​
Overview

The EVM plugin handles DeFi operations through a structured flow: 
User Message → Action Recognition → Parameter Extraction → Execution → Response

​
Transfer Flow

​
1. User Intent

User: Send 0.1 ETH to alice.eth

​
2. Action Recognition

The plugin identifies this as a transfer action based on keywords (send, transfer, pay).

​
3. Parameter Extraction

Using AI, the plugin extracts:
  • Amount: 0.1
  • Token: ETH
  • Recipient: alice.eth (will resolve to address)
  • Chain: Detected from context or defaults

​
4. Execution

  • Validates recipient address
  • Checks balance
  • Builds transaction
  • Estimates gas
  • Sends transaction
  • Waits for confirmation

​
5. Response

Agent: Successfully transferred 0.1 ETH to alice.eth
Transaction: https://etherscan.io/tx/[hash]

​
Swap Flow

​
1. User Intent

User: Swap 1 ETH for USDC

​
2. Route Discovery

  • Queries multiple DEX aggregators (LiFi, Bebop)
  • Compares routes for best output
  • Considers gas costs

​
3. Execution

  • Approves token if needed
  • Executes swap transaction
  • Monitors for completion

​
Bridge Flow

​
1. User Intent

User: Bridge 100 USDC from Ethereum to Base

​
2. Bridge Route

  • Finds available bridge routes
  • Estimates fees and time
  • Selects optimal path

​
3. Multi-Step Execution

  • Source chain transaction
  • Wait for bridge confirmation
  • Destination chain completion

​
Governance Flow

​
Proposal Creation

User: Create a proposal to increase treasury allocation
→ Plugin creates proposal transaction with targets, values, and description

​
Voting

User: Vote FOR on proposal 42
→ Plugin casts vote with correct proposal ID and support value

​
Error Handling

The plugin handles common errors gracefully:
  • Insufficient Balance: Checks before attempting transaction
  • Network Issues: Retries with exponential backoff
  • Invalid Addresses: Validates all addresses before use
  • High Slippage: Warns user if slippage exceeds tolerance

​
Key Features

  1. Natural Language Processing: Understands various ways to express intents
  2. Multi-Chain Support: Automatically handles chain selection
  3. Gas Optimization: Estimates and optimizes gas usage
  4. Safety Checks: Validates all parameters before execution
  5. Real-Time Feedback: Provides transaction status updates
