How to Bridge from Polygon to Solana Bridge

As outlined above, the best way to bridge from Polygon to Solana, and vice versa, is through the Portal Bridge. Their platform allows you to connect your MetaMask Wallet, Phantom Wallet, or other Web3 wallet to seamlessly transfer assets between both blockchains. They charge zero fees and offer minimal slippage when moving assets cross-chain.

Here is a simple 4 step breakdown on how to get started:

  1. Visit Portal Bridge and select your Source Chain (e.g Polygon) and Target Chain (e.g Solana).
  2. Connect your EVM Wallet (e.g MetaMask) and your SOL Wallet (e.g Phantom).
  3. Select the token you want to bridge and the amount.
  4. Preview the transaction and click 'Send'. The funds will arrive on your destination wallet in under 10 minutes.

What are the Fees?

The fees to bridge between SOL and Polygon are very cheap because both networks are low-fee blockchains. Based on our testing, we found that transactions under $1,000 USD in value will cost less than $5 when moving assets in either direction. Above that value, it can get as high as $20 depending on the total amount and the bridge liquidity at time of transfer.

Is Portal's Polygon to Solana Bridge Safe?

Portal Bridge is the largest and most popular Solana bridge for EVM to SOL cross-chain transfers. That said, it does not come without its risks. Portal has previously been exploited for over $80 million, which means it does have a history of vulnerabilities. However, these smart contract issues have since been patched and are less likely to re-occur.

For an alternative option, you can always use a centralized exchange like Bybit or Binance that offers withdrawals to the SOL network. With this method, you can deposit ETH or USDC to your Polygon wallet on a centralized exchange, and then withdraw to a SOL wallet.

Bottom Line

Bridging assets directly between the Polygon Layer 2 and Solana Layer 1 network is possible through the Portal Bridge, which allows users to transfer ETH, USDC, WBTC, and other tokens between Polygon, Solana, and 30 other networks. The process is simple and only takes four steps, and fees are low for transactions under $1,000 USD.

While there have been past vulnerabilities in the Portal Bridge, these have been patched and are less likely to occur. An alternative option is to use a centralized exchange like Bybit or Binance that offers withdrawals to the SOL network.
