DevUpdate: ~$40k BNB received from BSC BUIDL Program | DappV2 | SpartanContractsV2


This week Spartan Protocol received over $40k in BNB (at the time) in BNB-gas reimbursements as part of the BSC BUIDl Program. We are calling all Spartans to comment in the Twitter post + Telegram with ideas on how to use these funds to grow the protocol. Great ideas have included funding community grants and building out new feature sets.

All ideas are welcome as long as they look to the long term growth and development of the Spartan protocol ecosystem. The funds are public and auditable in the . Please; if you have a cool idea that you can build or coordinate with others to build; share it with the community and the Spartan community bounty wallet will fund you/it!

Having learnt how to use GitHub to see the commits flow in has been eye-opening for just how hard this group of contributors are working! Aroo!!

Contributors continue to BUIDL the DAppV2 rollout with the contract ‘wen merge’ happening yesterday. I am surprised no one has asked what this means!

What does this post- ‘wen-merge’ era mean? Well, essentially it means that the V2 contracts are in no-major-change mode whilst it goes through its last stages of the internal and external-contributor audit.

We urge with a little more push now for the community to go to GitHub and have a look at the code if you have been dragging your feet!

SpartanDev — SpartanContractsV2

  • Force harvest if weight > 0 instead of pool’s weight > 0
  • Fixed harvest() calc
  • Changed Pool & Synth naming convention in constructor to -SPP (pool) & -SPS (synth)
  • Changed synth mappings to shorter and more human-readable (_collateralBalance to lpBalance) & (_synthDebtFromLP to lpDebt)
  • Added two helper functions for those mappings (for DApp)
  • Updated automated tests accordingly
  • Added two helper functions for Router revenue (dividends) mappings
  • Refactor Migration contract
  • Improve gas by reducing some args
  • Major gas-reduction in addLiquidity (asym) by simply adding the tokens one-sided instead of swapping them first. Saving more than half of the previously-used gas before the refactor
  • This means no swap txn & no dividend; however, it instead creates an arb-opportunity which will theoretically create the same end resulting-swap without the LPer having to foot the bill for the extra gas
  • Makes more sense for the user benefitting from the transaction to pay the gas especially as that logic is already included in the swap function (removes a double-up)
  • Let Arbers do the arbs! Let LPers do the LPs!
  • Added automated test to ensure a flag is raised in the future if proposed code prevents users from withdrawing from the DAO if the pool is no longer curated
  • Update to Solidity 0.8.3
  • Replace safeMath operations with inbuilt math symbol operators (new Solidity) refactor based on that
  • Refactor lending contract
  • And of course; the all-important ‘wen merge’ happened on Apr 18th!
