About Squads:

Since 2021, we’ve built products and APIs that unlock the benefits of modern money.

We began with Squads Protocol, the autonomous finance layer built on Solana. Secured by Solana’s permissionless ledger, Squads Protocol enables programmable payments, 24/7 USD liquidity, competitive yields and security enforced by deterministic code, not corporate promises.

The new financial stack is being built on blockchains, powered by tokenized assets, and designed for a world where value moves as freely as information. We build on Squads Protocol to bring this stack to every developer, business, and individual.

Stablecoins were once a niche experiment. Today, they’re one of the fastest-growing technologies in history. The question isn’t if stablecoins consume every aspect of finance, but when. We’re here to compress that timeline. Join us.

About the Product:

Altitude, our next-generation USD account designed for modern global businesses. Altitude enables companies to store, earn, and move dollars globally—without banks, borders, or friction—by combining stablecoin rails, fiat connectivity, and programmable treasury infrastructure into a single seamless experience.
