How to bridge from ARB to Solana?

Could you please elaborate on the process of bridging assets from Arbitrum, often referred to as ARB, to the Solana blockchain? As a crypto enthusiast, I'm interested in understanding the technicalities and steps involved in such a transfer. I've heard about the importance of cross-chain compatibility and how it enables interoperability between different blockchains. However, I'm still unclear about the specific methods and tools available for bridging ARB tokens to Solana. Could you provide a step-by-step guide or explain the key considerations and potential challenges in this process?
