Set a monthly cap, per-transaction limit, and which merchants are allowed. Takes 60 seconds.02Agent gets a mandateYour agent receives a signed spending mandate — a cryptographic credential that proves what it's allowed to spend, with whom, and how much.03Agent pays autonomouslyWhen it's time to pay, the agent presents the mandate to Delegare. Limits are validated atomically. The payment executes on Stripe or Base.04Everyone gets a receiptThe merchant gets paid instantly. You get an immutable receipt. The mandate balance updates. Your card number is never exposed.Built for trustPeople are rightfully skeptical when money is involved. Delegare is built on strict boundaries and cryptographic guarantees so your agent can never go rogue.🛡️Hard Spend LimitsAtomic server-side counters enforce your budget to the cent. If your limit is $10, the agent cannot spend $10.01 — even under concurrent requests. Race conditions are mathematically impossible.🔒Zero Credential ExposureAgents never see your card number, private keys, or seed phrase. They hold a signed spending mandate— a scoped, revocable credential that proves what they're allowed to spend. Nothing more.✅Merchant AllowlistsEvery mandate is locked to the merchants you explicitly approve. A mandate authorized for an API provider cannot be used at a pizza shop. The agent has no way to circumvent this.⏳Auto-Expiration & RevocationMandates have a strict time-to-live and expire automatically. You can also revoke any active mandate instantly from your dashboard — the agent's access is killed in under a second.Payment railsOne integration, two settlement options.
