eth_getStorageAt on Ethereum
Reads a raw 32-byte storage slot from a contract at a given block. Used to inspect state that isn't exposed by a public getter.
Slot layout is compiler- and version-specific, and proxies keep their logic's state elsewhere — compute mapping/array slots carefully. Prefer eth_call whenever a public getter exists.

Accounts & state on Ethereum
Ethereum state is the largest of any EVM chain. Reads default to the latest block; pass an explicit block tag for point-in-time reads, and expect deep-historical state queries to be slower than near-head ones.

eth_getStorageAt on Ethereum — FAQ
How do I call eth_getStorageAt on Ethereum?
POST a JSON-RPC 2.0 request with "method": "eth_getStorageAt" to NodeFlare's Ethereum endpoint at https://rpc.nodeflare.app/eth/public. No API key is required for the public endpoint.
What does eth_getStorageAt cost on the free tier?
eth_getStorageAt is weighted at 2 compute units per call. The free tier includes 2,000,000 CU/month, so that is roughly 1,000,000 eth_getStorageAt calls per month — no credit card.
Is eth_getStorageAt available on the public Ethereum endpoint?
Yes. eth_getStorageAt works on the public Ethereum endpoint (https://rpc.nodeflare.app/eth/public) with no API key, rate-limited per IP. A free key adds higher limits and a dedicated path.
Anything Ethereum-specific to know when using eth_getStorageAt?
Ethereum state is the largest of any EVM chain. Reads default to the latest block; pass an explicit block tag for point-in-time reads, and expect deep-historical state queries to be slower than near-head ones.
