This is only relevant if you run your own hubs. You will need to take action to read and write to Farcaster.

If you use Neynar or other API providers, you will not need to take action.

Phase 1 - Genesis Block (Mar 21)

Snapchain will start producing blocks and ingesting historical data. It will be slowly catching up to the state of hubs.

Hubs Must use to read and write to the network
Snapchain Cannot use to read and write to the network reliably.
Can set up a read node for testing purposes.

Recommendation for devs: keep using hubs.

Phase 2 - Data Backfill Complete / Migration Begins (Apr 4th)

Snapchain will have finished ingesting all live data from the network. Warpcast will replay all messages from hubs onto Snapchain.

Hubs Can use to read and write to the network
Snapchain Can use to read and write to the network.

Recommendation for devs: set up a snapchain node and try migrating your app and give us feedback if things aren’t working.

Phase 3 - Mainnet Launch (Apr 15th)

Snapchain is now the source of truth and hubs will start falling behind. Data sent to hubs will not automatically be replayed on snapchain and may be lost when we go into phase 5.
