Some quick updates:

Thanks @furnic for the tip regarding mint_to. I’ll update the post to include that once it’s possible to edit posts ([Meta] Ability to edit posts).

Also, @fuel had a good post about the ability to store strings in Sway:

How to save strings in the storage of dapp?

Hello everyone! In an attempt to implement a token contract on fuel I forked swayswap’s token contract and noticed that swayswap’s token doesn’t support the same fields like name, symbol, and decimals. Then in one of my previous topics @david sent me a topic with src-20 fungible token standard, but there is no name, symbol implementation too… And today I decided to figure out how I can store strings in the storage. In the progress of my research I found some solutions, let’s take a closer l…

@fuel’s current token implementation (https://github.com/sway-gang/fuel-token-standard/blob/master/src/main.sw) currently uses fixed-length character arrays for the name & symbol elements. This is probably the best way to implement these strings today, however I believe the final token standard should use dynamic-length strings (which aren’t available yet).
