FluidContractFactory ​
A contract that allows deployers to deploy any contract by passing the contract data in bytes
The main objective of this contract is to avoid storing contract addresses in our protocols which requires 160 bits of storage Instead, we can just store the nonce & deployment of this address to calculate the address realtime using "AddressCalcs" library
FluidContractFactory__InvalidOperation ​
error FluidContractFactory__InvalidOperation()Thrown when an invalid operation is attempted
LogContractDeployed ​
event LogContractDeployed(address addr, uint256 nonce)Emitted when a new contract is deployed
Parameters ​
| Name | Type | Description |
|---|---|---|
| addr | address | The address of the deployed contract |
| nonce | uint256 | The nonce used for deployment |
LogUpdateDeployer ​
event LogUpdateDeployer(address deployer, uint16 count)Emitted when a deployer's count is updated
Parameters ​
| Name | Type | Description |
|---|---|---|
| deployer | address | The address of the deployer |
