How to Bridge from Solana to Arbitrum
Bridging from Solana to Arbitrum, or another layer 2 protocol like Optimism, will require users to use two cross-chain bridges. The first will move your assets from Solana to Ethereum mainnet and the second will move your assets from Ethereum to Arbitrum. While inconvenient, there are no bridges that transfer assets directly between Solana and layer 2 smart contract platforms.
You can follow this simple 4 step guide to get started:
- Visit Portal Bridge and connect your Solana Wallet.
- Select Ethereum as your destination chain and select the tokens you want to bridge and confirm your transaction.
- Once your funds arrive on Ethereum, visit Stargate Finance and connect your Ethereum Wallet.
- Select Arbitrum as your destination chain and select the tokens you want to bridge and confirm your transaction.
Fees to Bridge from Solana to Arbitrum
The cost to bridge from Solana to Arbitrum is higher than most cross-chain transactions because it will require users to bridge twice. The journey from Solana to Ethereum should cost around $15 and Ethereum to Arbitrum will be another $15-$20 depending on gas fees. This means users should expect to spend up to $50 to complete this series of transactions.
Are Portal Bridge and Stargate Safe?
Yes, Portal Bridge and Stargate Finance are the two safest bridges to use based on analysis and research conducted by our team. It is important to note that Portal Bridge has previously suffered a large exploit, however, the loss was backstopped by investors who were able to fully refund customer funds.
In conclusion, bridging from Solana to Arbitrum is a multi-step process that will require users to use two different cross-chain bridges. The transaction should cost around $50 in fees and take less than 10 minutes to complete. However, it is important to note that there are no direct bridges between Solana and layer 2 protocols like Arbitrum.
Users will first need to move their assets to Ethereum and then use a second bridge to move their assets from Ethereum to Arbitrum. Be careful of bridges that state they offer this service, because we are not currently aware of any secure and trusted platforms that offer direct Solana to layer 2 bridging.
