All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
generate_random_felt()
for generating (pseudo) random felt value.- Printing information about compiling Sierra using
universal-sierra-compiler
- Displaying backtrace when contract call fails
- Tests config run is now executed in parallel resulting in faster
snforge test
setup in some cases
- You can skip
--name
flag when usingaccount import
- a default name will be generated. - Addresses outputted when calling
sncast account create
,sncast deploy
andsncast declare
are now padded to 64 characters length and prefixed with0x0
- Globally available configuration to store profiles to share between projects.
- Changed return type of
declare
in Cairo Deployment Scripts so it can handle already declared contracts without failing - Allow using
show-config
command without providing rpc url
- You can now use numbers without quotes as inputs for calls in multicall config file.
- New
--arguments
flag tocall
,invoke
anddeploy
for automatic conversion of Cairo expressions instead of serialized form.
- You can now pass arguments to
cairo-profiler
andcairo-coverage
. Everything after--
will be passed to underlying binary. E.g.snforge test --build-profile -- --show-inlined-functions
- You can't use now
--coverage
and--build-profile
flags at the same time. If you want to use both, you need to runsnforge test
twice with different flags. - Contract artifacts are compiled to CASM concurrently.
- Starknet artifacts are now loaded from all tests targets
- Cairo Edition in
snforge init
template set to2024_07
- Scarb features work with optimized compilation
- Custom test targets are now supported with optimized compilation
- Calling contract functions via safe-dispatcher now returns an
Err
when attempting to invoke a non-existent entry point, instead of causing a panic.
- Short option for
--accounts-file
flag has been removed. - Short option for
--contract-address
is now-d
instead of-a
. account add
is renamed toaccount import
.account import
can be now used without specifying--private-key
or--private-key-file
flags. Instead private key will be read interactively from the user.
account delete
command: It is no longer necessary to provide the--url
argument each time. Either the--url
or--network
argument must be provided, but not both, as they are mutually exclusive.
- When using test name filter with
--exact
flag, forge will try to compile only the selected test.
declare
andverify
commands now use the Scarbrelease
profile instead of thedev
profile as the default for building artifacts- StarkScan links now point to specific pages for transactions, contracts and classes.
- Explorer links displayed upon committing transactions are now properly formatted
sncast declare
no longer fails for flat contracts (i.e. CASM artifacts withbytecode_segment_lengths
being a number)
- Project generated by
snforge
containsassert_macros
dependency with version 0.1.0 for Scarb <= 2.8.0, otherwise equal to Scarb - Support for overriding fork configuration in test attribute with a different block ID, tag, or hash.
--no-optimization
flag that can be used to build contracts using the [starknet contract target](https://docs.swmansion.com/scarb/docs/extensions/starknet/contract-target.html#starknet-contract-target. This is the default behavior when using Scarb < 2.8.3
- For Scarb >=
2.8.3
contract artifacts are built as part of the test target now. This process speeds up the compilation time, but the behavior of the contracts potentially may not be 100% consistent with the real networks. It can be disabled using the --no-optimization flag snforge
now validates if your project is setup to generate debug info needed forcairo-coverage
when running--coverage
flag
- The package is now correctly versioned
- Derived
Debug
andClone
ontrace.cairo
items --coverage
flag to thetest
command. Saves trace data and then generates coverage report of test cases which pass and are not fuzz tests. You need cairo-coverage installed on your system.
latest
fork block id tag validation inScarb.toml
is now consistentRangeCheck96
,AddMod
,MulMod
builtins are now properly supported- Fixed escaping
'
in#[should_panic]
s - Fixed
scarb init
with snforge runner
- Support for Scarb features in
snforge test

snforge init
no longer emits warnings- Project template generated by
snforge init

cheatcode interface and compiles properly
- Bumped Cairo version to
2.7.0
- Max steps in tests (configured by argument
--max-n-steps
) now defaults to 10 million if not provided (changed from 4 million).
- Commands that commit transactions now display links to block explorers. When in human-readable mode,
invoke
,declare
,deploy
,multicall run
,account create
andaccount deploy
will display additional information with an url. A new key in Cast configuration -block-explorer
determines which block explorer service the displayed link leads to. Possible options are:StarkScan
,Voyager
,ViewBlock
,OkLink
,NftScan
.
-
account create
outputs hint about the type of the tokens required to prefund a newly created account with before deployment -
sncast
no longer expects--url
as a common argument. It is now required specifically by commands that utilise it, i.e.account add
,account create
,account delete
,account deploy
,multicall run
,script run
,call
,declare
,deploy
,invoke
,show-config
,tx-status
. Commands that do not require--url

removal, in favour ofselector!
usage
- the tool now always compiles Sierra contract artifacts to CASM using
USC
- before it used to consume CASM artifacts produced by Scarb if they were present. Setting upcasm = true
inScarb.toml
is no longer recommended - it may slow down the compilation. - The
replace_bytecode
cheatcode now returnsResult
with a possibleReplaceBytecodeError
, since it may cause unexpected errors down the line when not handled properly

cheatcode- result of the call to the trace
- added
--build-profile
flag to the--test

#[fork(...)]
attribute allowing testing against a network fork
- Tests are collected only from a package tree (
src/lib.cairo
as an entrypoint) andtests
folder:- If there is a
lib.cairo
file intests
folder, then it is treated as an entrypoint to thetests
package from which tests are collected - Otherwise, all test files matching
tests/*.cairo
regex are treated as modules and added to a single virtuallib.cairo
, which is treated as described above
- If there is a
account add
command for importing accounts to the accounts fileaccount create
command for creating openzeppelin accounts with starkli-style keystoreaccount deploy
