BUIDL-Weekly: 25JUL22–31JUL22

New CEX Listing on Bitrue

The week started off racing with a new CEX listing for SPARTA : USDT on Bitrue Exchange. A big thanks to Bitrue for taking the reigns on this listing and supporting our community project!

CZ <> Spartan Art

Shout out to Alex Melas from the Spartan community who made this amazing art piece depicting CZ_binance as a Spartan holding strong in the shield wall. Check out more of his amazing work via his ArtStation profile


CZ really showed his Spartan spirit this week with a callout to the 300 movie calling it “One of my favourites” and of course, the Spartan community loved it! Obviously, Spartan Protocol is not a meme coin project, but the narrative and theme have important alignments to the project & community’s foundations.

New CEX Listing on BitKan

Yes, you are seeing double 👀! The end of the week presented us with yet another CEX listing for the SPARTA token, this time on BitKan. There is a trading competition in place thanks to BitKan too, so make sure you check out the details and win yourself a share of the $30K prize pool along with a beautiful drum and some SPARTA merch.

Community DApp

GitHub Repo:


Conscious integration of BraveWallet

Completed a conscious integration of BraveWallet

BraveWallet connection flow:
- Detect .isBraveWallet and give the button state accordingly
- User clicks BraveWallet button if available
- Wallet asks permission, awaits user action
- User confirms, the DApp reloads with wallet selected (held in localStorage for auto-connect next time)
- User is able to view assets and add them to the wallet with icons etc

BraveWallet change network flow:
- User (already connected BraveWallet) changes network selection
- If the network is not already in BraveWallet, the user is prompted to add the network with info pre-filled
- The user is then prompted to change the network
- DApp reloads with wallet and network pre-loaded

fix #839 consistent types

Made the returned value types consistently BigNumber for:

  • `calcSynthAPY`
  • `calcDaoAPY`
  • `calcAPY`

fix#841 synth positions

  • added conditionals for invalid `getSynth()` results
  • checked other `get`s throughout, there are a couple of instances where this could apply but technically the sanity checks prior and/or selection style makes it not possible (currently) will re-actively update if the feature-set changes enough to change this

fixes #840 handle rounding of negative numbers

  • Changed logic of `formatFromUnits()` && `formatFromWei()` to treat negative numbers the same as positive numbers when rounding for the front-end
  • Changed the less than/greater than/equal to checks to the more accurate BigNumber versions (this only matters for the `<= 0` conditional where that JS limit can be reached, but made sense to do so with all conditionals seeing as we are working with a BigNumber)

To do:

Protocol Site

GitHub Repo:



  • Added support for animation start on scroll for older devices
  • Added hover animation for buttons

  • Added font loading check only for the dapp button
  • Added animations to the token section
  • added ‘small’ contributors: the ability to add a ‘small’ contributor to the team members for more fine-tune-able contributor sorting logic

To do:

Protocol Contracts V1 — V2

GitHub Repo:

Ecosystem Project: SpartanSwap

SpartanSwap is just a placeholder for now, but it is a separate project with the intention of building an alternative frontend for users to interact with the Spartan Protocol pools. With a focus on swap functionality to start with and longer-term plans to iterate towards becoming a swap aggregator for BNBChain and potentially multi-chain after that

Ecosystem Project: SpartanArena

SpartanArena is another separate project with a focus on creating subprojects that lean more towards ‘gaming’. Some ideas in the works for the future may include an NFT looter game, lottery and a prediction/parimutuel game

GitHub Repo:

Ecosystem Project: SpartanToolkit

Spartan Toolkit is an ecosystem project spawned from the Spartan Protocol community aiming to improve tooling for projects and users within the BNBChain ecosystem including Beacon, Smart & BAS chains.

Web3BNB Library

GitHub Repo:

A React library with the intention of providing builders with a plug-and-play solution for any web3 wallet compatible with BNB ecosystem chains (Beacon, Smart, BAS etc)

  • Added WalletConnect provider along with basic connection and state logic
  • Removed the setupClient callback bandaid fix for the BNC bug (handled at the multi send end-function level now so we don't have to reset the client each txn)
  • Added loop to get all BeaconChain wallet’s token balances every 15s and add to redux store
  • Changed BinanceWallet signing delegate to use a raw singing method instead of the internal transaction-type signing methods as they seem to have buggy behaviour with different issues on each network and between different txn types — raw sign means less info parsed for the user in the wallet but at least we know the msg they are signing has not been mutated or blocked due to a failed API call
  • Added a WalletConenct signing delegate using .sendCustomRequest and the bnb_sign method
  • Added XDefiWallet signing delegate placeholder for future integration

BNB Beacon Chain Toolkit DApp

GitHub Repo:

A tooling user interface for users + projects on BNB Beacon Chain. Batch-send, freeze/unfreeze, deploy BEP2 token etc without touching the command line!

  • Added a staging deploy workflow
  • Cleaned up webpack & deps
  • Updated Bootstrap to 5.2.0
  • Added ‘wrong address selected’ handling & alert to Wallet component
  • Added ‘Connect with WalletConnect’ option to Wallet component
  • Normal transfer & multi send/batch transfer functional MVP complete — users can connect their wallet -> select an asset from their available balances -> manually add recipient/s & amount/s or import from CSV -> send msg to their wallet for signing then broadcast/complete the txn
  • Added simple mobile menu

BNB Smart Chain Toolkit DApp

GitHub Repo:

Tooling and informational user interface for users + projects on BNB Smart Chain
