How a card program runs Bridge for stablecoin cards and wallets and BlindPay for bank funding and local payouts: architecture, flows, and who owns what.
Reading time: about 8 minutes.
Summary: Bridge and BlindPay fit together at different layers of a stablecoin card program. Bridge issues stablecoin-linked Visa cards and runs wallets and card settlement. BlindPay funds those wallets from bank transfers and pays stablecoins out as local currency over Pix, SPEI, ACH, SEPA, and SWIFT (POBO/COBO). The wallet connects them.
Key takeaways
The head-to-head view, rails and custody side by side, is in BlindPay vs. Bridge. This page answers a different question: you already picked Bridge for cards, so how do you wire in bank funding and local payouts without building them yourself? For the wider program decisions, start with how to issue cards with stablecoins.
Bridge handles the card and the stablecoin wallet it spends from. BlindPay handles the bank legs: money in from a bank account and money out to one. Neither has to replace the other.
| Use Bridge for | Use BlindPay for |
|---|---|
| Issuing stablecoin-linked Visa cards through one API | Funding the cardholder wallet from US bank transfers (ACH, wire, SWIFT) through a virtual account in the cardholder's own name |
| Custodial Bridge wallets, or cards that spend from a non-custodial wallet with an onchain approval | Payins over Pix, SPEI, Transfers 3.0, and PSE that deliver USDC or USDT to the wallet |
| Card authorization, capture, refunds, and settlement with Visa | Payouts to local bank accounts over Pix, SPEI, ACH Colombia, Transfers 3.0, ACH, RTP, Domestic Wire, SEPA, and SWIFT (POBO/COBO) |
| Cardholder KYC and the cards endorsement (on the Stripe Issuing path) | KYC and KYB for the customers who hold virtual accounts and send payouts |
| Card statements and cardholder support required by network rules | Payout tracking with UETR and MT103 confirmations on SWIFT |
Bridge's reach keeps growing. Visa reported Bridge-enabled cards live in 18 countries on March 3, 2026. Bridge reported 30 countries through its Stripe Issuing integration on April 29, 2026, with a goal of 100+ by the end of the year. Check the live list for your markets.
Picture five boxes in a row, with the cardholder wallet in the middle. Money enters on the left through BlindPay, sits in the wallet, leaves through the card in the middle, and leaves through BlindPay on the right when it goes to a bank account.
Three design choices follow from this picture.
The wallet is the contract between providers. Per Stripe's docs for Bridge-backed cards, a card can spend from "a Bridge custodial wallet, a Privy non-custodial wallet, or any other non-custodial wallet". If you use a non-custodial wallet, BlindPay can settle virtual account deposits straight into it.
The network has to match. BlindPay settles on Ethereum, Polygon, Base, Arbitrum, Tempo, Arc, Stellar, Solana, and Tron, with USDC or USDT depending on the network. Confirm which network and token your Bridge card spends from, then link that same wallet on the BlindPay side.
Your ledger owns the available balance. The card authorization deadline is short, so your systems decide from a ledger, not from a live chain query. The same ledger tells you how much a cardholder can send to a bank account.
Take a freelancer in Brazil paid by a US client. They spend part of the money on a card and send the rest to their bank account in reais.
virtualAccount.complete webhook fires.payin.complete.Most failures come from timing, not from either API. Plan for these four.
| Risk | What happens | How to prevent it |
|---|---|---|
| Payout drains a pending capture | The cardholder cashes out funds that a card capture still needs | Available to pay out = wallet balance minus open card holds |
| Network mismatch | Deposits arrive on a network the card does not spend from | Link the card's wallet and network on both sides at onboarding |
| KYC timing | The cards endorsement expires before the card is created | Create the card in the same onboarding session |
| Overcapture pull | Bridge pulls more than the purchase at authorization for some merchant categories, then refunds the difference | Hold the larger amount, release on capture |
The overcapture behavior is documented by Stripe: Bridge "might also proactively pull an additional amount at the time of authorization based on the MCC". Treat the pulled amount as the hold, not the purchase amount.
When a BlindPay payout cannot be delivered after the stablecoins are collected, BlindPay refunds them to the quote's refund wallet, or to the sending wallet when none is set. On Pix and other non-USD local rails the refund is automatic. USD payouts, and payouts whose review times out, are refunded after an operator review. Route those refunds back into the same ledger balance.
Yes. The pattern depends on a wallet the card spends from, not on Bridge specifically. Rain and Stripe Issuing with Bridge slot into the same card box. If your card or account layer is BVNK, which Mastercard finished acquiring on August 3, 2026, split by job the same way: the card and account stay there, and the local payout leg runs through BlindPay. The BlindPay vs. BVNK comparison covers that pairing.
BlindPay is an end-to-end stablecoin-to-local-currency payout API, and in this stack it owns both bank legs. Bridge runs the card. BlindPay moves money into and out of the wallet behind it.
Into the wallet: a US virtual account per cardholder, in their own name, converts ACH, wire, and SWIFT deposits to USDC or USDT. In Latin America, payins over Pix, SPEI, Transfers 3.0, and PSE do the same. Out of the wallet: payouts over Pix, SPEI, ACH Colombia, Transfers 3.0, ACH, RTP, Domestic Wire, SEPA, and SWIFT (POBO/COBO), funded at send time with no pre-funding per country.
Fees come from a monthly plan plus per-transaction fees that each quote discloses before you execute. KYC and KYB run in the same API, and every payin and payout fires a signed webhook your ledger can consume.
