Returns the balance of the account of a given address.

Parameters

  • DATA, 20 Bytes - Address to check for balance.

Converting eth_getBalance response into ETH

To convert the hex string response, measured in Wei to a decimal value measured in ETH. We need to complete two steps:

  1. Convert the hex response into decimal (Wei)
  2. Convert the Wei decimal into ETH decimal (10^18 wei = 1 eth)

Depending on what library or language you are using, there are several options here.

# conversion from hex string to decimal
dec = int("hex strong response",16)

# conversion from Wei to to ETH
ethBalance = dec*(10**18)Parameters
DATA, 20 Bytes - address to check for balance.
QUANTITY|TAG - integer block number, or the string "latest", "earliest" or "pending", see the
default block parameter
.
