Hi! Thanks for the PR and sorry for the late reply.

Although your changes were quite small I don't understand them properly, especially the useMemo and yield.

For now I just changed the default IPFS gateway to "https://w3s.link/ipfs/"
i also copied your code quality improvement of adding the tokenIconUri as a useEffect hook

I'll leave this PR open to maybe in the future futher investigate having IPFS fallbacks

• Sorry also for the late reply

• This was a quick fix tried not to change much. I used useMemo because the second useEffect that depends on ipfsGateways causes re-render without it. The getIpfsGateway is just a generator, it just yields the first ipfs gateway url that's tested to be accessible.

• If it works please do ignore this PR, w3s was reliable on my previous tests even if it was pinned using Pinata, hopefully it stays that way. 😀
