Its priorities: an address type that can swap signature schemes without a redesign, which BIP-360's P2MR or P2TRv2 could offer, plus a 1-of-2 bridge where the same coins are spendable with a classic key or a quantum-safe one. Coinbase is wary of stateful schemes like SHRINCS unless a stateless fallback exists, since reused state can let attackers forge signatures.

Still open: what happens to coins that never move. Coinbase wants that debated separately, so it does not hold up adding quantum-safe signatures.

Rain Launches Stablecoin Wallets for Fintech Apps

Rain launched embedded stablecoin wallets for partner apps. One balance lets users get paid, spend with a Rain card at 175M merchants and send money in 50+ currencies.

Custodial wallets and yield on balances are planned by the end of 2026. Rain, valued at $1.95B in January, also runs Western Union's Stablecard program.

Solana's Alpenglow Upgrade Hits Mainnet Oct 21

Anza set the Alpenglow mainnet launch for October 21 at about 14:50 UTC. Its Votor consensus replaces TowerBFT and cuts finality from about 12.8 seconds to roughly 150ms.

Validators will exchange votes directly instead of posting them on-chain, so reported TPS will drop: votes are about 63% of all Solana transactions today. Validators need Agave 4.3.0+ and at least 0.8 SOL in their vote account; Firedancer and Frankendancer, about 15.8% of stake, are not supported at launch. Alpenglow went live on testnet on September 24 and devnet on September 25.

The switch happens in a single slot on the running network, with no restart. Rotor, the planned replacement for Turbine block propagation, is not scheduled yet.

NFT Market in 2026: Only 21 of 56 Early Marketplaces Still Alive

Blur's website goes offline on November 12, and it is far from alone. Of 56 top NFT marketplaces launched in 2017-2023, only 21 still trade.

The other 35 shut down, sold, pivoted or turned into zombies, lasting 3.9 years on average. Six exchange and retail NFT shops closed, from Coinbase to Binance.

Fees collapsed with volume: OpenSea earned $25.1M in 2025 against $1.55B in 2022, and monthly NFT sales fell 91% from December 2023 to $167.2M in September 2026.

Trezor Cuts Resellers After Ledger Implant Scandal

Trezor is cutting its reseller network so it can check the sellers it keeps more closely. It calls the move preventive and says there is no evidence its devices were compromised.

The trigger is the Ledger supply-chain attack: wallets sold by reseller CryptoBilis in Southeast Asia carried LTE implants that read seed phrases off the screen. Bitquery puts the losses at about $93M. Trezor had already removed CryptoBilis from its network, saying none of its devices sold there were affected.

Ledger asks anyone who suspects a tampered device to contact its support and file a police report, and points other buyers to its inspection guide.

DRW and Marex executed a swap onchain on Derivnex, the first OTC derivative tied to a fully tokenized index: S&P DJI's iBoxx USD Liquid Investment Grade Index on Canton.

Kaiko tokenized the index with access rules that keep S&P DJI's licensing controls, and supplies the official values used to price the position. Derivnex runs the trade as a Canton smart contract, so both firms share one synced record. The trade size was not disclosed.

Next, Derivnex plans to link swap positions with digital cash and collateral on Canton, so margin and payments run on the same rails.

South Korea Blocks 27 Offshore Crypto Exchanges

Korea's FIU blocked 27 exchanges operating without registration, including KuCoin, BitMart, MEXC and Phemex. Their sites will be cut off and they must stop serving Korean users.

Only 28 providers are registered with the FIU, and 44 unregistered operators were referred to investigators. In 2025, KuCoin, MEXC and 12 others were already pulled from Google Play and the App Store in Korea. KuCoin says user assets remain safe.

The FIU urged users to check whether their exchange is registered and to withdraw from unregistered ones now, as funds may be hard to recover later.

First 100 days since mainnet: which chain traded the most?

Robinhood Chain did $99.7B in spot DEX volume in its first 100 days and crossed $100B on day 101.

The next-best launch ever tracked, Unichain, did $13.0B in the same window. That's 7.7x less. Base did $2.4B, 41x less.

The hype isn't tokenized stocks: they make up under 10% of the chain's DEX volume. The real flow is memecoins. The Pons launchpad and CASHCAT drove it.

HyperDex launched spot and perpetuals aggregation, with the documented spot router spanning 69 chains, 36 bridges and 39 exchanges while users retain custody.

Binance Lists RWUSD Yield Product With Zero Fees

Binance is listing RWUSD, its own yield product. RWUSD/USDT spot trading opens Oct 13 at 08:00 UTC with zero maker and taker fees until further notice.

RWUSD launched in July 2025 with up to 4.2% APR: users subscribe with USDT or USDC 1:1 and earn daily rewards from Binance's ecosystem income and real-world assets like US Treasury bills. Until now it could not be traded. Deposits and withdrawals are still off, and redemptions pay out in USDC.

RWUSD also becomes Cross Margin collateral at the same time, though borrowing it is not available yet. Zero-fee Convert trading follows within an hour of the spot listing.
