eth_getStorageAt

Returns the value stored at a specific storage position of a contract. This allows direct inspection of a contract's internal state without calling a view function.

Parameters

Returns

string -- The value at the given storage position as a 32-byte hexadecimal string.

Example

curl -s -X POST https://rpc.pulsechain.box \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_getStorageAt",
    "params": ["0xA1077a294dDE1B09bB078844df40758a5D0f9a27", "0x0", "latest"],
    "id": 1
  }'

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x577261707065642050756c73650000000000000000000000000000000000001a"
}

Notes

• Storage slots are 32-byte key-value pairs. Slot 0x0 is the first storage slot of the contract.
• The storage layout depends on the Solidity compiler version and variable declaration order. Consult the contract's source code or storage layout documentation to determine which slot holds which variable.
• For mappings and dynamic arrays, the actual storage slot is computed using keccak256. For example, to find mapping[key] at slot p, the storage position is keccak256(key . p) where . is concatenation.
• As a full archive node, historical storage values at any block number are available, making this useful for forensic analysis of contract state changes.
• The example queries slot 0 of the WPLS contract at 0xA1077a294dDE1B09bB078844df40758a5D0f9a27.
