What's new
Full changelog-
Native AA returns as Base Transactions in Everest
Upstream replaced EIP-8130 with Base Transactions (EIP-8430, type 0x79) and a new Everest fork. It keeps batching, sponsorship, token gas and parallel nonces, but drops passkeys. Everest has no date.
-
Added Base Transactions and Everest pages
New reference for the EIP-8430 format, payers, nonces, gas table, receipts and precompiles, checked against the node. Native AA, Cobalt, Beryl and devnet pages now point to Everest.
-
Tokenized Stocks API list is paged
The list endpoint now pages its results. A plain call returned 100 of 145 records, so code that reads only the first page misses tokens. The page now shows how to follow next_page_token.
-
Rewrote the local devnet guide
Devnet commands are now a just module (just devnet up-single, not just devnet), so the old recipe names failed. The page now covers endpoints, the fork schedule at blocks 20 to 25, and Everest/Zenith modes.
-
New base dev snapshot chain on main
base dev continues a downloaded snapshot as an L1-free local chain in one process, with a dev_impersonateTransaction RPC for funding. It is on main only; no release tag has it yet.
