ADX: new staking contract and migrator contract #206
Description
Summary
decided that we're going to use ADX-STAKING as a basis but add variable lock staking and stk* mechanics (1 stk token = 1 base token)
Full to do list:
- stk mechanics (transfer, transferFrom, balanceOf, totalSupply, EVENTS)
- permit2 (x402)
- remove penalize/claim
- variable lock staking; when you're setting your own unlock time, you can only decrease it if it's your first stake (previous
shares[msg.sender] == 0) - ensure there's no division by zero and extra gas overhead from stk* additions
- make tokens non-transferrable during unbonding commitment
- expose principal - decided not to do it
- internal audit
- implement
emit ShareValueUpdated() - full tests - test: do migration, set penalty max (or do any call to old staking pool) & penalize old pool, set new governnace
- approvals
- automated deployment, devnet
Full to do, migrator:
- basic migrator contract
- value erosion or deadline - decided on deadline for now - we can use pool penalizing/claiming to erode value later
