# Challenger Operations Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide explains how to become a challenger and detect fraudulent claims in the trustless bridge system. Challengers monitor claims and submit fraud proofs to earn rewards.
|
||||
|
||||
## Becoming a Challenger
|
||||
|
||||
### Requirements
|
||||
|
||||
1. **Ethereum Wallet**: Wallet with ETH for gas fees
|
||||
2. **Monitoring Infrastructure**: Ability to monitor both ChainID 138 and Ethereum Mainnet
|
||||
3. **Technical Knowledge**: Understanding of fraud proofs, Merkle proofs, and bridge mechanics
|
||||
4. **Capital**: ETH for gas fees (rewards cover costs if successful)
|
||||
|
||||
### Setup Steps
|
||||
|
||||
1. **Deploy Monitoring Service**:
|
||||
- Monitor `Deposit` events on ChainID 138
|
||||
- Monitor `ClaimSubmitted` events on Ethereum Mainnet
|
||||
- Compare claims against source chain state
|
||||
|
||||
2. **Prepare Fraud Proof Generation**:
|
||||
- Set up Merkle proof generation
|
||||
- Implement fraud proof encoding
|
||||
- Test fraud proof verification
|
||||
|
||||
3. **Test on Testnet**:
|
||||
- Test challenge submission
|
||||
- Verify fraud proof format
|
||||
- Practice fraud detection
|
||||
|
||||
## Challenger Operations
|
||||
|
||||
### Monitoring for Fraud
|
||||
|
||||
**What to Monitor**:
|
||||
1. **Claims on Ethereum**: All `ClaimSubmitted` events
|
||||
2. **Deposits on ChainID 138**: All `Deposit` events
|
||||
3. **Compare**: Verify claims match deposits
|
||||
|
||||
**Fraud Detection**:
|
||||
- **Non-Existent Deposit**: Claim for deposit that doesn't exist
|
||||
- **Incorrect Amount**: Claim amount differs from actual deposit
|
||||
- **Incorrect Recipient**: Claim recipient differs from actual deposit
|
||||
- **Double Spend**: Same deposit claimed twice
|
||||
|
||||
### Submitting Challenges
|
||||
|
||||
**Function**: `ChallengeManager.challengeClaim()`
|
||||
|
||||
**Parameters**:
|
||||
- `depositId`: Deposit ID of the claim to challenge
|
||||
- `proofType`: Type of fraud proof (NonExistentDeposit, IncorrectAmount, etc.)
|
||||
- `proof`: Encoded fraud proof data
|
||||
|
||||
**Process**:
|
||||
```solidity
|
||||
// Generate fraud proof
|
||||
bytes memory fraudProof = generateFraudProof(depositId, claim, proofType);
|
||||
|
||||
// Submit challenge
|
||||
challengeManager.challengeClaim(
|
||||
depositId,
|
||||
proofType,
|
||||
fraudProof
|
||||
);
|
||||
```
|
||||
|
||||
**Fraud Proof Types**:
|
||||
1. **NonExistentDeposit**: Merkle proof showing deposit doesn't exist
|
||||
2. **IncorrectAmount**: Merkle proof with actual deposit amount
|
||||
3. **IncorrectRecipient**: Merkle proof with actual recipient
|
||||
4. **DoubleSpend**: Proof of previous claim for same deposit
|
||||
|
||||
### Fraud Proof Generation
|
||||
|
||||
**Non-Existent Deposit Proof**:
|
||||
1. Get state root from ChainID 138 block
|
||||
2. Hash claimed deposit data
|
||||
3. Generate Merkle proof showing non-existence
|
||||
4. Encode proof according to `FraudProofTypes.NonExistentDepositProof`
|
||||
|
||||
**Incorrect Amount Proof**:
|
||||
1. Get actual deposit from ChainID 138
|
||||
2. Generate Merkle proof for actual deposit
|
||||
3. Encode proof with actual amount
|
||||
4. Submit challenge with proof
|
||||
|
||||
**See**: `docs/bridge/trustless/FRAUD_PROOFS.md` for detailed proof formats
|
||||
|
||||
## Economics
|
||||
|
||||
### Costs
|
||||
|
||||
- **Gas Fees**: For submitting challenges

||||
|
||||
### Revenue
|
||||
|
||||
- **Challenger Reward**: 50% of slashed bond
|
||||
- **Example**: If bond is 1.1 ETH, challenger receives 0.55 ETH
|
||||
|
||||
### Profitability
|
||||
|
||||
- Calculate: Reward - Gas Costs - Infrastructure - Time
|
||||
- Consider success rate, gas prices, bond amounts

# Liquidity Provider Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide explains how to become a liquidity provider (LP) for the trustless bridge system. LPs provide liquidity to enable near-instant bridge releases while claims are being finalized.
