 ## API Routes
 
 - `/api/fetchPoaps`: Fetches POAPs for a given Ethereum address or ENS name
 
+## Smart Contracts
+
+`POAPVerification.sol`: Integrates with the POAP protocol for verifying real-life event attendance.
+
+`AttestationService.sol`: This contract implements on-chain attestation using the Ethereum Attestation Service (EAS). It features role-based access control, with specific roles for attestation creators and administrators. The contract uses a custom schema for mission enrollment attestations, which includes the user's address, token ID, timestamp, and attester's address.
+
 ## Smart Contract Functions
 
-The app utilizes the following smart contracts:
+1. `createMissionEnrollmentSchema()`: Creates the schema for mission enrollment attestations
+2. `createMissionEnrollmentAttestation(address recipient, uint256 tokenId)`: Creates an attestation for a user
+3. `verifyAttestation(bytes32 attestationId)`: Verifies the validity of an attestation
+
+## Frontend Components
 
-1. `POAPVerification.sol`: Integrates with the POAP protocol for verifying real-life event attendance.
-2. `AttestationService.sol`: Handles the creation of attestation schemas and the issuance of attestations using the Ethereum Attestation Service.
-3. `createMissionEnrollmentSchema()`: Creates the schema for mission enrollment attestations
-4. `createMissionEnrollmentAttestation(address recipient, uint256 tokenId)`: Creates an attestation for a user
-5. `verifyAttestation(bytes32 attestationId)`: Verifies the validity of an attestation
+- `IdentityVerification.tsx`: This component handles user identity verification by validating Ethereum addresses. It ensures that users are properly authenticated before proceeding with attestations.
+- `OnchainAttestation.tsx`: This component manages the creation of on-chain attestations, supporting both Base and Optimism L2 rollups. It integrates with the user's wallet using wagmi hooks and encodes POAP data for attestation.
