Setting Up API Keys

Why Ethonode uses keys

Ethonode pulls live prices from CoinGecko, EVM wallet data from Moralis, and Solana wallet data from Helius. All three have generous free tiers.

We run a hybrid model. Every user starts with a shared Ethonode key that works for light usage. Upgrading to your own free key from each provider unlocks higher rate limits and faster sync — the quota is yours, not ours.

CoinGecko

Used for: live asset prices, market caps, charts, news, search.

Adding keys in Ethonode

Keys are encrypted at rest with AES-256-GCM and only decrypted when we call the provider on your behalf. You can replace or remove a key at any time.

• Open Settings → API Keys from the user menu.
• Click Add your key on the provider card.
• Paste the key, optionally name it, and click Verify & Save.
