Resources · STAXX
Set up STAXX for your Base wallet.
Connect your Base Account, install the AIERC plug-in, then request a transaction review before sending Base Sepolia ETH. STAXX connects your wallet to the plug-in; AIERC provides the review.
Testnet only. This page uses Base Sepolia, a test network. Use test ETH for setup and transfers. Connect a Coinbase Base Account to use this setup. Adding a MetaMask account is optional. If you choose that option, the authorization step grants the selected MetaMask account full control of your Base Account.
Set up your wallet
Your Base Account does it all itself.
It signs the installation, sends it, and claims the NFT. AIERC reviews the installation, NFT claim and transfers submitted through this page before requesting a signature. The installation is the one step your account pays its own small network fee for (test ETH on Base Sepolia); the NFT claim and later sends have the fee sponsored through STAXX. Steps 2 and 3 are optional — only for people who also want a MetaMask key on their Base Account.
- 01Connect your Base Account
Open Coinbase Wallet and sign in to the account you want to use. If you need a new account, complete Coinbase’s signup first. When you return, your wallet address and test ETH balance appear here.
- 02Optional: choose a MetaMask account
Connect an account you control. MetaMask will ask to use Base Sepolia if it is on another network. This account needs test ETH if you use it to fund your Base Account or later remove its own access.
Connecting shows the address you selected. The next step asks separately for permission to control your Base Account.
- 03Optional: authorize that MetaMask account to control your Base Account
Your Base Account needs test ETH to pay for this authorization. If its balance is empty, transfer 0.002 Base Sepolia ETH from the MetaMask account above. MetaMask also needs enough test ETH to pay the transfer fee.
Full account control. Approving this adds your MetaMask address as another owner of your Base Account. It can independently move assets and add or remove other owners, including your existing passkey owner. Your passkey is retained when this address is added. No seed phrase or private key is imported into MetaMask.
This authority continues after installation. You can remove this MetaMask account’s access using the control below, provided you retain another way to access your Base Account. Review the selected addresses before approving in Coinbase Wallet.

- 04Install the AIERC plug-in
AIERC reviews the installation first. Coinbase Wallet then asks you to sign the installation request and to approve the transaction that records it. Your Base Account pays the installation network fee, so it needs some Base Sepolia test ETH. Sponsorship becomes available after the plug-in is installed. After this step, the NFT claim and later sends are sponsored through STAXX. The separate account-control permission in step 3 still applies.
- 05Receive your STAXX NFT
Once installation is recorded, you can claim the STAXX NFT into your Base Account. It represents your wallet’s STAXX plug-in installation. Your Base Account submits the claim; STAXX asks for the fee to be sponsored. Receiving the NFT is separate from installing the plug-in and does not show that a particular transfer has been reviewed.
Review and send test ETH
Enter a recipient’s wallet address and the amount of Base Sepolia ETH to send. Select Review transfer to see AIERC’s assessment of those details. The review does not transfer funds.
Select Send through STAXX and AIERC reviews the exact transfer first. If it is CLEAN, Coinbase Wallet opens with the network fee sponsored. If it is FLAGGED, the findings are shown and the sponsored send does not go ahead; you can still choose to send it yourself, unsponsored. A review is valid for ten minutes and only for that exact recipient, amount and data.
Your Base Account supplies the amount being sent. Sponsorship, when provided, covers the network fee. This page does not configure reviews for transfers made elsewhere.
Buy through STAXX
A test transfer proves the path. A purchase uses it. Select Use my Base Account on the terminal: this site then treats your Base Account as your connected wallet, and every payment you make on the terminal goes out through STAXX — the same sponsorship request, the same AIERC review before the network fee is covered, the same record on the Chaingentic activity report. MetaMask is not opened on this path.
The terminal opens on Base Sepolia. Pick something priced in test dollars, press Buy, and confirm in Coinbase Wallet.
Manage MetaMask access
Remove the connected MetaMask address from this Base Account’s owners. This revokes that address’s owner authority; it does not uninstall AIERC, remove the STAXX NFT, or revoke separate permissions granted elsewhere.
You must retain access through another owner, such as your Coinbase passkey. This page checks that another owner exists, but cannot check whether you can use that owner’s credentials. MetaMask approves its own removal and pays the testnet network fee. Removing its authority may prevent it from managing this installation afterward.
Connect your Base Account and MetaMask above, then check access.
Network and records
Transfers submitted here use Base Sepolia. The Chaingentic activity report is a separate record of AIERC intelligence activity. Check the subject transaction in a report before treating it as the record for your transfer.
