Airwallex is an early design partner connecting its payment network with Alta’s blockchain. The announced collaboration covers stablecoin pay-ins and payouts and connections to local fiat networks across 200 countries and 90 currencies. Alta said its first product would address business liquidity through tokenized assets, just-in-time funding, foreign exchange, and movement between idle cash and yield-bearing assets.⁠[4]

Alta uses recursive zero-knowledge proofs for compliance verification, aiming to validate transaction conditions without exposing accounts, transactions, identities or policies, while allowing selective authorized disclosure. Its design covers assets and services including stablecoins, money market funds, foreign exchange and credit.⁠[1]

Institutions can define counterparties, jurisdictions, assets, amounts, source-of-funds requirements and approvals, and connect existing screening providers. Settlement must satisfy sending and receiving policies; selected transaction records and evidence can be shared with authorized counterparties, auditors or regulators.⁠[7]

The cross-border design brings the sending currency into stablecoin settlement, with destination partners handling conversion and local delivery. Use cases include international transfers, supplier payments, payroll and intercompany funding. Alta describes its own settlement as real-time and continuous, while bank-account delivery depends on conversion, destination partners and local payment networks. Available routes depend on currency and partner coverage.⁠[8]

The treasury design includes intercompany transfers, combined fiat and stablecoin management, tokenized money market funds for idle balances, and rules for collections and recurring payments. It also includes AI demand forecasts and suggested transfers for approval or automation. Custody may remain with the institution or an external provider, with transfer authority determined by the chosen arrangement.⁠[9]

FX liquidity partners supply the other side of exchanges through stablecoin rails, with conversion at settlement. Both sides complete together through an atomic swap or neither completes. Rates depend on the currency pair, transaction size and market conditions at execution. Received assets can be held, transferred, or converted into local bank money through payout partners.⁠[10]

The embedded-finance design lets institutions combine stablecoin wallets, payments, conversion, card spending and tokenized investments within their own interfaces. Customers need not manage a separate wallet application. Signing and authorization depend on custody choices, which may include customer self-custody, an existing custodian or an external provider. Availability remains subject to eligibility and market conditions.⁠[11]

The yield design connects on-chain providers and tokenized money market funds for institutional operating balances or customer-facing products. Institutions select investments that fit their risk and redemption requirements and control allocations. When payments fall due, they can manually or automatically redeem the required portion while leaving the remainder invested.⁠[12]

The agent-payment design allows software agents to buy data, software and other services or initiate funding transfers within institutional authority. Institutions set amounts, recipients, assets and approval requirements and may change or revoke authority at any time. Permitted transactions can execute automatically; those requiring additional approval must receive it first. Transaction outcomes and policy evidence remain available for review.⁠[13]

In his November 10, 2026 founder essay, Loong Wang identified real-time FX, cross-border payments and yield allocation as initial development areas, with longer-term aims covering investment, credit and trade. The stated objectives include reducing prefunding, improving settlement efficiency and embedding privacy and compliance throughout transactions.⁠[14]
