⚡ When to Use
TriggerAction
- Embedded wallet experiences with low-friction onboarding
- Swap-first UX where gas funding hurts conversion
### Integration
Add `gasless=true` to a v1 swap request:
```typescript
const res = await fetch(
"https://api.carbium.io/api/v1/swap" +
"?owner=WALLET&fromMint=USDC_MINT&toMint=SOL_MINT" +
"&amount=1000000&slippage=100&provider=raydium&gasless=true",
{ headers: { "X-API-KEY": process.env.CARBIUM_API_KEY! } }
);
```

💡 Examples

1. Get API Keys

| Product | Signup | Notes | |---|---|---| | RPC + gRPC + WebSocket | rpc.carbium.io/signup | One key covers RPC, WebSocket, and gRPC | | Swap API | api.carbium.io/login | Separate key, free account, instant |

Programmatic key provisioning is not yet available. Keys must be created via the dashboards.

2. Set Environment Variables

export CARBIUM_RPC_KEY="your-rpc-key"
export CARBIUM_API_KEY="your-swap-api-key"

3. Security Rules (Non-Negotiable)

  • Never embed keys in frontend/client-side code
  • Never commit keys to version control
  • Use environment variables: CARBIUM_RPC_KEY, CARBIUM_API_KEY
  • Rotate immediately if exposed
  • Keep keys server-side only

    • 📋 Tips & Best Practices

    Security

  • Keep API keys server-side only — never in frontend bundles or mobile clients
  • Use environment variables (CARBIUM_RPC_KEY, CARBIUM_API_KEY)
  • Rotate keys immediately if exposed
  • Restrict endpoints by domain/IP in the RPC dashboard where practical

    • Rate Limiting

  • HTTP 429 is an architecture signal, not just a retry cue
  • Separate dev/staging/prod keys
  • Isolate retry paths from decision logic
  • Do NOT retry sendTransaction before checking getSignatureStatus

    • Transaction Submission

  • Use skipPreflight: true only after validating the quote — saves ~200ms
  • Use VersionedTransaction (V0) for Address Lookup Table (ALT) support
  • Prefer HTTP polling for confirmations over WebSocket (more reliable)
  • Keep blockhashes fresh — they expire after ~60 seconds

    • Commitment Levels

  • Default to confirmed for most operations
  • Use processed only for price feeds or low-stakes reads
  • Use finalized for irreversible confirmations and high-value operations