|
||||
|
||||
## Becoming a Liquidity Provider
|
||||
|
||||
### Requirements
|
||||
|
||||
1. **Capital**: ETH or WETH to provide as liquidity
|
||||
2. **Risk Tolerance**: Understand liquidity risks
|
||||
3. **Technical Knowledge**: Understanding of bridge mechanics and liquidity pools
|
||||
|
||||
### Setup Steps
|
||||
|
||||
1. **Understand Risks**:
|
||||
- Review liquidity pool mechanics
|
||||
- Understand minimum liquidity ratio
|
||||
- Assess withdrawal restrictions
|
||||
- Review fee structure
|
||||
|
||||
2. **Prepare Capital**:
|
||||
- Decide on amount to provide
|
||||
- Choose asset type (ETH or WETH)
|
||||
- Ensure sufficient balance
|
||||
|
||||
3. **Test on Testnet**:
|
||||
- Test providing liquidity
|
||||
- Test withdrawals
|
||||
- Verify fee collection
|
||||
- Practice procedures
|
||||
|
||||
## LP Operations
|
||||
|
||||
### Providing Liquidity
|
||||
|
||||
**Function**: `LiquidityPoolETH.provideLiquidity()` or `depositWETH()`
|
||||
|
||||
**For ETH**:
|
||||
```solidity
|
||||
liquidityPool.provideLiquidity{value: amount}(LiquidityPoolETH.AssetType.ETH);
|
||||
```
|
||||
|
||||
**For WETH**:
|
||||
```solidity
|
||||
// First approve WETH
|
||||
weth.approve(address(liquidityPool), amount);
|
||||
// Then deposit
|
||||
liquidityPool.depositWETH(amount);
|
||||
```
|
||||
|
||||
**Process**:
|
||||
1. Approve tokens (for WETH)
|
||||
2. Call provide function with amount
|
||||
3. Receive LP shares (1:1 with deposit)
|
||||
4. Start earning fees
|
||||
|
||||
### Withdrawing Liquidity
|
||||
|
||||
**Function**: `LiquidityPoolETH.withdrawLiquidity()`
|
||||
|
||||
**Process**:
|
||||
```solidity
|
||||
liquidityPool.withdrawLiquidity(amount, assetType);
|
||||
```
|
||||
|
||||
**Restrictions**:
|
||||
- Withdrawals blocked if below minimum liquidity ratio (110%)
|
||||
- Must maintain: `availableLiquidity >= pendingClaims * 1.1`
|
||||
- Check before withdrawing
|
||||
|
||||
**Check Availability**:
|
||||
```solidity
|
||||
(bool canWithdraw, string memory reason) = canWithdraw(amount, assetType);
|
||||
```
|
||||
|
||||
### Fee Collection
|
||||
|
||||
**Fee Structure**:
|
||||
- LP fee: 5 bps (0.05%) on bridge amount
|
||||
- Fees remain in pool (increase effective liquidity)
|
||||
- Distributed proportionally to LP shares
|
||||
|
||||
**Fee Calculation**:
|
||||
- Fee = bridgeAmount * 0.0005
|
||||
- Fees increase pool value
|
||||
- LPs benefit from fee accumulation
|
||||
|
||||
## Economics
|
||||
|
||||
### Revenue
|
||||
|
||||
- **LP Fees**: 0.05% of bridge amounts
|
||||
- **Fee Distribution**: Proportional to LP share
|
||||
- **Example**: If pool processes 100 ETH, fees = 0.05 ETH
|
||||
|
||||
### Costs
|
||||
|
||||
- **Opportunity Cost**: Capital locked in pool
|
||||
- **Gas Fees**: For deposits and withdrawals
|
||||
- **Risk**: Liquidity risk, withdrawal restrictions
|
||||
|
||||
### Profitability
|
||||
|
||||
- Calculate: Fees Earned - Opportunity Cost - Gas Costs - Risk
|
||||
- Consider pool utilization, fee rates, capital efficiency
|
||||
- Monitor pool performance
|
