Data Sources

• Prices: CoinGecko free API (no key, rate limited to 30/min)
• EVM balances: Public RPCs or Etherscan free tier
• Solana balances: solana CLI or public RPC
• Token lists: CoinGecko token list

Limitations

• CoinGecko free tier: 30 calls/min, no historical data beyond 1 year
• Public RPCs may rate limit under heavy use
• ERC-20 token detection requires known token list (top 500 by market cap)
• For full token scanning, consider adding Moralis or Alchemy API keys
