feat(hive): Hive blockchain integration — firmware through txbuilder#187
Merged
Conversation
Points modules/keepkey-firmware to the feature/hive branch which adds Hive blockchain signing support (HiveGetPublicKey, HiveSignTx). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Points to BitHighlander/device-protocol@f2b32d8 which adds messages-hive.proto with HiveGetPublicKey/HiveSignTx/HiveSignedTx (wire IDs 1600-1603).
…build pipeline
- chains.ts: add HIVE to chainFamily union, CONFIGS entry (BIP44 m/44'/1275'/0'/0/0,
color #E31337, hiveGetPublicKey/hiveSignTx), and CAIP/networkId/decimal fallbacks
(hive:beeab0de/slip44:1275, decimals 3) since pioneer-caip PR not yet published
- index.ts: fix address extraction to check result?.publicKey for Hive (hiveGetPublicKey
returns { publicKey: 'STM...' } not { address: '...' })
- Makefile: add DEVICE_PROTOCOL_BUILD_STAMP — auto-builds device-protocol on make dev/install
- modules/device-protocol: bump to feature/hive (adds messages-hive.proto to build:js,
drops broken build:json which pbjs v0.0.5 cannot parse with reserved fields)
POST /addresses/hive: derives STM-prefixed public key via hiveGetPublicKey,
caches result, returns { address: 'STM6...' }. Requires firmware v7.14.0+.
- txbuilder/hive.ts: buildHiveTransfer (fetches tx-params + resolves STM key → account name via Pioneer in parallel) and broadcastHiveTx (POSTs signed tx to Pioneer /api/v1/hive/broadcast with reassembled JSON body) - txbuilder/index.ts: wire case 'hive' into buildTx / signTx / broadcastTx; add pioneerBaseUrl param so custom Pioneer URLs flow through to txbuilder - index.ts: fix fromAddress extraction for hiveGetPublicKey (returns publicKey not address); pass getPioneerApiBase() to buildTx - rest-api.ts + swagger.json: GET /api/pioneer/status and POST /api/pioneer/url endpoints for switching Pioneer backend at runtime

Summary
Full Hive blockchain integration from firmware proto through transaction builder. All API verification checkpoints pass with device connected on feature/hive firmware.
