Restoring from a snapshot

  1. 1.Verify the download against the SHA-256 in latest.json: sha256sum latest-snapshot.bin.zst
  2. 2.Decompress: zstd -d latest-snapshot.bin.zst
  3. 3.Start nodeos with a fresh data dir: nodeos --snapshot latest-snapshot.bin --data-dir /path/to/fresh/data ...

Filenames are stable — only the contents update on each refresh. Safe to script: curl -O the same URL each run.

XPR Network Docs

Core protocol documentation — accounts, contracts, wallets, and the developer tooling maintained by the network.

Open docs

PulseVM Docs

Everything on the PulseVM execution layer — accounts, permissions, finality, resource model, and running your own network.

Open docs

Pulse Cutover

Programmatic Antelope → PulseVM cutover agent — BP / API / Hyperion modes, snapshot ceremony with byte-exact verification, rehearsed 22/22 against live XPR testnet state.

Open docs

Open Source

Most of what we ship is open source — fork the code, run your own node, contribute a fix, or use the repos as a starting point for your own XPR Network project.
