-Since both accounts are willing to accept payments in USD tokens, Holder A can send a payment of 20 USD to Holder B. Internally, Holder A’s side of the trust line is reduced by 20 USD and the Issuer’s side of the trust line is increased by 20 USD. 
+Since both accounts are willing to accept payments in USD tokens, Holder A can send a payment of 20 USD to Holder B. This appears to be a single transaction, but it actually involves two steps. Holder A sees their balance go down by 20 USD, Holder B sees their balance go up by 20 USD. Behind the scenes, though, Holder A’s side of the trust line to the Issuer is reduced by 20 USD. The Issuer’s side of the trust line is increased by 20 USD, bringing its net balance to -40 USD.

 The funds are transferred through the Issuer, but ultimately the Issuer’s balance doesn’t change. This flow of funds is known as _rippling_. Issuing accounts must allow rippling so that their holders can transfer funds to one another. 
 
+Rippling can involve several accounts as the XRPL server finds a path to transfer the funds. For example, the funds might flow between two issuer accounts that have a trust line between them.

 Other accounts such as liquidity providers and normal holders should not allow rippling. Rippling can lead to exploits where balances shift unexpectedly, funds are allocated at higher rates, and the holder ends up losing money on a transaction where they played no part.
