Plugins are contracts linked to the xGRAIL contract. Some are native and directly made by the Camelot team (dividends, yield booster, launchpads and more to come...) but others can be freely integrated by anyone from the ecosystem.
Users will be able to take advantage of plugins' unique benefits by allocating xGRAIL to them, by directly staking into the xGRAIL contract.
There is a default 0.5% deallocation fee on all xGRAIL plugins.
In other words, if you allocate 100 xGRAIL to a plugin and later deallocate the whole amount, you will only get back 99.5 xGRAIL.
