Deflationary feeBurn | TokenV2 | Ongoing BUIDl


The feeBurn has been in action since the first SPARTAv2 token transfer. It starts at 0% and grows/shrinks with the token’s total supply. The feeBurn is set to be 1% *if* the token’s total supply is at the max (300M) however the max supply is programmatically impossible to reach. Read more about this new deflationary aspect below:

In just over a week of SPARTAv2 (token) upgrade DApp going live, we have already seen over 700 users and 32 Million SPARTA upgraded to SPARTAv2. (This was also during a period where seasoned crypto participants have probably taken a smart move in steering clear of socials/blockchain and enjoying some fresh air) Screenshot 23 MAY 21:

To acquire SPARTAv2 (token), please read the below medium article for more details on how to:

  • Upgrade existing v1 tokens to v2 (Mainnet & Testnet)
  • Claim your share of SPARTA allocated to users impacted by the LP drain (Mainnet & Testnet)
  • Interact with DAppV2 to help test the V2 contracts (Testnet)

Phase 1 — SPARTA V2 (Token) — Completed!

Affected Users Snapshot

Massive thanks to PeckShield for helping provide resources to one of our community contributors who worked on getting this snapshot! They were also very swift to reach out after the LP-drain and provide their advice and support to help understand and move forward.

Huge thanks also to Chiachih Wu for personally reaching out to some of the contributors and providing generous advice and support with the exploit and also the snapshot process.

All contributors who had interactions with PeckShield & Chiachih Wu throughout this process have reported very incredible generosity with their time and impressive knowledge. Can pretty confidently state that we wouldn’t have this snapshot right now without your help!

  • Put the contracts through a code review process on CodeArena
  • At the same time; continue adding automated tests and review the code within the community
  • Update contracts based on results from CodeArena and other reviews


Community Forum

  • Setup categories & get the community contributing good questions about DAO proposals & mechanics of AMMs so that they can be padded out into longer-form go-to guides to post in the channels

Phase 3 — Deploy & Iterate

  • Enable Bond allocations to get TVL into the V2 pools
  • Deploy Lending to testnet
  • Continue ahead with the previous plans!

  • Added zoom class



  • Changed language names to be shown in the native language (ie. Greek -> Ελληνικά)
  • Changed DropdownItem to Button
  • Restyled and refactored


  • checkArrays() — enable actions to run on mainnet. Add in getSpartaGlobalDetails() && getBondSpartaRemaining() && getReserveGlobalDetails() to the loop


  • Change <I> classed icons to <img>
  • Add in tooltips to show what each icon represents (for users who don't recognise the icons)



  • Added hardcoded ‘Burn’ & ‘Bond’ figures for distro from V1
  • getTotalSupply() — Handle properly; it now uses: SPARTAv1 totalSupply plus SPARTAv2 totalSupply
  • getCirculatingSupply() — Handle properly; it now uses: getTotalSupply() minus SPARTA in reserve & bond contracts (released but non-circulating SPARTA)
  • getMarketCap() — This now multiplies the circulating supply * SPARTA token price
  • Enabled this component to show up on mainnet too now that it’s handled correctly
  • Visually show the v1 vs v2 circulating tokens
  • Visually show the distribution of totalSupply based on whether they were allocated via Burn, Bond or Emissions
  • Make the mapped out contracts more compact with 2 Cols


  • Enable wallet balances/assets on mainnet now that the actions are not bypassed




  • getCuratedPools() — Check for valid poolFactory; if not the contract will not be called and the array will be empty
  • getTokenDetails() — Refactor; cleanup. We no longer use UTILS to get all this info; we simply call a max of 2 contract calls per asset. We now use static token icons for SpartaV1, SpartaV2 & BNB


  • getTokenContract() — removed
  • getWbnbContract() — removed


  • Changed getSpartaContract() to getSpartaV2Contract() for specific SPARTAv2 interfacing







  • That left no requirement for the getData() loop; so it was removed
