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; PulseVM v1.0.0 serves a nodeos-style/v1/chainAPI inside the node, but Alpine has not been upgraded to it. Use the native JSON-RPC above (pulsevm.getInfo,pulsevm.getTableRows, …) or the Hyperion/v2API for history. See /build/api for the method table.
