Ethereum to Polygon Bridging Fees

For individuals transferring assets from Ethereum to Polygon via Across Protocol, the fees are typically set between 0.06% and 0.12%. These fees account for the relayer's expenses, which are necessary for covering gas costs on Polygon and the investment of their resources.

The charges also encompass the application of the UBA model and the regulation of deposit amounts. It's important to recognize that these costs can fluctuate depending on the nuances of each transaction and the current financial state of the SpokePool.

How Does Bridging Work?

The process of bridging assets to Polygon from various blockchains, like Ethereum, is designed for secure and efficient asset transfers. Here’s a detailed breakdown of the steps involved:

1. Starting the Transfer: Users decide to move assets from Ethereum to Polygon using a compatible crypto bridge or decentralized application that supports cross-network transactions.
2. Securing Assets on Ethereum: The assets are locked within a smart contract on Ethereum, ensuring their security and temporary inaccessibility throughout the bridging procedure.
3. Minting Equivalent Assets on Polygon: To represent the original assets from Ethereum, equivalent assets are minted on the Polygon network, facilitating their use within the Polygon ecosystem.
4. Ensuring Security and Validation: The transaction undergoes authentication by validators or relayers to confirm the secure locking of Ethereum assets and the accurate minting and allocation of their Polygon counterparts.
5. Reversing the Process: To revert assets to Ethereum, the tokens on Polygon are either locked or burned, which then releases the original assets back on Ethereum.

This mechanism enhances the interoperability between Ethereum and Polygon, enabling straightforward asset transfers and broadening the utility of digital assets across these networks.
