To understand the relationship - 0xWeb uses dequanto as its dependency, and not vice-versa. Dequanto is a standalone library you can use in any blockchain-related project.
Install
π Distributed as Source Code
Though we have published the npm package - dequanto. But we advise using dequanto as a git submodule.
If you have installed via npm, the path would be "node_modules/dequanto/src/*
Configure
There is a bunch of things in configuration to be loaded at application start - like Node URLs, API Keys. The most simple is to use 0xweb to create a default config file, which you can edit
Load that configuration on startup
It is safe to call the method multiple time, but enough only once.
