+
+## Overview
+
+FXRP token is deployed as an [Omnichain Fungible Token (OFT)](https://docs.layerzero.network/v2/home/token-standards/oft-standard) using the [LayerZero](https://layerzero.network/) protocol.
+This enables FXRP to be transferred across multiple blockchain networks while maintaining fungibility and a unified total supply.
+
+The OFT standard allows tokens to be natively transferred between chains without the need for wrapped versions or liquidity pools, providing a seamless cross-chain experience for FXRP holders.
+
+## How It Works
+
+On Flare, FXRP uses an **OFT Adapter** contract that locks tokens when bridging to other chains.
+On destination chains, native OFT contracts mint and burn tokens as they are transferred in and out.
+
+For more details on the OFT standard and how it works, see the [LayerZero OFT documentation](https://docs.layerzero.network/v2/home/token-standards/oft-standard).
+
+## Bridge FXRP
+
+You can bridge FXRP between supported chains using [Stargate Finance](https://stargate.finance/?srcChain=flare&srcToken=0xAd552A648C74D49E10027AB8a618A3ad4901c5bE) protocol.
+
+## Deployments
+
+The following table lists the FXRP OFT contract addresses across supported chains:
