Zora Archive Node RPC

Query the full history of Zora — balances, contract storage, and transaction traces at any past block — with archive node access included on every paid SwiftNodes plan. No separate archive tier, no per-request fees.

Endpoint

https://rpc.swiftnodes.io/rpc/zora?key=YOUR_API_KEY

Archive queries use the same Zora HTTP endpoint — just pass a historical block tag. The matching WebSocket endpoint is wss://rpc.swiftnodes.io/ws/zora?key=YOUR_API_KEY.

Query historical Zora state

// Read historical state at a past block on Zora (archive query)
const balanceAtBlock = await client.getBalance({
  address: "0x0000000000000000000000000000000000000000",
  blockNumber: 1_000_000n,
});

// Replay a transaction's execution trace (requires archive data)
const trace = await fetch("https://rpc.swiftnodes.io/rpc/zora?key=YOUR_API_KEY", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    jsonrpc: "2.0", id: 1,
    method: "debug_traceTransaction",
    params: ["0x<txhash>", { tracer: "callTracer" }],
  }),
}).then((r) => r.json());

What archive access unlocks

• eth_getBalance / eth_call at any historical block number
• eth_getStorageAt for contract storage at a past block
• debug_traceTransaction to replay and inspect old transactions
• Point-in-time analytics, accounting, and reconciliation

Zora is a Layer 2 (OP Stack optimistic rollup, Optimism Superchain), with ~~2 seconds block times and soft confirmation in seconds; hard finality after the optimistic challenge window settles to ethereum l1 finality. Historical queries reach back across its entire chain history.
