Testing Philosophy

The best way to test DeFi plugins is with small amounts on real networks. Test networks often have reliability issues and don’t reflect real-world conditions.

​
Safe Testing Practices

​
1. Start Small

Always test with minimal amounts first:
  • 0.001 ETH for transfers
  • $1-5 worth of tokens for swaps
  • Smallest viable amounts for bridges

​
2. Test on Low-Cost Chains First

Start testing on chains with low transaction fees:
  • Polygon: ~$0.01 per transaction
  • Base: ~$0.05 per transaction
  • Arbitrum: ~$0.10 per transaction

​
3. Progressive Testing

1. Test basic transfers first
2. Test token transfers
3. Test swaps with small amounts
4. Test bridges last (they're most complex)

Testing Checklist

​
Environment Setup

# Use a dedicated test wallet
EVM_PRIVATE_KEY=test_wallet_private_key

# Start with one chain
ETHEREUM_PROVIDER_BASE=https://base-mainnet.g.alchemy.com/v2/YOUR_KEY

​
Basic Tests

  1. Wallet Connection 
    User: What's my wallet address?
Agent: [Should show your wallet address]
  2. Balance Check 
    User: What's my balance?
Agent: [Should show balances across configured chains]
  3. Small Transfer 
    User: Send 0.001 ETH to [another test address]
Agent: [Should execute the transfer]
  4. Token Transfer 
    User: Send 1 USDC to [test address]
Agent: [Should handle ERC20 transfer]

​
Swap Testing

Test swaps with minimal amounts: 
User: Swap 0.01 ETH for USDC
Agent: [Should find best route and execute]

​
Error Handling

Test error scenarios:
  • Insufficient balance
  • Invalid addresses
  • Network issues
  • High slippage

​
Monitoring Results

  1. Transaction Verification
    • Check block explorers (Etherscan, BaseScan, etc.)
    • Verify transaction status
    • Confirm balances updated
  2. Gas Usage
    • Monitor gas costs
    • Ensure reasonable gas estimates
    • Check for failed transactions

​
Common Issues

​
”Insufficient funds for gas”

  • Ensure you have native tokens for gas
  • Each chain needs its native token (ETH, MATIC, etc.)

​
”Transaction underpriced”

  • RPC may be congested
  • Try alternative RPC endpoints

​
”Nonce too low”

  • Previous transaction may be pending
  • Wait for confirmation or reset nonce

​
Production Readiness

Before using in production:
  1. Test all intended operations
  2. Verify error handling works
  3. Ensure proper logging
  4. Set appropriate gas limits
  5. Configure slippage tolerances
  6. Test with your expected volumes
