# Supported blockchains

The 4P Finance API supports multiple blockchains, allowing you to choose the most suitable network to send crypto assets directly to the 4P Finance wallet specified when the transaction is created.

Currently, the Off-Ramp service supports the following networks:

* **Ethereum**
* **Bitcoin**
* **HyperEVM**
* **Solana**
* **Tron**
* **Arbitrum**
* **Base**
* **Polygon**
* **BNB Smart Chain (BSC)**
* **Avalanche**
* **Optimism**

When activating your API Key with our support team, you'll specify the network and currency you want. 4P Finance will automatically handle the entire process of:

* Monitoring and confirming the crypto assets sent by your customer
* Converting the crypto assets sent
* Sending the corresponding fiat amount to the destination chosen in the request, or set in advance
* Confirming the transaction via webhook

This ensures total flexibility for your application to operate across multiple blockchain ecosystems without any operational complexity.
