Features:

• testing framework based on pytest
• property-based fuzzer
• deployments & mainnet interactions
• vulnerability and code quality detectors
• printers for extracting useful information from Solidity code
• static analysis framework for implementing custom detectors and printers
• Github actions for setting up Wake and running detectors
• language server (LSP)
• VS Code extension (Tools for Solidity)
• solc version manager

• Python (version 3.7 or higher)
• Rosetta must be enabled on Apple Silicon Macs

⚠️ Python 3.12 is experimentally supported.

via pip

pip3 install eth-wake

Wake documentation can be found here.

There you can also find a section on contributing.

See examples and documentation for more information.

Writing tests is as simple as:

from wake.testing import *
from pytypes.contracts.Counter import Counter

@default_chain.connect()
def test_counter():
    counter = Counter.deploy()
    assert counter.count() == 0

    counter.increment()
    assert counter.count() == 1

Fuzzer builds on top of the testing framework and allows efficient fuzz testing of Solidity smart contracts.

from wake.testing import *
from wake.testing.fuzzing import *
from pytypes.contracts.Counter import Counter

class CounterTest(FuzzTest):
    def pre_sequence(self) -> None:
        self.counter = Counter.deploy()
        self.count = 0

    @flow()
    def increment(self) -> None:
        self.counter.increment()
        self.count += 1

    @flow()
    def decrement(self) -> None:
        with may_revert(PanicCodeEnum.UNDERFLOW_OVERFLOW) as e:
            self.counter.decrement()

        if e.value is not None:
            assert self.count == 0
        else:
            self.count -= 1

    @invariant(period=10)
    def count(self) -> None:
        assert self.counter.count() == self.count

@default_chain.connect()
def test_counter():
    CounterTest().run(sequences_count=30, flows_count=100)

All vulnerability & code quality detectors can be run using:

wake detect all

A specific detector can be run using:

wake detect <detector-name>

See the documentation for a list of all detectors.

A specific printer can be run using:

wake print <printer-name>

See the documentation for a list of all printers.

Refer to the getting started guide for more information. Also check out wake_detectors and wake_printers for the implementation of built-in detectors and printers.

Wake implements an LSP server for Solidity. The only currently supported communication channel is TCP.

Wake LSP server can be run using:

wake lsp

Or with an optional --port argument (default 65432):

wake lsp --port 1234

All LSP server features can be found in the documentation.
