According to Co-founder @immutable Robbie Ferguson:

A quick update: @immutable has no exposure to Silvergate or SVB. We have more than A$280M in the bank (predominantly in USD), and do not use financial leverage. Stay safe out there - and keep building. The infrastructure we build today will form the basis of digital property for billions of people, and players will keep on playing. Let’s make sure it’s built on an open ecosystem owned by players.
