This Week in Custody #35
This Week in Custody is a newsletter covering technical and narrative developments in digital asset custody written for wallet engineers, digital asset operators, and security engineers.
I’m excited to share that Pine Street Labs, a company I have been building since the beginning of this year, is hiring software engineers. We’re building enterprise wallet software infrastructure to make it easier for on-chain businesses to support the networks and transactions that they need for their business functions.
