Omnichain Fungible Token (OFT)
Overview
FXRP token is deployed as an Omnichain Fungible Token (OFT) using the LayerZero 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 how the OFT standard works, see the LayerZero OFT documentation.
DVN Security Stack
LayerZero V2 uses Decentralized Verifier Networks (DVNs) to verify cross-chain message integrity before execution. Each app configures its own security stack by selecting one or more DVNs, instead of relying on a single shared verifier.
For FXRP OFT routes that include Flare, the following DVNs are used:
| DVN Provider | Flare DVN Address |
|---|---|
| LayerZero Labs | 0x9c061c9a4782294eef65ef28cb88233a987f4bdd |
| Nethermind | 0x9bcd17a654bffaa6f8fea38d19661a7210e22196 |
| Canary | 0xd791948db16ab4373fa394b74c727ddb7fb02520 |
| Horizen | 0xeaa5a170d2588f84773f965281f8611d61312832 |
See LayerZero DVN Providers documentation for deployment details, and LayerZero V2: Explaining DVNs for the conceptual model.
Bridge FXRP
You can bridge FXRP between supported chains using Stargate Finance protocol.
