Building DeFi Applications with Aspens Markets Stack¶

Cross-Chain DeFi Applications¶

Aspens Markets Stack lets you build DeFi applications that work across multiple blockchains. This opens up new possibilities that weren't feasible when blockchains operated in isolation.

Here are some real-world applications you can build:

Application Types¶

Cross-Chain Liquidity Aggregators¶

Find the best prices across multiple blockchains at once. For example, your app could scan Ethereum, Arbitrum, and Polygon simultaneously to get USDC at the best rate, regardless of where your user's assets are stored.

Multi-Chain Yield Optimizers¶

Help users earn more by moving their assets to where yields are highest. Your app could automatically shift stablecoins from Ethereum to Solana when yields are 2% higher there, then move them back when the situation changes.

Cross-Chain Collateralized Lending¶

Let users deposit ETH on Ethereum as collateral and borrow USDC on Polygon without having to bridge assets first. This creates more flexible lending options and better capital efficiency.

Inter-Blockchain DEX Aggregators¶

Build a trading interface that checks prices across chains before executing. If a user wants to buy AVAX with USDT, your app could compare rates on both Avalanche and Ethereum before making the trade.

Tokenized Asset Bridges¶

Create specialized bridges for specific assets. For instance, a bridge that handles real estate tokens with built-in compliance checks when moving between regulatory environments on different chains.

Cross-Chain Portfolio Management¶

Build dashboards where users can view and manage all their assets across different blockchains. Include features to rebalance portfolios by trading directly between chains without using traditional bridges.

How to Start Building¶

To build your first cross-chain app with Aspens:

For Developers: Check out the Application Developer Guide for APIs, code samples, and integration steps. The guide includes examples in TypeScript and Rust.
For Platform Operators: If you want to run your own Aspens Markets Stack, follow the Operator Guide for setup and maintenance instructions.

Why Build on Aspens?¶

Users Control Their Assets: No custodial risks - users' funds remain in smart contracts they can verify
Simple Multi-Chain Integration: One API connects you to multiple blockchains
Familiar Trading Model: Standard orderbook matching that professional traders understand
Verifiable Trades: Every transaction is recorded on both blockchains involved
Works With Other Protocols: Combine with existing DeFi protocols on multiple chains

Example and Resources¶

We've moved our detailed trading example to the Core Concepts section. It walks through how Alice trades USDT on Ethereum for USDC on Hedera, showing exactly how the process works under the hood.

By using Aspens, you can build applications that break down the walls between blockchain networks, giving users more options, better prices, and new financial opportunities.
