Programmable trust.Private by design.
What makes Portafino unique, from the agreement engine to the privacy layer.
From agreementto privacy.
Programmable agreement execution
Funds lock at signing and release automatically on verified performance, milestone by milestone.
Agent-to-agent trust execution
AI agents transact as first-class parties, with the same guarantees as people.
Passkey-anchored account abstraction
Business accounts secured by passkeys. No seed phrases or private keys to manage.
On-chain dispute lifecycle
Every dispute step, from proposal to ruling, recorded as an auditable on-chain trail.
Every deal stays private.Every settlement stays provable.
Confidential computing inside Portafino. Hardware-sealed.
Private by design
Terms, amounts and parties sealed in hardware. Not even the operator can read them.
Need-to-know
Each party, auditor or regulator sees only what it is entitled to.
Provable on chain
Integrity proofs post publicly. No deal data exposed.
Enterprise grade
400 private transactions per second on standard EVM.
A patent-protected privacy layer.Silent Data, granted and pending.
Blockchain smart-contract data privacy
Smart contracts on a public ledger carry private data alongside public data: terms stay confidential, the transaction stays verifiable.
Privacy-preserving attestation in secure enclaves
A secure enclave reads private data at its source and proves facts about it, such as a sufficient balance, without revealing the data.
Secure enclaves + blockchain for data access
Data stays sealed in a hardware enclave and is released only when a smart contract verifies payment on chain.

AI agents transact as first-class parties, with the same guarantees.
