+
+
+Licensed Work:        Aave Migration Contracts
+                      The Licensed Work is (c) 2023 Aave DAO, represented by its governance smart contracts
+
+Additional Use Grant: You are permitted to use, copy, and modify the Licensed Work, subject to
+                      the following conditions:
+                      - Your use of the Licensed Work shall not, directly or indirectly, enable, facilitate,
+                        or assist in any way with the migration of users and/or funds from the Aave ecosystem.
+                        The "Aave ecosystem" is defined in the context of this License as the collection of
+                        software protocols and applications approved by the Aave governance, including all
+                        those produced within compensated service provider engagements with the Aave DAO.
+                        The Aave DAO is able to waive this requirement for one or more third-parties, if and
+                        only if explicitly indicating it on a record 'authorizations' on govv3.aavelicense.eth.
+                      - You are neither an individual nor a direct or indirect participant in any incorporated
+                        organization, DAO, or identifiable group, that has deployed in production any original
+                        or derived software ("fork") of the Aave ecosystem for purposes competitive to Aave,
+                        within the preceding two years.
+                        The Aave DAO is able to waive this requirement for one or more third-parties, if and
+                        only if explicitly indicating it on a record 'authorizations' on govv3.aavelicense.eth.
+                      - You must ensure that the usage of the Licensed Work does not result in any direct or
+                        indirect harm to the Aave ecosystem or the Aave brand. This encompasses, but is not limited to,
+                        reputational damage, omission of proper credit/attribution, or utilization for any malicious
+                        intent.
