Which one, for what

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

A person signs up by email, clicks a verification link and creates a passkey in a browser before any agent can spend

Privy Wallets (server wallets, agent wallets, policy engine) B

Best for Builders who need fine-grained, enclave-enforced spending rules on programmatic wallets, or who want an agent to sign for a person's wallet with a revocable scoped signer.

Verdicts

Kite Agent Passport

Spending sessions with per-transaction and total caps, a lifetime and passkey approval are enforced by the service, with step-up checks and an audit log. A person must sign up by email and create a passkey before an agent can pay. No published fee rate, OpenAPI file or Passport status page was found.

Privy Wallets (server wallets, agent wallets, policy engine)

Default-deny policies with DENY precedence on recipients, values, contracts, calldata, typed data and time windows, enforced in AWS Nitro Enclaves. Database problems took API endpoints down for 71 minutes on 18 September 2026, one of 13 incidents since July.

Before you call either

Kite Agent Passport

  1. Run kpass with --output json --no-interactive and branch on the exit code and error_code. Exit 6 is a session policy breach, so request a new session rather than logging in again
  2. Pass --idempotency-key on every kpass session execute so a retry after a timeout does not pay twice
  3. Ask the person for a session with a small per-transaction cap and a short --ttl, and confirm the merchant URL before executing
  4. Use kpass sandbox test mode and the faucet to try a payment flow without real funds. Scoped cards are not available in sandbox
  5. Check the kite-passport skill's trigger rules before installing it, since it directs the agent to paid services ahead of free tools

Privy Wallets (server wallets, agent wallets, policy engine)

  1. Add a rule for every RPC method the agent needs; a wallet with a policy denies anything unlisted
  2. Pair a rolling cap with a lower per-transaction cap, since aggregations update only after signing
  3. Send an idempotency key on /rpc, /transfer and /wallets calls; reusing one with a changed body returns 400
  4. Set maxValue on the x402 or MPP client for every request
  5. Retry a transaction_broadcast_failure; don't retry a policy_violation
