Security
Smart contract security is a top priority for those working on Aura Finance. All reasonable precautions must be taken to ensure the protocol is safe to use. Below is a list of some of the things we believe make smart contract systems secure.
Chainalysis's Proactive Incident Response
Aura has partnered up with @chainalysis to adopt an Incident Response Plan for the protocol. The IRP adds an extra layer of security on top of well-developed code and audits, Aura will be able to deter hackers and have an asset recovery plan in potential events.
Audits

Bug bounties
External bug bounties are essential for projects. Aura has placed a $1m critical bug bounty payout on Immunefi.
Internal processes
Codebase
Some practices employed on Aura Finance smart contract repositories:
protected
masterbranch with mandatory peer reviews and passing CI (including linting, compiling, and testing)>98% code coverage (using coveralls) and comprehensive integration tests
Strict linting rules
Code commented using the Natspec standard
Fork testing
Fork testing is helps simulate contract deployments and functionality in a live environment, accounting for external dependencies. Aura comprehensively tests deployments using fork tests.
Internal auditing
Developers know their code best, and dedicated time has been taken to manually review all code in the system.
