Alta Raises US$47.5 Million Series a to Build Blockchain Infrastructure

Alta Secures $47.5 Million

Financial infrastructure startup Alta raised US$47.5 million in a Series A funding round, Fintech News Singapore reported on November 11, 2026, lifting its cumulative funding to US$80 million.

The Tech TL;DR:

• Alta closed a US$47.5 million Series A round led by Index Ventures on November 10, 2026, bringing its total capital raised to US$80 million.
• The company is building a private Layer 1 blockchain utilising recursive zero-knowledge cryptography to satisfy institutional privacy and regulatory mandates.
• Airwallex is serving as an investor and launch partner to connect the network to fiat payment rails across 200 countries and 90 currencies.

Index Ventures led the financing round alongside participants GV, Blackbird Ventures, Square Peg, and Capital 49, according to Fintech News Singapore. The fresh capital builds on US$32.5 million in earlier seed financing secured by the company, which previously operated under the name Metal through its legal entity Nexus Networks, Inc., venturecapitaltracker.com reported.

Building Private Blockchain Infrastructure

Alta is developing a Layer 1 blockchain architecture designed specifically around the privacy and compliance constraints of regulated financial institutions. Existing distributed ledgers fail to meet these stringent regulatory standards, according to company statements reported by Fintech News Singapore.

Existing blockchains aren’t designed for the privacy and compliance requirements of global financial institutions, said Loong Wang, Co-founder and CEO of Alta. We’re taking a fundamentally different approach, building privacy, programmable compliance, and identity and authorisation directly into the blockchain.

The network relies on recursive zero-knowledge cryptography to keep transaction balances, identities, and compliance policies hidden while cryptographically verifying that specific transfer rules are satisfied. The policy-controls design lets institutions enforce rules over recipients, jurisdictions, assets, amounts and source of funds directly during settlement rather than treating compliance as a separate delayed step.

Targeting Idle Institutional Cash

Alta’s initial product offering targets global liquidity management by focusing on capital trapped in prefunded accounts. The company estimates that businesses maintain approximately US$4 trillion in such accounts worldwide.

Utilising tokenised assets, the planned liquidity product aims to enable just-in-time funding and efficient foreign exchange transactions. This infrastructure is intended to let businesses move instantly into and out of yield-bearing tokenised assets to earn interest on otherwise idle capital, Fintech News Singapore reported.

Catherine Porter, Co-founder and President of Alta, stated that financial institutions require trustworthy infrastructure with explicit controls over money flows and sensitive data. She added that this trust becomes increasingly vital as autonomous agents handle more financial decisions.

Airwallex Uses Alta Blockchain to Connect Global Fiat Rails

Global payments provider Airwallex has chosen to build on Alta’s blockchain infrastructure as an affiliated design and launch partner. The collaboration supports stablecoin pay-ins and pay-outs while connecting the network to local fiat payment rails across 200 countries and 90 currencies, according to Fintech News Singapore.

Financial institutions need blockchain infrastructure that is private, neutral, regulated, and connected to global fiat rails, said Jack Zhang, Co-founder of Alta and CEO of Airwallex.

According to Alta’s payments documentation, destination partners handle currency conversion and local delivery, meaning that final deposit times depend on local payment networks and conversion partners rather than instantaneous on-chain settlement alone. Alta intends to establish neutral infrastructure for banks and payment providers, though independent production volume and a substantial roster of unaffiliated paying financial institutions remain unproven.
