Haust Network is a cutting-edge Layer-2 solution designed to unlock the full potential of blockchain’s permissionless nature and offer innovative tools for decentralized finance (DeFi). It provides high security, low fees, and a dedicated SDK that simplifies integration with Telegram and other messengers.

Challenge

While decentralized finance offers unparalleled freedom in terms of peer-to-peer transactions, the tech brings about a whole new set of challenges that the Haust Network aims to solve.

Complexity: a lot of DeFi platforms are hard to use and need serious technical know-how, which puts off everyday users.

Fragmented systems: with so many blockchains that don’t work smoothly together, users face inefficiencies and a clunky experience.

High fees: transaction costs, especially on Ethereum, are sky-high, which makes it tough for smaller users to get involved.

Security worries: Smart contract vulnerabilities and susceptibility to flash loan attacks — often due to coding errors, insufficient testing, or inadequate auditing — leave DeFi platforms open to exploits, eroding trust and adoption.

Solution

Innowise was engaged to assist in building Haust Network, a Layer-2 DeFi solution powered by zk-rollups, designed to push forward blockchain ecosystem development. Haust connects different blockchains, boosts liquidity, speeds up transactions, and keeps costs low — all while being secure and easy to use.

Haust Network takes on the biggest challenges in DeFi by creating a complete ecosystem that removes barriers. Cross-chain compatibility makes moving assets between blockchains seamless, improves liquidity, and opens up DeFi to more users. Its smart liquidity solutions help optimize capital, cut slippage, and increase yields.

Here’s a closer look at what powers the network behind the scenes:

Zk-rollups and Polydon zkEVM

The Haust Network strategically integrates zk-rollups and Polygon zkEVM to address two major challenges in DeFi: high transaction costs and scalability issues.

Zero-Knowledge Rollups

As a Layer-2 scaling solution, zk-rollups bundle multiple transactions into one, processing them off-chain and submitting only a concise Zero-Knowledge Proof (ZKP) to the Layer-1 blockchain. This process verifies the validity of all transactions without revealing their details, significantly reduces on-chain data usage, speeds up transaction processing, and cuts fees.

Polygon zkEVM

Polygon zkEVM is an Ethereum-compatible Layer-2 solution that uses zk-rollups to deliver fast and cost-efficient transactions. Acting as a “Zero-Knowledge Ethereum Virtual Machine,” it enables developers to run Ethereum-compatible smart contracts using zero-knowledge proofs. This compatibility allows existing Ethereum applications to migrate to zkEVM with minimal adjustments to make integration with Haust Network seamless and efficient.

AggLayer

AggLayer is a powerful bridge that connects multiple blockchains, making it super easy to move assets across networks. Instead of juggling a bunch of different bridges, users get a single, straightforward way to access cross-chain liquidity.

Using ZK proofs, AggLayer keeps every transaction secure, so you don’t have to worry about safety. It solves the problem of fragmented liquidity and ensures smooth, reliable interactions between blockchains.

AggLayer also lets all connected chains share their TVL (Total Value Locked) to simplify liquidity management. Users can even pay gas fees with HAUST, the network’s native token, which adds extra convenience to the cross-chain operations.

NEAR DA

The NEAR Data Availability Layer adds extra security checks, making things safer and building user trust. It keeps transaction data accessible, even if not stored directly on the main chain, to keep everything transparent for audits.

Efficient block space: NEAR DA makes the most of block space by giving each shard plenty of room to work with;
Optimized storage: every 4MB of space is fully usable, which keeps things efficient and prevents unnecessary cryptographic bloat;
Scalability: NEAR’s resharding feature ensures seamless scaling and keeps data availability ample and affordable.

Account Abstraction

Account Abstraction lets users use smart contracts as their accounts, making things more flexible and secure. It is key to the Haust Network, transforming the Haust Wallet experience with features like Web2-style sign-in, keyless wallet management, social recovery, and smart gas fee handling.

Authorization controls: with account abstraction, users can set up custom permissions for their accounts, like requiring multiple signatures, adding time locks, or setting transfer limits. It also lets users restrict access to specific smart contracts for extra security;
Fee sponsorship: account abstraction lets a "paymaster" cover gas fees for users, so there’s no need to pre-fund transactions. This makes using blockchain services easier and removes the need to hold native tokens in Smart Contract Accounts (SCAs);
Flexible fee payments: instead of paying gas fees only in ETH, users can use any ERC-20 token, like stablecoins or HAUST. This makes transactions more convenient and flexible;
Pull transactions: users can set up automated payments and let third parties pull funds on a schedule. It’s like setting up a subscription, bringing familiar Web2-style payments into Web3;
Batch transactions: with account abstraction, users can bundle multiple approvals into a single transaction. This saves time and makes tasks like swapping tokens faster and less repetitive;
Wallet recovery: account abstraction supports social recovery, allowing users to regain access to their accounts through trusted contacts. It’s a user-friendly alternative to traditional wallet recovery methods.

Haustoria protocol

Haustoria is a smart contract system that links up with different DeFi protocols across multiple networks. It automatically puts your liquidity to work as collateral and shares the profits back with you as native yield.

Diversified staking: Haustoria opens up staking opportunities across multiple blockchains and connects users to the most reliable and high-yield projects out there. Instead of keeping all your liquidity in one spot, it helps you spread it out to maximize earnings by tapping into profitable staking options across the ecosystem;
Yield optimization: Haustoria takes the hassle out of staking by managing the most liquid and profitable opportunities. No need to search or switch options manually — it ensures you get the best performance and returns without the extra effort;
Integration opportunities: Haustoria easily integrates with new protocols offering attractive APYs, such as those on the TON network, as long as they meet safety and reliability standards. This flexibility makes Haust Network work like a decentralized hedge fund, while the Haust Wallet acts as an all-in-one tool for managing your DeFi portfolio.

Haust Wallet

The Haust Wallet is a secure, EVM-compatible wallet designed for effortless asset management across multiple chains. It offers innovative features like social recovery, keyless wallet access, multi-chain gas payments, and even a Telegram mini app for added convenience.

By integrating a decentralized exchange (DEX) based on Uniswap v3, the wallet provides advanced trading tools and improved liquidity management directly within the platform. When users deposit assets, the wallet issues hTokens (Rebase-tokens), which come with an investment component. These tokens allow users to interact with the Haust blockchain ecosystem, adding extra value to their holdings while simplifying their DeFi experience.
