Ethereum

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.
