eth_getBalance

AvalancheC1

Returns the balance of an account in wei at the requested block. Pass a historic block number to read a past balance — this resolves against our archive nodes, so old heights work, not just the latest state.

Parameters

Name	Type	Description
address	DATA, 20 bytes	Address to query the balance for.
block	QUANTITY \| TAG	Block number, or "latest"/"earliest"/"pending".
