# flashbots
## Python implementation
Dependencies:
- [Web3.py Flashbots](https://github.com/flashbots/web3-flashbots)
Submit bundle transactions to flashbots relayer
```zsh
cd python
python simple_flashbot.py
```
Example of transactions:
```python
nonce = w3.eth.get_transaction_count(sender.address)
tx1: TxParams = {
"to": fallback_mainnet,
"value": 0,
"gas": 42000,
"data": "0x",
"maxFeePerGas": Web3.toWei(50, "gwei"),
"maxPriorityFeePerGas": Web3.toWei(2, "gwei"),
"nonce": nonce,
"chainId": CHAIN_ID,
"type": 2,
}
tx1_signed = sender.sign_transaction(tx1)
tx2: TxParams = {
"to": receiverAddress,
"value": Web3.toWei(0.0005, "ether"),
"gas": 21000,
"maxFeePerGas": Web3.toWei(200, "gwei"),
"maxPriorityFeePerGas": Web3.toWei(50, "gwei"),
"nonce": nonce + 1,
"chainId": CHAIN_ID,
"type": 2,
}
bundle = [
{"signed_transaction": tx1_signed.rawTransaction},
{"signer": sender, "transaction": tx2},
]
```
## Typescript
Dependencies:
- Flasbots Bundle Provider `@flashbots/ethers-provider-bundle`
```zsh
cd src
ts-node index.ts
```
