Overview
- Mastercard is expanding its Crypto Credential framework so users can use human‑readable, verified aliases instead of long wallet addresses.
- Mercuryo conducts identity checks and issues the aliases, which users can link to their own wallets without surrendering private keys.
- An optional non‑transferable credential on Polygon signals verified status onchain and helps applications route credential‑based transfers.
- Polygon was selected for payments‑grade speed, low fees, and throughput, with recent Rio and Heimdall v2 upgrades improving finality and reducing reorg risk.
- Initial functionality prioritizes receiving via alias, with sending capabilities indicated as the next step in the rollout.
