5 Winning Projects from the Avalanche Foundation

The Avalanche Foundation proposes five challenges. One is to create an optimally optimized precompiled EVM to solve problems such as the inability to use Solidity contracts and the high cost. The second is to build an optimal subnet UI compatible with Ledger, making it possible to add validators, send transactions, deploy assets/contracts, etc. The third is to create a tool for subnet operators to have a management subnet validator and get a notification service when a specific subnet validator is about to expire. The fourth is to run the most creative and innovative virtual machines in the subnet, and find the best custom VM. The fifth is to create an excellent Dapp on the subnet.

The five winning projects are OracleEVM, SubnetX, subnet.center, AEVEREST, zkID, and each project has received a prize of 20,000 US dollars.

OracleEVM

OracleEVM is a custom EVM that uses stateful precompilation to create high-fidelity financial Efficient access to information, the main advantage is the conservation of block space, efficient access to financial data through pre-compilation, and the validity of financial data is enforced by vm block verification and consensus.

SubnetX

SubnetX is a ledger-compatible subnet creation and management tool with a simple dashboard where users can create subnets and set expiry validators notify.

Subnet.center

Subnet.center is a real-time monitoring/notification system that can notify validators and delegators in different scenarios, such as notification: validator pledge expires, delegation stake expiry, uptime warning (when below 80%), validator stake capacity available (WIP, template/email code ready, trigger required) and new delegators (WIP, template/email code ready ready, requires a completion trigger).

AEVEREST

AEVEREST is a custom VM subclass based on C++ language on Avalanche network.

zkID

zkID is a zero-knowledge proof project, which is used to build a merkle tree using Poseidon hash on the AVAX public chain state, which can be used without the user disclosing his specific address It can be proved in the case of certain circumstances, such as the number of a certain Token owned, a certain type of NFT owned, and participation in the ICO of a certain project, etc.

The 3 winning projects of the Axelar prize pool

The 6 winning projects of the Covalent prize pool

The first challenge from Covalent is to build your own projects using Covalent API endpoints, such as building NFT marketplaces, galleries, on-chain analytics, wallets, asset tracking, ROI, cost basis and tax calculators wait. Among them, MatchMe.NFT and Babalaunch each received a $1,000 prize.

MatchMe.NFT

MatchMe.NFT is a new matching social platform created by the HER DAO team. People can chat in the community of different NFT projects, but it is difficult to Find people with many similar interests in different communities to meet and chat. MatchMe.NFT uses data-driven algorithms such as user NFT collections and interests, and connects their wallets to match people with each other, chat, discuss and share. The project will distribute Tokens in the form of Gamify, and later will provide advanced features that can be accessed using MatchMe Tokens for payment, incentivizing communication between users.

Babalaunch

Babalaunch is a launchpad Dapp on a local subnet.

The second challenge was to build a project using the Covalent API with one of the other Avalanche Summit Hackathon sponsors. Ruby and the WowSwap Probabilistic Liquidation Bot received $2,000 each.

Ruby

Ruby is an NFT marketplace aggregator tool built by @jeansymolanza with @RichardAwoyemi that allows users to buy NFTs in bulk across multiple collections and marketplaces, it also won Joint bounty of Axelar and Covalent.

WowSwap Probabilistic Liquidation Bot

WowSwap Probabilistic Liquidation Bot is a liquidation bot built by the team to improve old bots while remaining lightweight for many users to run.

ExpiryDator and Skia Safe Wallet

ExpiryDator and the aforementioned Skia Safe Wallet each received $500. What ExpiryDator does is that subnet maintainers can be notified when a validator's uptime is reduced to a certain level or when a validator's end time is about to expire.

1 winning item of the Ankr prize pool

Ankr's challenge to the entries was to create a comparison tool that could compare Ankr's Public Avalanche RPC with other projects'. Real-time speed is displayed in the interface, and all endpoints can be optionally added or modified for transparency, presenting accurate results.

ANKR Endpoints

The award went to ANKR Endpoints, a script that pushes metrics to Prometheus and displays the results in Grafana, winning $2500.

3 Winning Projects from Aventures DAO

Aventures DAO is a project that wants to participate in the challenge and can establish a smart contract for DAO investment and fund management. Specifically, fund collection is processed based on pre-calculated shares, and then investment tokens are allocated to each DAO member to invest in specific projects based on the multi-signature of DAO funds.

DAO investment and treasury management Smart contracts

DAO investment and treasury management Smart contracts (DAO investment and treasury management smart contracts) won a $5000 prize, allowing authorized users to create investment events, investors can Among them, the custom investment native Token or ERC20 Token is open to everyone, and the investment can also be cancelled.

The second challenge is to develop tools that can provide a decentralized mechanism for some NFT treasuries (such as guilds). Its goal is to build a trade-in NFT system that allows governance to allocate emissions to sell targeted NFTs.

AVentures Token Distribution

AVentures Token Distribution won $3,000 for a smart contract that handles token distribution from DAO to different investors.

YieldPool

Win $2000 for YieldPool, which lets users channel their own NFT funds, combining DeFi and social investing.
