AW-Tool Enso Documentation

The aw-tool-enso package provides utilities for performing onchain actions, such as swap, deposit, lend, borrow, etc. across 180+ protocols.

Files Overview (in src/lib)

1. ipfs.ts

Handles IPFS CIDs for different environments (development, testing, production). Falls back to default CIDs if the build output is not found.

Key Features

• Default CIDs: Predefined CIDs for datil-dev, datil-test, and datil environments
• Dynamic CID Loading: Attempts to load CIDs from dist/ipfs.json at runtime
• Fallback Mechanism: Uses default CIDs if the file is missing or unreadable

2. lit-action.ts

Contains the main logic for executing a Lit Action to perform an Enso route.

Key Features

• PKP Info Retrieval: Fetches PKP details (token ID, Ethereum address, public key) from the PubkeyRouter contract.
• Input Validation: Validates inputs against the policy defined in the PKP Tool Registry.
• Find the best route between 2 tokens: Returns the best possible route between two tokens on specified chain.
• Gas Estimation: Estimates gas limits and fees for the transaction.
• Transaction Creation: Creates and signs the transaction using the PKP public key.
• Broadcasting: Sends the signed transaction to the network.

3. policy.ts

Defines and validates the Enso policy schema using Zod.

Key Features

• Policy Schema: Validates policy fields:
  • type: Must be 'SignEcdsa'
  • version: Policy version string
  • allowedPrefixes: Array of allowed message prefixes
• Encoding/Decoding: Converts policies to and from ABI-encoded strings using ethers
• Type Safety: Uses Zod for schema validation and TypeScript type inference

4. tool.ts

Configures the Enso route for different Lit networks.

Key Features

• Parameter Schema: Validates required parameters:
  • tokenIn
  • tokenOut
  • amountIn
  • chainId
• Network Configuration: Creates network-specific tools for each supported Lit network
• Policy Integartion: Integrates with the EnsoRoutePolicy
