eth_getProof

POST

Returns the value stored in the Storage of the specified address in a format that includes a Merkle proof. The returned proof can be used to verify that the queried storage state has not been tampered with.

param[0]

addressstringrequired

Address is expressed as a 20-byte hexadecimal string, the address format used in EVM-compatible blockchains.

param[1]

storageHashesarrayrequired

Array of storage hashes for querying values in the Storage of a specific address. Each hash is a 64-character hex string.

param[2]

blockNumberOrHashOrTagstringrequired

Use one of block hash, block number, or block tag to specify a block.

Block number: hex string (ex. "0x1")
Block hash: 64-character hex string (ex. "0x39008d07edf93c03bb9d1cfc80598fcf63f441ec86e9de3733fa6a484980ca48")]
Block tag: enum string (ex. "latest", "earliest", "pending")
- earliest: The oldest available block on the chain.
- finalized: A recently finalized block that can no longer be changed. Primarily used in proof-of-stake (PoS) blockchains.
- safe: A recent block considered safe by the network (immune to reorgs).
- latest: The most recent block on the chain (may be subject to reorgs).
- pending: The next block to be mined, including pending transactions in the mempool.
