NOTE: the Ethereum<>Polygon bridge is now deprecated. The below information is retained for record-keeping purposes only.

To bridge your RNDR (POL) to RENDER (SOL), get step-by-step instructions: https://know.rendernetwork.com/general-render-network/rndr-to-render-what-you-need-to-know/using-the-solana-upgrade-assistance-tool

and then go to polygon.rendernetwork.com to begin your upgrade.

RNDR ERC-20 Tokens on the Polygon Mainnet need to be bridged to RNDR ERC-20 Tokens on the Ethereum Mainnet in order to be upgraded to Solana SPL Tokens through the Upgrade Portal.

If you need to bridge RNDR Tokens on the Polygon Mainnet, first locate your RNDR ERC-20 Tokens by switching to the Polygon Mainnet in Metamask (or other supported wallets that support Matic and the Polygon Bridge). For the purposes of this guide, Metamask is used as an example.

Note: You will only be able to upgrade from Polygon to Solana once via our Upgrade Portal.

Click the Dropdown by the Ethereum Mainnet Symbol.

And then select the Polygon Mainnet

If the RNDR Tokens do not automatically appear in your wallet, you may need to import the tokens.

Click Import tokens and enter the RNDR ERC-20 Polygon Contract address in the 'Token Contract address' field: 0x61299774020dA444Af134c82fa83E3810b309991 The RNDR symbol should auto-populate, and click 'Next.' Your RNDR ERC-20 Polygon token balance should appear and click 'Import'.

Reminder: You will only be able to upgrade once from Polygon to Solana via our Upgrade Portal.

Now that your tokens are successfully imported, you can bridge using Polygon's native bridge: https://portal.polygon.technology/bridge

[please note: bridging using Polygon's bridge will take approximately 45 minutes to an hour]

Click Connect Wallet using your wallet of choice.

Select 'Polygon POS' in the Transfer from dropdown menu, select the RNDR Token in the token drop down menu on the Right, and select 'Ethereum' in the Transfer to dropdown menu, and click Bridge. [Note: You will need a small amount of Polygon tokens in your account to pay the transaction fees in order to bridge]

Confirm the transaction in your wallet and wait for the Bridge to complete (roughly 45 minutes).

Once this completes you will need to Claim your tokens on the Ethereum Mainnet. To do so, click Add RNDR to wallet in order to import the RNDR ERC-20 contract on the Ethereum Mainnet. You will be prompted to switch back to the Ethereum Mainnet, click 'Switch network' and then 'Add token' on the Ethereum Mainnet.

Once the Bridge completes, a popup will ask you to claim the RNDR ERC-20 tokens on the Ethereum Mainnet. Click Claim, set the Ethereum gas fee, and click Confirm.

Once the transaction completes, your RNDR tokens are bridged to the Ethereum Mainnet and you are able to upgrade them to RENDER SPL tokens on Solana using the Upgrade Portal. Please see here for guide on using the RENDER SPL token upgrade assistant tool.