||||
|
||||
## Risk Management
|
||||
|
||||
### Liquidity Risks
|
||||
|
||||
1. **Withdrawal Restrictions**:
|
||||
- Cannot withdraw if below minimum ratio
|
||||
- May need to wait for claims to finalize
|
||||
- Plan withdrawals accordingly
|
||||
|
||||
2. **Capital Lockup**:
|
||||
- Capital locked in pool
|
||||
- Limited withdrawal flexibility
|
||||
- Consider liquidity needs
|
||||
|
||||
3. **Pool Utilization**:
|
||||
- Low utilization = lower fees
|
||||
- High utilization = higher fees but more risk
|
||||
- Monitor utilization rates
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Diversification**: Don't put all capital in one pool
|
||||
2. **Monitoring**: Monitor pool status regularly
|
||||
3. **Withdrawal Planning**: Plan withdrawals in advance
|
||||
4. **Risk Assessment**: Assess risks before providing liquidity
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Key Metrics
|
||||
|
||||
- **Total Liquidity**: Amount in pool
|
||||
- **Pending Claims**: Amount locked in pending claims
|
||||
- **Available Liquidity**: Total - Pending
|
||||
- **Liquidity Ratio**: Available / Pending
|
||||
- **Fees Earned**: Total fees collected
|
||||
- **LP Share**: Your share of pool
|
||||
|
||||
### Monitoring Functions
|
||||
|
||||
```solidity
|
||||
// Get pool statistics
|
||||
(uint256 total, uint256 pending, uint256 available) =
|
||||
liquidityPool.getPoolStats(assetType);
|
||||
|
||||
// Get your LP share
|
||||
uint256 share = liquidityPool.getLpShare(yourAddress, assetType);
|
||||
|
||||
// Get available liquidity
|
||||
uint256 available = liquidityPool.getAvailableLiquidity(assetType);
|
||||
```
|
||||
|
||||
### Alerts
|
||||
|
||||
- **Low Liquidity Ratio**: Alert when ratio approaches minimum
|
||||
- **High Utilization**: Alert on high pool utilization
|
||||
- **Withdrawal Blocked**: Alert when withdrawals are blocked
|
||||
- **Fee Accumulation**: Track fee earnings
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Capital Management
|
||||
|
||||
- **Adequate Capital**: Provide sufficient capital for efficiency
|
||||
- **Reserve Funds**: Keep reserves outside pool
|
||||
- **Diversification**: Diversify across asset types
|
||||
- **Rebalancing**: Rebalance as needed
|
||||
|
||||
### 2. Risk Management
|
||||
|
||||
- **Monitor Ratios**: Monitor liquidity ratios regularly
|
||||
- **Plan Withdrawals**: Plan withdrawals in advance
|
||||
- **Understand Restrictions**: Understand withdrawal restrictions
|
||||
- **Assess Risks**: Continuously assess risks
|
||||
|
||||
### 3. Optimization
|
||||
|
||||
- **Fee Maximization**: Optimize for fee earnings

||||
|
||||
- **Check Ratio**: Verify liquidity ratio
|
||||
- **Wait**: Wait for claims to finalize
|
||||
- **Reduce Amount**: Try smaller withdrawal
|
||||
- **Monitor**: Monitor pool status
|
||||
|
||||
### Low Fees

# Relayer Operations Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide explains how to become a relayer and operate the trustless bridge system. Relayers monitor deposits on ChainID 138 and submit claims on Ethereum Mainnet.
