01 / Integration & customization

Start with a task that has a defined cost

Identify the provider, payment asset, budget and stop conditions, then assess account and chain compatibility. The implemented permission and execution components provide the starting point; LLM decisions and real providers still require integration.

02 / Integration & customization

Fit permission management to your business

Build on policy review, grants, payments and revocation. Policy creation, organization identity, cost centers, paid plans and real wallet compatibility are separately scoped work.

WHAT WE CAN BUILD WITH YOU

Your market. Your version.

These are customization directions. We agree what to retain, adapt and add before preparing an implementation proposal and quote.

01

A paid-data research assistant

Connect a provider, map queries to payment tasks and tailor limits, result delivery and cost reporting.

02

An enterprise automation platform

Add team or task budgets, approvals, organization sign-in, roles and cost centers for internal workflows.

03

An Agent permission center in a wallet

Integrate authorization lists, payment history, expiry reminders and revocation. Scope network and account compatibility separately.

BUILT BEHIND THE EXPERIENCE

See how the workflow is built.

01

Independent signing and smart accounts

A Node runner signs operations that pass through the API, Alto Bundler and EntryPoint into smart-account execution.

02

Guard verification

Guard validates authorization. The local demo also rejects an operation signed before revocation but submitted afterward.

03

State recovery

Separate chain confirmation from API registration. Retry synchronization without repeating a successful authorization transaction.

What I’m building here

My development focus connects Owner authorization, an independent Node signer and smart-account execution, including revocation and recovery after synchronization failures.

  • Independent signing and smart accounts
  • Guard verification
  • State recovery

Can an old signature still execute after revocation?

The local demo submits a previously signed operation directly to the bundler after revocation; it is rejected on-chain. This differs from an API preparation limit check, so the page explains each verification layer separately.

What comes next

The permission-focused Owner workspace is implemented. Real providers, LLM decisions and full policy creation require separately scoped integration.

Questions before we talk

Must the Owner approve every payment?

After authorization, the Agent signs in its own runtime. The Owner does not need to sign each payment.

Does the Owner need the Agent private key?

No. Authorization uses the Agent public address; its private key stays in its execution environment.
