What is Superbridge?

The Superbridge is a superchain-focused deployment of Rollbridge, servicing only Superchain mainnets and their corresponding testnets.
With Superbridge, you can bridge Ether and other tokens into and out of any supported rollup. While these rollups are usually built on top of Ethereum, this is not always the case.

Key Features of Superbridge

  • Forced Withdrawals: With our Forced Withdrawals feature, you can leverage Ethereum's censorship resistance. These withdrawals incur slightly higher gas costs because the initiating transaction must go through Ethereum.
  • Fast Withdrawals: Fast withdrawals enable chain operators to upgrade deployed contracts and customize the security around withdrawals. This logic is fully configurable, allowing the security level to be increased, decreased, or otherwise adjusted as needed by the chain.
      • Hyperlane
      Hyperlane       is Superbridge's chosen provider for modularizing the withdrawal process. By integrating with Hyperlane's relayer network, withdrawals become a single transaction operation instead of the typical three transactions required by OP stack chains, significantly enhancing the user experience for token withdrawals.
      Additionally, Hyperlane's Interchain Security Modules (ISMs) offer various options to secure the integrity of withdrawal messages, ensuring flexible and robust security measures.
  • Easy Mode: If you want to avoid the hassle of multiple transactions and the need to finalize a withdrawal after 7 days, Easy Mode is for you. For a small fee (to cover gas costs) when initiating your withdrawal, we will handle the relaying to Ethereum Mainnet and even refund any leftover ETH.
  • Native USDC Issuance with Superbridge: On supported chains such as OP Mainnet, Base, and Arbitrum, Superbridge integrates with Circle's Cross-Chain Transfer Protocol (CCTP) to issue native USDC instead of bridged USDC.
      • Unlike standard bridging with Superbridge, where funds are routed through rollup-native smart contracts, native USDC issuance involves a two-step mint and burn process via the CCTP smart contracts:
    • Burn Transaction on Origin Chain: The process begins with the user initiating a burn transaction on the origin chain. This transaction effectively burns the USDC on the source blockchain.
    • Mint Transaction on Destination Chain: After the burn transaction is confirmed, users can mint the equivalent amount of USDC on the destination chain. This ensures that the USDC remains native to the destination blockchain, maintaining its value and functionality as intended by Circle.
  • NFT Activation Campaigns: Superbridge offers NFT activation campaigns to help boost network adoption. Users who bridge ETH to your network will have an NFT minted to their address, which will be immediately available in their wallet. Each address is limited to minting one instance of the NFT.
      • How do NFT activation campaigns work?
    • Design and Configuration: Superbridge collaborates with your team to design a suitable NFT and determine the specific details and configuration of the contract.
        • Each activation campaign is fully customizable to align with the campaign's goals. Here are some common parameters that can be adjusted:
      • Duration: Specify how long the NFT activation campaign will run.
      • ETH Top-Up: Optionally rewards users with a small amount of ETH by configuring the NFT contract to include this incentive.
      • Fees: If desired, a minting fee can be configured.
      • Whitelist Mint: Enable a whitelist to allow a subset of users to mint the NFT without bridging, permitting these users to mint the NFT directly from the rollup.
    • Campaign Launch: Once the campaign is ready, it will go live on Superbridge. A banner will be added to the deployment page, informing users that they can bridge ETH to receive an NFT.
    • NFT Minting: After users bridge their funds, the NFT will be minted and available to view in any deployed NFT marketplace on the network or a special /me page on the Superbridge app.
  • Custom Development: Superbridge offers custom development services to accommodate any modifications made to your chain. The Superbridge team can collaborate with your engineering team to integrate these changes into Superbridge, ensuring a seamless user experience.

How does Superbridge work on Optimism?

This is a detailed explanation of how Superbridge integrates with chains built using the Bedrock release of the OP Stack. Chains utilizing this release include OP Mainnet, Base, Zora, and Public Goods Network, among others.
  • Deposits: A deposit is a transaction initiated on the layer 1 blockchain (e.g., Ethereum Mainnet) and executed on the layer 2 (e.g., OP Mainnet).
  • Withdrawals: Withdrawals are cross-domain transactions initiated on the layer 2 and finalized by a transaction executed on the layer 1.
  • Forced Withdrawals: Forced withdrawals provide an escape mechanism for users, allowing them to exit rollups without needing to trust rollup operators to include their transactions.
  • Easy Mode: For a small fee (to cover gas costs), when initiating your withdrawal, Superbridge will handle relaying it to Ethereum Mainnet.

How does Superbridge work on Arbitrum?

This section provides an in-depth explanation of how Superbridge integrates with chains built using Arbitrum Nitro. Chains employing this technology stack include L2s like Arbitrum One, Arbitrum Nova, and Frame, as well as Orbit L3s.
  • Deposits: A deposit is a transaction initiated on the layer 1 blockchain (e.g., Ethereum Mainnet) and executed on the layer 2 (e.g., Arbitrum Nova).
  • Withdrawals: Withdrawals are cross-domain transactions initiated on the layer 2 and finalized by a transaction executed on the layer 1.
  • Easy Mode: For a small fee (to cover gas costs), when initiating a withdrawal, Superbridge will handle relaying it to the settlement chain.
