ots_hasCode

Checks whether an address contains contract code at the specified block. This is a lightweight alternative to calling eth_getCode and checking if the result is empty.

Checks whether an address contains contract code at the specified block. This is a lightweight alternative to calling eth_getCode and checking if the result is empty.

Parameters

#	Type	Description
1	`string`	Address to check.
2	`string`	Block tag (`"latest"`, `"earliest"`) or hex block number.

Returns

Type	Description
`boolean`	`true` if the address has deployed contract code, `false` for externally-owned accounts (EOAs).

Example

curl -s -X POST https://rpc.pulsechain.box \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "ots_hasCode",
    "params": [
      "0x2b591e99afE9f32eAA6214f7B7629768c40Eeb39",
      "latest"
    ],
    "id": 1
  }'

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": true
}

Notes

Returns false for addresses that have never been used or are standard EOA wallets.
Since this is an archive node, you can query any historical block number to check whether an address had code at that point in time.
More efficient than eth_getCode when you only need a boolean answer.