|
||||
|
||||
## Becoming a Relayer
|
||||
|
||||
### Requirements
|
||||
|
||||
1. **Ethereum Wallet**: Wallet with ETH for gas fees and bonds
|
||||
2. **Monitoring Infrastructure**: Ability to monitor ChainID 138 events
|
||||
3. **Sufficient Capital**: ETH for posting bonds (110% of deposit amount, minimum 1 ETH)
|
||||
4. **Technical Knowledge**: Understanding of blockchain, smart contracts, and bridge mechanics
|
||||
|
||||
### Setup Steps
|
||||
|
||||
1. **Deploy Monitoring Service**:
|
||||
- Set up event monitoring for `Lockbox138` on ChainID 138
|
||||
- Monitor `Deposit` events
|
||||
- Track deposit IDs and details
|
||||
|
||||
2. **Prepare Bond Capital**:
|
||||
- Ensure sufficient ETH balance
|
||||
- Calculate bond requirements: `bond = max(depositAmount * 1.1, 1 ETH)`
|
||||
- Maintain reserve for multiple concurrent claims
|
||||
|
||||
3. **Test on Testnet**:
|
||||
- Deploy to testnet first
|
||||
- Test claim submission
|
||||
- Verify bond posting and release
|
||||
- Practice emergency procedures
|
||||
|
||||
## Relayer Operations
|
||||
|
||||
### Monitoring Deposits
|
||||
|
||||
**Event to Monitor**: `Deposit` event from `Lockbox138` contract
|
||||
|
||||
**Event Structure**:
|
||||
```solidity
|
||||
event Deposit(
|
||||
uint256 indexed depositId,
|
||||
address indexed asset,
|
||||
uint256 amount,
|
||||
address indexed recipient,
|
||||
bytes32 nonce,
|
||||
address depositor,
|
||||
uint256 timestamp
|
||||
);
|
||||
```
|
||||
|
||||
**Monitoring Process**:
|
||||
1. Listen for `Deposit` events on ChainID 138
|
||||
2. Extract deposit details (depositId, asset, amount, recipient)
|
||||
3. Verify deposit is legitimate
|
||||
4. Calculate required bond
|
||||
5. Submit claim on Ethereum Mainnet
|
||||
|
||||
### Submitting Claims
|
||||
|
||||
**Function**: `InboxETH.submitClaim()`
|
||||
|
||||
**Parameters**:
|
||||
- `depositId`: Deposit ID from ChainID 138
|
||||
- `asset`: Asset address (address(0) for native ETH)
|
||||
- `amount`: Deposit amount
|
||||
- `recipient`: Recipient address on Ethereum
|
||||
- `proof`: Optional proof data (reserved for future light client)
|
||||
|
||||
**Process**:
|
||||
```solidity
|
||||
// Calculate required bond
|
||||
uint256 requiredBond = bondManager.getRequiredBond(amount);
|
||||
|
||||
// Submit claim with bond
|
||||
inbox.submitClaim{value: requiredBond}(
|
||||
depositId,
|
||||
asset,
|
||||
amount,
|
||||
recipient,
|
||||
""
|
||||
);
|
||||
```
|
||||
|
||||
**Gas Optimization**:
|
||||
- Batch multiple claims if possible
|
||||
- Use optimal gas prices
|
||||
- Monitor gas price trends
|
||||
- Consider Layer 2 for lower costs
|
||||
|
||||
### Bond Management
|
||||
|
||||
**Bond Requirements**:
|
||||
- Bond = max(depositAmount * 1.1, 1 ETH)
|
||||
- Bond is locked until claim is finalized or challenged
|
||||
- If challenged and fraud proven, bond is slashed (50% to challenger, 50% burned)
|
||||
- If not challenged, bond is released after finalization
|
||||
|
||||
**Best Practices**:
|
||||
- Maintain sufficient bond capital
|
||||
- Monitor bond utilization
|
||||
- Track bond release times
|
||||
- Plan for bond requirements
