Ether was $2,455.44, up 0.5%. Solana was $105.33, up 1.0%. XRP was $1.39, up 0.4%. Global market cap sat near $2.63 trillion, bitcoin dominance was about 59.5%, and 24-hour volume was about $43.5 billion.
The SEC sent a custody-rule rewrite to White House review. PowerCompute rolled a collared loan against 307 bitcoin. Grayscale Ethereum Classic Trust will switch its NAV index on September 1. Solana marked SGP-0002 Accepted, with the SIMD-0550 feature gate still ahead. Circle listed native USDC and EURC on Plasma. TokenLogic asked Aave Risk Stewards to cut WETH Slope 1. Ethresear.ch opened a temporal-liquidity research thread. Magicians split native account abstraction into three EIPs.
SEC custody rewrite enters White House review, text still hidden
The Office of Information and Regulatory Affairs logged SEC RIN 3235-AN46, titled Amendments to the Custody Rules, as received on August 25, 2026. The pending EO 12866 record lists the agency as the SEC, the stage as Proposed Rule, no legal deadline, and economically significant. The Unified Agenda abstract says the Division is considering recommending amendments or new rules under the Investment Advisers Act of 1940 and the Investment Company Act of 1940 to modernize custody of advisory client and fund assets, including crypto assets. It flags an EO 14192 deregulatory designation and an NPRM target of October 2026. The proposal text is not public. This is a review receipt, not a Commission vote and not a final rule.
PowerCompute borrows $21.9 million against 307 bitcoin on a collar
PowerCompute, Inc. filed an 8-K accepted August 28, 2026 for events dated August 25. Through US Digital Mining and Hosting Co, LLC it entered a non-recourse, collared, 30-day loan with ChainFi Inc. doing business as Arch Lending, then borrowed $21,892,131.88 secured by 307 bitcoin at 6.5% per annum. About $18.1 million paid off the August 3 Arch loan, and $3.765 million funded that older loan's collar, which had a bitcoin ceiling of $66,370. The new collar sets a floor of $71,112, a ceiling of $75,000, and a barrier of $93,500 for the first 30 days, then can roll unless a party gives notice of non-renewal. If bitcoin sits below the floor at maturity the borrower may walk away, repay and recover collateral, or roll by curing the shortfall. Excess above the ceiling is for Arch if the reference price meets the barrier.
Grayscale Ethereum Classic Trust switches NAV to a CoinDesk Benchmark Extended Rate
Grayscale Ethereum Classic Trust (ETC) filed an 8-K on August 27, 2026 under Item 8.01. Before September 1, 2026 the Trust valued ETC for operational purposes against the CoinDesk Ethereum Classic Price Index. Effective that date the Index will be the CoinDesk Ethereum Classic Benchmark Extended Rate, and NAV and NAV per Share will use the Index Price based on that rate. The filing describes a U.S. dollar composite meant to mute fraud and anomalous prints, provide a volume-weighted fair value, and handle non-market events. This is a pricing-input change, not a new listing.
Solana marks SGP-0002 Accepted, with SIMD-0550 still the activation path
The Solana governance-proposals repo now lists SGP-0002, Double Disinflation Rate, with status Accepted. The SGP asks validators and delegators to endorse doubling annual disinflation from 15% to 30% while keeping the 1.5% terminal rate and the existing reward mechanism. It estimates the faster taper shortens the path to that floor from about 5.7 years to about 2.8 years and cuts roughly 18.9 million SOL of emissions over six years, about 2.6% below the current schedule. The text says the SGP depends on SIMD-0550 being accepted and activated through the normal feature-gate process, so the Accepted mark is a mandate, not a live inflation change. Client teams still have to ship the gate, tests, and activation behavior.
Circle lists native USDC, EURC, CCTP, and Bridge Kit on Plasma
Circle's blog says USDC, EURC, CCTP, and Bridge Kit are now available on Plasma, an EVM-compatible layer-1 built for high-throughput stablecoin apps. It points to MiCA-compliant dollar and euro rails, 1:1 redeemability, and CCTP transfers that move USDC without wrapped assets, with Bridge Kit billed as about 10 lines of code. Users can access USDC through Plasma One, Plasma's stablecoin app and card. Circle published mainnet addresses: USDC 0x2d661C89D812261039AF9764eceaAee884f5F67F and EURC 0x3ee196e78d4d4248b849b8e1c7f44c5457fafd2c. Eligible teams get Circle Mint on/offramps. This is an issuer listing, not a TVL print.
TokenLogic asks Aave Risk Stewards to cut WETH Slope 1 to 2.20%
TokenLogic's August 27, 2026 forum post recommends reducing WETH Slope 1 to 2.20% on Ethereum Core, Arbitrum, and Optimism, while keeping Base unchanged. Ethereum Core still holds about 1.74 million WETH of variable debt, roughly $4.1 billion and about 96% of Aave WETH borrows, with Base next at about 76,000 WETH. Ethereum Core Slope 1 has sat at 2.35% while consensus-layer APR fell about 25 basis points year to date, from about 2.77% to 2.52% between January 1 and August 23, 2026, as stake rose to about 42.4 million ETH, or 34.7% of supply. The post is a Risk Stewards recommendation, not a completed on-chain change.
Ethresear.ch opens Temporal Liquidity, not an EIP yet
On August 28, 2026 at 05:59 UTC, an Ethresear.ch post titled Temporal Liquidity: heterogeneous demand and Ethereum's single execution lane opened the Temporal Liquidity Market research program. The authors argue a transaction's value depends on when it executes, but Ethereum offers one 12-second-slot lane priced by a scalar fee. Liquidations decay in a slot or two, treasury settlements hold for hours then drop, and oracle updates depend on staleness, yet none of that shape is visible to the protocol. They say excluded demand never shows up as congestion, so the base fee reacts to the wrong signal. This is a research thread, not an EIP and not a fork schedule.
Magicians split native account abstraction into EIP-8398, EIP-8399, and EIP-8400
A Magicians thread posted August 27, 2026 sketches Composable Native Account Abstraction as a split of the earlier EIP-8130 work. EIP-8398 would cover a portable keystore, actors, authenticators, account creation, configuration, and portability. EIP-8399 would add a native 0x79 transaction using that authority model, with batching, sponsorship, and keyed sequential nonces. EIP-8400 would add optional policies, account locking, and nonce-free transactions on the same envelope. The post says EIP-8130 remains unchanged and points to an EIPs pull request opened 05:03 UTC on August 27. These are draft interfaces, not a hard-fork vote.
