Why Mintra v0.2?
An NFT app like Mintra is no easy task. There is a constant battle between the demand for shiny new features & the subtle, yet ever growing challenges of scope creep. This leads to constant decision making between "nice to have" things vs. critical features for MVP public releases. There were some features that we deemed to be absolutely critical for Mintra's final testnet release, and ultimately the mainnet release - and now they are here, plus more. Everything is simply better now. Let's explore these new updates!
Performance + UX
Sometimes it's the little things. We've improved a ton of frontend details related to performance & UX - we improved the home page, added a new Explore Users page, upgraded the NFT card design massively, improved user profile pages, optimized the entire site for faster load times, and made overall site navigation much clearer & more detailed for new & experienced users alike. After just a few seconds of using Mintra v0.2, you will feel the difference.
Explore Users
NFTs can be a social experience too. Whether you want to see who is spending the most, making the most, or selling the most NFTs, you can easily sort Mintra users by Top Earners, Top Spenders, & Most Items Sold on the new Explore Users page. This is an easy, intuitive way to explore addresses that are involved or finding success in the Pulsechain NFT space.
Misc. Updates
- New Contract Addresses page for easy access to official Mintra contract addresses, supported tokens, & chain info.
- New Blog page for users to stay up to date on Mintra's latest releases, updates, news, etc.
- Profile Page: Users can now filter their NFT portfolios by switching between Assets, Activity, Listings, Bids, & Offers on their profile pages.
- NFT Card: Full image no longer hidden by info / stats. Removed background blur
- Homepage: Global marketplace stats now take up less space.
- Homepage: NFT's (for sale, on auction, minting now) & collections all reorganized into carousels
Solidity
Sometimes it's the big things. Mintra v0.2 brings some huge Solidity updates that we deemed to be critical for the full coding, testing, & auditing process of this release. From thoughtful integration of ERC-1155 support and ERC-20 support, to an improved buy&burn experience, this release further cement's Mintra's position as the leader of the Pulsechain NFT apps. Let's explore all these updates.
ERC-1155 Support
From .pls domain names, to gaming items, to metaverse land and more, there are many ERC-1155 collections users know and love. As the leading NFT marketplace on Pulsechain, the ability to support both the first & second most popular NFT token standards was a no-brainer. We are happy to announce that ERC-1155 (or "PRC-1155") support is now live on Mintra. This expands the world of NFT's that Mintra can offer for users to trade, and allows NFT creators to more comfortably deploy ERC-1155 collections, knowing that Mintra can easily support them. Go see if you can find your .pls name on the marketplace now!
ERC-20 Support
Up until now, every public Mintra deployment has had one massive constraint - PLS was the only supported currency users could use to trade NFT's. Ever since the ERC-20 token standard was created, communities have gathered & rallied around these tokens. These passionate communities and their tokens have become one of the most prominent phenomena of L1 (particularly EVM) chains. Pulsechain itself is no exception. New and old "PRC-20" tokens alike have the potential to bring massive adoption to the dapps that support & build value for them.
We are proud to announce that Mintra now supports the trading of NFT's (both ERC-721's and ERC-1155's) using PRC-20 tokens! This introduces endless possibilities and reduces friction for users to discover value on their NFT's using virtually any PRC-20 token they desire. And of course - $MINT itself is supported as well! The list of all supported PRC-20 tokens and their contract addresses can be found on the Contract Addresses page.
Fees / Tokenomics
With the introduction of PRC-20 support to trade NFT's on Mintra, the tokenomics for both $MINT staking rewards and buy&burn bounties had to adapt. After careful thought, we came up with a brilliant solution - Mintra's feeSplitter.sol smart contract now splits its token balances into 3 unique categories: $PLS, $MINT, & all other PRC-20 tokens. These different categories determine the paths through which these different tokens flow after they've been collected as fees in the feeSplitter.sol smart contract:
$PLS:
Users pay 2.25% platform fees.
- 1/3 for $MINT Staking Rewards (directly in the form of $PLS)
- 1/3 for $MINT Buy&Burn ($PLS gets swapped for $MINT, then that $MINT gets burned)
- 1/3 for rootAddress
$MINT:
Users pay 1.50% platform fees (33.3% less than everyone else).
- Full amount burned!
All other PRC-20 tokens:
Users pay 2.25% platform fees.
- 1/3 for $MINT Staking Rewards (PRC-20 gets swapped for $PLS, then that $PLS gets sent to $MINT stakers)
- 1/3 for $MINT Buy&Burn (PRC-20 gets swapped for $MINT, then that $MINT gets burned)
- 1/3 for rootAddress
Burn / Flush Page
The decentralized ethos of smart contracts combined with some best practices in Solidity, led to the creation of our new Flush function. By cleverly moving Mintra's BuyAndBurn.sol contract into the feeSplitter.sol contract, we accomplished a few amazing things:
It is 100% up to users to call a public function known as the Flush function. This Flush function allows users to select one or more of the tokens that are sitting inside of the Fee Splitter, and sends them to their appropriate paths based on their categories (as described above). This effectively means that users run the system and are responsible for all token flows, from buy&burn token swaps, to sending stakers their yield, to sending the rootAddress any tokens. This function rewards users 0.1% of any tokens they flush as the incentive to run the function if it becomes profitable to do so.
2nd Security Audit
Mintra's development ethos is one that values security over speed. Before the first public deployment of Mintra on Pulsechain testnet, we made sure to have a smart contract security audit done on the full Solidity codebase. The full audit report can be found on CoinFabrik's website: https://www.coinfabrik.com/blog/mintra-audit/.
After this initial public deployment, we set out to continue building all the new features & support described in the sections above. Staying true to our ethos, we had a second security audit done on all the new Solidity code. The new audit report will soon be (if it's not already by the time of reading) available on CoinFabrik's blog.
Now What?
Mintra v0.2 on Pulsechain testnet is the closest thing you will get to what Mintra on Pulsechain will be. Play around with the site - create new or trade existing NFT's, participate in the MINT token ecosystem, & explore the world of Pulsechain NFT's on Mintra. Stay tuned on social media to be the first to know when Mintra launches on Pulsechain mainnet in Q4 2023.
