Base reported that its Denim upgrade was live on mainnet, while separate asset-recovery proposals involving Arbitrum and Polygon still required governance approval, according to Odaily’s November 6, 2026 roundup.
The distinction matters: the Base changes were described as deployed network functionality; the recovery measures were not yet authorized or completed.
Base: native 200-millisecond blocks
According to Base, Denim introduced native 200-millisecond block production, equivalent to five complete blocks per second. These native blocks replace the earlier Flashblocks preconfirmations. Each block has its own block number, hash, state root and receipts.
The upgrade also introduced BaseTime, which supports millisecond-level time precision for contracts. However, block.timestamp remains denominated in seconds—a distinction for developers assessing compatibility with existing contract logic.
Denim also changed the B20 token standard. Issuers can require approval of each transfer by a designated party, such as a transfer agent, and can use the same address list as either an allowlist or a blocklist.
Arbitrum: Binance seeks approval to recover frozen assets
Binance submitted a draft constitutional improvement proposal to the Arbitrum forum seeking the return of 8,425.997 ETH and 74.56 million ARB frozen following an attack on its hot wallet. At the time of the report, the assets remained in an intermediate freeze address on Arbitrum One and had not been returned.
Using November 5 CoinGecko prices, the report valued the ETH at approximately $19.6 million and the ARB at approximately $11.7 million.
The proposal must pass through forum discussion, a Snapshot temperature check and a binding onchain vote. Binance estimated that the process would take roughly seven weeks or longer.
Binance said its SAFU fund and corporate treasury would cover affected users’ losses. Recovered assets could offset incident-related losses and costs, including replenishing reserves used for compensation. The proposal does not request a new allocation from the DAO treasury.
The draft also includes legal conditions: submission of the onchain proposal and asset delivery would pause if legal proceedings prevented the transfer. Binance would first need to sign indemnification agreements with the Arbitrum Foundation, Offchain Labs and Security Council members.
Polygon: recovery hard fork remains a proposal
The roundup, citing Cointelegraph, reported that Binance and Polymarket proposed a Polygon hard fork to recover approximately 70.49 million stolen POL, valued at about $6.8 million.
The plan would move tokens from five attacker-controlled addresses to verified recovery wallets designated by the two platforms, without changing POL’s total supply. Approximately 23.86 million POL related to Polymarket addresses and 46.63 million POL to Binance addresses.
Polygon block producers had already blocked transactions from the affected addresses, but the report described that restriction as temporary and insufficient to return the funds. The recovery plan required governance approval and testing on Polygon Amoy. The source listed November 5 as the expected discussion date; it did not provide an outcome. No mainnet hard-fork date had been determined.
