Alta has raised $80 million in total funding, including a $47.5 million Series A led by Index Ventures, to develop blockchain infrastructure designed for regulated financial institutions. GV, Blackbird Ventures, Square Peg and Capital 49 participated in the Series A. The total also includes $32.5 million in previous seed financing.
Alta is building infrastructure that allows financial assets and products to move globally and programmatically, with privacy, compliance, identity and authorization controls incorporated into the blockchain itself.
Its architecture uses recursive zero-knowledge cryptography to verify that transactions meet required rules while keeping balances, transaction details, identities and compliance policies private. The company intends the system to support activity across assets, blockchain networks and jurisdictions.
Airwallex has selected Alta as a technology partner, connecting its global payments infrastructure with Alta’s blockchain. The collaboration will support stablecoin pay-ins and payouts, alongside connectivity to local fiat payment networks across 200 countries and 90 currencies.
Alta positions its infrastructure as a neutral foundation that banks, payment providers and other financial institutions can use to develop services.
Its first product will focus on corporate liquidity management. Built around tokenized assets, the offering is intended to enable just-in-time funding, improve foreign exchange efficiency and reduce the cash businesses keep in prefunded accounts.
The product will also allow businesses to move into and out of yield-bearing tokenized assets, helping them earn interest on capital that would otherwise remain idle. Alta cited an estimated $4 trillion held in prefunded accounts globally as evidence of the opportunity to improve capital efficiency.
The company’s founders include CEO Loong Wang, President Catherine Porter and Airwallex Co-Founder and CEO Jack Zhang. They identified institutional controls and connectivity as requirements for expanding blockchain-based finance, including transactions initiated by AI agents.
Alta will use the funding to continue developing its blockchain, expand institutional partnerships and global financial connectivity, and grow its engineering and compliance teams.
KEY QUOTES
“Existing blockchains aren’t designed for the privacy and compliance requirements of global financial institutions. We’re taking a fundamentally different approach, building privacy, programmable compliance, and identity and authorization directly into the blockchain. This will enable money and assets to move instantly, globally, and securely, whether it’s a bank settling a transaction or an AI agent making a payment.”
Loong Wang, Co-Founder And CEO Of Alta
“Technology alone won’t be enough to modernize global finance. Financial institutions need infrastructure they can trust, with clear controls over who they’re transacting with, where money can move, and how sensitive information is protected. As AI agents increasingly make financial decisions and execute transactions, that trust becomes even more critical. Privacy, compliance, and accountability just aren’t barriers to innovation – they’re what will allow it to scale.”
Catherine Porter, Co-Founder And President Of Alta
“With the rise of agentic banking and programmable payments, stablecoins are becoming an important vector for settlement. Financial institutions need blockchain infrastructure that is private, neutral, regulated, and connected to global fiat rails. Alta is building exactly that. We’re proud to be an early design partner and help Alta deliver onchain finance at institutional scale.”
Jack Zhang, Co-Founder Of Alta And Co-Founder And CEO Of Airwallex
“Loong is the sort of technologist you only meet a few times in a career. After a major fintech exit from his first company, he went on to run the largest supercomputing calculation in history at its time, then discovered a cancer drug now in human trials. With Catherine’s exceptional track record of bringing industry leaders to the table and Jack’s understanding of the problem space, this is a team we had to back.”
Jan Hammer, Partner At Index Ventures
“The Alta founders have successfully built and scaled multi-billion-dollar technology and financial infrastructure businesses, and understand how to de-risk complex institutional execution. We have been impressed with their combination of deep-tech blockchain engineering, institutional go-to-market knowledge, and vision for scale, and we look forward to supporting them in their mission to reimagine financial infrastructure at its core.”
Tom Hulme, Managing Partner At GV
“Stablecoins solved speed. Alta is solving trust, with privacy by default and compliance written into the settlement itself, so the institutions that hold the world’s money can finally use them. We’ve known Loong and Jack for years, and watching two of Melbourne’s best join forces, with Airwallex anchoring Alta from day one, is the kind of moment this job is for. Catherine is more than their match. She built the enterprise stablecoin playbook at Meta before most people knew one existed, and together she and Loong are the most complete founding team we’ve seen in a long time.”
Michael Tolo, General Partner At Blackbird Ventures
“We are thrilled to be participating in Alta’s Series A. Alta brings a combination of a world class team with incredible domain expertise solving an important problem at exactly the right time. We are so excited to have the opportunity to back Loong and Catherine and their team early in their journey.”
Paul Bassat, Co-Founder And Partner At Square Peg
“We have backed Alta since its founding, and what stands out about this team is how fast they turn conviction into working infrastructure. Global finance won’t move onchain without institutional-grade readiness, and that’s exactly what Alta is demonstrating, one partner at a time.”
Chris Cheng, Managing Director At Capital 49
