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.
Your Base Account does all of this itself: it signs the installation, sends it, and claims the NFT. AIERC reviews each step before your wallet opens. 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.
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.
Connect an account you control. MetaMask will ask to use Base Sepolia if it is on another network. This account needs test ETH to pay the network fees for installation and the NFT claim.
Connecting shows the address you selected. The next step asks separately for permission 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.
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.
Some Base Accounts have been reported to reject Base Sepolia transactions. If Coinbase Wallet says the network is unsupported, this setup cannot finish through that account. See the reported compatibility issue for details. Keep this test on Base Sepolia.
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 this one network fee itself — a plug-in cannot have its fee sponsored before it exists — so the account needs a little Base Sepolia test ETH. After this step, the NFT claim and later sends are sponsored through STAXX. The separate account-control permission in step 3 still applies.
Receive your STAXX NFTOnce 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.
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.
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 nothing is sent unless you 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.
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.
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.
