Commerce

# Trusted buyers. Verified sellers. Disputable evidence.

Marketplaces stop rebuilding identity and reputation from scratch. Buyer and seller identity become portable. Every step of a transaction becomes signed evidence.

[See the platform](https://www.iden2.com/platform/phenix)

In practice

## How is trust established between a buyer and a seller?

Industry problem

## Every marketplace rebuilds identity and reputation from zero.

Fraud is caught after settlement. Seller reputation does not travel. Disputes come down to screenshots. Age-gated purchases lean on self-attestation.

* 1–2% of GMV is lost to fraud and chargebacks on typical marketplaces.
* Seller reputation is captive to a single platform.
* Age-gated commerce fails audits routinely.

iDen2 solution

## Portable trust for both sides of the transaction.

Buyers present verified age, address, or payment credentials with selective disclosure. Sellers present verified business credentials. Every order, shipment, and delivery is signed evidence.

* Age and address verification with no PII exposure.
* Portable seller reputation, backed by verifiable credentials.
* Signed order lifecycle events for dispute resolution.
* Agent-driven commerce with signed buyer mandates.
