Bridge Assets back to Ethereum (Gravity Alpha, L2)

Move G and other assets from Gravity Alpha Mainnet (L2) back to Ethereum mainnet.

Action required — bridge out before November 1, 2026. Please move all of your assets off Gravity Alpha Mainnet (L2) back to Ethereum before November 1, 2026. The network is unsettled in December 2026.

Different assets use different routes, and they are not interchangeable — see Which route does my asset use? below before you start.

This page covers withdrawing assets from the legacy Gravity Alpha Mainnet (L2, chainId 1625) to Ethereum mainnet. To bring assets in, see How to Get G (on Gravity Alpha Mainnet, L2).

Which route does my asset use?

Gravity Alpha Mainnet holds two different kinds of tokens, and each kind has exactly one way out.

USDC, USDT and ETH/WETH cannot be withdrawn through the canonical bridge. These tokens were issued on Gravity Alpha Mainnet by Stargate, not by the Arbitrum standard gateway — the rollup's canonical bridge has no record of them and cannot process them. Stargate is the only way to move them off this network. Do not wait for another route to appear.

Bridge G (and DAI, WBTC) back to Ethereum — official Gravity bridge

Use the official Gravity Bridge (native canonical route) to move G from Gravity Alpha Mainnet back to Ethereum mainnet.

Open https://bridge.gravity.xyz/ and connect your wallet.
Set the source network to Gravity Alpha Mainnet and the destination to Ethereum.
Select G, enter the amount, and submit the withdrawal transaction — the native canonical route is used automatically for G.

The native canonical bridge also handles DAI and WBTC the same way.

7-day withdrawal delay. Like all optimistic rollups, native withdrawals from Gravity Alpha Mainnet to Ethereum have a ~7-day challenge period before the funds can be claimed on Ethereum. Start well before the November 1, 2026 deadline so your withdrawal has time to complete. If you need G on Ethereum sooner, a liquidity-pool route such as Symbiosis can bridge G in minutes instead of the 7-day wait.

Bridge USDC, USDT and ETH/WETH back to Ethereum — Stargate

For USDC, USDT and ETH/WETH, use Stargate. Stargate uses liquidity pools (Stargate V2 Hydra), so transfers settle in minutes — there is no 7-day rollup wait.

Open https://stargate.finance/bridge and connect your wallet.
Set From to Gravity (Alpha Mainnet) and To to Ethereum — or any other chain Stargate supports.
Select the asset, enter the amount, and confirm.

On Stargate, USDC is listed as USDC.e — not USDC. If you search for "USDC" you may not find your balance. The three assets appear as USDC.e, USDT and WETH with Gravity as the source network.

Stargate can also send these assets directly to chains other than Ethereum — including BNB Chain, Base, Arbitrum, Polygon, Avalanche, OP Mainnet and others — so you do not have to route through Ethereum if your destination is elsewhere.
