What it is

The Bridge tab embeds Relay directly inside CurrentX so users can move assets cross-chain to and from MegaETH without leaving the app.

Implementation snapshot:

• UI provider: Relay (@relayprotocol/relay-kit-ui).
• In-app source tag: currentx.app.
• Route in app: /bridge.

Where to find it

• App tab: Bridge.
• Official Relay site: https://relay.link.
• CurrentX support: https://discord.gg/hebSwdXwVv.

Supported chains

Current runtime is configured for:

• MegaETH (4326 / 0x10e6)
• Ethereum
• Base
• Arbitrum
• Optimism
• BNB Chain
• Polygon

Default destination token on open is native ETH on MegaETH.

Bridge flow

1. Open the Bridge tab and connect wallet.
2. Select source chain, asset, and amount.
3. Confirm network switch in wallet if requested.
4. Review route and submit transaction(s).
5. Wait for settlement and verify funds on destination chain.

Wallet behavior

• Wallet VM scope is EVM (supportedWalletVMs = ["evm"]).
• The Bridge tab reuses the active app wallet session.
• If a live wagmi wallet client is missing, the app falls back to injected wallet adaptation.
• Destination address defaults to the connected wallet address.

Common errors

Error pattern	Meaning	Recommended action
insufficient funds	Balance is too low for amount + gas on source chain.	Reduce amount or add funds for gas.
switch / chain	Wallet is on the wrong network for the step.	Approve network switch and retry.
reject / denied	Signature or transaction was rejected in wallet.	Re-submit and approve in wallet.
no quotes available	No executable route was returned for current pair/amount.	Try another amount/token or retry later.
missing a wallet / valid wallet	Wallet session is out of sync with Relay widget.	Disconnect/reconnect wallet and retry.

Safety notes

• Keep gas funds on both source and destination chains.
• Start with a small test transfer for first-time routes.
• Verify chain/token/amount before signing.
• For unresolved failures, share wallet address and tx hash in Discord support.
