How do I get token name, symbol, and logo?

Question

Given a token, how do I determine the token's name, symbol, and logo?

Answer 1

SPL-Token's name, symbol, logo, and more can be retrieved today the following way:

1. Get associated Metaplex Metadata Account to check for Metadata
2. If no metadata exists, check legacy token-list from @solana/spl-token-registry

This means that first priority should be Metaplex Metadata, then @solana/spl-token-registry

Solflare's Unified Token List does this automatically if you want to use their source code.