|
||||
|
||||
### Claim Finalization
|
||||
|
||||
**Process**:
|
||||
1. Wait for challenge window to expire (30 minutes default)
|
||||
2. Call `ChallengeManager.finalizeClaim(depositId)`
|
||||
3. Release bond via `BondManager.releaseBond(depositId)`
|
||||
4. Funds are available in liquidity pool for recipient
|
||||
|
||||
**Automation**:
|
||||
- Set up automated finalization
|
||||
- Monitor challenge window expiration
|
||||
- Automate bond release
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Security
|
||||
|
||||
- **Verify Deposits**: Always verify deposits exist on source chain
|
||||
- **Monitor Challenges**: Watch for challenges to your claims
|
||||
- **Bond Management**: Never submit claims without sufficient bond
|
||||
- **Private Keys**: Secure private keys, use hardware wallets
|
||||
|
||||
### 2. Performance
|
||||
|
||||
- **Fast Submission**: Submit claims quickly to be first relayer
|
||||
- **Gas Optimization**: Optimize gas usage
|
||||
- **Monitoring**: Efficient event monitoring
|
||||
- **Automation**: Automate routine tasks
|
||||
|
||||
### 3. Risk Management
|
||||
|
||||
- **Bond Sizing**: Understand bond requirements
|
||||
- **Fraud Risk**: Only submit legitimate claims
|
||||
- **Liquidity Risk**: Monitor liquidity pool status
|
||||
- **Gas Risk**: Monitor gas prices
|
||||
|
||||
## Economics
|
||||
|

||||
- **First Mover**: Being first relayer may provide advantages
|
||||
|
||||
### Profitability
|
||||
|
||||
- Calculate: Revenue - Costs - Risk
|
||||
- Consider gas prices, bond requirements, competition
|
||||
- Monitor market conditions
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Claim Rejected
|
||||
|
||||
- **Check Bond**: Ensure sufficient bond posted
|
||||

|
||||
|
||||
## Step-by-Step Manual Process
|
||||
|
||||
### Step 1: Wrap ETH to WETH9
|
||||
|
||||
```bash
|
||||
AMOUNT_WEI=$(cast --to-wei 20000 ether)
|
||||
|
||||
cast send "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" \
|
||||
"deposit()" \
|
||||
--value "$AMOUNT_WEI" \
|
||||
--rpc-url http://192.168.11.250:8545 \
|
||||
--private-key 0x... \
|
||||
--gas-price 20000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
### Step 2: Approve Bridge
|
||||
|
||||
```bash
|
||||
MAX_UINT256="115792089237316195423570985008687907853269984665640564039457584007913129639935"
|
||||
|
||||
cast send "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" \
|
||||
"approve(address,uint256)" \
|
||||
"0x89dd12025bfCD38A168455A44B400e913ED33BE2" \
|
||||
"$MAX_UINT256" \
|
||||
--rpc-url http://192.168.11.250:8545 \
|
||||
--private-key 0x... \
|
||||
--gas-price 20000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
### Step 3: Bridge to Ethereum Mainnet
|
||||
|
||||
```bash
|
||||
RECIPIENT="0xYourMainnetAddress"
|
||||
ETHEREUM_SELECTOR="5009297550715157269"
|
||||
AMOUNT_WEI=$(cast --to-wei 20000 ether)
|
||||
|
||||
cast send "0x89dd12025bfCD38A168455A44B400e913ED33BE2" \
|
||||
"sendCrossChain(uint64,address,uint256)" \
|
||||
"$ETHEREUM_SELECTOR" \
|
||||
"$RECIPIENT" \
|
||||
"$AMOUNT_WEI" \
|
||||
--rpc-url http://192.168.11.250:8545 \
|
||||
--private-key 0x... \
|
||||
