## On-Chain Identity Attestation

On-Chain Identity Attestation involves recording the fact that a user has been verified by a trusted third party directly onto the blockchain. This "attestation" serves as a digital badge that other protocols can query to grant the user access to restricted services, such as leveraged derivative pools.

Once an identity is verified once, the user does not need to undergo repetitive KYC processes for every new protocol they join. This increases efficiency and user experience across the DeFi ecosystem.

These attestations are typically stored as non-transferable tokens or specific metadata associated with a user's wallet address.
