Events
Flow relies on a set of core contracts that define key portions of the Flow protocol. Those contracts are core contracts and are made to emit the events documented below. You can read about the core contracts here and view their source code and event definitions.
Events emitted from core contracts follow a standard format:
_10A.{contract address}.{contract name}.{event name}
The components of the format are:
contract address- the address of the account the contract has been deployed tocontract name- the name of the contract in the source codeevent name- the name of the event as declared in the source code
Flow Token Contract​
Description of events emitted from the FLOW Token contract.
The contract defines the fungible FLOW token. Please note that events for the fungible token contracts are the same
if deployed to a different account but the contract address is
changed to the address of the account the contract has been deployed to.
Tokens Initialized​
