How to bridge assets to Gravity? (Galxe L1 guide)

Understanding Gravity Chain Architecture

1. Gravity is an EVM-compatible Layer 1 blockchain built on the Cosmos SDK with a focus on interoperability and developer experience.

2. It uses a modified version of the Tendermint consensus engine combined with Ethereum-style account abstraction and gas mechanics.

3. The chain supports native bridging through its Gravity Bridge module, which is distinct from third-party bridges like Wormhole or LayerZero.

4. Gravity’s native bridge operates via a multi-signature validator set that monitors Ethereum events and signs cross-chain messages using BLS signatures.

5. All bridged assets are wrapped as ERC-20 equivalents on Gravity, maintaining 1:1 backing and auditable reserves.

Prerequisites for Asset Bridging

1. Users must hold ETH in an Ethereum wallet compatible with MetaMask or Rabby to initiate bridging from Ethereum mainnet.

2. A Gravity-compatible wallet such as Keplr or Cosmostation is required to receive assets on the Gravity chain.

3. Users need sufficient ETH to cover Ethereum gas fees and a small amount of GRAVITY tokens to pay for Gravity-side transaction fees.

4. Wallets must be connected to both Ethereum and Gravity networks—Keplr supports Gravity natively, while MetaMask requires manual RPC configuration.

5. Galxe L1 campaign participants must have completed KYC verification if the bridging flow is gated by a Galxe credential check.

Step-by-Step Bridging via Gravity Bridge UI

1. Navigate to bridge.gravity.xyz and connect your Ethereum wallet first.

2. Select the asset to bridge—currently supported tokens include ETH, USDC, DAI, and WBTC.

3. Enter the amount and click “Approve” to authorize the Ethereum contract; confirm the transaction in your wallet.

4. After approval, click “Bridge” and select Gravity as the destination chain; enter your Gravity address (must be a bech32 address starting with “gravity”).

5. Confirm the second transaction on Ethereum; the Gravity Bridge relayers will process the request within approximately 15–30 minutes.

6. Once confirmed, switch your wallet to the Gravity network and verify the receipt of wrapped assets in your balance.

Galxe L1 Credential Integration

1. Galxe users who hold the Gravity Genesis NFT or have completed the “Gravity Early Adopter” quest gain priority relay queue access.

2. The Galxe passport score influences transaction batching priority—scores above 850 bypass standard confirmation delays.

3. Some bridging flows require scanning a QR code generated by Galxe’s L1 attestation service to prove chain-specific identity.

4. Users with verified Galxe credentials can use reduced gas fee tiers when bridging through the official Gravity interface.

5. Galxe-verified addresses are whitelisted for early access to newly enabled bridged assets before public rollout.

Frequently Asked Questions

Q: Can I bridge tokens from Arbitrum or Optimism directly to Gravity?A: No. Gravity Bridge only accepts assets originating from Ethereum mainnet. Tokens from L2s must first be withdrawn to Ethereum before initiating the bridge.

Q: What happens if my bridging transaction stalls on Ethereum?A: Stalled transactions usually result from low gas pricing. Users should check Etherscan for the pending transaction hash and either speed it up or cancel it using the same wallet.

Q: Are bridged assets on Gravity subject to slashing or custody risk?A: No. Wrapped assets are backed 1:1 by collateral held in the Gravity Bridge multisig. The bridge does not involve centralized custodians or staking-based slashing mechanisms.

Q: Why does my Gravity wallet show zero balance after successful bridging?A: This commonly occurs when the wallet is not configured with the correct Gravity RPC endpoint or when the token contract address is not manually added to the wallet’s token list.
