A user asks your crypto AI agent, “What would it cost to send these tokens?” A useful answer names the network, gives a fee estimate and says when it was calculated. The user asked for a quote. If a wallet opens a signature request, your agent has already gone further than the task requires.
Start with that distinction when you build on Bluwhale’s crypto AI agent workflows. Give a fee monitor the tools to read network data. If you later add transfer preparation, make the destination, asset and amount visible before the user decides whether to sign. The wallet permissions should reflect the job your user actually chose.
Where confidential computation fits in Bluwhale
Oceanum provides TEE-backed execution and hardware attestation. Bluwhale verifier nodes check those attestations. Your wallet still needs a separate authorization step before signing. See the current node documentation.
Crypto AI agent developer checklist
Run three requests against a test wallet before exposing a signer. Save the proposal, the wallet’s response and the actual tool calls for each run. That gives another developer enough information to reproduce a failure.
- Wrong network: the proposal is blocked or rebuilt for the explicitly selected network before approval.
- Changed recipient: the earlier approval is not reused for a different destination.
- Uncertain submission: the existing transaction is investigated before a second request is created.
These are proposed acceptance tests, not measured results from a particular platform. Extend them with the financial AI agent failure-test guide and record the wallet, tool and policy versions used in your test.
Which wallet permissions does this agent need?
Write down which of these levels the first version needs:
- Observe: read relevant wallet or protocol activity.
- Explain: interpret that activity or describe a proposed action.
- Prepare: assemble a proposal for a separate review and authorization step.
- Execute: request an action through an explicitly authorized signing path.
A gas-cost explanation can be useful at the first two levels. It does not automatically need the ability to sign. Keeping the initial job narrow makes it easier to evaluate whether the agent helps the user.
Isolate signing authority from the model’s reasoning process. Use MetaMask's agentic wallet security guidance to design key isolation, scoped permissions and transaction checks for your wallet.
Write an explicit policy for the chosen job
Suppose the user reviews a proposal for 25 USDC on Ethereum. Bind the approval to the chain, token contract, amount and recipient shown. If a tool later substitutes a different address, discard the approval and show the changed proposal. Enforce that check in the application or wallet before the signer receives it.
A user instruction such as “send it to the usual address” still needs a resolved recipient and an authorized action. If either is unclear, the useful response is to collect the missing information before preparing a transaction.
Validate the context before presenting a transaction
Check network and asset identity
Use the relevant network identifier and asset or contract address when interpreting a token. A familiar symbol is not enough to identify an asset across networks. Verify decimals and units before turning a human amount into transaction data. Show the network and asset clearly in the review experience.
Build a case where two assets share a symbol but have different addresses. The workflow should preserve the selected asset's identity throughout the proposal. This is a straightforward test of data handling rather than a test of how convincing the agent's explanation sounds.
Separate reading, messages, approvals and transactions
Reading a public address, signing a message and granting a token allowance are different operations. A request presented as a routine connection should not obscure a broader authorization. Inspect the exact operation and explain its consequence in the review step.
If a workflow involves a token approval, identify the spender, amount and intended purpose. The appropriate limit depends on the application. Make any continuing authority understandable and provide a route to review or revoke it where the relevant wallet and network support that process.
Keep external content separate from instructions
Token metadata, websites and tool responses can contain text that looks like an instruction. Treat that content as input to inspect, not permission to change the agent's job. Test a response that asks the agent to send data elsewhere or switch a recipient. The policy boundary should hold independently of the generated explanation.
OWASP's agentic security framework is a reference for structuring a wider review. Your implementation tests should remain tied to the tools and permissions the agent actually has.
Test the transaction lifecycle, including uncertainty
Consider an illustrative workflow in which a user wants to review a transfer before deciding whether to sign. The agent's output should move through identifiable states:
- Context collected: source account, network, asset and intended recipient are resolved.
- Proposal prepared: amount, destination and relevant cost estimate are visible.
- Checks completed: applicable policy checks and available simulation results are evaluated.
- Authorization requested: the user sees the specific action being approved.
- Submission tracked: a transaction reference connects the request to its observed state.
- Outcome reported: the interface distinguishes pending, confirmed, failed and uncertain outcomes.
Simulation can help explain a proposed transaction under the state it evaluates. It cannot guarantee the eventual outcome as network state and transaction ordering change. If important proposal details change, refresh the review before requesting authorization.
Five failures to reproduce before release
- The selected wallet is on a different network from the proposal.
- A tool returns an old balance or an unavailable gas estimate.
- The user rejects the signature request.
- A submission times out but the transaction may already exist.
- A previously authorized session expires before the next action.
Pay particular attention to the timeout. The wallet may have broadcast the transaction before the response was lost. Use the original transaction reference and the network record to establish its status. While that status is unknown, show “Checking submission” and prevent a second send. If the user rejected the signature, the correct outcome is different: no broadcast and no automatic retry.
Connect the workflow to Bluwhale's agent ecosystem
Bluwhale's developer experience showcases specialized roles including token analysis, security monitoring and gas optimization. These roles provide useful starting points for choosing a bounded task. Explore the developer platform to match your task with current data access and integration options.
For a Bluwhale gas-cost agent, start the release test with a single question: “What would this transfer cost on the selected network?” Save the estimate with its source and timestamp. In a separate test, ask the agent to make the transfer while signing is disabled. The estimate should still work, and the signer should receive zero calls. Those two outcomes show what the read-only version can safely offer users.
Continue to the Agent Store overview when preparing the experience for discovery. For a complementary user perspective, Bluwhale's article on reviewing a suspicious approval before signing explains why the approval moment deserves a clear interface.
Match the task with Bluwhale’s financial data layer before planning an integration. For a user-facing starting point, explore crypto AI agent workflows; use the Agent Store when the next step is discovery or distribution. These pages describe different parts of the same Bluwhale journey.
A three-step wallet permission test
Give a test agent a public address and a reporting task. Use a mock signer with a call counter and no private key. Run the same request under three policies.
- Read only. Return the observed balance and its block. Expected signer calls: 0.
- Simulation allowed. Return the unsigned proposal and simulated outcome. Expected broadcasts: 0.
- Transfer requested with signing disabled. Return a scope error. Both the signer count and broadcast count must stay at 0. A success message or a transaction hash fails this case.
Common questions
Can a crypto AI agent work without a private key?
Yes. Analysis and monitoring can use appropriate read access. Preparing a proposal also does not require giving a model direct access to a private key; authorization can remain in a separate wallet flow.
Is a simulated transaction guaranteed to succeed?
No. Treat simulation as information about the evaluated state. Conditions may change before execution, so keep its timing and assumptions visible.
Can an on-chain action simply be rolled back?
Do not assume that. Recovery depends on the action, protocol and transaction state. Design confirmation, limits and incident response before granting consequential authority.
