From affceea03e2032dc86674c20d6673470200d9af0 Mon Sep 17 00:00:00 2001 From: Vladimir Rogojin Date: Sat, 6 Dec 2025 12:48:37 +0100 Subject: [PATCH 01/51] feat: implement multi-node IPFS upload and Nostr pin broadcasting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add getAllBackendGatewayUrls() and getBackendPeerId() helpers to ipfs.config - Configure ipfs1 peer ID for WSS connection - Implement direct API upload to backend nodes via /api/v0/add - Add backend connection maintenance with auto-reconnect - Create NostrPinPublisher service for broadcasting pin requests - Integrate NostrPinPublisher into WalletGate on authentication - Add peer connection/disconnection logging for debugging The browser Helia node now: 1. Uploads content directly to all configured backend nodes 2. Publishes pin request events to Nostr for network-wide pinning 3. Maintains persistent WSS connection to backend for bitswap 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/components/auth/WalletGate.tsx | 19 +- .../wallet/L3/services/IpfsStorageService.ts | 249 +++++++++++++++++- .../wallet/L3/services/NostrPinPublisher.ts | 160 +++++++++++ src/config/ipfs.config.ts | 40 ++- src/config/nostrPin.config.ts | 21 ++ 5 files changed, 482 insertions(+), 7 deletions(-) create mode 100644 src/components/wallet/L3/services/NostrPinPublisher.ts create mode 100644 src/config/nostrPin.config.ts diff --git a/src/components/auth/WalletGate.tsx b/src/components/auth/WalletGate.tsx index 1f640a0f6..ab5e0d5bf 100644 --- a/src/components/auth/WalletGate.tsx +++ b/src/components/auth/WalletGate.tsx @@ -1,8 +1,10 @@ -import type { ReactNode } from "react";

charset=UTF-8 Content-Transfer-Encoding: 8bit - Add Unicity-based verification before accepting tombstones from remote - Archive tokens on every addToken() call for recovery purposes - Use SDK's isTokenStateSpent() for proper spent status verification - Load trust base from local ServiceProvider instead of HTTP fetch - Handle missing tokens (absent from remote without tombstone) - Restore unspent tokens from archive if tombstone is invalid - Add null-safe handling for spent token logging - Add integrity verification after sync operations This prevents token loss when remote devices have stale tombstones or skip versions during IPNS sync. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../L3/services/ConflictResolutionService.ts | 170 ++++- .../wallet/L3/services/IpfsStorageService.ts | 516 ++++++++++++++- .../wallet/L3/services/NostrService.ts | 61 +- .../L3/services/TokenValidationService.ts | 271 +++++++- .../wallet/L3/services/TxfSerializer.ts | 121 +++- .../wallet/L3/services/types/TxfTypes.ts | 85 ++- src/repositories/WalletRepository.ts | 595 +++++++++++++++++- 7 files changed, 1708 insertions(+), 111 deletions(-) diff --git a/src/components/wallet/L3/services/ConflictResolutionService.ts b/src/components/wallet/L3/services/ConflictResolutionService.ts index 01960c63b..6f49ebe5a 100644 --- a/src/components/wallet/L3/services/ConflictResolutionService.ts +++ b/src/components/wallet/L3/services/ConflictResolutionService.ts @@ -10,12 +10,20 @@ import type { TokenConflict, MergeResult, TxfTransaction, + TombstoneEntry, } from "./types/TxfTypes";

However, nametags are published using the L3 identity key from UnifiedKeyManager. The L1 wallet may have addresses from different BIP32 paths (e.g., m/84'/1'/0'/0/0) while the L3 identity always uses m/44'/0'/0'/0/{index}. Different paths = different private keys = different IPNS names. This fix ensures IPNS lookup uses l3Identity.privateKey (from UnifiedKeyManager) instead of addr.privateKey (from L1 wallet scan), so cross-browser nametag discovery works correctly. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- src/components/wallet/L3/onboarding/CreateWalletFlow.tsx | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/components/wallet/L3/onboarding/CreateWalletFlow.tsx b/src/components/wallet/L3/onboarding/CreateWalletFlow.tsx index 34e814d76..333d0c068 100644 --- a/src/components/wallet/L3/onboarding/CreateWalletFlow.tsx +++ b/src/components/wallet/L3/onboarding/CreateWalletFlow.tsx @@ -283,6 +283,12 @@ export function CreateWalletFlow() { path: addr.path || `m/44'/0'/0'/0/${addr.index}`, hasNametag: !!existingNametag, existingNametag: existingNametag?.name, + // Enable IPNS nametag fetching for addresses without local nametag + // IMPORTANT: Use l3Identity.privateKey (from UnifiedKeyManager) for IPNS derivation, + // NOT addr.privateKey (L1 wallet).
