CUSTOM BUILD

Fixed-price wallet, onramp, Connect and agent payment builds. Pay online, start fast.

Each build below has a published price and pays securely on this page through Stripe. Payment is recorded from Stripe's signed confirmation, never from the page you return to, and SET then contacts you to confirm scope, access, and scheduling. Every purchase is for a US business, under the Terms of Service.

Paid contractors or bounty winners in stablecoins during 2026? The USDC Payouts 1099 Pack has its own page: a payout ledger verified on chain for your 1099s, from $750.

Building a deposit project? You pay 50% to start and the balance at launch. Readiness and scoping fees are credited toward the build that follows.

Changed your mind? Cancel any purchase on this page within 7 days after you pay for a full refund (Terms §3.7).

WALLETS AND CRYPTO ONRAMP

Embedded Wallet + Onramp

Give your users a wallet at sign-in, let them fund it by card, and let them cash out to a bank account. SET builds on an embedded-wallet provider for login and wallets, on Stripe's crypto onramp for funding, and on a licensed payments provider for cash-out. Your business must be approved by Stripe for onramp access and needs its own developer account with the cash-out provider, which the Readiness Check names; SET never approves, holds, exchanges, or delivers crypto.
