The problem

Payment risk is holding business back

In today's global digital economy, payment friction creates uncertainty for both sides of a deal.

Disconnected workflows

Scattered systems create confusion and delays.

Manual dispute processes

Costly, slow resolutions damage trust and relationships.

No audit trail

Lack of verifiable history complicates compliance.

Payment exposure

Upfront payments leave buyers financially vulnerable.

Our solution

Portafino: trustless smart escrow

Portafino is a self-custody blockchain smart contract escrow that replaces uncertainty with automation. Funds are locked upfront and released only when both parties agree that deliverables are met.

  • Funds are secured in escrow, visible to both parties
  • Payments follow mutually agreed milestones
  • Terms only change via mutual agreement or mediator
  • All users are KYC-verified to reduce fraud
  • Transactions are recorded immutably on blockchain
