Deflationary feeBurn | TokenV2 | Ongoing BUIDl

Summary

With the SPARTAv2 (Token) now deployed to mainnet; a contributor took the time to discuss some of the intricacies and opportunities involved with the new ‘feeBurn’ in the transfer function.

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)

Spartan Protocol GitBook

Some new & old community members have put their hands up recently to help get the Spartan Protocol GitBook to reflect current progress and iterations of the protocol — head over and check it out to learn more.

This will be an ongoing focus for the wider community to contribute towards.

Contributor’s Focus

The contributor focus moving forward has been broken into rough phases. This has been done to highlight that the original goal has not changed. This also acknowledges and embraces the fact that there is some rebuilding required in order to get there.

Phase 1 — SPARTA V2 (Token) — Completed!

Affected Users Snapshot

A snapshot of the state of all user’s liquidity holdings (Wallet Holdings, DaoVault Staked & Bond Locked) was taken from a block height of just before the V1 LP drain. This was cross-referenced with the depth of the pools to work out the SPARTA units that were taken from liquidity providers. See the result below:

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!

Phase 2 — Spartan Protocol V2 (Protocol)

SPARTA V2 (Token) — CEXs

Work with the CEXs to ensure the SPARTA holders all have their tokens upgraded as easily as possible. One would expect the exchanges to handle this for them.

Binance CEX: Pending completion
BKEX: Pending completion
MXC: Pending completion

SPARTA V2 (Token) — DEXs

Work with DEXs & aggregators to ensure the new SPARTA token address is added to their lists. All AMMs that already have SPARTAv1 in their selection lists have been reached out to and the ball is rolling on getting SPARTAv2 added or SPARTAv1 replaced with SPARTAv2.

SpartanContracts

Continue updating V2 contracts to suit the changes to the base contract and get it finalised ready for the CodeArena bounty
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

DAppV2

Update the DAppV2 to suit any changed contracts

Community Forum

A community forum for longer-form & categorised discussion has been created in GitHub: join the discussion here.

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

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