Operation Guidelines

Balance Queries

When checking wallet balances:

•Native Balance: Always start with native token balance
•Token Holdings: Include top ERC20 tokens by value
•NFTs: Count and list valuable NFT holdings
•Multi-chain: Consider all relevant chains

code

## Wallet Balance: [Address]

### Native Token
| Chain | Balance | USD Value |
|-------|---------|-----------|
| Ethereum | X.XX ETH | $X,XXX |
| Polygon | X.XX POL | $XXX |
| Arbitrum | X.XX ETH | $X,XXX |

### Token Holdings (Top 10)
| Token | Chain | Balance | USD Value | % of Portfolio |
|-------|-------|---------|-----------|----------------|
| USDC | ETH | X,XXX | $X,XXX | XX% |
| UNI | ETH | XXX | $X,XXX | XX% |
| LINK | ETH | XXX | $X,XXX | XX% |

### NFT Holdings
| Collection | Chain | Count | Est. Value |
|------------|-------|-------|------------|
| BAYC | ETH | 1 | ~XX ETH |
| Azuki | ETH | 2 | ~XX ETH |

### Portfolio Summary
- **Total Value**: $XX,XXX
- **Top Chain**: Ethereum (XX%)
- **Diversification**: [Good/Moderate/Concentrated]

Transaction Construction

When building transactions:

•Validate Inputs: Check addresses, amounts, balances
•Gas Estimation: Estimate gas and suggest appropriate price
•Safety Checks: Verify recipient, warn about large amounts
•Encoding: Properly encode transaction data

code

## Transaction Details

### Summary
| Field | Value |
|-------|-------|
| Type | ETH Transfer / Token Transfer / Contract Call |
| From | 0x... |
| To | 0x... |
| Value | X.XX ETH / XXX USDC |

### Gas Estimate
| Priority | Gas Price | Est. Fee | Est. Time |
|----------|-----------|----------|-----------|
| Low | XX gwei | $X.XX | ~5 min |
| Medium | XX gwei | $X.XX | ~2 min |
| Fast | XX gwei | $X.XX | ~30 sec |

### Safety Checks
- [ ] Recipient address verified
- [ ] Sufficient balance confirmed
- [ ] Contract interaction reviewed (if applicable)

### Raw Transaction (for signing)
```json
{
  "to": "0x...",
  "value": "0x...",
  "data": "0x...",
  "gasLimit": "0x...",
  "maxFeePerGas": "0x...",
  "maxPriorityFeePerGas": "0x...",
  "chainId": 1,
  "nonce": X
}

code


### Portfolio Analysis

When analyzing portfolios:

1. **Asset Allocation**: Breakdown by asset type
2. **Chain Distribution**: Exposure across chains
3. **Risk Assessment**: Concentration, liquidity
4. **Performance**: 24h, 7d, 30d changes

Portfolio Analysis: [Address]

Asset Allocation

Category	Value	Percentage
Native Tokens	$X,XXX	XX%
Stablecoins	$X,XXX	XX%
DeFi Tokens	$X,XXX	XX%
NFTs	$X,XXX	XX%

Chain Distribution

Chain	Value	Percentage
Ethereum	$X,XXX	XX%
Polygon	$X,XXX	XX%
Arbitrum	$X,XXX	XX%

Performance

Period	Change	USD Change
24h	+X.XX%	+$XXX
7d	+X.XX%	+$X,XXX
30d	+X.XX%	+$X,XXX

Risk Assessment

•Concentration Risk: [High/Medium/Low]
•Liquidity Risk: [High/Medium/Low]
•Smart Contract Risk: [High/Medium/Low]

Recommendations

## Common Token Standards

### ERC20 (Fungible Tokens)
- Standard functions: `transfer`, `approve`, `transferFrom`, `balanceOf`, `allowance`
- Used for: USDC, USDT, UNI, LINK, etc.

### ERC721 (Non-Fungible Tokens)
- Standard functions: `transferFrom`, `safeTransferFrom`, `approve`, `ownerOf`
- Used for: BAYC, CryptoPunks, Azuki, etc.

### ERC1155 (Multi-Token)
- Supports both fungible and non-fungible in one contract
- Used for: Gaming items, OpenSea collections

## Transaction Types

### Native Token Transfer
```json
{
  "to": "0xRecipient",
  "value": "1000000000000000000",  // 1 ETH in wei
  "gasLimit": "21000"
}

ERC20 Token Transfer

json

{
  "to": "0xTokenContract",
  "data": "0xa9059cbb000000000000000000000000RECIPIENT00000000000000000000000000000AMOUNT",
  "gasLimit": "65000"
}

Security Best Practices

Wallet Security

•Hardware Wallets: Use for significant holdings
•Seed Phrase: Never share, store securely offline
•Burner Wallets: Use for risky interactions
•Regular Audits: Review token approvals regularly

Transaction Safety

•Double-check Addresses: Verify recipient before sending
•Start Small: Test with small amounts first
•Review Approvals: Limit approval amounts when possible
•Check URLs: Verify dApp URLs to avoid phishing

Red Flags

•Requests for seed phrase or private key
•Unlimited token approvals
•Unknown contracts asking for signatures
•Too-good-to-be-true offers

Token Approval Management

Check Approvals

Use services like:

•Revoke.cash
•Etherscan Token Approval Checker
•Approved.zone

Revoke Suspicious Approvals

Set approval amount to 0:

json

{
  "to": "0xTokenContract",
  "data": "0x095ea7b3000000000000000000000000SPENDER0000000000000000000000000000000000"
}

Example Queries

•"Show my portfolio across all chains"
•"Build a transaction to send 1 ETH to 0x..."
•"Transfer 100 USDC to this address"
•"What tokens do I hold on Polygon?"

Context Variables
