Block

The Default Block Parameter

When requests are made that act on the state of Klaytn, the last default block parameter determines the height of the block.

The following options are possible for the defaultBlock parameter:

• HEX String - an integer block number

• String "earliest" for the earliest/genesis block

• String "latest" - for the latest mined block

• String "pending" - for the pending state/transactions

klay_blockNumber

Returns the number of most recent block.

Parameters

None

Return Value

Type	Description
QUANTITY	Integer of the current block number the client is on.

Example

// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"klay_blockNumber","params":[],"id":83}' https://kaia.nownodes.io

// Result
{
  "jsonrpc": "2.0",
  "id":83,
  "result": "0xc94"
}

klay_getHeaderByNumber

NOTE: This API is supported from Klaytn v1.7.0.

Returns information about a header by number. This API works only on RPC call, not on JavaScript console.

Parameters

Type	Description
QUANTITY | TAG	Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in the default block parameter.

Return Value

See klay_getHeaderByHash

klay_getStorageAt

Returns the value from a storage position at a given address.

Parameters

Type	Description
20-byte DATA	Address of the storage.
QUANTITY	Integer of the position in the storage.
QUANTITY | TAG | HASH	Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in the default block parameter, or block hash.

:::note

NOTE: In versions earlier than Klaytn v1.7.0, only integer block number, the string "earliest" and "latest" are available.

:::

Return Value

Type	Description
DATA	The value at this storage position.

Example

Calculating the correct position depends on the storage to retrieve. Consider the following contract deployed at 0x295a70b2de5e3953354a6a8344e616ed314d7251 by address 0x391694e7e0b0cce554cb130d723a9d27458f9298.

contract Storage {
    uint pos0;
    mapping(address => uint) pos1;

    function Storage() {
        pos0 = 1234;
        pos1[msg.sender] = 5678;
    }
}

Retrieving the value of pos0 is straight forward:

curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0", "method": "klay_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' https://kaia.nownodes.io

{"jsonrpc":"2.0","id":1,"result":"0x00000000000000000000000000000000000000000000000000000000000004d2"}

Retrieving an element of the map is harder. The position of an element in the map is calculated with:

keccak(LeftPad32(key, 0), LeftPad32(map position, 0))

This means to retrieve the storage on pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:

keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))

The Klaytn console which comes with the klay library can be used to make the calculation.

"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"

Now to fetch the storage:

curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0", "method": "klay_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' https://kaia.nownodes.io

klay_syncing

Returns an object with data about the sync status or false.

Parameters

None

Return Value

Object|Boolean, an object with sync status data or false when not syncing:

Name	Type	Description
startingBlock	QUANTITY	The block at which the import started (will only be reset, after the sync reached his head).
currentBlock	QUANTITY	The current block, same as klay_blockNumber.
highestBlock	QUANTITY	The estimated highest block.
pulledStates	QUANTITY	The number of state entries processed until now. If the sync mode is not "fast", zero is returned.
knownStates	QUANTITY	The number of known state entries that still need to be pulled. If the sync mode is not "fast", zero is returned.
