Mesh Link Tokens

Link Tokens enable crypto-to-fiat transfers through the Levl platform by integrating with Mesh Connect. A link token authenticates and authorizes a user session, allowing them to securely transfer cryptocurrency from their connected exchange or wallet to fiat currency for the intended beneficiary.

Overview

The Link Token flow allows your users to:

Connect their cryptocurrency exchange or wallet account
Authorize a transfer of cryptocurrency
Have the crypto converted to fiat and delivered to the beneficiary

This integration leverages Mesh Connect's infrastructure to provide a seamless user experience while maintaining security and compliance.
