Higher approval and lower cost on every transaction
For every payment, Tuna picks the acquirer based on risk and on the performance of each connection. Rules change in the Console, with no new integration.
Build custom payment strategies
With Tuna, you connect multiple providers and anti-fraud solutions through a single integration. Set dynamic rules by context, run A/B tests between acquirers and configure payment retries.
Decision layers between authorization and settlement
Each layer is configurable by context — method, card brand, BIN, amount, country, seller, channel — and runs in milliseconds within the authorization flow.
Transaction attributes are read before the route is chosen.
Orchestrated anti-fraud, with 3DS applied only where the approval gain outweighs the friction.
Balances cost and approval on every transaction and instantly falls back to the second option on failure.
Split, payouts, reconciliation and reports, all from the same transaction.
Build custom payment flows for your business model
Sooo many payment and anti-fraud providers in a single integration
Acquirers, Pix and boleto providers, anti-fraud and biometrics are available for routing with no new integration. Enabling, testing or replacing a provider is configured directly in the Console.

In-house tokenization: smaller PCI scope and portable saved cards
Sensitive data is tokenized in Tuna Proxy and comes back as a token. Your PCI scope shrinks, you are no longer tied to a single vault provider, and saved cards stay portable across acquirers.
Rule changes without a dev backlog
Business, CS and finance teams change rules, test acquirers and track cost and approval on the same dashboard.
