NethermindEth/juno v0.16.1 on GitHub

⚠️ This update is required to support Starknet 0.14.3.

Additionally, it brings considerable performance improvements as well as a more streamlined user experience when interacting with the node.

Added

Feeder client improvements to heavily reduce network bandwidth reducing the cost for all of Starknet users.
Reduced heap allocations when encoding/decoding field elements (i.e. felts) making RPC requests response parsing 50% cheaper. #3565

Improved UX by grouping flags when --help is used. #3620
- Additionally, the --help message is no longer displayed when there is an error on node startup. #3613 -

New --help preview:

Network & L1 Flags:
      --disable-l1-verification   Disables L1 verification since an Ethereum node is not provided.
      --eth-node string           WebSocket endpoint of the Ethereum node. To verify the correctness of the L2 chain, Juno must connect to an Ethereum node and parse events in the Starknet contract.
     ...

Sync & Polling Flags:
      --preconfirmed-poll-interval duration   Sets how frequently pre_confirmed block will be updated(0s will disable fetching of pre_confirmed block). (default 500ms)
      --prelatest-poll-interval duration      Sets polling interval for pre-latest block updates. (0s will disable polling). (default 1s)
      ...

Gateway Flags:
      --gw-api-key string    API key for gateway endpoints to avoid throttling
      --gw-timeouts string   Timeouts for requests made to the gateway. Can be specified in three ways:
...

Changed

L1 head is updated on startup, allowing RPC consumers to see a consistent L1/L2 heads immediately, instead of after a short while. #3594
- Additionally, when the L1 head is ahead of the L2 chain height (during node sync), an RPC request for the L1 head will return the current chain height to avoid inconsistent responses. #3644
Removed a core Rust dependency by rewriting the Cairo Zero class hash calculation in pure Go, getting a performance improvement and memory cost reduction of 20%. #3648
Bump RPC spec version to 0.10.2. #3573

Fixed

starknet_estimateFee and starknet_simulateTransactions rejecting transactions with a non-zero tip when the account balance could cover the fee. The maximum L2 gas bound now accounts for the tip, matching the blockifier's fee calculation. #3562
Startup RPC calls are now bounded by per-call timeouts so a slow or unresponsive L1 endpoint cannot hang node startup indefinitely. #3676
