+        Hi! In order to compensate for the efforts of processing PRs, we kindly ask for a contribution.
+        See the [Pull Request Fee FAQ](https://developer.trustwallet.com/add_new_asset/pr-fee).
+        \nPlease pay
+        **$PAY1_AMOUNT $PAY1_CURRENCY**,
+        with the memo **$PAY1_MEMO**
+        to the address

         \n*Notes*:
         * Trust Wallet Tokens (TWT) are distributed to new users through our [Referral Program](https://community.trustwallet.com/t/invite-a-friend-earn-trust-wallet-token-twt/4125).
         * Payment evaluation happens when there is activity on the PR -- write a comment if you have performed the payment.
         * When payment is detected, an Accept Review is automatically placed on the PR, which is a condition for merge.  The merge is still done manually.
-        * We may waive the fee when justified.
