v0.5.5

This is a minor release fixing a few issues, notably two issues causing starknet_estimateFee JSON-RPC endpoint to return errors or invalid fee estimations.

Added

• cairo-lang upgraded to 0.11.1.1

Fixed

• RPC emits connection logs and warnings
• Fee estimate mismatch between gateway and pathfinder
  • Gateway uses a new gas price sampling algorithm which was incompatible with pathfinders.
• Fee estimate returns error when submitting Cairo 1.0.0-rc0 classes.
• Historic L1 handler transactions are served as Invoke V0
  • Older databases contain L1 handler transactions from before L1 handler was a specific transaction type. These were
    stored as Invoke V0. These are now correctly identified as being L1 Handler transactions.

v0.5.4

The primary focus of this release is to provide support for Starknet v0.11.1, and will continue to work for v0.11.0. Since this release is required for v0.11.1, you should update your node before the network is updated.

Added

• Starknet v0.11.1 support
• CORS support via the rpc.cors-domains configuration option
• Transaction hashes are now verified as part of the sync process. Previously, these were not verified as the exact algorithm was underdocumented and the transaction format was still evolving.

Fixed

• RPC server panic for unprefixed unregistered method names
• Data can temporarily appear to go missing when transitioning from PENDING to ACCEPTED ON L2
  • This was commonly seen when rapidly monitoring a new transaction, which would go from PENDING to TXN_HASH_NOT_FOUND to ACCEPTED_ON_L2 as pathfinder moved the ephemeral pending data to latest data on disk.

Full Changelog: v0.5.3...v0.5.4

v0.5.3

0.5.3

Fixes for minor issues and inconsistencies.

Added

• max-rpc-connections command-line argument. This sets the maximum number incoming RPC connections the pathfinder node will accept. This defaults to 1024 if not specified.
• cairo-lang upgraded to 0.11.0.2

Fixed

• starknet_simulateTransaction data model inconsistency
• poll-pending default value restored to false
• incoming RPC connections limited to 100. This limit was accidentily introduced in v0.5.2 as part of a dependency upgrade, whereas before it was unlimited. The default is now 1024 and can be configured using --max-rpc-connections.
• handling of invalid JSON-RPC requests

v0.5.2

0.5.2

This release fixes a few RPC bugs and adds support for bulk fee estimation and transaction simulation (traces) as part of v0.3 RPC specification.

In addition it also adds a pathfinder_getTransactionStatus endpoint which lets you track a transactions status -- including REJECTED and RECEIVED -- in the same fashion as the gateway.

Added

• support starknet_estimateFee in the JSON-RPC v0.3 API
  • supports estimating multiple transactions
  • this includes declaring and immediately using a class (not currently possible via the gateway)
• support starknet_simulateTransaction for JSON-RPC v0.3
  • supports simulating multiple transactions
  • this includes declaring and immediately using a class (not currently possible via the gateway)
• support pathfinder_getTransactionStatus which is exposed on all RPC routes
  • this enables querying a transactions current status, including whether the gateway has received or rejected it

Fixed

• RPC returns int for entrypoint offsets instead of hex
• RPC rejects Fee values with more than 32 digits
• RPC does not expose pathfinder_getProof on v0.3 route

Full Changelog: v0.5.1...v0.5.2

v0.5.1

This is a minor bugfix release, primarily to fix an issue with syncing on testnet2.

Fixed

• pathfinder sometimes spams nethermind L1 nodes
• pathfinder stops syncing testnet2 at block 95220 due to a Sierra class compilation issue

v0.5.0

Highlights

• starknet v0.11.0 support
• RPC API v0.3 partial support
• removed several deprecated config options
• requires python 3.9 or 3.10 (no longer 3.8)

Changelog

Here is a quick overview of what's changed. More detail can be found in sections underneath.

Added

• support for state commitment and class commitment in pathfinder_getProof
• support for starknet v0.11
• partial support for RPC specification v0.3
  • exposed on /rpc/v0.3/ route
  • missing support for starknet_estimateFee and starknet_simulate

Changed

• starknet_call and starknet_estimateFee JSON-RPC methods return more detailed error messages
• python version requirement has changed to 3.9 or 3.10 (was 3.8 or 3.9 previously)

Fixed

• RPC accepts hex inputs for Felt without '0x' prefix. This led to confusion especially when passing in a decimal string which would get silently interpretted as hex.
• using a Nethermind Ethereum endpoint occasionally causes errors such as <block-number> could not be found to be logged.
• sync can miss new block events by getting stuck waiting for pending data.

