Documentation for eth_defi.balances.fetch_erc20_balances_fallback function.
- fetch_erc20_balances_fallback(web3, address, tokens, block_identifier, decimalise=True, chunk_size=50, token_cache=LRUCache({}, maxsize=1024, currsize=0), gas_limit=10000000, raise_on_error=True, disable_multicall=None)
Get all onchain balances of the token.
Safe variant
Try multicall approach first
If it fails for some reason, fall to individual JSON-RPC API approach
A reason for the failure would be crappy RPC providers
See
fetch_erc20_balances_multicall()for usage and argument descriptions.- Parameters
disable_multicall (bool) –
Disable multicall behaviour.
If set to None autodetect local dev/test chain and disable based on the presence of Anvil: assume no multicall contract deployed there. On the mainnet fork, assume the presence of multicall contract.
