v2.4.0-rc1
Pre-release
The modifications between the version v2.3.0 and this version are not audited !!!
This intermediate release adds mainly functions to retrieve information from the snapshotModule or the ERC20BaseModule in batch for gas optimization. It is useful for:
-Dividend payment based on the user's balance (snapshot)
-Transfer restriction bases on the user's balance (vesting rule or partial lock)
snapshotModule
- Create an interface
ICMTATSnapshotwith the main public functions for the SnapshotModule to make easier the calls to a contract including a snapshotModule, useful e.g. for debt payment. - Replace
getSnapshotInfoBatchbySnapshotInfo. This function gets a user's balance specified in parameter and the total supply. - Add a new function
SnapshotInfoBatchto get several user's balances and the total supply.
ERC20BaseModule
Add a function balanceInfo to get the balance for a list of addresses and the total supply
Useful to perform transfer restriction based on the user's balance (e.g vesting rule or partial lock).
ValidationModule
Create an internal function _validateTransferByModule which performs check with others module (PauseModule & EnforcementModule)
