TeraWulf lifts Muskie contracted power from 500 MW to 1 GW
TeraWulf's October 5, 2026 8-K, accepted at 08:21 UTC, says wholly owned DB Long Hunts Data LLC signed amended and restated Kentucky Power transmission and energy service agreements on October 1, 2026. Contracted capacity at the Muskie Data Campus in eastern Kentucky rises from 500 MW to 1 GW, and the second 500 MW phase moves from 2030 into 2029, subject to Kentucky Public Service Commission approval and Kentucky Power's construction schedule. The first 500 MW phase is still aimed at a 2028 ramp. The same 8-K says TeraWulf intends to upsize its senior secured revolver and raise additional senior secured debt for letters of credit, with no assurance either raise closes.

Grayscale adds Anchorage Digital as a second Zcash ETF custodian
The Zcash ETF's October 5, 2026 8-K, accepted at 16:37 UTC, reports that on September 29, 2026 sponsor Grayscale Investments Sponsors, LLC signed a sixth amendment to an August 8, 2025 master custody agreement so the Trust became a party with Anchorage Digital Bank N.A. Anchorage, an OCC-chartered national trust bank, will custody a portion of the Trust's ZEC. Coinbase Custody Trust Company, LLC remains the primary custodian, and the sponsor has not yet set how much ZEC will move. Anchorage generates and holds private keys in a U.S. hardware security module and must keep commercial crime insurance or a fidelity bond of at least $100 million. In a Zcash fork it may pause and choose which branch to support.

Aave Snapshot passes Sentora's first V4 Hub and Spoke instance
Sentora's ARFC to run externally curated Hub and Spoke instances on Aave V4, and to authorize the first Ethereum instance, closed on Snapshot at 09:54 UTC on October 5, 2026. Final scores were about 360,060 voting power for, 378 against, and 360,438 total. Hub liquidity would be borrowable only as RLUSD, PYUSD, or OUSD, with other listed assets as 0% rate, zero-draw collateral, and three initial spokes plus a later PYUSD Yield spoke. Sentora would run risk parameters through AccessManager roles, including a 48-hour delay on risk-increasing changes, while Aave DAO keeps contract ownership via the Short Executor. The ARFC says Aave risk service providers have no mandate to monitor that instance.

Spark Snapshot would rotate Morpho guardian and curator Safes
Phoenix Labs posted a Spark technical scope on October 5, 2026 at 07:57 UTC to rotate the Morpho guardian Safe 0xf5748bBeFa17505b2F7222B23ae11584932C908B from 3-of-5 to a 2-of-3 Operational GovOps set, and the standard curator Safe 0x0f963A8A8c01042B69054e787E5763ABbB0646A3 from 3-of-5 to 2-of-2, on Ethereum and Base. The Safe addresses stay the same; Sentora RLUSD curator Safes are not in this batch. Endgame Edge and BA Labs backed the scope the same day, and a sparkfi.eth Snapshot poll opened at 16:09 UTC on October 5 and runs through 16:09 UTC on October 8. The post still marks the execution window as TBD and says the four Safe transactions are not atomic across chains.

Spark discloses an X Layer spUSDC vault already taking USDC
A October 5, 2026 Phoenix Labs post says Spark Savings deployed a segregated Diamond PAU and spUSDC vault on X Layer, with a matching Ethereum PAU that parks bridged USDC in legacy sUSDC and returns liquidity through CCTP v2. Atlas provision A.6.1.1.1.3.10 authorized the work outside the spell process. A 1 USDC test from a party other than Designated Contributors landed at 10:24 UTC on September 23, OKX On-chain Earn was announced at 03:00 UTC on September 25, and a 883,420.34 USDC deposit followed at 01:28 UTC on September 26. Spark governance acceptance is due by March 23, 2027, six months after that first non-contributor interaction, or the setup is supposed to wind down.

Lido would drop Wormhole and use 2-of-3 bridges on BNB Chain
A October 5, 2026 Lido research post asks to remove the Wormhole adapter from a.DI governance forwarding to BNB Chain and cut the confirmation threshold from 3-of-4 to 2-of-3. Wormhole shut down automatic Standard Relayer delivery on April 1, 2026. The Lido adapters still point at relayer 0x27428DD2d3DD32A4D7f7C497eAaa23130d894911, and the Ethereum quote for BNB Chain has been 0 since block 24788662 on April 2, 2026 at 01:34 UTC. With only Chainlink CCIP, LayerZero, and Hyperlane still delivering, a 3-of-4 rule now fails if any one of those three lags. The post prefers 2-of-3 because it restores one-bridge outage tolerance without new code, at the cost of a two-bridge forgery margin, and notes the CrossChainExecutor owns wstETH on BNB Chain with no delay.
