| Cross-chain payments involve transferring value across different blockchain networks, which can be difficult due to the absence of direct interoperability. To address this challenge, Hashed Time Lock Contracts (HTLCs) offer a solution by facilitating atomic swaps. These swaps guarantee that transactions are either executed in full or not at all, eliminating the possibility of partial transfers. | ||

| To ensure stability in cross-chain payments, the assets utilized in different blockchain networks must maintain a fixed swap ratio. For instance, the Bitcoin payment channel exclusively supports BTC. Meanwhile, CKB can incorporate a wrapped BTC token via the UDT channel, establishing a consistent 1:1 ratio with Bitcoin. |

I reality, the swap ratio will change with time, how can we keep it up to date?

Assume that wrapped BTC is always 1:1 with BTC, or use an external script to get the ratio when proposing the exchange order.
