Baanx primary sources — 2026-04-30

Project status in this pass

  • No canonical standalone whitepaper or litepaper surfaced.
  • The clearest current source of truth is the official API docs corpus, llms.txt, and the main site.

Primary-source snapshots

1) Main site

  • URL: https://www.baanx.com/
  • Key excerpt:
    • The homepage describes Baanx as “Digital Banking & Crypto Solutions” and says its technology enables self-custody transactions so users can buy, spend, and borrow against digital assets.
    • Visible homepage sections and copy highlight non-custodial debit cards, custodial debit cards, card acquiring, and borrowing.
    • The page also prominently features partner/customer testimonials from Visa, Mastercard, MetaMask, Ledger, Exodus, and 1inch, indicating strong emphasis on embedded partner card programs.

2) Docs introduction

  • URL: https://docs.baanx.com/guides/introduction
  • Key excerpt:
    • The introduction calls Baanx API a “multi-tenant gateway” that bridges cryptocurrency wallets with traditional card payments.
    • It explicitly presents OAuth 2.0 with PKCE, dual wallet models (custodial and non-custodial), physical/virtual cards, blockchain delegation, and consent management as first-class platform components.
    • The examples position Baanx for crypto wallet apps, DeFi platforms, neobanks, exchanges, and white-label third-party apps.

3) Docs llms.txt

  • URL: https://docs.baanx.com/llms.txt
  • Notes:
    • Enumerates a broad first-party API and docs surface: auth/login, OAuth, onboarding and KYC, consent management, card ordering/status/PIN/details/statements, blockchain delegation, internal/external/credit/reward wallets, transaction history, and related guides.
    • The breadth of the index is strong evidence that Baanx is operating a fairly complete wallet-and-card middleware stack rather than publishing a thin wrapper around a single product.

4) Card operations overview

  • URL: https://docs.baanx.com/guides/card/overview
  • Key excerpt:
    • The guide says the Card API provides end-to-end control over the card lifecycle from ordering and activation through management and transaction monitoring.
    • Sensitive operations use tokenized access patterns and hosted/iframe flows so partners can view card details or manage PINs without directly handling PCI-sensitive data.
    • The current guide says virtual cards are available now and physical-card support is “coming soon.”

5) Wallet-to-card linking

  • URL: https://docs.baanx.com/guides/wallet/custodial/card-linking
  • Key excerpt:
    • The guide shows custodial internal wallets can be linked to cards, with transaction funding determined by wallet priority.
    • It documents API endpoints for linking, unlinking, listing linked wallets, and updating priority order.
    • The examples show the platform can attempt multiple balances across wallets/currencies/networks when settling a card transaction.

6) Delegation overview

  • URL: https://docs.baanx.com/guides/delegation/overview
  • Key excerpt:
    • The delegation docs describe non-custodial wallet delegation for card payments, where users retain key custody but approve limited spending authority.
    • Supported wallet examples include MetaMask, WalletConnect, Coinbase Wallet, Phantom, Solflare, and Backpack.
    • Current docs name Linea, Ethereum, and Solana support, with EVM approvals and Solana delegation completed through separate backend finalization endpoints.

7) Credit-wallet API

  • URL: https://docs.baanx.com/api-reference/wallet/credit
  • Key excerpt:
    • The API reference defines a credit wallet that holds funds available for spending through the platform and returns balance, currency, withdrawability, and wallet type.
    • This suggests Baanx is not only orchestrating external spending approvals, but also exposing an internal wallet/ledger surface for partner applications.

Working conclusion

Baanx is best cataloged as crypto-to-card finance infrastructure: a middleware/control-plane vendor that combines onboarding, wallet custody options, delegation, card issuance and management, and internal balance surfaces into one partner-facing stack. The docs make it look much broader than a simple debit-card brand.
