Dev Journal — Building a Non-Custodial Token Tool on Solana

Day 2

Worked on the token creation flow.

built /api/create-token
backend prepares transactions
frontend signs via wallet (Phantom)

Why
I wanted to keep everything non-custodial.

Problem
Where does signing actually happen?

At first I was mixing things:

some logic frontend
some backend

It got messy fast.

Decision
Backend builds → wallet signs → that’s it.

No exceptions.
