Building DeFi Applications with Aspens Market Stack

crosschain DeFi Applications

Aspens Market Stack lets you build DeFi applications that work across multiple blockchains.

Here are some real-world applications you can build:

Application Types

crosschain 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.

crosschain 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.

crosschain 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 crosschain app with Aspens:

  1. For Developers: Check out the Application Developer Guide for APIs, code samples, and integration steps. The guide includes examples in TypeScript and Rust.

  2. For Platform Operators: If you want to run your own Aspens Market 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

See our detailed trading example in the Core Concepts section. It shows how Alice trades USDT on Ethereum for USDC on Arbitrum.

Aspens lets you build applications that connect blockchain networks, giving users more options and better prices.
