From Chatbots to Economic Agents: Autonomous Treasury Management on Base

Sebagian besar implementasi "AI Agent" yang beredar hari ini hanyalah wrapper API over-engineered: sebuah skrip Python memanggil OpenAI function-calling, lalu mencetak JSON ke konsol. Di ujung hari, bot tersebut tetap lumpuh secara finansial. Mereka tidak memiliki neraca, tidak bisa menandatangani state transition di ledger, dan tidak bisa bangkrut jika kalkulasinya salah.

Perubahan mendasar terjadi ketika kita memberikan private key dan autonomous signing rights kepada sebuah model. Bukan simulasi, melainkan eksekusi deterministik di atas Base L2 (Chain ID 8453).

Berikut arsitektur produksi nyata yang memisahkan inferensi probabilistik dari eksekusi on-chain yang deterministik.

Mengapa Base L2 (8453)?

Di Ethereum L1, latensi 12 detik dan gas fee $15 untuk transaksi swap mematikan loop otomasi frekuensi menengah. Rebalancing kas senilai $2.000 dengan gas fee $15 adalah tindakan bunuh diri matematika (0,75% drag per rebalance).

Base memangkas gas fee ke fraksi sen (sub-$0.01 paska-EIP-4844) dengan blok 2 detik. Ini memungkinkan agen kas menjalankan drift rebalancing setiap 10 menit tanpa mengikis principal modal.

Agen ini memiliki alamat kas on-chain operasional:
0x92Aff59709b03b9373b8fA887D24953D60fAd919

Tugasnya sederhana: menjaga eksposur portofolio tetap pada rasio 70% USDbC/USDC dan 30% WETH. Jika volatilitas pasar menggeser rasio di luar deviasi 5%, agen harus melakukan rebalance tanpa campur tangan manusia.

Arsitektur: Decoupling Reasoning dari Signing

Jangan pernah biarkan LLM merakit raw transaction hex. LLM menghasilkan intent, sistem deterministik memvalidasi batas risiko (guardrails), dan engine Web3 menandatangani transaksi.

Jika LLM mengalami halusinasi dan ingin menukar seluruh kas ke memecoin random, modul risk-checking lokal akan langsung menolak sebelum transaksi sampai ke mempool.

+---------------+     Intent JSON     +-------------------+     Signed Tx     +-------------+
| LLM Inference | ------------------> | Deterministic     | ----------------> | Base Node   |
| Engine        |                     | Guardrail Engine  |                   | (RPC 8453)  |
+---------------+                     +-------------------+                   +-------------+
                                                |
                                        [Revert if slippage > 0.5%]
                                        [Revert if target != Whitelist]

Implementasi Runtime

Berikut loop eksekusi Python minimal menggunakan web3.py yang dijalankan di runtime agen:

python
import os
import json
from decimal import Decimal
from web3 import Web3
from web3.middleware import ExtraDataToPOAMiddleware

RPC_URL = os.getenv("BASE_RPC_URL", "https://mainnet.base.org")
w3 = Web3(Web3.HTTPProvider(RPC_URL))
w3.middleware_onion.inject(ExtraDataToPOAMiddleware, layer=0)

TREASURY_ADDRESS = w3.to_checksum_address("0x92Aff59709b03b9373b8fA887D24953D60fAd919")
AGENT_KEY = os.getenv("AGENT_PRIVATE_KEY")

# Uniswap V3 SwapRouter02 di Base
ROUTER_ADDRESS = w3.to_checksum_address("0x2626664c2603336E57B271c5C0b26F421741e481")
WETH = w3.to_checksum_address("0x4200000000000000000000000000000000000006")
USDC = w3.to_checksum_address("0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913")

def execute_rebalance(token_in: str, token_out: str, amount_in_wei: int, min_out_wei: int):
    # Hard Guardrail: Validasi slippage maksimal 0.5%
    assert amount_in_wei > 0, "Invalid amount"
    assert token_in in [WETH, USDC] and token_out in [WETH, USDC], "Asset untrusted"

    router_abi = json.loads('[{"inputs":[{"components":[{"internalType":"address","name":"tokenIn","type":"address"},{"internalType":"address","name":"tokenOut","type":"address"},{"internalType":"uint24","name":"fee","type":"uint24"},{"internalType":"address","name":"recipient","type":"address"},{"internalType":"uint256","name":"amountIn","type":"uint256"},{"internalType":"uint256","name":"amountOutMinimum","type":"uint256"},{"internalType":"uint160","name":"sqrtPriceLimitX96","type":"uint160"}],"internalType":"struct IV3SwapRouter.ExactInputSingleParams","name":"params","type":"tuple"}],"name":"exactInputSingle","outputs":[{"internalType":"uint256","name":"amountOut","type":"uint256"}],"stateMutability":"payable","type":"function"}]')
    router = w3.eth.contract(address=ROUTER_ADDRESS, abi=router_abi)

    params = (
        token_in,
        token_out,
        500,  # 0.05% tier
        TREASURY_ADDRESS,
        amount_in_wei,
        min_out_wei,
        0
    )

    nonce = w3.eth.get_transaction_count(TREASURY_ADDRESS)
    tx = router.functions.exactInputSingle(params).build_transaction({
        'chainId': 8453,
        'from': TREASURY_ADDRESS,
        'gas': 220000,
        'maxFeePerGas': w3.to_wei(0.1, 'gwei'),
        'maxPriorityFeePerGas': w3.to_wei(0.001, 'gwei'),
