@chainvue/v402-verus-rpc

Minimal, v402-scoped Verus daemon JSON-RPC client: exactly the RPC methods the v402 payment stack needs (verifymessage with checklatest, signmessage, getidentity, block/tx lookups, getcurrencybalance, sendcurrency), wrapped in a 500 ms-timeout + circuit-breaker policy (cockatiel). Includes MockVerusRpc for tests.

This is deliberately not a general-purpose Verus client and will stay minimal — it exists so the payment path has a small, auditable RPC surface.

npm install @chainvue/v402-verus-rpc

import { VerusRpcClient } from "@chainvue/v402-verus-rpc";

const rpc = new VerusRpcClient({
  rpcUrl: "http://127.0.0.1:18843",
  rpcUser: "...",
  rpcPass: "...",
});
const ok = await rpc.verifyMessage("v402test@", signature, message, true);

Failure semantics worth knowing: JSON-RPC application errors (e.g. a malformed signature) do not count as circuit-breaker failures — only transport-level failures trip the breaker, so signature spam cannot deny service.
