+# Solas
+
+## Overview
+
+Solas is a open-source infrastructure public good for making attestations onchain on Starknet. Our motivation was EAS which is deployed on Ethereum mainnet.
+
+## Architecture
+
+We've 2 core contracts in Solas:
+- Schema Registry - This is the blueprint of the schema, it defines the structure and format of the data.
+
+- Attestation Registry - This is the contract responsible for making attestation using a schema on Starknet.
+
+## Example
+
+An example of how this could be used to attest if a person has participated in StarkHack Hackathon
+
+Raw Schema
+{
+    "name": string,
+    "userAddress": string,
+    "event": string,
+    "participated": bool
+}
+
+Example Attesation 
+
+Sender is: StarkHack admin
+Recipient is: Contestant
+revocable: false
+data: {
+    "name": "Suraj Kohli",
+    "userAddress": "0x1234567890123456789012345678901234567890",
+    "event": "StarkHack Hackathon",
+    "participated": true
+}
+
+## Future Enhancements
+
+- Ability to refer other attestations
+- Allow delegated attestations (Contract receives a signed attestation and attests onchain on behalf of user)
+- Implement Revoke
+- Implement option to refer an attestation
+
