AMP is like sending several puzzle pieces through different mail carriers, ensuring that only when all parts arrive do they form a complete payment. Instead of relying on a single path in the Lightning Network, AMP divides the total amount into smaller chunks, routing each through potentially different channels. This helps avoid capacity bottlenecks and increases the likelihood of a successful payment.

From the receiver’s perspective, the funds only finalize when all partial payments come in, preventing scenarios where you get stuck with incomplete amounts. AMP’s design also preserves privacy: observers can’t easily tell these smaller parts belong to the same overall payment. While a bit more complex under the hood, AMP adds significant flexibility to the Lightning Network, making it more robust for larger payments.
