Silicon, the Polygon CDK layer 2 built in 2024 by South Korean exchange Korbit (now DigitalX) with Ozys and Hidow, stopped accepting deposits this week and will switch off its network and explorer after December 31. About $9.75 million in USDC, WBTC, ETH and USDT remains on the chain and must be bridged out by users themselves.
The Arbitrum-built Ethereum layer 2 that Robinhood launched on July 1 saw decentralized-exchange volume climb from $989 million on Aug 28 to $1.6 billion on Sept 1 and $3 billion on Sept 4, with Uniswap handling about 98% of it and burning a record 184,000 UNI in a day.
Core developers on the Sept 3 consensus call discussed a builder-deposit caching bug and non-finality at the Glamsterdam activation on the latest devnet, affecting Lighthouse, Prysm and Teku. A post-call recap puts the Sepolia fork at Oct 6, later than the Sept 28 slot proposed in August.
US spot ether ETFs posted their first net outflow in 12 sessions on Sept 2, led by redemptions from BlackRock's ETHA, Fidelity's FETH and Grayscale's ETHE, while BlackRock's staked-ether fund ETHB took in $52.9 million. Flows turned positive again on Sept 3 and 4.
Ethereum developers are urging contract, wallet and infrastructure teams to test upcoming gas-cost changes before the Glamsterdam upgrade reaches mainnet.
