Protocol Abstraction Layer

The DeFi Protocol Landscape

The DeFi ecosystem is a vibrant but complex landscape of protocols, each with its own unique interfaces, parameters, and operational models. From lending platforms to decentralized exchanges and liquid staking solutions, each protocol has developed its own way of handling transactions, managing positions, and interacting with users.

This diversity, while fostering innovation, creates significant complexity. Each protocol requires specific knowledge of its interfaces, parameters, and operational nuances. For AI agents and developers, this means learning and maintaining multiple integration points, handling different error cases, and managing protocol-specific quirks.

Universal DeFAI Language

edwin introduces a universal language for DeFAI operations, transforming complex protocol-specific interactions into simple, standardized commands. This abstraction layer acts as a universal translator, allowing AI agents to speak one language while interacting with any supported DeFi protocol.

Example: Supply Command

// Execute supply operation
await edwin.plugins.aave?.supply.execute({
    chain: 'base',
    amount: 100,
    asset: 'usdc'
});

In this example, the same simple command structure works seamlessly across different lending protocols, despite their underlying differences in implementation.

Protocol Categories Made Simple

Lending & Borrowing

edwin standardizes core lending operations through plugins:

• supply: Supply assets to Aave

• withdraw: Withdraw from Aave

• borrow: Borrow from Aave

Whether you're interacting with established lending markets or innovative new platforms, the commands remain consistent and intuitive.

Trading & Liquidity

For decentralized exchanges and liquidity protocols:

• swap: Swap tokens on Uniswap

• addLiquidity: Add liquidity to Uniswap

• removeLiquidity: Remove liquidity from Uniswap

One set of commands works across various DEX designs and liquidity pool structures.

Staking & Yield

Standardized operations for yield generation:

• stake: Stake ETH on Lido

• unstake: Unstake from Lido

• claimRewards: Claim rewards from Lido

Multichain by Design

Protocol abstraction in edwin extends across multiple blockchain networks. The same commands work consistently across different chains, abstracting away the complexity of:

• Chain-specific transaction formats

• Different consensus mechanisms

• Varying gas models

• Network-specific parameters

Example: Multichain Operation

// Supply USDC on Base
await edwin.plugins.aave?.supply.execute({
    chain: 'base',
    amount: 100,
    asset: 'usdc'
});

// Supply USDC on Solana
await edwin.plugins.lulo?.supply.execute({
    chain: 'solana',
    amount: 100,
    asset: 'usdc'
});

Security Through Standardization

Protocol abstraction enhances security through standardization. edwin's protocol whitelisting approach ensures that:

• Only vetted and audited protocols can be integrated

• Operations follow predefined safety boundaries

• Transactions are validated consistently

• Risk parameters are standardized across protocols

This standardization creates a secure foundation for AI agents to interact with DeFi protocols, reducing the risk of errors and ensuring predictable behavior across the entire DeFi landscape.
