# Monad \[ERC-20 token payments on Monad]

The Monad payment method enables MPP payments on Monad using ERC-20 tokens. Monad supports the **charge** intent for one-time payments with two settlement modes: **push** where the client broadcasts the transfer, and **pull** where the client signs an ERC-3009 authorization for the server to broadcast.

The reference implementation is provided by [`@monad-crypto/mpp`](https://github.com/monad-crypto/monad-ts), which extends [`mppx`](https://github.com/tempoxyz/mpp) with Monad-native client and server handlers.
