Magic

Magic builds the infrastructure that sits between enterprises and the blockchain. Founded in 2018, the company is generally credited with inventing the embedded wallet: a way for a firm to provision non-custodial wallets inside its own product, trigger onchain actions and satisfy compliance obligations through a single production-ready API. Seven years on, that bet has scaled to more than 50 million wallets across 18,000 applications, with a developer community of some 200,000.

The engineering problem is one of consequence rather than novelty. Embedding key management, account abstraction, policy enforcement and transaction orchestration into the systems of banks, gaming platforms, publishers and e-commerce firms demands work at the intersection of cryptography, distributed systems and enterprise reliability. Magic's platform is built for that regime - production-grade, compliance-aware and deployed across verticals from fintech to media. Backers include PayPal Ventures, Lightspeed, Placeholder and SV Angel.

The company is now extending its thesis beyond wallets. Newton Protocol is described as the first policy protocol designed to govern AI agents and their assets - entities that require more compliance and composability than smart contracts alone can express. It is a first-of-its-kind effort to make autonomous systems auditable and controllable, and it demands the same rigour that has defined Magic's work in non-custodial infrastructure since 2018.

Roles here suit engineers who are drawn to hard, unglamorous problems at scale: cryptographic key systems, policy and compliance layers, developer-facing APIs and the operational discipline of infrastructure that cannot fail quietly. The remit is broad, the standards are high, and the work reaches tens of millions of end users.
