Pichiu Network decision checklist
Before integrating with Pichiu Network, evaluate these key decisions:
| Criterion | What to check | Why it matters |
|---|---|---|
| Endpoint reliability | Does the provider offer load-balanced RPCs? | Unreliable endpoints cause failed oracle updates and increased latency. |
| WebSocket support | Are WSS URLs available for real-time data? | Many oracle use cases require continuous subscription to price feeds or event logs. |
| Archive node access | Does the provider support archive queries? | Historical oracle data may be needed for audit or verification. |
| Rate limits | What is the request per second (RPS) limit? | High-frequency oracle calls can hit limits if not accounted for. |
| Dedicated node option | Can you reserve a dedicated node for exclusive use? | Production apps often need guaranteed throughput without contention. |
What is Pichiu Network?
Pichiu is a decentralized oracle network built on Kusama. It provides smart contracts with access to real-world data such as asset prices, randomness, weather, and sports outcomes. Pichiu uses a bond-based validator system to ensure data accuracy and availability. For developers building on Kusama parachains or Substrate-based chains, Pichiu offers a secure and trust-minimized way to fetch off-chain information.
Key Features of Pichiu Network
- Decentralized data sourcing: Multiple validators aggregate and verify data before submission.
- Substrate native: Optimized for Polkadot and Kusama ecosystems.
- Flexible feed types: Supports price feeds, VRF (Verifiable Random Function), and custom data feeds.
- Transparent governance: Validators stake tokens to ensure honest reporting.
How to Connect to Pichiu RPC
To interact with Pichiu, you need a JSON-RPC endpoint. The Pichiu oracle network exposes an RPC interface similar to Ethereum's JSON-RPC. Below are typical connection parameters.
Chain Settings
| Parameter | Value |
|---|---|
| Network ID | 211 (or check latest) |
| RPC Endpoint (HTTP) |
https://pichiu-rpc.onfinality.io (example) |
| RPC Endpoint (WSS) |
wss://pichiu-rpc-ws.onfinality.io (example) |
| Native Token | PCHU |
| Explorer | https://pichiu.subscan.io |
Note: Replace with actual endpoints from your provider. OnFinality supports Pichiu Network endpoints as part of its RPC service.
Example: Fetch Latest Data from a Pichiu Oracle Feed
Use a standard JSON-RPC call to read an oracle feed contract. Below is a curl example:
curl -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0xOracleFeedAddress","data":"0xfeaf968c"}, "latest"],"id":1}' \
https://pichiu-rpc.onfinality.io
Replace 0xOracleFeedAddress with the feed contract address and 0xfeaf968c with the function selector (e.g., latestRoundData()).
WebSocket Subscription for Real-Time Updates
For continuous monitoring, use WebSocket subscriptions:
const WebSocket = require('ws');
const ws = new WebSocket('wss://pichiu-rpc-ws.onfinality.io');
ws.on('open', function open() {
ws.send(JSON.stringify({
jsonrpc: '2.0',
id: 1,
method: 'eth_subscribe',
params: ['logs', { address: '0xOracleFeedAddress' }]
}));
});
ws.on('message', function incoming(data) {
console.log(JSON.parse(data));
});
Common Pitfalls and Troubleshooting
1. Incorrect Network ID
Always verify the current network ID. Pichini may update during runtime upgrades. Use eth_chainId to confirm.
2. Rate Limiting
If you receive 429 Too Many Requests, consider upgrading to a dedicated node or using a provider with higher limits.
3. WebSocket Disconnections
Ensure your client handles reconnections gracefully. Many providers close idle WebSocket connections after a timeout.
4. Missing Archive State
If you need historical oracle data, ensure your endpoint supports archive queries. Check the provider's archive node availability.
When to Use a Managed RPC Provider for Pichiu
Running your own Pichiu node requires infrastructure management, synchronization time, and ongoing maintenance. For most teams, a managed provider like OnFinality offers:
- Pre-configured endpoints with load balancing.
- Global node distribution for low latency.
- Production-grade reliability with monitoring.
- Both public and private endpoint options.

Key Takeaways
- Pichiu Network is a decentralized oracle platform on Kusama, providing reliable off-chain data to smart contracts.
- Connecting via RPC requires correct chain settings and endpoint selection.
- WebSocket subscriptions are recommended for real-time data feeds.
- Evaluate provider features like archive nodes, rate limits, and dedicated node options for production use.
- A managed RPC service can simplify operations and improve reliability.
Frequently Asked Questions
