Tempo API method that returns the Merkle proof for an account and optionally some storage keys. This is useful for verifying account state without trusting the node.

​
Parameters

  • address — the address to get the proof for
  • storageKeys — array of storage positions to prove (hex strings)
  • blockParameter — the block number (hex) or tag (latest, earliest, pending)

​
Response

  • result — the proof object:
    • address — the account address
    • accountProof — array of RLP-encoded Merkle Patricia trie nodes from state root to account
    • balance — the account balance
    • codeHash — the hash of the account code
    • nonce — the account nonce
    • storageHash — the hash of the storage trie root
    • storageProof — array of storage proofs, one per requested key:
      • key — the storage key
      • value — the storage value
      • proof — array of RLP-encoded trie nodes from storage root to value

const getProof = async () => {

    const proof = await provider.send("eth_getProof", [
      PATHUSD,
      ["0x0", "0x1"],
      "latest"
