# Implementation Complete Summary
|
||||
|
||||
**Date**: 2025-01-12
|
||||
**Status**: ✅ All Recommendations Implemented
|

|
||||
## ✅ Yes, Etherscan Gas API Assists!
|
||||
|
||||
The Etherscan Gas API has been integrated and provides significant benefits:
|
||||
|
||||
### Benefits
|
||||
1. **Real-Time Gas Prices**: Get current network gas prices
|
||||
2. **Multiple Speed Options**: Safe, Proposed, Fast
|
||||
3. **Prevents Stuck Transactions**: Use appropriate gas for network conditions
|
||||
4. **Multi-Chain Support**: Works with Ethereum, BSC, Polygon, etc.
|
||||
5. **Automatic Fallback**: Falls back to RPC if API unavailable
|
||||
|
||||
### Implementation
|
||||
- ✅ Created `get-optimal-gas-from-api.sh`
|
||||
- ✅ Integrated into all key scripts
|
||||
- ✅ Automatic fallback to RPC gas price
|
||||
- ✅ Multiplier-based pricing (1.5x for normal, 2x for replacements)
|
||||

## Usage
|
||||
|
||||
### Get Optimal Gas Price
|
||||
```bash
|
||||
# Proposed speed (recommended)
|
||||
./scripts/get-optimal-gas-from-api.sh proposed
|
||||
|
||||
# Fast speed (for urgent transactions)
|
||||
./scripts/get-optimal-gas-from-api.sh fast
|
||||
|
||||
# Safe speed (for non-urgent transactions)
|
||||
./scripts/get-optimal-gas-from-api.sh safe
|
||||
```
|
||||
|
||||
### Send Transaction with Optimal Gas
|
||||
```bash
|
||||
./scripts/send-with-optimal-gas.sh \
|
||||
"$CONTRACT" \
|
||||
"functionName(uint64,address)" \
|
||||
"$ARG1" \
|
||||
"$ARG2"
|
||||
```
|
||||
|
||||
### Monitor Transaction
|
||||
```bash
|
||||
./scripts/monitor-transactions.sh 0x... 300
|
||||
```
|
||||
|
||||
### Monitor Fees
|
||||
```bash
|
||||
./scripts/monitor-fees.sh 1.0
|
||||
```
|
||||
|
||||
### Retry Failed Transaction
|
||||
```bash
|
||||
./scripts/retry-with-backoff.sh \
|
||||
"cast send ... --gas-price \$GAS_PRICE" \
|
||||
3 \
|
||||
5
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Remaining Manual Actions
|
||||
|
||||
### 1. Deploy/Verify LINK Token
|
||||
- **Status**: LINK token contract appears empty
|
||||
- **Action**: Deploy LINK token or verify existing
|
||||
- **Impact**: Required for CCIP fee payments
|
||||
|
||||
### 2. Fund Bridge Contracts
|
||||
- **Status**: LINK balances unknown
|
||||
- **Action**: Transfer LINK to bridge contracts
|
||||
- **Amount**: Minimum 10 LINK per bridge (recommended)
|
||||
|
||||
### 3. Resolve Stuck Transaction
|
||||
- **Status**: Nonce 37 stuck
|
||||
- **Action**: Wait or use extremely high gas
|
||||
- **Script**: `configure-ethereum-mainnet-destination.sh` now uses 2x fast gas
