Full changelog-
Mainnet Denim pinned for November 5, 18:00 UTC
base/base set denim_timestamp 1793901600 for chain 8453 (#6124). Only v1.5.1-rc.7 and later carry it; stable v1.5.0 still reads None, and Base has not announced the date yet.
-
Validity: nonce live on Mainnet, block bound tip
Upstream confirmed the nonce predicate is live on Base Mainnet. The page now says to set the block_number bound to the latest block plus 10 right before signing.
-
Bridges page: fast bridges, aggregators, messaging
Added a bridge-type comparison (standard vs fast vs messaging), Across/Relay/Stargate, the Jumper and Bungee aggregators, and Chainlink CCIP and LayerZero V2 (Base endpoint ID 30184) for multichain tokens.
-
Sepolia Denim set for October 21, 18:00 UTC
The status page scheduled the Sepolia Denim fork (timestamp 1792605600, window to 20:00 UTC). Operators need v1.5.0 or later and must drop --enable-experimental-validity-transactions first.
-
Batched forwarding insert on main
New --tx-forwarding-batched-insert flag (#5816, main only) sends a batch as one base_insertValidatedTransactions call, up to 1024 txs. Off by default; builders must serve it first.
