About the Delay Modifier
This modifier allows avatars to enforce a time delay between when a module initiates a transaction and when it can be executed by an avatar.
This means an approved address can execute transactions only after a cooldown period and, optionally, before an expiration time.
The interface mirrors the relevant parts of the Gnosis Safe's interface, so this contract can be placed between Gnosis Safe modules and a Gnosis Safe to enforce a time delay between transaction creation and execution.
Transactions are executed in order. The owner of the owner can skip transactions by advancing the transaction nonce.
Features
- Enqueue transactions
- Enable and disable modules
- Public function to execute the next transaction in queue
- Skip transactions by advancing the nonce
- Set cooldown and expiration periods
Flow
- Enqueue transactions by calling
execTransactionFromModule() - Wait for cooldown ⏱️
- Anyone can execute the next transaction by calling
executeNextTx
Solidity Compiler
The contracts have been developed with Solidity 0.8.0 in mind. This version of Solidity made all arithmetic checked by default, therefore eliminating the need for explicit overflow or underflow (or other arithmetic) checks.
