Hyperliquid said it intends to make Payward the first CFTC-regulated deployer on its HIP-3 markets. The upgrade would let deployers restrict access through onchain allowlists, which could let regulated operators run US perpetual futures on Hyperliquid's infrastructure. Bitnomial, Payward's CFTC-regulated exchange and clearinghouse, would be the deployer, and NinjaTrader Clearing would carry client accounts if approved. The functionality is live on testnet, and the deployment still needs regulatory approval. It is unclear how permissioning would work or whether it would include built-in KYC. Payward first announced the plan on September 16.

Mizuho cut its Circle price target to $43 from $45 and kept Underperform. That implies about 46% downside from Monday's $79.84 close, which was down 7% on the day. The analysts say AI personal assistants are a “marked risk.” In their simulation, agents steer USDC holders toward higher-yielding FDIC-insured options like SoFi savings, and even crypto-only users toward other platforms. They estimate USDC's market cap could shrink by $4B to $9B and reserve revenue could fall 10% to 20% over the medium term. Only about 17% of USDC sits on Circle's platform, which pays no yield, versus 30% on Coinbase and 53% elsewhere. Under faster AI adoption, they project 2027 average USDC at $101B (from $108B), reserve revenue down 5% to $4.1B, and adjusted EBITDA down 5% to $603M.

Binance founder CZ has confirmed BNB Chain is building a new EVM-compatible parallel Layer 1 that will run alongside BNB Smart Chain, connected through a native bridge with BNB serving as the gas, staking, and governance token. The chain targets high-frequency trading and real-time payments with 200-millisecond block times and 20-millisecond pre-confirmations. Planned features include native account abstraction and onchain privacy pools. An internal multi-validator devnet is already live, with public testnet targeted for late 2026 and mainnet for early 2027.

Spark, a Bitcoin offchain payments protocol from Lightspark, Flashnet, and Breez, exposes all user transactions to operators by default, a privacy gap shared by Ark, Bark, and Wavelength. Zark addresses this by layering a ZK co-signing protocol on top of Spark leaves without modifying the base protocol, structuring user-to-user transfer messages as ZKPs that prove payment validity without revealing transaction details to operators, and using a 2-of-2 signature scheme pairing a Zark co-signer with Spark operators. The main bottleneck is arbitrary-denomination payments through SSPs, where each leaf swap must prove and verify independently, pushing settlement times up to 10 minutes for complex combinations. The implementation is a regtest proof-of-concept, with aggregate ZK proving across batches identified as the path to practical settlement speeds.

Onchain options represent 6.9% of Deribit's volume, but infrastructure constraints around regulation, market-making, and RFQ systems are now resolved, leaving distribution of retail taker flow as the primary barrier to growth. Retail has been the growth driver in each major options market: US contracts tripled from 4.19B to 15.2B between 2017 and 2025 after Robinhood launched commission-free options, 0DTE options grew from 5% to over 60% of S&P 500 index volume in a decade, and India's NSE now processes 34.7B equity index contracts per year, 89% of global volume. The Korea case study illustrates the offshore spillover opportunity: after regulations cut domestic retail participation by 85%, Korean retail shifted offshore and now trades 3.6x more there than at home, positioning onchain venues to capture demand displaced from over-regulated local markets.

The carry trade has existed across four onchain generations: 2020 incentive-subsidized yield farming, liquid staking carry via stETH on Aave at 90-95% LTV, Ethena-style funding-rate carry, and tokenized credit collateral backed by $14.4B in tokenized Treasuries, $8.1B in tokenized credit, and $4.3B in active strategies. The carry math at stage four: a 9% yielding asset at 75% LTV and 5% borrow cost produces 17% ROE at 3x leverage, but carry turns negative near 10% borrow rates. The piece proposes a seven-factor collateral screen covering yield spread, yield stability, price stability, price quality, issuer redemption speed, secondary liquidity, and capacity, applied across asset-backed lending, digital credit, reinsurance, and active strategies.

Fireblocks denied Visa acquisition rumors at a ~$2.5B valuation on Thursday, then confirmed a 7% workforce reduction (60-70 jobs) the following day. The rumored deal price represents a 69% markdown from the company's $8B 2022 peak valuation, and this marks the company's third round of layoffs in recent years despite having raised approximately $1.04B in total capital. The sequence of events raises questions about the state of institutional crypto infrastructure valuations and whether Fireblocks is managing toward an exit at materially lower terms than its last primary raise. On the same day, American Express announced cutting roughly 5% of its workforce, with its CFO citing AI-driven restructuring, adding to a broader pattern of financial services firms shrinking headcount ahead of automation-driven operating model changes.

Keystone disclosed a breach in which an attacker pivoted from a compromised third-party monitoring tool to access 25,964 buyer records, 12,873 incomplete checkout records, and the WebAuth device authentication key burned into hardware during manufacturing. That key cannot be erased from existing units and is the mechanism for verifying device genuineness, meaning an attacker now has the capability to produce counterfeit Keystones that pass authentication checks. Keystone is destroying all 18,835 devices in current inventory, suspending all unshipped orders, and halting production under the compromised key until new-key devices are ready. User assets, recovery phrases, and private keys were not affected. A Shopify data-erasure tool failure caused customer records to be retained beyond the company's 180-day policy, widening the exposure window.

Morpho's fees are set at the market level, so they come out before curators or lenders are paid.

BlackRock, SBI Holdings, and Startale signed an MOU to explore connecting tokenized money market funds with SBI's yen stablecoin JPYSC.

BitMine's holdings rose to 6,051,933 ETH, about 4.95% of supply, with 5.23M ETH staked.

Y Combinator sent Mochatrade's $500K seed round in USDC on Base via three transfers on a Friday evening when bank wires were unavailable, completing in seconds.
