Submission Details
Severity:
checkpoint() does not create checkpoints
protocol attempts to implement a time-weighted weight which should change the weight of a guage in respect to time.
function checkpoint() external updateReward(msg.sender) {
emit Checkpoint(msg.sender, block.timestamp);
}
but when checkpoint is called it only emits an event, no action is performed.
Proof of Concept
it("should update weights through checkpointing", async () => {
await baseGauge.checkpoint();
const period = await baseGauge.weightPeriod();
- expect(period.startTime).to.be.gt(0);
+ expect(period.startTime).to.be.equal(0);
});
Impact
weights would not be updated through checkpointing.
Recommendation
calculate the time-weighted weights and update weight through checkpoint
