Proposal 68 passed with 99.4% support and 58% participation, but exchanges must confirm the swap before a second vote sets the snapshot, claims and shutdown schedule.

Arc, Circle's USDC-native Layer 1 for institutional stablecoin finance, is now available through Chainstack Global Nodes, Dedicated Nodes, and Chainstack Self-Hosted, as the network opened with eleven founding validators including BlackRock, DTCC, Visa, and Mastercard.

The Layer 1 charges gas in USDC and runs proof-of-authority across a permissioned set of 11 institutions plus Circle. More than 100 applications are live at launch, with Aave, Morpho and Uniswap anchoring DeFi. Circle minted 10 billion ARC tokens this week without committing to a public launch.

Solarious announced that its Renewable Energy Monetization Layer-1 blockchain went live on September 1, 2026, bringing its Proof-of-Energy system into live operation, recording signed solar-generation data and issuing SOLAR tokens from accepted production records.

The chain kept $943,728 on Sept. 10 against $5.44 million on Sept. 4, its lowest daily take since Aug. 29. Transactions were flat and decentralized exchange volume over the week rose 27%. The average transaction cost $0.077 in gas, against $0.43 at the peak.

FOCIL and Frame Transactions are the two must-ship proposals. A tapered issuance burn and a mandatory burn of execution rewards were declined because the cluster said issuance and reward policy belong in a broader ecosystem process.

The plan would snapshot ONE at the final block and redirect emissions to an AI video business, but Harmony urged users to exit smart contracts before Sept. 10 because onchain apps and liquidity pools will not migrate.

Blocks came every 101 milliseconds throughout the outage reported on Friday. The chain's transaction data went missing on Ethereum for exactly 14 minutes, across two gaps. Arbitrum blamed Ethereum's blob market, which fits the second gap and not the first.

Users paid $4.45 million to transact on the network on Sept. 2, more than Ethereum, Solana and Tron combined, after the base fee rose 23 times off its 0.02 gwei floor. Robinhood absorbs the cost inside its own wallet app until Sept. 29.

The Arbitrum Foundation's first-half report puts $360,000 of Arbitrum Expansion Program license fees at 35% of ArbitrumDAO's July income, the first month Robinhood Chain ran on mainnet.
