# Platform Chain (P-Chain) API

關於 p-chain
> The primary function of this is for staking AVAX and serving as a validator. If you’re a validator (or delegating to a validator), then your AVAX rewards will be received on this chain. It’s also possible to receive transfers from the other two Avalanche chains (X and C). If you have no interest in staking AVAX, then you don’t need to worry about this one at all!
