Spot crypto sold off overnight while miners and DeFi forums printed the real tape. The CoinGecko snapshot fetched at 00:34 UTC on September 16, 2026 put Bitcoin at $75,790, down 2.8%. Ether was $2,402.83, down 4.3%. Solana was $97.14, down 5.4%. Global market cap sat near $2.59 trillion, bitcoin dominance about 58.5%, and 24-hour volume about $105.1 billion.
The overnight stack is power, parameters, and venue rails. Soluna said ERCOT conditionally classified its 100 MW Dorothy campus as Base Load. Z Squared closed a $5 million preferred-stock purchase of a bitcoin-mining campus in Arkansas. Aave posted a GHO rate and GSM-fee update, a batch of V3 cap changes, and a wstETH liquidation test that still cannot verify financing. Researchers tied recursive STARKs to cheaper log indexes. A new ERC would put per-item NFT supply on-chain. Kraken delayed Solana funding for most of the day, then marked it resolved.
Soluna: ERCOT tags 100 MW Dorothy campus as conditional Base Load
Soluna Holdings said in a September 14, 2026 press release furnished as Exhibit 99.1 to a Form 8-K that ERCOT has conditionally classified its 100 MW Project Dorothy campus as Base Load in Batch Zero. The company already had a conditional Base Load tag for the full 166 MW at Project Kati last week, which it says puts 266 MW across both Texas campuses in that bucket. Dorothy is a 100 MW wind-powered campus in Briscoe County, Texas, behind the 150 MW Briscoe Wind Farm Soluna acquired in April 2026, with Dorothy 1 and 2 at 98 MW of energized capacity; Soluna also submitted a 50 MW extra interconnection request at the site. The classification is conditional pending ERCOT verification, Batch Zero replaces project-by-project study, and the 8-K is Item 7.01 Regulation FD disclosure, not a 10-K.
Z Squared closes a $5 million preferred deal for an Arkansas mining campus
Z Squared Inc. said in a September 14 Form 8-K that on September 8, 2026 it closed the purchase of 100% of Paradox Data, LLC from Paradox Infrastructure LLC, paying 5,000 shares of newly designated Series A Convertible Preferred Stock with an aggregate stated value of $5,000,000. Paradox Data's principal asset is the Union County Campus in El Dorado, Arkansas: about three acres, an existing building, and a contract to buy about 10 adjacent acres, with an Entergy Arkansas interruptible service agreement for up to 8,000 kVA (about 8.0 MW) still held by the seller. A $1-per-year lease lets the seller keep running its bitcoin mining facility until electric service and control transfer, Entergy consent to assign the power agreement has not been obtained, and the company remains obligated for up to four more milestone payments in Series A preferred with an aggregate stated value of up to $20,000,000, for a $25,000,000 cap if every milestone hits. The filing flags a related-person transaction because CTO Jeffery Harris holds an indirect minority stake in the seller.
TokenLogic posted a September 2026 GHO Stewards update at 19:02 UTC on September 15. Over the 30 days to September 14, GHO/USD traded 6.7 to 13.6 bps under par and last stood 12 bps under $1.00, about 10.5 bps below USDC and 9.2 bps below USDT, while Horizon GHO debt rose from 23.2 million to 39.0 million, a 68% increase. The proposal raises the Horizon GHO base rate from 3.00% to 3.25% (Core stays 4.25%, Prime 3.84%), lifts the Monad USDC GSM GhoReserve limit from 25 million to 50 million and the USDC exposure cap from 40 million to 50 million, raises USDC GSM buy fees from 10 to 15 bps on Ethereum, Monad, and Arbitrum, and cuts the Ethereum USDT GSM buy fee from 15 to 10 bps. Mint fees stay at zero; TokenLogic says the Horizon rate change goes through Risk Stewards and the GSM changes through the GHO Risk Council.
Aave Risk Stewards retune V3 caps as weETH and USDe sit near full
LlamaRisk posted Aave V3 cap and interest-rate changes at 09:26 UTC on September 15, citing user behavior, on-chain liquidity, and position health. On Core it would lift the weETH supply cap from 1,350,000 to 1,500,000 after 98.0% utilization, cut sUSDe from 450 million to 250 million, and cut PT-srUSDe-22OCT2026 from 75 million to 10 million. On Plasma it would raise the USDe supply cap from 450 million to 550 million after 100% utilization, cut the USDe borrow cap from 335 million to 100 million, and drop USDe Slope1 from 1.00% to 0.25% on Plasma, Monad, and Mantle. Other cuts include Base WETH supply 169,000 to 125,000 and borrow 143,000 to 100,000, cbETH 75,000 to 50,000, and Monad WETH supply 20,000 to 10,000 and borrow 12,400 to 7,500.
wstETH liquidation test: financing still unverified on Aave mainnet
GBQuant posted a mainnet wstETH liquidation assessment at 11:41 UTC on September 15, run against Aave V3 Ethereum at block 25,780,402. The 99th-percentile simultaneous repayment under a published two-day stress is $7.15 million of debt and $7.58 million of collateral received; the worst 1% of scenarios average $24.14 million and $25.59 million. Oracle crash-through and simultaneous-repayment tests pass, and a 6% bonus covers the tested size, but the money-to-repay test is INDETERMINATE because an atomic liquidator can only cover about $1.29 million against stated depth, leaving $5.86 million that needs committed capital the post does not verify. The overall result is INDETERMINATE, not FAIL, and the author says a listing proposal should document eligible liquidators and committed capital.
Researchers: recursive STARKs could make log indexes cheap enough to rival state
On Ethresear.ch at 12:37 UTC on September 15, zsfelfoldi argued that post-quantum signature size makes recursive STARK transaction pre-authorization, as proposed in EIP-8288, a likely high-priority upgrade path. In that world, the on-chain cost of statelessly verifiable witness data falls, including log query proofs based on EIP-8304 Trustless Log Index tables, which the post says could become a viable alternative to the state tree with a much lower write cost. EIP-8304 would process small index tables of up to 256 blocks in the core protocol and validate further merges on-chain with ZKPs, so the index stays available at the chain head. The note is a research argument, not a shipped network upgrade.
Draft ERC-8417 would cap NFT supply per item, not just per collection
On September 15, 2026, Dojun Lee and co-authors opened GitHub pull request 2010 on ethereum/ERCs adding draft ERC-8417, Itemized Non-Fungible Token, with a matching Magicians discussion thread. The draft extends ERC-721 so each token records which item it belongs to and the contract holds a write-once supply cap per item, refusing any mint that would exceed it. ERC-721 only tracks a token id and owner, and collection-wide supply says nothing about how many of one in-game item or ticket class may exist; an optional extension adds edition numbers such as 42 of 100 on-chain. The status is Draft, created 2026-09-01 in the header, and it is not a deployed standard.
Kraken resolves a day-long Solana deposit and withdrawal delay
Kraken opened a Solana funding-delay incident at 02:30 UTC on September 15, saying deposits and withdrawals on the SOL-USDC gateway may be delayed while other funding methods were operating normally. Components listed were Digital Currency Funding for Solana (SOL) and USDC on Solana. A fix was in by 09:43 UTC with new deposits and withdrawals processing and a backlog still clearing; Kraken marked the incident resolved at 20:12 UTC. It was tagged minor impact, not a chain halt.
