 - **Write thorough unit-tests.** An extensive test suite is crucial to build high-quality software. 
 - **Write [Slither](https://github.com/crytic/slither), [Echidna](https://github.com/crytic/echidna) and [Manticore](https://github.com/trailofbits/manticore) custom checks and properties.** Automated tools will help ensure your contract is secure. Review the rest of this guide to learn how to write efficient checks and properties.
-- **Use [crytic.io](https://crytic.io/).** Crytic integrates with Github, provides access to private Slither detectors, and runs custom property checks from Echidna.

 ## Static analysis
 
 The capabilities and design of the Slither static analysis framework has been described in blog posts ([1](https://blog.trailofbits.com/2018/10/19/slither-a-solidity-static-analysis-framework/), [2](https://blog.trailofbits.com/2019/05/27/slither-the-leading-static-analyzer-for-smart-contracts/)) and an [academic paper](https://github.com/trailofbits/publications/blob/master/papers/wetseb19.pdf).
