Alchemy Debug Bundle
Overview
Collect diagnostic data for Alchemy support tickets: connectivity tests, SDK version, network status, CU usage, and recent error logs.
Prerequisites
- A scoped development or sandbox key supplied through a secret store; never pass the key as a command-line argument or include it in a captured bundle.
- A reproducible issue with the expected network, method, time window, and sanitized request/correlation ID.
- A review path that checks the bundle for credentials, wallet-address privacy concerns, or proprietary application data before it leaves the organization.
Instructions
Step 1: Debug Bundle Generator
// src/debug/alchemy-debug.ts
import { Alchemy, Network } from 'alchemy-sdk';
interface DebugBundle {
timestamp: string;
sdkVersion: string;
environment: Record<string, string>;
connectivity: Record<string, any>;
networkStatus: Record<string, any>;
}
async function generateDebugBundle(): Promise<DebugBundle> {
const alchemy = new Alchemy({
apiKey: process.env.ALCHEMY_API_KEY,
network: Network.ETH_MAINNET,
});
const bundle: DebugBundle = {
timestamp: new Date().toISOString(),
sdkVersion: require('alchemy-sdk/package.json').version,
environment: {
nodeVersion: process.version,
platform: process.platform,
apiKeySet: process.env.ALCHEMY_API_KEY ? 'yes (redacted)' : 'NO — missing',
network: process.env.ALCHEMY_NETWORK || 'ETH_MAINNET',
},
connectivity: {},
networkStatus: {},
};
// Test core connectivity
try {
const start = Date.now();
const blockNumber = await alchemy.core.getBlockNumber();
bundle.connectivity.core = {
status: 'ok',
latencyMs: Date.now() - start,
latestBlock: blockNumber,
};
} catch (err: any) {
bundle.connectivity.core = { status: 'failed', error: err.message };
}
// Test Enhanced API
try {
const start = Date.now();
await alchemy.core.getTokenBalances('0x0000000000000000000000000000000000000000');
bundle.connectivity.enhancedApi = { status: 'ok', latencyMs: Date.now() - start };
} catch (err: any) {
bundle.connectivity.enhancedApi = { status: 'failed', error: err.message };
}
// Test NFT API
try {
const start = Date.now();
await alchemy.nft.getContractMetadata('0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D');
bundle.connectivity.nftApi = { status: 'ok', latencyMs: Date.now() - start };
} catch (err: any) {
bundle.connectivity.nftApi = { status: 'failed', error: err.message };
}
// Multi-network status
for (const [name, network] of Object.entries({
ethereum: Network.ETH_MAINNET,
polygon: Network.MATIC_MAINNET,
arbitrum: Network.ARB_MAINNET,
})) {
try {
const client = new Alchemy({ apiKey: process.env.ALCHEMY_API_KEY, network });
const block = await client.core.getBlockNumber();
bundle.networkStatus[name] = { status: 'ok', block };
} catch (err: any) {
bundle.networkStatus[name] = { status: 'failed', error: err.message };
}
}
const filename = `alchemy-debug-${Date.now()}.json`;
require('fs').writeFileSync(filename, JSON.stringify(bundle, null, 2));
console.log(`Debug bundle saved: ${filename}`);
return bundle;
}
generateDebugBundle().catch(console.error);
Step 2: Bash Quick Diagnostic
#!/bin/bash
echo "=== Alchemy Quick Diagnostics ==="
echo "API Key: ${ALCHEMY_API_KEY:+SET (redacted)}"
echo -n "ETH Mainnet: "
curl -s "https://eth-mainnet.g.alchemy.com/v2/${ALCHEMY_API_KEY}" \
-X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":0}' \
| jq -r '.result // .error.message'
echo -n "Polygon: "
curl -s "https://polygon-mainnet.g.alchemy.com/v2/${ALCHEMY_API_KEY}" \
-X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":0}' \
| jq -r '.result // .error.message'
echo "=== Done ==="
Output
- JSON debug bundle with connectivity, latency, and network status
- SDK version and environment configuration
- Multi-network health check results
Examples
When a testnet application reports intermittent RPC failures, run the generator with a scoped development key and inspect the JSON locally. Confirm it reports SDK version, network status, aggregate latency, and only redacted key state; remove wallet addresses or application payloads if any were added by local instrumentation. Attach the sanitized bundle and relevant request ID to a support ticket. If a bundle exposes a credential or sensitive application data, do not upload it—revoke the exposed credential if necessary, correct the redaction logic, and regenerate the evidence.
Error Handling
| Failure | Response |
|---|---|
| Diagnostic call is unauthorized | Stop the run and verify the scoped key without printing it. |
| A network check times out | Record the network and timeout only, then compare against the provider status page. |
| Bundle contains sensitive data | Quarantine it, rotate any exposed credential, improve redaction, and regenerate. |
| Support needs more context | Provide sanitized request IDs, timestamps, and SDK version—not application secrets or private keys. |
