Alta, a Layer 1 blockchain startup formerly known as Metal, closed a $47.5 million Series A led by Index Ventures to build a chain with compliance rules enforced at the protocol level. Including its earlier $32.5 million seed round, the company reports roughly $80 million in total funding, though sources differ on the seed round's role and lead investor.

Story Updates
- Updated Nov 10, 2026, 02:59 PM: Alta's Series A is now reported at $47.5M, with Airwallex's seed role and the 200-country payment claim detailed.
The Round and Its Backers
Alta has closed a $47.5 million Series A led by Index Ventures, according to the company's announcement on X, which rounded the figure up to $48 million. GV, Blackbird Ventures, Square Peg and Capital49 also participated. Alta did not disclose its valuation.
The round follows a $32.5 million seed round. Crypto Briefing reports that Australian payments company Airwallex was the primary backer of that seed, with Capital49 also participating. Adding both rounds, Crypto Briefing puts Alta's total funding at approximately $80 million.
A Chain Built Around Compliance
Alta is developing a Layer 1 blockchain for financial institutions, and its central claim is that compliance, rather than speed or cost, is the main obstacle banks face on public networks. Alta calls its approach programmable compliance: rules travel with the transaction and are enforced as it moves, rather than checked after settlement, which is how institutions typically apply add-on tools to general-purpose networks such as Ethereum, Solana or Avalanche.
Privacy is handled through recursive zero-knowledge proofs, which let a party demonstrate that a transaction follows the rules without exposing every underlying detail. The chain is also designed to support stablecoin payments and tokenized assets. Alta says it aims to support cross-border payments across roughly 200 countries and 90 currencies; neither outlet reports independent verification of that coverage.
Where the Sources Diverge
The reports differ on Airwallex's role. Crypto Briefing describes it as the primary backer of the seed round. The Defiant frames Airwallex's involvement as a plan to connect the network to local payment rails, which points to a commercial or integration relationship. The sources emphasize different parts of the same relationship, and neither gives enough detail to confirm the terms of Airwallex's stake or its integration timeline.
Crypto Briefing also notes that Airwallex is both an investor and a key distribution channel. That arrangement gives Alta a potential path to transaction volume from an existing cross-border business customer base, but reliance on a single distribution partner also creates concentration risk if priorities shift.
Founders and Competitive Position
Alta was co-founded by Loong Wang, who serves as CEO, and Catherine Porter. Crypto Briefing describes both as having notable crypto backgrounds. The rebrand from Metal to Alta signals a sharper focus on institutional clients.
Ethereum, Solana and Avalanche already court financial firms, so Alta is entering a market with established competitors. Its pitch depends on whether banks treat compliance as a native protocol feature and whether the chain's privacy controls satisfy regulators. Crypto Briefing says the company now has the resources to test that design; the next step is evidence that institutions use it.
Why It Matters
For Traders
Alta is a private startup with no announced token, so the round offers no direct trading exposure, though it may signal bank interest in compliant chains.
For Investors
Institutional-focused Layer 1s with compliance built in could find a market if banks prefer protocol-level controls over bolt-on tools.
For Builders
Developers building for regulated finance should watch whether protocol-native compliance becomes a standard expectation on new chains.
