system_name - Asset Hub RPC Method
Get the node implementation name on Asset Hub. Identify the client software powering your node for diagnostics, compatibility checks, and infrastructure management.
Returns the node implementation name on Asset Hub. This identifies the client software running the node (e.g., "Parity Polkadot", "Substrate Node", "Astar Collator").
Why Asset Hub? Build on Polkadot's system parachain managing $4.5B+ in DOT tokens, native USDC/USDT, and NFTs with 50-90% lower fees than Relay Chain, fee payment in any supported asset, 1.5M+ accounts migrated, and trustless Ethereum bridge access.
When to Use This Method
system_name is essential for asset issuers, stablecoin integrators, and teams requiring low-cost token management on Polkadot:
- Client Identification -- Determine which Substrate client implementation your node is running (useful when multiple implementations exist)
- Infrastructure Monitoring -- Track client types across your validator or collator fleet on Asset Hub
- Bug Reports and Diagnostics -- Include client implementation details when reporting issues for native stablecoin transfers (USDC, USDT), DOT staking and governance, and cross-chain asset management via XCM
- Compatibility Checks -- Verify that the node implementation supports features required by your application
Code Examples
Common Use Cases
1. Full Node Identity Report
Gather complete node identity details in a single call:
import { ApiPromise, WsProvider } from '@polkadot/api';
async function getNodeIdentity(endpoint) {
const provider = new WsProvider(endpoint);
const api = await ApiPromise.create({ provider });
const [name, version, chain] = await Promise.all([
api.rpc.system.name(),
api.rpc.system.version(),
api.rpc.system.chain()
]);
const identity = {
implementation: name.toString(),
version: version.toString(),
chain: chain.toString(),
endpoint
};
await api.disconnect();
return identity;
}
// Example output:
// { implementation: "Parity Polkadot", version: "0.9.43-ba6af17", chain: "Polkadot", endpoint: "..." }2. Infrastructure Audit Across Nodes
Audit client implementations across a fleet of Asset Hub nodes:
async function auditFleetClients(endpoints) {
const results = await Promise.all(
endpoints.map(async (endpoint) => {
try {
const provider = new WsProvider(endpoint);
const api = await ApiPromise.create({ provider });
const name = await api.rpc.system.name();
const version = await api.rpc.system.version();
await api.disconnect();
return { endpoint, client: name.toString(), version: version.toString(), status: 'ok' };
} catch (error) {
return { endpoint, client: null, version: null, status: 'unreachable' };
}
})
);
// Group by client implementation
const byClient = {};
for (const node of results) {
if (node.client) {
byClient[node.client] = byClient[node.client] || [];
byClient[node.client].push(node);
}
}
console.log('Client distribution:', Object.keys(byClient).map(
(k) => `${k}: ${byClient[k].length} nodes`
));
return results;
}3. Connection Health Check with Client Info
Include client implementation in health-check responses:
async function healthCheckWithClientInfo(api) {
try {
const name = await api.rpc.system.name();
const version = await api.rpc.system.version();
const chain = await api.rpc.system.chain();
return {
healthy: true,
client: `${name.toString()} v${version.toString()}`,
chain: chain.toString(),
checkedAt: new Date().toISOString()
};
} catch (error) {
return {
healthy: false,
error: error.message,
checkedAt: new Date().toISOString()
};
}
}Error Handling
Common errors and solutions:
| Error Code | Description | Solution |
|---|---|---|
| -32603 | Internal error | Node may be starting up -- retry after delay |
| -32005 | Rate limit exceeded | Reduce request frequency or implement client-side rate limiting |
| Connection refused | Node unreachable | Verify the RPC endpoint URL and that the node is running |
