Farcaster Pro update

A) The limited edition NFT will be airdropped early next week to the first 10,000 pro subscribers. It will appear in your in-app Farcaster wallet. You will be able to send it to another wallet.

B) We have 3 Pro subscriber benefits that will likely ship the week of June 16th:

1. 10K character casts

2. 4 embeds — originally it was going to be 4 images but we've expanded it to 4 embeds including images, videos, URLs, CAs and mini apps.

3. A new, previously announced feature: profile banner images

C) We'll have FIPs up later today for the proposed protocol implementations.

D) We're finalizing the Pro subscription contract on Base. It will accept USDC and allow for monthly or yearly subscriptions permissionlessly at the protocol, i.e. any app can allow Pro subscriptions.

There will be some clean up work to do in the Farcaster app to reflect monthly subscriptions. We don't have immediately plans to offer UX for monthly in-app but people will be able to build mini apps that do this.
