Description

In The Treewidth of Smart Contracts, the authors computed the treewidth of smart contracts, and showed that, in average, real-world contracts have a threewidth of 3.35 (intraprocedural) and 3.65 (interprocedural).

It would be interesting to add threewidth computation to Slither, and replay those results.

Contributor guide

Research direction
Study the treewidth algorithm from the referenced paper and explore Slither's intermediate representation (SlithIR) to compute treewidth of smart contract control flow graphs.
