@dgb-wallet/rpc

JSON-RPC client for DigiByte Core, calling only the read-only + broadcast methods a wallet needs. Companion to ops/setup.sh, which provisions the matching pruned VPS backend.

API

  • new RpcClient({ url, username, password, timeoutMs })
  • getBlockchainInfo(client) — chain tip, sync progress, prune status
  • scanTxOutSet(client, descriptors) — walk UTXO set for descriptors/xpubs; returns matching UTXOs
  • sendRawTransaction(client, hex) — broadcast; returns txid or throws
  • estimateSmartFee(client, confTarget) — DGB/kB fee estimate
  • descriptorForAccount(purpose, xpub, change, rangeEnd) — build BIP44/49/84/86 descriptors with checksums
  • descriptorChecksum(desc), withChecksum(desc) — BIP380 checksum helpers

Demo — real recovery scan via your VPS

Provision the backend once with ../../ops/setup.sh (turnkey for a fresh Ubuntu/Debian VPS). Then:

cd "D:\Dev\SilentCode\Digibyte"
npm install                        # first time only
npm run build -w @dgb-wallet/core

export DGB_RPC_URL=https://your-domain.example.com/
export DGB_RPC_USER=dgb_...
export DGB_RPC_PASSWORD=...
npm run demo -w @dgb-wallet/rpc
# or with a specific seed:
npm run demo -w @dgb-wallet/rpc -- "word1 word2 ... word12"

Scans 3 accounts × 4 descriptor paths × 2 change/receive × 101 addresses each = 2,424 addresses in one RPC call, typically 5–15 seconds on a synced pruned node. Prints every UTXO found with its descriptor path, ready to feed into @dgb-wallet/psbt for spending.

Descriptor checksums

DGB Core requires descriptors passed to scantxoutset to carry a BIP380 checksum. withChecksum(desc) and descriptorForAccount(...) compute it locally so we don't need a round-trip to getdescriptorinfo.

Notes

  • Uses fetch — Node 18+, React Native, and browser extensions all work.
  • Future: swap fetch for @dgb-wallet/net's NetProvider so requests can go through Tor by default (per RESEARCH.md §10.7b).
  • Wallet-side is stateless; the VPS holds the chain state. Client keys never leave the wallet.
