+# Sweepbase Crypto Cards Dataset
+
+Open dataset of **143 cryptocurrency debit and credit cards** that can be ordered as of September 2026:
+fees, limits, cashback, custody model, card network, regional availability and top-up methods.
+
+Maintained by [Sweepbase](https://sweepbase.net), an independent crypto-card comparison site.
+Rows are checked against the issuers' own documents. Cards that have closed to new applicants
+and cards that were announced but never issued are not in this file.
+
+## Files
+
+- `sweepbase-crypto-cards.csv`: primary format, 24 columns, UTF-8.
+- `sweepbase-crypto-cards.json`: identical rows, JSON array.
+- `metadata.json`: row count, SHA-256 hashes, generation date.

+
+## Schema
+
+All 24 columns, in file order. Every value is a string; an empty string means "not established", not "no".
+
+| Column | Notes |
+|---|---|
+| `url` | Page for this card on sweepbase.net; cite this |
+| `Card Service` | Official product name |
+| `Card Type` | Opens with `Virtual`, `Physical` or `Virtual + Physical`; some rows continue in prose |
+| `Visa or Mastercard` | Card network and tier |
+| `Custody` | Opens with `Custodial`, `Self-custody`, `Non-custodial` or `Hybrid custody`; some rows continue in prose |
+| `Website URL` | Official product page |
+| `Card Issuance Fee` | Local currency or `Free` |
+| `Annual Fee` | Local currency or `Free` |
+| `FX Fee` | Cross-currency fee |

+| `Daily Spending Limit` | Spending limits as published |
+| `Cashback` | Rate and the token it is paid in |
+| `Main Page Cashback` | Short cashback label |
+| `APR/Investing/Vault` | Yield, in prose. `Yes, on the spendable balance` / `Yes, vault-linked` = the balance the card spends earns; `Not on the card balance` = yield sits in a separate product; `Unclear:` = the issuer does not say which balance earns |
+| `Sign-up Bonus` | Welcome offer, short form |
+| `Welcome Bonus` | Full bonus terms |
+| `KYC` | Required, optional or tiered |
+| `Non-KYC` | Whether a tier without KYC exists |
+| `Regions KYC Available` | Where the card can be obtained, by region |
+| `Countries Available` | Country list where the issuer publishes one, otherwise prose, often with exclusions |
+| `Mobile Pay` | Apple Pay, Google Pay and similar |
+| `Top-up Methods` | Supported assets and funding methods |
