2026-05-16Phase 3: Nostr identity derivation + wifistr service discoveryYour Name
- Add identity.c/h: HMAC-SHA512 derivation from nsec → npub, STA/AP MAC, SSID, AP IP - Add nostr_event.c/h: NIP-01 event serialization + Schnorr signing (BIP-340) - Add geohash.c/h: lat/lon to geohash encoding - Add wifistr.c/h: kind 38787 event builder + WebSocket publish to Nostr relays - Update config.c/h: nsec-based identity, Nostr relay/geo config, remove static SSID/IP - Replace custom mbedTLS wallet with nucula library (libsecp256k1) - Remove wallet.c/h, wallet_persist.c/h (replaced by nucula_lib component) - Verified on Board A: derived SSID, captive portal, payment, wallet, wifistr publish
2026-05-16Phase 3: on-device Cashu wallet with mbedTLS secp256k1 + SPIFFS persistence ↵Your Name
+ PSRAM - wallet.c/h: secp256k1 ECP primitives (hash_to_curve, scalar_mul, point_add) - wallet_persist.c/h: SPIFFS persistence with threshold-based write protection - Fee accounting for swap (input_fee_ppk from /v1/keysets) - Keyset fetch via /v1/keysets (586 bytes vs 21KB for /v1/keys) - Wallet API: GET /wallet, POST /wallet/swap, POST /wallet/send - Payment proofs auto-stored to wallet + persisted on SPIFFS - PSRAM enabled for large allocations (ESP32-S3 has 8MB) - Wallet init deferred to dedicated task (avoids sys_evt stack overflow) - Cashu proof ID buffer size fixed (66 hex chars, not 16) - HTTP client: added fetch_headers() call for proper response handling - persist_threshold_sats config parameter (default: 1 sat)
2026-05-16Fix captive portal detection on GrapheneOS + embed mint URL in portal HTMLYour Name
- Add esp_netif_set_dns_info() on AP interface so DHCP advertises AP as DNS server to clients (fixes captive portal on GrapheneOS) - Embed price and mint URL directly in portal HTML via server-side template substitution (no JavaScript fetch to :2121 needed) - Move supported mints section below the token input field - Add Playwright tests: no unresolved placeholders, embedded mint/price, DOM order verification (14/14 passing)
2026-05-16Unique SSID/IP per board + captive detection fix + mint list in portalYour Name
- Derive unique SSID (TollGate-{MAC4}{MAC5}) and AP IP (10.{b5}.{subnet}.1) from factory MAC — boards no longer conflict - Board A: TollGate-377C @ 10.55.85.1, Board B: TollGate-5050 @ 10.80.10.1 - Captive portal detection URIs return 200 with portal HTML (matching esp32-mesh working approach) instead of 302 redirect - Dynamic AP IP in portal HTML via __AP_IP__ template substitution - Supported mints section in portal page (shows mint URL, tap to copy) - Fixed mint URL to testnut.cashu.space (was stale in SPIFFS) - DoT reject server on port 853 for DNS-over-TLS fallback - DNS hijack: NXDOMAIN for all non-A queries, no forwarding for unauthed - Playwright tests updated for 200 response on detection URIs - Phase 2 test suite: 20/21 pass (test 22 expiry ping route issue) - Tests 25-27 deferred to Phase 3 (Board B as second client)
2026-05-15Phase 2 WIP: Cashu payment endpoints, session tracking, updated checklistYour Name
- Add cashu.c/h: Cashu token decode (cashuA/base64url), proof state check via mint API, allotment calculator - Add session.c/h: time-based session management with allotment/expiry, spent secret tracking - Add tollgate_api.c/h: HTTP server on :2121 with GET / (kind=10021 discovery), POST / (payment processing), /usage, /whoami - Update captive portal HTML: replace Grant Free Access with Cashu token paste form + Pay & Connect button - Update tollgate_main.c: wire in session manager, TollGate API, 1s session tick loop - Add tests/phase2.mjs: Phase 2 test suite (discovery, invalid token, wrong mint, valid payment) - Update CHECKLIST.md: reflect Phase 1 complete, Phase 2 in progress with known bugs Known issues (not yet flashed): - Stack overflow crash in httpd POST handler (need stack_size=16384 + heap allocations) - cashu_decode_token uses 2KB stack buffer (needs heap alloc) - Mint URL should be testnut.cashu.space (nofee.testnut has API compat issues)
2026-05-15Phase 1 working: captive portal, DNS hijack, NAT-based access controlYour Name
- Fix WiFi init order: netif creation before esp_wifi_init, set mode before set_config - Replace broken netif input filter with NAPT on/off per authentication state - NAPT disabled by default, enabled when client granted, disabled on revoke - Fix test helpers: use -I wlp59s0 for ping, handle nslookup exit code 1 - All 20 API tests pass, all 6 smoke tests pass
