A cross currency swap is similar to a vanilla swap, while giving each counterparty access to a different foreign currency. That is, one counterparty makes payments in one currency; the other makes payments in a different currency.
Because there are two currencies involved (and therefore two notionals) the payments made not only include interest rate payments (on the set payment periods in the relevant currency on the respective principal) but also an exchange of principals at maturity and (optionally) at the start of the swap.
In a typical inflation swap, two counterparties agree on a long-term contract based on an agreed inflation rate. If, at the end of the contract, prices are higher than originally expected, the seller of inflation makes a payment to the buyer. If prices turn out lower than expected, the buyer pays the seller.
