On August 11, 2022, Chefs implemented some configuration upgrades to take full advantage of MasterChef v2. It eliminates the 45,000 CAKE daily burn for the legacy lottery injections. Those burns will now be handled by MasterChef v2 directly along with the usual weekly CAKE burn. Therefore, the effective emissions are now even lower.
In addition to the above, a dynamic amount of CAKE is also minted to the Dev address at a rate of 9.09%. This means that if 100 CAKE are harvested, then 9.09 CAKE is minted in addition and sent to the Dev Address.
All CAKE minted to the Dev address is burned in the weekly burn and never enters circulation.
As such, we haven't included it in the above emission rate.
As well as the above, CAKE is also burned in the following ways:
0.0575% of every trade made on PancakeSwap V2
100% of CAKE sent to the Dev address
100% of CAKE performance fees from IFOs
100% of CAKE spent on Profile Creation and NFT minting
100% of CAKE bid during Farm Auctions
20% of CAKE spent on lottery tickets
20% of all profits from Perpetual Trading
45,000 CAKE per day (historically assigned to the lottery)
3% of every BNB Prediction markets round is used to buy CAKE for burning
3% of every CAKE Prediction markets round
2% of every yield harvest from all the flexible staking positions in CAKE pool
2% of every NFT sale on the NFT Market is used to buy CAKE for burning
Why is the CAKE burn manual?
To hit the ground running, PancakeSwap launched as an MVP (minimum viable product) with the MasterChef contract emitting 40 CAKE per block. For that reason, the early team didn't add additional functions such as the ability to customize the CAKE minting logic. The team has been controlling CAKE emissions through a manual burn process by creating two pools in MasterChef v1:
Legacy Lottery Pool (PID - 137) - burned CAKE from the lottery
Burn Pool (PID - 138) - burned CAKE per block
These pools work similarly to the farms, where the Chefs can adjust the percentage of the 40 CAKE per block allocated to it after each CAKE emission reduction vote.
However, in April 2022, PancakeSwap migrated to a new MasterChef v2 contract. The ratio of the CAKE burn per block is finally controlled by a dedicated contract. This allows the burn to be much more accurate.
Due to MasterChef v2 occasionally harvesting the full 40 CAKE per block. The supply shown on the homepage (or some 3rd party trackers) might suddenly jump by several million CAKE.
Don't worry - EMISSION IS NOW CONTROLLED CAREFULLY BY MASTERCHEF V2. CAKE TO BURN WILL NEVER ACTUALLY ENTERS CIRCULATION!
