# proposed custom errors
# source: https://eth.wiki/json-rpc/json-rpc-error-codes-improvement-proposal
#1 Unauthorized Should be used when some action is not authorized, e.g. sending from a locked account.
#2 Action not allowed Should be used when some action is not allowed, e.g. preventing an action, while another depending action is processing on, like sending again when a confirmation popup is shown to the user (?).
#3 Execution error Will contain a subset of custom errors in the data field. See below.
#100 X doesnt exist Should be used when something which should be there is not found. (Doesnt apply to eth_getTransactionBy_ and eth_getBlock_. They return a success with value null)
#101 Requires ether Should be used for actions which require somethin else, e.g. gas or a value.
#102 Gas too low Should be used when a to low value of gas was given.
#103 Gas limit exceeded Should be used when a limit is exceeded, e.g. for the gas limit in a block.
#104 Rejected Should be used when an action was rejected, e.g. because of its content (too long contract code, containing wrong characters ?, should differ from -32602 - Invalid params).
#105 Ether too low Should be used when a to low value of Ether was given.
#106 Timeout Should be used when an action timedout.
#107 Conflict Should be used when an action conflicts with another (ongoing?) action.
