There is a bunch of utility functions you can use:

* [$bigint](https://github.com/0xweb-org/dequanto/blob/master/src/utils/%24bigint.ts)  - `bigint` helper to convert `wei`, `gwei`, `ether` ;  float multiplying and division
* [$date](https://github.com/0xweb-org/dequanto/blob/master/src/utils/%24date.ts) - lots of date methods - replaces `moment.js` and `date.js` libraries
* [$require](https://github.com/0xweb-org/dequanto/blob/master/src/utils/%24require.ts) - assertion utilities. *You should use assertions in the blockchain development much more often, as any small error can lead to huge losses*
* *...*

Please, go through the code, maybe you'll find something for your needs.