--gas-price 20000000000 \
|
||||
--legacy
|
||||
```
|
||||

|
||||
## Verification
|
||||
|
||||
### Check WETH9 Balance (Chain 138)
|
||||
|
||||
```bash
|
||||
cast call "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" \
|
||||
"balanceOf(address)" \
|
||||
"0xYourAddress" \
|
||||
--rpc-url http://192.168.11.250:8545
|
||||
```
|
||||
|
||||
### Check Bridge Allowance
|
||||
|
||||
```bash
|
||||
cast call "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" \
|
||||
"allowance(address,address)" \
|
||||
"0xYourAddress" \
|
||||
"0x89dd12025bfCD38A168455A44B400e913ED33BE2" \
|
||||
--rpc-url http://192.168.11.250:8545
|
||||
```
|
||||
|
||||
### Check WETH9 Balance (Ethereum Mainnet)
|
||||
|
||||
After bridge completes (wait 1-5 minutes):
|
||||
|
||||
```bash
|
||||
cast call "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" \
|
||||
"balanceOf(address)" \
|
||||
"0xYourMainnetAddress" \
|
||||
--rpc-url https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY
|
||||
```
|
||||

|
||||
|
||||
## Safety Considerations
|
||||
|
||||
### Large Amount Warnings
|
||||
|
||||
For amounts > 1,000 ETH, the script will:
|
||||
- Display warning messages
|
||||
- Request confirmation before wrapping
|
||||
- Request final confirmation before bridging
|
||||
|
||||
### Gas Fees
|
||||
|
||||
- **Wrap Transaction**: ~50,000 gas
|
||||
- **Approve Transaction**: ~50,000 gas
|
||||
- **Bridge Transaction**: ~200,000-500,000 gas
|
||||
- **CCIP Fees**: Paid in LINK tokens (0.1-2 LINK typically)
|
||||
|
||||
### Timing
|
||||
|
||||
- **Wrap**: ~15 seconds (block confirmation)
|
||||
- **Approve**: ~10 seconds (block confirmation)
|
||||
- **Bridge**: ~1-5 minutes (CCIP confirmation)
|
||||

## Troubleshooting
|
||||
|
||||
### Insufficient ETH Balance
|
||||
|
||||
```
|
||||
Error: Insufficient ETH balance
|
||||
```
|
||||
|
||||
**Solution**: Ensure you have enough ETH to cover:
|
||||
- Amount to wrap
|
||||
- Gas fees for all transactions
|
||||
|
||||
### Insufficient LINK Balance
|
||||
|
||||
```
|
||||
Warning: Low LINK balance
|
||||
```
|
||||
|
||||
**Solution**: Acquire LINK tokens on Chain 138 for CCIP fees
|
||||
|
||||
### Bridge Transaction Fails
|
||||
|
||||
**Possible Causes**:
|
||||
1. Destination not configured on bridge
|
||||
2. Insufficient LINK for fees
|
||||
3. Insufficient gas
|
||||
|
||||
**Solution**: Check bridge destination configuration:
|
||||
|
||||
```bash
|
||||
cast call "0x89dd12025bfCD38A168455A44B400e913ED33BE2" \
|
||||
"destinations(uint64)" \
|
||||
"5009297550715157269" \
|
||||
--rpc-url http://192.168.11.250:8545
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Example: Bridge 20,000 ETH
|
||||
|
||||
```bash
|
||||
# Set environment
|
||||
export PRIVATE_KEY=0xYourPrivateKey
|
||||
export RPC_URL_138=http://192.168.11.250:8545
|
||||
|
||||
# Execute bridge
|
||||
./scripts/wrap-and-bridge-weth9-to-mainnet.sh 20000 0xYourMainnetAddress
|
||||
|
||||
# The script will:
|
||||
# 1. Check ETH balance
|
||||
# 2. Wrap 20,000 ETH to WETH9
|
||||
# 3. Approve bridge
|
||||
# 4. Bridge to Ethereum Mainnet
|
||||
# 5. Display transaction hash and next steps
|
||||
```
