The dRPC Data API is a crypto wallet API that returns wallet balances, DeFi positions, transaction history, and historical PnL across 8,000+ protocols, 35+ EVM chains, and Solana from a single REST endpoint. It removes the indexing layer most teams build themselves, so you query high-level portfolio data directly instead of parsing logs and running your own databases.<\/p>

If you are already on a paid dRPC plan, it is live in your existing API keys today.<\/p>

Why raw RPC is not enough for wallet data<\/h2>

Standard RPC nodes are built to broadcast transactions and read chain state. They are not built to answer “what does this wallet hold right now, across every chain, with USD values and spam filtered out.”<\/p>

To get that, teams usually build a custom indexing stack: subgraphs, databases, log parsers, and price feeds. It takes months, costs real money in server time, and breaks when a node desyncs. A crypto wallet API removes that work by serving the aggregated, decoded result instead of the raw inputs.<\/p>

What you can build with the dRPC Data API<\/h2>

A wallet balance API call returns structured JSON, so you ship features instead of maintaining infrastructure:<\/p>

  • Unified wallets and portfolios.<\/strong> Real-time balances and prices across 35+ EVM chains and Solana in one call. Spam tokens are filtered out by default.<\/li>
  • DeFi portfolio tracking.<\/strong> Position-level data for 8,000+ protocols, covering supply, borrow, LP tokens, staking, and rewards.<\/li>
  • Transaction history.<\/strong> Decoded, human-readable transfers and contract interactions instead of raw hex.<\/li>
  • Tax and accounting.<\/strong> Historical PnL, cost-basis data, and reward breakdowns.<\/li><\/ul>

    How this crypto wallet API is different<\/h2>

    There are other indexed data APIs. Two gaps separate most of them from production needs: how fast coverage expands, and how fresh the data is.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

    Coverage that keeps up with DeFi<\/h3>

    Web3 moves faster than most API roadmaps. If you need a protocol that is not yet covered, you submit a request and it is live in 48 hours. A new EVM chain takes 5 days. Your integration code does not change; the backend scales behind it.<\/p>

    Real-time data, not a stale cache<\/h3>

    Many providers refresh DeFi positions on a timer. A user can close an Aave position and still see it as active in your app hours later. The dRPC Data API uses a transaction-triggered cache that updates the moment an on-chain transaction settles, so users see current positions rather than an old snapshot.<\/p>

    An SLA that is backed financially<\/h3>

    Production workloads run under a 99.9% uptime SLA. If dRPC misses it, you are compensated.<\/p>

    Make your first request<\/h2>

    There is no separate onboarding. If you are on a paid dRPC plan, the Data API is already active on your keys.<\/p>

    1. Log into your dashboard, open an active API key, and copy the base URL from the Data API card. It follows the pattern https:\/\/lb.drpc.live\/lambda\/<YOUR_API_TOKEN><\/code>.<\/li>
    2. Pull balances for a wallet. Example using vitalik.eth on Ethereum:<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
