Being part of the team that moves Starknet forward is a great honor, but it also means that its your phone that rings when there is any outage. And as Starknet usage surged, we tackled edge cases that caused the phone to ring quite a few times over 09.10-15.10 And each time it

1/ Bitcoin doesn’t change. But what you can do with it just did. From the June 2024 announcement that Starknet would scale Bitcoin, to the product rollouts of March 2025, the path has been clear. BTCFi on Starknet is where that momentum now leads 🧵
