Soulbound tokens are non-transferable NFTs that stay with the recipient forever. They cannot be sold, traded, or transferred to another wallet, making them perfect for credentials.
Use our verification tool to enter a wallet address or token ID. The system will check the blockchain and display the credential's validity status.
Expired credentials remain on the blockchain but are marked as expired. The credential cannot be used for verification purposes after expiration.
Currently, credentials cannot be revoked once issued. This ensures the integrity and permanence of the credential system.
