Alta raises $47.5M Series A to build a compliance-first blockchain for banks

Banks that want to move money on a blockchain already have plenty of choices. Ethereum, Solana and Avalanche are all available and actively courting financial firms.

Alta thinks they need one more. The startup has raised $47.5 million in a Series A round to build a Layer 1 blockchain designed around compliance from the ground up.

Index Ventures led the round, which Alta announced on Tuesday. The company did not disclose its valuation.

Who’s writing the checks

Index Ventures had company at the table. GV, the venture arm formerly known as Google Ventures, joined the round. So did Blackbird Ventures, Square Peg and Capital49.

The Series A follows a $32.5 million seed round. Airwallex, the Australian fintech competing with Stripe and others in payments, was the primary backer of that earlier round, with Capital49 also participating.

Add the two rounds together and Alta has now raised approximately $80 million in total.

What Alta is actually building

Alta’s pitch centers on a plug-and-play compliance layer. Customers can use it to confirm that the transactions they process line up with rules and regulations in any jurisdiction.

The company describes this as programmable compliance, with policy enforcement happening automatically at the protocol level. Rather than checking rules after a transaction happens, the chain itself is designed to apply them as part of processing.

Alta pairs that with privacy controls, a feature institutions tend to care about deeply. The chain is also built to connect to real-world payment rails. Alta says it supports payments across more than 200 countries and 90 currencies.

The target use cases are distinctly institutional:

• Tokenized deposits, meaning bank deposits represented as digital tokens on a blockchain
• Real-time foreign exchange, converting between currencies without the usual settlement lag
• Cross-border payments, the slow and expensive corner of finance that crypto has long promised to fix
• Integrated yield systems, letting money earn a return while it sits on the network

The founders behind it

Alta was co-founded by Loong Wang and Catherine Porter. Wang brings a background in crypto startups.

Porter is a former Meta executive who worked on the social media giant’s crypto initiatives.

Why another blockchain, and why now

Alta is betting that speed and cost are not the main barriers for banks. Compliance is.

Institutions using general-purpose networks typically have to bolt compliance tools on top. Alta’s approach flips the order, making compliance a native layer rather than an add-on.

The Airwallex connection is worth noting here. A payments company with global reach backing the seed round gives Alta a clear line of sight to how cross-border money movement works in practice, and where it breaks.
