vouchers

Organize your Bitcoin vouchers on your Solid pod. A voucher is a funded key recorded as a TXO URI (txo:<network>:<txid>:<vout>?amount=<sats>&key=<privkey>); the app derives its taproot address, checks balance + spent status via mempool.space, and can sweep funds.

Ported from [melvincarvalho/gamestr-adjacent Voucher Pool] — the proven Bitcoin crypto (BIP340/341/86 taproot, transaction building/signing/broadcast) is kept verbatim; only storage and the app shell were adapted for the suite.

⚠️ Security — keys are private

Voucher data contains private keys. This build stores it owner-only at <pod>/private/vouchers/voucher-data.jsonld (not /public/), and reads it with authenticated requests. Keep it that way. Networks include testnet3/4 and mainnet (btc) — treat mainnet keys accordingly.

Data model

<pod>/private/vouchers/voucher-data.jsonld
{ "@context": { "schema": "https://schema.org/" },
  "@type": "schema:CreativeWork", "schema:additionalType": "VoucherPool",
  "schema:itemListElement": [
    { "@type": "schema:ListItem",
      "schema:identifier": "txo:tbtc4:<txid>:<vout>?amount=<sats>&key=<privkey>",
      "schema:address": "tb1p…", "schema:status": "unspent",
      "schema:dateCreated": "…" } ] }

Notes

• Auth uses nip98 (NIP-98 HTTP auth) for pod read/write, as in the original — i.e. it authenticates with a nostr key, not the Solid OIDC login pill.
• Balance / spent / sweep use the public mempool.space APIs (no key needed).
• Crypto deps load at runtime from esm.sh (txo_parser, @noble/curves, nip98).
