Sailfish

This repository contains the code and the experimental data for the IEEE S&P'22 paper: SAILFISH: Vetting Smart Contract State-Inconsistency Bugs in Seconds

Installing Sailfish

The easiest way to get started is to use our pre-built docker image: docker pull holmessherlock/sailfish:latest. However, if you want to build the tool yourself, follow the steps in docker/Dockerfile.

Running Sailfish

If you are using the docker image, spawn a container: docker run -it holmessherlock/sailfish:latest bash. Navigate to the sailfish/code/static_analysis/analysis directory.

Run test-cases

python contractlint.py -c ../../test_cases/reentrancy/mutex_fp_prunning_non_reentrant.sol -o <path/to/output-dir> -r range -p DAO,TOD -oo -sv cvc4

python contractlint.py -c ../../test_cases/reentrancy/mutex_fp_prunning_non_reentrant.sol -o <path/to/output-dir> -r havoc -p DAO,TOD -oo -sv cvc4

Symbolic executor

Run the symbolic executor standalone

To run the symbolic executor, you need a compatible JSON file. Check the input JSON specifications for detailed syntax. If your JSON file comes from range analysis, run the translator to get a compatible JSON file before you run the tool.

./reentrancy | tod | tod-complement \
	<--file "/path/to/file.json"|--raw "json string"> \
	[--attack none|havoc|range|path] \
	[--solver z3|cvc4|yices] \
	[--beb <non-negative integer>] \
	[--verbose] \
	[--debug]

--file: specify the json file path to read in

--raw: specify the json raw string to read in

--attack (default: none): specify the attack mode

--solver (default: cvc4): specify the backend solver to use, you may need to configure the solver (see here; for cvc4, the 1.7 version is recommended)

--beb (default: 0/strict mode, 10/tolerant mode): specify the block execution bound (maximum number of times a block can be executed), if set to integer <=0, no bound will be applied. <u>For tolerant mode, 10 is recommended to eliminate potential soundness problem (see known issues).</u>
