Stablecoin escrow for B2B supply. Paid on delivery, not on invoice.
Pay vendors, sub-contractors and service providers in stablecoins, at home or across borders. Funds lock when the agreement is signed and release milestone by milestone on proof of delivery.
Paying on invoice leaves someone carrying the risk.
Pay upfront and the buyer carries the risk that the work never arrives. Pay after delivery and the supplier carries the risk of a late or missing payment. Net-30 and net-60 terms push that risk onto whoever has less leverage, and cross-border payments add days of settlement on top.
With Portafino, the buyer funds a smart agreement when the deal is signed. The supplier can see the money is committed before starting work. Each milestone releases on its own once delivery is verified, so neither side has to trust the other with the full amount.
Five steps. One agreement.
Agree
Both sides sign the terms: the milestones, the amounts and the evidence each release needs.
Lock
The buyer funds from fiat through a licensed on-ramp partner or from a stablecoin balance. Neither side can withdraw alone.
Deliver
The supplier delivers and attaches proof of delivery to the milestone.
Verify
The buyer confirms the delivery, or the agreed check runs.
Release
That milestone's funds release to the supplier's wallet or bank account.
Wire, letter of credit or smart agreement.
International wire
Quick to send, with no protection once it's sent. The buyer carries the full risk if the supplier doesn't deliver.
Letter of credit
Bank-backed and document-based, but slow and costly to arrange, and built for large single shipments rather than repeat or milestone work.
Smart agreement
Funds committed at signing, released per milestone on verified delivery, with disputes resolved in the same flow.
What suppliers and buyers ask first.
Who holds the funds?
Neither Portafino nor either party alone. Licensed partners handle payments, custody and conversion, and funds release only on verified delivery or a ruling.
Does my supplier need a crypto wallet?
No. Suppliers sign in with a passkey and can be paid to a Portafino wallet or a bank account, without managing a seed phrase or private key.
Which currencies can we use?
Fund from fiat through a licensed on-ramp partner or from an existing stablecoin balance. Settlement uses USDC, USDT, EURC or BILS.
What happens if a delivery is disputed?
The money for that milestone stays locked. Either side can propose a split from 0% to 100%. If they can't agree, AI arbitration decides, and its ruling is final.
Can we pay suppliers in other countries?
Yes. Agreements work at home and across borders. Fiat on- and off-ramp availability varies by jurisdiction.
