Quantus is a Layer 1 blockchain designed to keep digital assets secure against the emerging threat of quantum computing. Built on Polkadot's Substrate framework and secured by proof-of-work, it replaces elliptic-curve cryptography with lattice-based, post-quantum signatures (an ML-DSA / CRYSTALS-Dilithium scheme), adds a ZK-friendly Poseidon2 hash and a Plonky2-based proof-aggregation layer for scalability, and includes a zk-wormhole system modeled on EIP-7503 for private transfers. It is delivered as a Substrate node, runtime, and pallets, dedicated Rust cryptography libraries for the signatures, hashing, and ZK circuits, and a mobile wallet app. Together these aim to offer a full, quantum-resistant environment for holding and transacting digital wealth.

Firelight is an on-chain cover protocol. The contracts implement an upgradeable ERC4626-compatible vault for staked collateral, an off-chain-matched cover order allocation flow, cover receipt NFTs, incident assessment and payout execution, a vault reward distributor, and a Flare FTSO v2 price adapter exposed through a Chainlink AggregatorV3-compatible read surface.

TCG-VAULT is a community ecosystem built around trading card game collectibles, combining physical TCG assets — sealed products and graded cards — with Web3 infrastructure deployed on BNB Chain.

Zendex is a privacy-preserving ZK-AMM, combining zero-knowledge asset management, private swaps, liquidity provisioning, and staking-based fee incentives into a unified DEX protocol.

ENS (Ethereum Name Service) is a distributed, open, and extensible naming system based on the Ethereum blockchain. ENS maps human-readable names like 'alice.eth' to machine-readable identifiers such as Ethereum addresses, other cryptocurrency addresses, content hashes, and metadata. It functions as a decentralized alternative to the traditional DNS, allowing users to replace long, complex wallet addresses with simple, memorable names. Built on a system of smart contracts, ENS supports both the '.eth' top-level domain native to Ethereum and the integration of traditional DNS names. Its architecture is composed of two principal components: the registry, which maintains the record of all domains and their owners, and resolvers, which are responsible for translating names into the corresponding addresses or resources.
