Dev Update

SpartanDev: 23/08/21 – 29/08/21

Happy first birthday to Spartan Protocol! Automated testing and DApp development continues towards aligning with the new contracts

SpartanDev: 23/08/21 – 29/08/21

Summary

Happy Birthday Spartans !!!

Thankyou for lending your support and determination to the shield-wall, it goes along way for a community driven project. Safe to say its been a pretty wild ride so far, we hope you have your seatbelts fastened because things are about to speed up.

Automated testing is in full swing, putting the protocol through the grinder and helping streamline processes. Whilst this has been happening the remaining contributors have been refining the DApp ready to take full use of V2 contracts. Onwards.

Contributor’s Focus

CodeArena Contest

  • COMPLETED ✅ — triage and prioritise the feedback submitted from the CodeArena wardens during the contest to prepare for the judges
  • IN PROGRESS — work through the post-contest tasks with the C4 judges & team for the eventual allocation of awards to security wardens
  • IN PROGRESS — communicate with security wardens to clarify/expand on feedback

Once these tasks above are completed, the CodeArena report will be published, and Spartans will be able to review the final list of findings to understand how the changes that have already been implemented into Spartan Protocol (in the PostC5 repository) fit into this greater picture.

As discussed previously, we continue to build and refine code in parallel with the CodeArena post-contest actions.

SPARTA V2 (Token)

  • COMPLETED (& ONGOING) — Work with DEXs & aggregators to ensure up-to-date information on the new SPARTA token (retiring the previous contract address) (1inch, PancakeSwap etc.)
  • COMPLETED (& ONGOING) — Work with token-tracking informational websites to ensure new token info is up-to-date (BSCscan, CoinGecko, CoinMarketCap etc.)

SpartanContracts

  • COMPLETED ✅ — Sort and prioritise all CodeArena submissions into contract scopes along with tags based on ‘actionable’ or ‘discussion points’
  • COMPLETED ✅ (only minor changes as required from now on) — Implementing refinements to contracts to address C4 & contributor feedback since the C4 contest code-freeze
  • IN PROGRESS — Rebuild automated testing
  • Deploy updated V2 contracts to BSC testnet for at least 1 week of community stress testing
  • Deploy completed V2 contracts to BSC mainnet

DAppV2

  • COMPLETED (& ONGOING) — Set up a reliable index of history scoped to contracts (use this for positions page etc)
  • IN PROGRESS — Update the DApp to suit the contract changes
  • IN PROGRESS — Use the new testnet subgraph to build a more lightweight positions page for V2

After Mainnet

  • Enable Bond allocations to replenish TVL into the V2 pools
  • March onwards with our original goals of building the decentralised, yield-generating synthetics protocol on Binance Smart Chain

contracts/BondVault.sol

  1. Updated comments

contracts/Dao.sol

  1. Updated comments
  2. Changed nested mappings to private and created getters/helpers instead
  3. Removed transfer require() from moveBASEBalance()

contracts/DaoVault.sol

  1. Updated comments
  2. Removed old mappings
  3. Added purgeDeployer()
  4. Fixed getMemberPoolDepositTime() helper (was pointing to wrong mapping)

contracts/Pool.sol

  1. Updated comments
  2. Added PoolFactory to onlyPROTOCOL() modifier
  3. Added Router to onlyDAO() modifier
  4. Changed baseCap to WEI in constructor
  5. Changes to safetyCheck()
  • Changed to run every time even if the pool’s freeze status is already true
  • Now we check the rate every time but *only* update the oldRate if an hour has passed and the pool’s status is not frozen
  • Added extra logic for if the pool is frozen to automatically handle the freeze status
  • If the pool is frozen but the ratio is back at safe levels; flick frozen status to false (for the pool; not global)
  • If the pool is frozen and 1 hour has passed; have the ratio of the pool come towards the new rate at a 25% weighted rate. ie. (currentRate + (oldRate * 3) ) / 4

contracts/Reserve.sol

  1. Added a freezeTime variable to potentially handle auto-unfreeze

contracts/Router.sol

  1. Updated comments
  2. Removed feeAllocation variable and assignment (no longer used; was apart of older more complex dividend logic)
  3. Added purgeDeployer()
  4. addLiquidityAsymForMember() — changed back to use the pool’s swap function instead of interfacing with the Router’s swap function (this also removes the dividend component)
  5. zapLiquidity() — removed dividend logic (save gas)
  6. swapSynthToAsset() — moved the swapPool requires inside the else {} statement to avoid wasted logic/gas
  7. _addDividend() — bypass dividend if emissions are off
  8. currentPoolRevenue() — removed helper (use mapping instead)
  9. pastPoolRevenue() — removed helper (use mapping instead)
  10. Removed unneeded require() for transfers between contracts:
  • removeLiquidityExactAsym()
  • zapLiquidity()
  • swapAssetToSynth()
  • _handleTransferIn()

8. Added require() for globalFreeze to be false after the safetyCheck

  • swapAssetToSynth()
  • swapSynthToAsset()

contracts/poolFactory.sol

  1. Updated comments
  2. Added require() to prevent a SPARTAv2:SPARTAv2 pool
  3. _handleTransferIn() — removed unneeded require() for transfers between contracts

contracts/synthVault.sol

  1. Changed non-nested mappings to public and removed helper

Community Contribution

Spartan Protocol is at its core, a community-driven and led project. In this vein, the more contributors the better. There is a great opportunity for community members to contribute by making LP reward analysis tools, etc.

Recently, community members have been graciously funnelling in to contribute to explainer articles, ideas and even $SPARTA donations to support the growth of the platform.
