A-Chain Alpine (testnet)
Public RPC not answering (checked 2026-09-24)
Alpine's public RPC below returns 404 and its Hyperion reports an RPC error. Use the XPR 1:1 demo network to try PulseVM in the meantime. This page will be updated when Alpine is back.
Alpine upgrades frequently as development ships. Most recent genesis: 2026-08-20 (v0.7.x era). If a cached value stops working, re-check here or see Updates.

Testnet
Alpine is the public test network for A-Chain. Core/staking token is SYS (4 decimals); an XPR token is issued on pulse.token as well.
Antelope-style
/v1/chainREST is not exposed on Alpine today; a nodeos-style/v1/chainAPI inside the node is merged and ships in the next release. Use the native JSON-RPC above (pulsevm.getInfo,pulsevm.getTableRows, …) or the Hyperion/v2API for history. See /build/api for the method table. (The XPR 1:1 demo network below does serve/v1REST.)
XPR 1:1 demo network (community-operated)
A live demonstration network running a byte-exact import of XPR Network testnet state on current PulseVM — real accounts, contracts, balances, and permissions at production scale, continuing the source chain's block numbering. Full story: The 1:1 Demo Network.
| RPC (native JSON-RPC) | https://xpr-rpc-testnet.pulsevm.dev (pulsevm.* methods) |
REST (/v1/chain) | https://xpr-rpc-testnet.pulsevm.dev/v1/chain/… — Antelope-compatible, via gateway on the same host |
| History (Hyperion v2) | https://xpr-hyperion-testnet.pulsevm.dev |
| Explorer | testnet.explorer.pulsevm.dev |
| Chain ID | 71ee83bcf52142d61019d95f9cc5427ba6a0d7ff8accd9e2088ae2abeaf3d3dd (same as XPR testnet — the state is the point) |
| Core token | XPR (4 decimals) |
Demo, not a service
Community-operated, single validator, and may be re-imported from newer snapshots as tooling evolves. Great for exercising real Antelope state on PulseVM — not a place to keep anything you care about. See caveats.
