 If you are using an [EOA](https://ethereum.org/en/developers/docs/accounts/#types-of-account) wallet you can use the same address. If your Ethereum mainnet wallet is a contract (e.g. a multisig) then you must specify an [Arbitrum wallet address](/arbitrum/arbitrum-faq/#what-do-i-need-to-do-to-use-the-graph-on-l2) where your transfer will be sent. Please check the address carefully as any transfers to an incorrect address can result in permanent loss. If you'd like to use a multisig on L2, make sure you deploy a multisig contract on Arbitrum One.
 
+Wallets on EVM blockchains like Ethereum and Arbitrum are a pair of keys (public and private), that you create without any need to interact with the blockchain. So any wallet that was created for Ethereum will also work on Arbitrum without having to do anything else.
+
+The exception is with smart contract wallets like multisigs: these are smart contracts that are deployed separately on each chain, and get their address when they are deployed. If a multisig was deployed to Ethereum, it won't exist with the same address on Arbitrum. A new multisig must be created first on Arbitrum, and may get a different address.

 ### What happens if I don’t finish my transfer in 7 days?
 
 The L2 Transfer Tools use Arbitrum’s native mechanism to send messages from L1 to L2. This mechanism is called a “retryable ticket” and is used by all native token bridges, including the Arbitrum GRT bridge. You can read more about retryable tickets in the [Arbitrum docs](https://docs.arbitrum.io/arbos/l1-to-l2-messaging).

 Yes! The process is a bit different because vesting contracts can't forward the ETH needed to pay for the L2 gas, so you need to deposit it beforehand. If your vesting contract is not fully vested, you will also have to first initialize a counterpart vesting contract on L2 and will only be able to transfer the delegation to this L2 vesting contract. The UI on Explorer can guide you through this process when you've connected to Explorer using the vesting lock wallet.
 
+### Does my Arbitrum vesting contract allow releasing GRT just like on mainnet?
+
+No, the vesting contract that is created on Arbitrum will not allow releasing any GRT until the end of the vesting timeline, i.e. until your contract is fully vested. This is to prevent double spending, as otherwise it would be possible to release the same amounts on both layers.
+
+If you'd like to release GRT from the vesting contract, you can transfer them back to the L1 vesting contract using Explorer: in your Arbitrum One profile, you will see a banner saying you can transfer GRT back to the mainnet vesting contract. This requires a transaction on Arbitrum One, waiting 7 days, and a final transaction on mainnet, as it uses the same native bridging mechanism from the GRT bridge.

 ### Is there any delegation tax?
 
 No. Received tokens on L2 are delegated to the specified Indexer on behalf of the specified Delegator without charging a delegation tax.
