‌Protocol Contracts V3

GitHub Repo: https://github.com/spartan-protocol/spartan-contracts

minor changes + ext testing

  • added sanity checks on pool creation to ensure input of both assets > 100000 wei (a fixed number is problematic, but even with an expensive asset like BTC this still allows for a pool creation as low as $0.000000006 USD TVL)
  • this in theory would leave a min remainder of 10wei tokens if the user adds and then instantly removes 100% of their liquidity (when combined with the 10000wei fixed LP units on creation and 1wei locked/burned permanently)
  • added tests for each of these new sanity checks
  • added a test to check the emitted PoolCreated event args are correct

continued testing + adjustments

  • small refactor (gas saving) in Pool contract
  • refactored use of ONE in Tools contract with 1 ether instead
  • changed calcLiquidityUnits() fallback for initial add to match recent changes (static 10,000 units)
  • fixed the slip adjustment check to be within 2% instead of 100% exact
  • converted the Tools math to normal math operators
  • fixed the wrong/broken math in Tools (too many LP units were given to subsequent liquidity providers)
  • bumped up the initial liqAdd of the stablecoin pool to 100k ether-units each so that we can test underflow 1-wei rounding
  • changed the btc:native initial liqAdd ratios to resemble actual BTC & BNB asset values
  • changed all use of ethers to hre-ethers for the extended hardhat functionality
  • changed iBEP20 interfaces to ERC20
  • added a changeHandler call to the fixture so that the Tools contract can be correctly picked up when its called externally (when adding liquidity for instance)
  • added exported references to each token contract as addr2 (alternatively we can just grab the contract objects attached to addr1 and call .connect(addr2) but we can decide on that later)
  • removed the args from the createPoolsFixture as that is not supported (as an actual fixture)
  • created export refs to each pool contract attached to addr1 && addr2
  • moved onto the pool contract for adding test units
  • added a test to make sure addForMember() reverts if either input is !>0
  • added a test to make sure addForMember() reverts if the calculated LP units to mint is < 1 wei

test file structure cleanup

  • renamed some test files
  • moved some test files / file structure
