Introduction to N-SCOSS Rating

To provide reference on Nsure’s underwriting and its adjacent approach on our rating mechanism, we are here to introduce Nsure Smart Contract Overall Security Score (N-SCOSS) to help participants better understanding the underlying risk of each project listed on Nsure.
You may have already noticed the Security Rating assigned to each project on our Alpha Underwriting section. The grading of this Security Rating is based on N-SCOSS.

I. Overview

Below is the exact formula for calculating N-SCOSS.

III. Five Pillars

Pillar One — History & Team

  • Project age
  • Past exploits (if any)
  • Team anonymity
  • Team experience in programming

Pillar Two — Exposure

  • Total value locked
  • Industry segment
  • Infrastructure

Pillar Three — Audit

  • Audit transparency and scope
  • Audit findings
  • Audit firm trust score
  • Other credits

Pillar Four — Code quality

  • Documentation
  • Test

Pillar Five — Developer Community

  • Bug bounty program
  • Issues raised on Github

IV.Future improvement

2. Data & Parameter calibration
Currently, we’ve been using data from reliable sources such as SlowMist Hack Zone, DeBank & DefiPulse, to mention some of the sources in the correlation study and parameter (weight) calibration. It is intended to have set up an automatic data feed into the rating model via external data aggregation, minimising manual interference. The purpose of doing so is to minimise centralised judgement and to make N-SCOSAS an auto-generated indicator on Nsure dashboard for users’ reference.
