Steps
Set up a Bridge (Stripe) account and configure supported stablecoins for inbound settlement — Bridge supports USDC, USDT, EURC, PYUSD, and its own USDB across multiple chains including Ethereum, Solana, Polygon, Arbitrum, Base, Tron, and Stellar.
Use Bridge's conversion API to convert an incoming stablecoin balance into your target fiat currency rather than manually bridging on-chain funds to a bank account yourself.
Use the payout API to disburse the converted fiat via the applicable rail (ACH, SEPA, or SWIFT depending on recipient region) to your sellers' or contractors' bank accounts.
Reconcile each stablecoin receipt to its corresponding fiat payout by matching Bridge's transaction/reference IDs against your internal ledger, since conversion and payout can occur as separate steps.
Handle on-chain confirmation delays (block finality) before treating a stablecoin deposit as settled and available for conversion, rather than triggering payout immediately on mempool detection.
If you need redundancy or broader regional fiat coverage, evaluate pairing Bridge with a second orchestration/off-ramp provider rather than depending on a single rail for every payout geography.
Known gotchas
On-chain settlement finality varies by network — treating a transaction as final before adequate confirmations exposes you to reorg risk on faster chains.
Fiat off-ramp coverage differs by region (ACH/SEPA/SWIFT support varies by currency and country), so don't assume every payout corridor is available without checking current coverage for that specific country.
Since Bridge now operates inside Stripe's stack after the acquisition, verify current product boundaries (e.g., interplay with Stripe Treasury/Issuing) before assuming feature parity with its pre-acquisition standalone API.
