-## Linking Attestations
-
-Verax Attestation Registry allows creating links ("relationships") between attestations.  
-🔗 Go to the [official documentation](https://docs.ver.ax/developer-guides/for-attestation-issuers/link-attestations)
-for more details
-
-Verax offers 2 Schemas to cover most use cases:
-
-- The **Relationship** Schema, with ID `0x41b8c81288eebbf173b2f54b9fb2f1d37f2caca51ef39e8f99299b53c2599a3a`
-- The **Named Graph Relationship** Schema with ID `0x8f83a0ef7871f63455a506f6bca0db98a88721764ae6dbde2afddd8e12e442b8`
-
-## Off-chain Attestations
-
-To handle large payloads to attest and avoid increasing the gas cost for the attestation process, it is possible to host
-the attested payload off-chain. In this case, the on-chain attestation will only contain a link to the attested payload,
-based on a dedicated Schema called **Offchain**. It is available with ID
-`0xa288e257097a4bed4166c002cb6911713edacc88e30b6cb2b0104df9c365327d`.
-
-To use it, simply pass a payload with the following content:
-
-```json
-{
-  "schemaId": "0x41b8c81288eebbf173b2f54b9fb2f1d37f2caca51ef39e8f99299b53c2599a3b",
-  "uri": "https://example.com/payload/123"
-}
-```
-
-- `schemaId`: the ID of the Schema encoding the complete (off-chain) payload
-- `uri`: the link to the complete (off-chain) payload
