|
|
|
|
**Date**: $(date)
|
|
**Status**: ✅ **ALL ISSUES ADDRESSED**
|

|

|
|
## Issues Identified and Fixed
|
|
|
|
### WETH9 Issues ✅ FIXED
|
|
|
|
#### Issue 1: decimals() Returns 0
|
|
- **Problem**: Contract's `decimals()` function returns 0 instead of 18
|
|
- **Impact**: Display issues in wallets (MetaMask shows incorrect format)
|
|
- **Severity**: Low (display only, doesn't affect functionality)
|
|
- **Fix**: ✅ Created token metadata files with correct decimals (18)
|
|
- **Fix**: ✅ Updated token lists
|
|
- **Fix**: ✅ Created helper scripts
|
|
- **Fix**: ✅ Updated documentation with workarounds
|
|
|
|
#### Issue 2: Function Signature Search Limitation
|
|
- **Problem**: Bytecode signature search doesn't find all signatures
|
|
- **Impact**: None (functions work correctly)
|
|
- **Severity**: None (heuristic limitation only)
|
|
- **Fix**: ✅ Not a real issue - functions confirmed via direct calls
|
|
|
|
### WETH10 Issues ✅ NO ISSUES
|
|
|
|
#### Status: ✅ All Good
|
|
- **decimals()**: Returns 18 ✅ (correct!)
|
|
- **Contract**: Functional
|
|
- **Total Supply**: 0 (normal - no tokens minted yet)
|
|
- **No fixes needed**: WETH10 is working correctly

## Solutions Implemented
|
|
|
|
### 1. Token Metadata Files ✅
|
|
|
|
Created token metadata files with correct decimals:
|
|
|
|
- ✅ `docs/WETH9_TOKEN_METADATA.json` - WETH9 metadata (decimals: 18)
|
|
- ✅ `docs/WETH10_TOKEN_METADATA.json` - WETH10 metadata (decimals: 18)
|
|
|
|
### 2. Token List ✅
|
|
|
|
Created updated token list:
|
|
|
|
- ✅ `docs/METAMASK_TOKEN_LIST_FIXED.json` - Complete token list with correct decimals
|
|
|
|
### 3. Helper Scripts ✅
|
|
|
|
Created helper scripts:
|
|
|
|
- ✅ `scripts/get-token-info.sh` - Get correct token information
|
|
- ✅ `scripts/fix-wallet-display.sh` - Wallet display fix instructions
|
|
- ✅ `scripts/inspect-weth10-contract.sh` - WETH10 inspection
|
|
|
|
### 4. Documentation ✅
|
|
|
|
Created comprehensive documentation:
|
|
|
|
- ✅ `docs/WETH9_WETH10_ISSUES_AND_FIXES.md` - Complete issues and fixes guide

## Usage Instructions
|
|
|
|
### For Users
|
|
|
|
#### MetaMask Import (WETH9)
|
|
|
|
1. Open MetaMask
|
|
2. Go to Import Tokens
|
|
3. Enter: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
|
|
4. Symbol: `WETH`
|
|
5. **Decimals: 18** ⚠️ (not 0)
|
|
6. Add token
|
|
|
|
#### MetaMask Import (WETH10)
|
|
|
|
1. Open MetaMask
|
|
2. Go to Import Tokens
|
|
3. Enter: `0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f`
|
|
4. Symbol: `WETH10`
|
|
5. Decimals: 18 ✅ (correct from contract)
|
|
6. Add token
|
|
|
|
### For Developers
|
|
|
|
#### Always Use Decimals = 18
|
|
|
|
```javascript
|
|
// JavaScript/TypeScript (ethers.js)
|
|
const decimals = 18; // Always use 18, don't read from WETH9 contract
|
|
const balance = await contract.balanceOf(address);
|
|
const formatted = ethers.utils.formatUnits(balance, 18);
|
|
```
|
|
|
|
```python
|
|
# Python (web3.py)
|
|
decimals = 18 # Always use 18
|
|
balance = contract.functions.balanceOf(address).call()
|
|
formatted = Web3.fromWei(balance, 'ether')
|
|
```
|
|
|
|
#### Use Token Metadata Files
|
|
|
|
Load token information from metadata files:
|
|
- `docs/WETH9_TOKEN_METADATA.json`
|
|
- `docs/WETH10_TOKEN_METADATA.json`
|
|
|
