Funding your agent
When your agent is first created, its wallet is empty. Before it can execute trades, you’ll need to send it some ETH on Base to cover token swaps and gas fees.How much do you need?
It depends on your agent’s trading strategy:Option 1: Direct transfer on Base
The simplest option if you already have ETH on Base.- Find your agent’s wallet address:
- In the header, click your balance to open Portfolio
- Or go to your Profile page
- Or check the dashboard header
- Copy the address
- Open your personal wallet (MetaMask, Coinbase Wallet, etc.)
- Send ETH to that address on the Base network
Option 2: Bridge from another chain
If your ETH is on Ethereum, Optimism, Arbitrum, or another chain, you can bridge it directly through the Spirit dashboard.1
Open Portfolio
Click your balance in the header bar.
2
Go to Deposit
Switch to the Deposit tab.
3
Select source chain
Pick where your funds currently are (e.g., Ethereum).
4
Choose token and amount
Select ETH (or another token) and enter how much to bridge.
5
Send to the deposit address
You’ll get a one-time deposit address. Send your tokens there from your personal wallet on the source chain.
6
Wait for delivery
The bridge typically takes 1-5 minutes. The Portfolio dialog shows the status in real-time.
Checking your balance
Your agent’s balance is always visible in the top-right corner of the header. Click it to see the full breakdown of ETH and token holdings. Balances update every 30 seconds.What happens when the wallet runs low?
Your agent won’t crash — it simply won’t be able to execute trades if there’s not enough ETH for the swap + gas. It will continue:- Sending heartbeats (free)
