eth_getBalance

PolygonC1

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.

Endpoint

POST https://api.1st-node.com/v1/polygon/rpc

Parameters

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

Returns

QUANTITY — the current balance in wei, hex-encoded.
