Mercuryo, Polygon Labs and Mastercard are collaborating to expand Mastercard Crypto Credential to include self-custody wallets.
The solution provides simple aliases to replace complex blockchain addresses, aiming to improve inclusivity, security and scalability while supporting trust and standardised verification for users.
Polygon Labs will provide the blockchain infrastructure as the first native network to support the solution, while Mercuryo will handle user onboarding.
Mastercard’s verification framework underpins the programme, enabling alias-based crypto transfers with faster, lower-cost transactions suitable for digital payments and asset transfers.
Mercuryo will onboard users and provide them with an alias after completing know-your-customer (KYC) verification.
Once verified, users can link their wallets to their Mastercard Crypto Credential username and may request a Soul Bound Token on the Polygon blockchain.
This token signals on-chain that the wallet supports transaction processing, including Travel Rule compliance and verification checks to confirm ownership by a verified user.
Users will then be able to receive crypto using their alias and send it in the future, simplifying transfers while maintaining self-custody.

“By streamlining wallet addresses and adding meaningful verification, Mastercard Crypto Credential is building trust in digital token transfers,”
said Raj Dhamodharan, Executive Vice President, Blockchain & Digital Assets at Mastercard.
“Bringing Mercuryo and Polygon’s specialised expertise together with our infrastructure is making digital assets more accessible and reinforces Mastercard’s commitment to driving secure, intuitive, and scalable blockchain experiences for millions of users globally.”
Petr Kozyakov, Co-Founder and CEO of Mercuryo, said,

“This collaboration will further the path to mass adoption, providing a simplified and streamlined means of sending and receiving digital tokens while users maintain self-custody of their digital assets.”
