- 50:50 split upon the very first chicken-in to initialize the bTKN/TKN pool.
- Market price = redemption price = 1
- Forbid chicken-ins during 1 week (tbd)
- Forbid redemptions during 1 month (tbd)
- BondNFT
- sLUSDToken
- mock Curve pool
- mock Yearn LUSD and Curve vaults
- createBond
- chickenIn
- chickenOut
- redeem
- Change accrual function to asymptotic curve, remove cap constraint
- refund functionality inside chickenIn
- Shifting functions
- Replace refund functionality with permanent bucket
- Liquity-like redemption fee
- Extract common functionality in core contracts
- Extract common setup functionality in unit tests
- Basic math function for converting to/from 18 digit fractions
- Implement main events
- Settle on best Solidity version to use (OZ contracts are v8+, and Slither detects v8+)
- Add return values to all state-changing functions for integrations
- Tax on chicken in + incentive for bTKN/TKN pool
- Adapt shifting function: revert when Curve price crosses boundary
- Determine most accurate way to compute
totalAccruedLUSDfrom Yearn and Curve - Determine Curve trade quantity calculation for shifting functions (we simply revert if the price crosses the $1.0 boundary)
- Implement Yearn Registry check for latest vaults and migration functionality
- Connect to real Yearn and Curve contracts
- Mainnet hard fork testing
- Create thorough unit test plan: negative tests, multiple bonds per user, etc.
- Create list of system properties/invariants and add
asserts - More extensive testing for edge cases (e.g. pending harvests, harvest losses, external calls to Yearn/Curve reverting, etc)
- Run Slither / MythX
- Systemic fuzzing (Dani?)
- Determine redemption fee formula
- Determine sLUSD accrual function / controller
- Decide on NFT enumeration (i.e. getting all of a user's bonds), and/or extra trade functionality
