Bridge to Gravity
Bridge your assets to Gravity to get started.
To get started on Gravity Alpha Mainnet, you can bridge your tokens to Gravity Alpha Mainnet using the Canonical Bridge or supported third-party bridges.
See the list of bridged ERC20 token contracts deployed by Gravity team.
The Canonical Bridge
The canonical bridge is designed to connect Gravity Alpha Mainnet with Ethereum. When you bridge your tokens from Ethereum Mainnet to Gravity Alpha Mainnet, you will need to wait at least 10 minutes for the bridging process to complete. When you bridge your tokens from Gravity Alpha Mainnet to Ethereum Mainnet, after submitting the transaction, you will need to wait 7 days to claim the funds on the Ethereum Mainnet.
How to use the canonical bridge?
Visit bridge.gravity.xyz
Connect your wallet
Select Deposit or Withdraw
Select the token you would like to bridge. To see the full list of supported tokens, visit this page.
Approve, pay gas fee, and submit the transaction
Wait at least 10 mins for the transaction to be finalized
Switch to Gravity Alpha Mainnet network and you will see bridged tokens show up in your wallet
Note that you need to have both ETH and G token on Ethereum mainnet to initiate a transaction.
Why do I have to wait 7 days for withdrawing the funds to Ethereum mainnet?
This is how all optimistic rollups work. Optimistic rollups use a mechanism called fraud proofs to ensure participants in the network remain honest. There is a "challenge period" for these proofs, where, when one party submits a claim about the state of the chain, another party has approximately 7 days to challenge that claim.
Why do I need G tokens on Ethereum mainnet when I bridge other assets to Gravity Alpha Mainnet?
Bridging assets from the Ethereum mainnet to Gravity Alpha Mainnet involves two transactions. The first transaction is initiated on the Ethereum mainnet, and the second is a system transaction on the Gravity Alpha Mainnet that distributes funds to the recipient. Since Gravity Alpha Mainnet is an Arbitrum Nitro rollup, the cost of the system transaction on the Gravity Alpha Mainnet must be covered by the initiating transaction on the Ethereum mainnet. Additionally, since the Gravity Alpha Mainnet uses G tokens, the initial deposit transaction also requires some G tokens. To learn more about how canonical bridges work in general, read this article.
