How to configure MetaMask for Gravity Chain? (Omnichain Access)

Network Configuration Essentials

1. Gravity Chain operates as an omnichain execution layer with native support for cross-chain message passing and unified account abstraction. Its chain ID is 1984, distinct from Ethereum Mainnet (1) or Polygon (137).

2. The official RPC endpoint is https://rpc.gravitychain.io. This node is maintained by the Gravity Foundation and serves low-latency block confirmation with sub-2-second finality.

3. Currency symbol must be set to GTV, not ETH or any wrapped variant. This reflects the native gas token used across all Gravity Chain domains.

4. Block explorer URL should point to https://explorer.gravitychain.io. This interface indexes transactions, contracts, and cross-chain bridges in real time without caching delays.

5. MetaMask must have “Allow custom chains” enabled under Settings → Experimental Features. Disabling this option blocks contract verification during deployment or interaction.

Wallet Initialization Protocol

1. After adding Gravity Chain, users must manually import at least one valid Gravity Chain address using private key or keystore file — mnemonic phrases generated on Ethereum do not auto-map due to differing derivation paths.

2. The default HD derivation path is m/44'/60'/0'/0/0, matching Ethereum EIP-1581 but requiring explicit selection during account import in MetaMask Advanced Settings.

3. Imported accounts show zero balance initially even if GTV exists on-chain; users must trigger a manual sync via “Refresh account” in MetaMask’s account dropdown menu.

4. Signing requests fail silently if the connected dApp uses outdated ABI definitions; verify that the interface references Gravity Chain’s canonical contract addresses published on gravitychain.io/contracts.

5. Transaction nonce errors occur when switching between Gravity Chain and other EVM networks without clearing pending queue — use “Reset Account” under Advanced Settings before reconnection.

Cross-Chain Bridge Integration

1. Gravity Chain supports direct bridging from Ethereum, BSC, Arbitrum, and Optimism through its native Omnibridge smart contracts, accessible only after wallet address registration on bridge.gravitychain.io.

2. Registration requires signing a typed message via MetaMask using EIP-712 standards — failure results in “Unauthorized bridge access” error regardless of token balance.

3. Deposited assets appear as wrapped tokens (e.g., wETH-GTV) with 1:1 peg; these are non-transferable outside Gravity Chain until withdrawn via the same bridge interface.

4. Withdrawal confirmations require two signatures: one from user wallet, another from Gravity Chain validator set — average wait time is 3.7 minutes per withdrawal batch.

5. Gas refunds for failed bridge operations are credited automatically within six blocks, visible only in GTV denomination, not source-chain currency.

Security Validation Checks

1. All Gravity Chain contract interactions must validate the CHAIN_ID parameter inside Solidity logic — dApps omitting this check expose users to replay attacks across parallel EVM chains.

2. MetaMask displays “Unverified Contract” warnings for any deployed bytecode not listed in Gravity Chain’s verified repository at github.com/gravitychain/verified-contracts.

3. Phishing detection engines flag domains lacking TLS 1.3+ and DNSSEC — ensure dApp URLs resolve to IPFS gateways with CID v1 hashes embedded in page headers.

4. Hardware wallet integration remains unsupported for Gravity Chain signing; Ledger Live and Trezor Suite return “Invalid network code” unless firmware version exceeds 2.52.1.

5. Revoke permissions for unused dApps via MetaMask’s “Connected Sites” panel — Gravity Chain-specific approvals persist independently from Ethereum permissions and require individual revocation.

Troubleshooting Common Failures

1. “Invalid Chain ID” appears when MetaMask detects mismatched chain ID during signature request — confirm chain ID field matches exactly 1984 with no leading zeros or whitespace.

2. “Provider Error: Timeout” signals RPC node congestion — switch to backup RPC https://backup-rpc.gravitychain.io which mirrors primary data with 12-second lag.

3. “Transaction rejected by user” occurs even after confirmation prompt if browser extension conflicts exist — disable all non-essential Web3 extensions including WalletConnect wrappers and Rainbow injectors.

4. “Insufficient funds for gas” triggers despite GTV balance because Gravity Chain enforces dynamic base fee calculation per block — check current fee rate at rpc.gravitychain.io/fee before submission.

5. “Nonce too low” persists after reset if local storage contains stale transaction records — clear IndexedDB entries labeled “gravitychain” and “web3-provider” in Chrome DevTools Application tab.

Frequently Asked Questions

Q: Can I use the same MetaMask seed phrase for Gravity Chain and Ethereum without risk?A: Yes, but only if you explicitly select the correct derivation path during account import. Default Ethereum paths do not yield valid Gravity Chain addresses.

Q: Why does my GTV balance show zero after bridging from Arbitrum?A: Balance updates require manual refresh after bridge confirmation. Click “Refresh account” in MetaMask and verify transaction status on explorer.gravitychain.io.

Q: Is it safe to approve unlimited token allowances on Gravity Chain?A: No. Unlimited allowances expose assets to malicious contract upgrades. Always specify exact amounts and revoke after use via revoke.gravitychain.io.

Q: Do hardware wallets support Gravity Chain staking functions?A: Not currently. Staking interfaces require software wallet signing due to complex multisig validation flows unsupported by Ledger or Trezor firmware.
