FAQ: Privy wallets, Bridge cash-out and SET's payment services.

SET Wallet & Cash-Out for individuals: a permanent SET Cash-Out Address that pays your own US bank whenever you send USDC to it, for 3% per cash-out or 1.5% on Pro at $29 a month, in a Privy wallet only you control with your own US account number from Bridge, free to open with a 3% fee on each bank deposit. For platforms that pay in USDC: SET Direct Deposit, which gives their US payees dollars and the platform a share of SET's fee. For businesses: SET Payouts, which pays an overseas team in USDC on Base from one list, free for up to 5 people a month, Starter $29 a month for 25 and Growth $99 a month for 100; and three core services: SET Connect, embedded payments billed under your own business name on SET's Stripe Connect platform, from $149 per month plus 1% of each payment; an SEO, AIO and GEO visibility review at $99 per hour, capped at 5 hours; and a six-month custom payment retainer at $462 up front plus a $750 build fee on delivery, with platform fees on your customers' payments. SET also sells fixed-price builds, bought online on its Custom Build page, and a $49 Embedded Checkout Starter Kit for teams that build it themselves.

It is how SET Wallet & Cash-Out works. Privy creates self-custodial wallets when you sign in with your email, so only you can approve a send. Bridge, a Stripe company, issues US account and routing numbers in your name, converts each bank deposit to USDC, USDT or PYUSD for your wallet, and pays USDC on Base back out to your US bank by ACH. SET charges 3% on each deposit and cash-out; opening a wallet is free.

SET Wallet cashes out through your SET Cash-Out Address, whether the USDC comes from whoever pays you or from your own wallet: 3% per cash-out, $3.00 on 100 USDC, or 1.5% on Pro at $29 a month, $1.50 on 100 USDC. Bridge withholds SET's fee, and Bridge's own fee and any network fee appear on Bridge's receipt.

Yours. Your business is the merchant of record, its name appears on the payment and the card statement, and each payment settles to your own Stripe account.

No. Payments settle directly to your Stripe account. SET builds and operates everything around the payment, including onboarding, checkout, webhooks, reconciliation, and monitoring, but never holds the funds.

Standard is $149 per month plus 1% of each payment. Growth is $299 per month plus 1%, for subscriptions, several products, and invoicing. Custom starts at $499 per month plus 1% and is quoted at scoping. The fee is fixed in a written agreement before anything is charged, and Stripe's own processing fees are separate. If you refund a customer, SET returns its 1% on the refunded amount.

Up front, at $99 per hour for the number of hours you choose, from 1 to 5, so a review costs $99 to $495. Work stops at the hours you paid for unless you approve more in writing, and the report itemizes the hours used.

No. The retainer is a direct payment to SET for SET's work. Only your customers' payments inside the solution SET builds run through the Connect platform to your own Stripe account.

$462 paid up front when the agreement is signed, which is $77 per month for six months, plus a $750 build fee due when SET delivers the build. Your customers' payments during the term also carry the Embedded Payments Platform fee for your tier, from $149 per month plus 1% of each payment.

No. Stripe-controlled components collect payment information. SET creates the applicable provider session and presents the secure component within the customer experience.

A mobile webview is not the same as native SDK development. Native Android or iOS work is included only when SET confirms the customer's supported framework and required provider access in writing; otherwise native work requires a separate quote.

Only after a written agreement and authenticated payment evidence. Provider review time, such as Stripe's verification of your business, and customer-caused delays are excluded from any estimate.

Open Payment is only for a scope, invoice, or payment purpose already confirmed by SET in writing. Entering an amount does not create a new implementation scope or authorize fulfillment.

Two machine-readable checks that an AI agent can buy one request at a time, with no account. The Agent Payment Readiness Assessment (POST /api/agent/readiness) takes what you declare about ten parts of a payment workflow, from discovery and the HTTP 402 challenge to webhooks, fulfillment and recovery, and returns a JSON report of the blocking controls and the order to fix them; it verifies nothing independently. The AI Visibility Check (POST /api/agent/ai-visibility) fetches one public page and returns a 0 to 100 score against a published rubric, which of 15 search and AI crawlers its robots.txt allows, the page's indexing, snippet, title, canonical and JSON-LD signals, and prioritized findings with the fix for each; a page that cannot be checked is not charged. Both are also tools on SET's MCP server at /api/mcp. Neither result authorizes a payment or promises any ranking or citation.

Each paid endpoint answers an unpaid request with HTTP 402 Payment Required. Under the Machine Payments Protocol (MPP) the agent pays $1.00 by card or Link through a Stripe Shared Payment Token; under x402 it pays 1 USDC on Base, settled through Coinbase's facilitator to SET's Stripe account. The agent retries with the payment credential and receives the result with a receipt. An agent that calls often can prepay with SET Agent Credits instead: 25 calls for $20 or 100 calls for $70, each lasting 12 months, or 50 calls a month for $29, spent by sending its key as a Bearer token. An Idempotency-Key header makes a retry return the paid result without a second charge, and every payment is reconciled from Stripe's signed webhook.

They are fixed-price builds on SET's Custom Build page for a business that wants to sell to AI agents itself. The $497 Agent-Payment Readiness Audit is a written review, delivered within 10 business days after SET has access, of your discovery, 402 challenge and receipt, idempotency, webhook verification, fulfillment ledger, and refunds and disputes, with a prioritized fix list. The $1,500 MPP Endpoint Install puts one paid HTTP 402 endpoint that accepts card and Link into your own stack on your own Stripe account; the $2,500 MPP + x402 Endpoint Install adds USDC on Base, paid to your own wallet or Stripe deposit address. Each install is handed off within 20 business days after access and submitted to the mpp.dev and MPPScan directories. SET never holds your funds or keys, and Stripe, the x402 facilitator and the directory operators make their own decisions. Teams that build it themselves can buy the $79 MCP Monetization Kit.
