Change my mind:

ERC-20 should have enforced 18 decimals.

Projects gain little value from setting a different number of decimals, but they impose technical debt on the ecosystem by forcing developers to handle multiple decimal systems.

`decimals` is absolutely the worst part of the erc20 spec:

0) could be any number vs just being 18
1) is optional
2) doesn't have to be immutable

A valid ERC20 contract can return `decimals` as 4 today, then as 6 tomorrow.

Biggest pain when a partner needs <18 decimal support — lot bigger task than one would assume

I may never have agreed with anything more. Everything I've done with DeFi has had added complexity due to needing to check + verify token decimals.

This would have simplified things for developers for sure. 

For those that don't know - the decimals() function is actually an optional part to the ERC-20 standard. So you can have a valid ERC-20 that doesn't return decimals at all.

😂😂😂😂 #true currently having 18/14/12 in one project this is driving me crazy
