Readme

Tealer

Tealer is a static analyzer for Teal code. It parses the Teal program, and builds its CFG. The analyzer comes with a set of vulnerabilities detectors and printers allowing to quickly review the contracts. In addition, tealer allows for custom path discovery through regular expression, and can be configured to follow the group information of the application.

Usage
- Detectors: Vulnerabilities detectors
- Printers: Visual information
- Regular expression: Regular expression engine
How to install
Group configuration

Usage

To detect vulnerabilities

tealer detect --contracts file.teal

To run a printer

tealer print  --contracts file.teal

To run the regular expression engine

tealer regex  --contracts file.teal

For additional configuration, see the Usage documentation.

Detectors

Num	Detector	What it detects	Applies To	Impact	Confidence
1	`is-deletable`	Deletable Applications	Stateful	High	High
2	`is-updatable`	Upgradable Applications	Stateful	High	High
3	`unprotected-deletable`	Unprotected Deletable Applications	Stateful	High	High
4	`unprotected-updatable`	Unprotected Upgradable Applications	Stateful	High	High
5	`group-size-check`	Usage of absolute indexes without validating GroupSize	Stateless, Stateful	High	High
6	`can-close-account`	Missing CloseRemainderTo field Validation	Stateless	High	High
7	`can-close-asset`	Missing AssetCloseTo Field Validation	Stateless	High	High
8	`missing-fee-check`	Missing Fee Field Validation	Stateless	High	High
9	`rekey-to`	Rekeyable Logic Signatures	Stateless	High	High
10	`constant-gtxn`	Unoptimized Gtxn	Stateless	Optimization	High
11	`self-access`	Unoptimized self access	Stateless	Optimization	High
12	`sender-access`	Unoptimized Gtxn	Stateless	Optimization	High

For more information, see

The Detector Documentation for information on each detector
The Detection Selection to run only selected detectors. By default, all the detectors are ran.

Printers

Num	Printer	What it prints
1	`call-graph`	Export the call graph of contract to a dot file
2	`cfg`	Export the CFG of entire contract
3	`human-summary`	Print a human-readable summary of the contract
4	`subroutine-cfg`	Export the CFG of each subroutine
5	`transaction-context`	Output possible values of GroupIndices, GroupSize

Printers output dot files. Use xdot to open the files (sudo apt install xdot).

Regular expression

Tealer can detect if there is a path between a given label and a set of instruction using the regex subcommand: tealer regex regex.txt --contracts file.teal.

The Regular expression file must be on the form:

label =&gt;
  ins1
  ins2

If there is a match, tealer will generate a DOT file with the graph.

For an example, run tealer regex tests/regex/regex.txt --contract tests/regex/vote_approval.teal, with:

Which will generate regex_result.dot.

How to install

pip3 install tealer

Using Git

git clone https://github.com/crytic/tealer.git &amp;&amp; cd tealer
make dev

Group configuration

To help tealer reasons about applications that are meant to be run in a group of transaction, the user can provide the group information through a configuration file:

See the ANS configuration example
See Lightweight group information specification discussion.

The file format is still in development, and it is likely to evolve in the future