Removed

• --config configuration option (deprecated in v0.4.1)
• --integration configuration option (deprecated in v0.4.1)
• --sequencer-url configuration option (deprecated in v0.4.1)
• --testnet2 configuration option (deprecated in v0.4.1)
• starknet_addDeployTransaction as this is no longer an allowed transaction since starknet v0.10.3
• RPC api version 0.1, which used to be served on path /rpc/v0.1

RPC API

We added support for v0.3 and removed v0.1. We still support v0.2 at both /rpc/v0.2 and /rpc (default) routes. In summary:

/                     # serves v0.2
/rpc/v0.2/            # serves v0.2
/rpc/v0.3/            # serves v0.3

We are missing starknet_estimateFee and starknet_simulate support for v0.3, which will be added in an upcoming release.

Python requirement

Note: this only applies if you are building from source. This does not impact docker users.

Pathfinder requires python to support the starknet VM used to simulate starknet transactions and function calls. Previous versions of the VM only worked with python 3.8 or 3.9 which was a hassle because most operating systems no longer directly support it. The new version of the VM bundled with starknet v0.11 now requires python version 3.9 or 3.10.

Configuration changes

Several configuration options are now removed, after they were deprecated in pathfinder v0.4.1. Here is a migration guide:

• --testnet2: use --network testnet2 instead
• --integration: use --network integration instead
• --sequencer-url: use --network custom in combination with --feeder-gateway-url and gateway-url
• --config: use environment variables or env files as an alternative

v0.4.5

Hotfix for a bug introduced in the previous version v0.4.4, which prevented a new node from syncing on blocks near genesis.

Added

• added Newton FAQ links to readme (thanks @SecurityQQ)

Fixed

• node fails to sync really old blocks

New Contributors

• @SecurityQQ made their first contribution in #799

Full Changelog: v0.4.4...v0.4.5

v0.4.4

This minor release contains some nice performance improvements for starknet_call and starknet_estimateFee; as well as some minor bug fixes.

Also included is a major new feature: storage proofs - big thanks @pscott for his hard work on this feature! This is available via the pathfinder_getProof method which is served from both the pathfinder and starknet endpoints for convenience:

• <node-url>/rpc/pathfinder/v0.1/pathfinder_getProof
• <node-url>/rpc/v0.2/pathfinder_getProof

The method is specified here. Its results can be used to formally verify what a contract's storage values are without trusting the pathfinder node. This is achieved by validating the merkle-proof that pathfinder returns and confirming that it correctly matches the known StarkNet state root.

Added

• storage proofs via pathfinder_getProof by @pscott

Fixed

• starknet_getEvents returns all events when from_block="latest"
• v0.1 starknet_getStateUpdate does not contain nonces

Changed

• improved performance for starknet_call and starknet_estimateFee by caching classes
• improved performance for starknet_call and starknet_estimateFee by using Rust for hashing

New Contributors

• @pscott made their first contribution in #726

Full Changelog: v0.4.3...v0.4.4

v0.4.3

The primary purpose of this release is to properly support testnet2 after the StarkNet v0.10.3 update. The v0.10.3 update changed the testnet2 chain ID which impacts transaction signatures which in turn meant that starknet_estimateFee would fail for any signed transaction. This release updates pathfinder to use the correct chain ID.

Fixed

• testnet2 and integration flags are ignored
• starknet_estimateFee uses wrong chain ID for testnet2

Changed

• updated to cairo-lang 0.10.3

Full Changelog: v0.4.2...v0.4.3

v0.4.2

Contains several bug fixes, mostly hotfixes for bugs introduced in v0.4.1.

Added

• document that --chain-id expects text as input

Fixed

• testnet2 and integration L1 addresses are swopped (bug introduced in v0.4.1)
• proxy network setups can't sync historical blocks (bug introduced in v0.4.1)
• ABI serialization for starknet_estimateFee for declare transactions
