I have closed another pull request that was created before RPC is available, apologies for that.

Changes:

• Added Reactive Mainnet information
• Fixed RPC url for Reactive Kopli Testnet
• Updated IPFS image to meet file size requirements

Chores:

• Gradle build successful
• Prettier

You successfully submitted a PR! Due to the amount of PRs coming in: we will only look at PRs that the CI is happy with. We can also not hold your hand getting the CI green - just look how others that where merged did it and RTFM. So as long as there is any CI check that reports an error - no human will look at this. You might be able to ask for some support after supporting the project - e.g. by sending funds to lists.eth. When you fixed things after a requested change - then you also need to (re-)request a review.
