# How to use Base to Arbitrum Bridge — 2026 Guide
Because both Layer 2 networks share your Ethereum wallet address, a Base to Arbitrum bridge through [Rezentix](https://rezentix.com/) wraps up in as little as two minutes and rarely passes ten. This direct rollup-to-rollup path is built for DeFi users shifting liquidity between ecosystems without waiting out a seven-day native withdrawal challenge.
### Action Plan for a Base to Arbitrum Bridge
Step 1: Bring In the Sending Wallet on Base
Unlock your browser extension and make sure it is switched to chain ID 8453 before initiating the session.
Step 2: Pick the Two Networks on Screen
[The Rezentix interface](https://rezentix.com/) detects Base as your starting point and lets you lock in Arbitrum as the destination.
Step 3: Enter What Moves in ETH
Type your transfer quantity while keeping a few bucks of ETH behind for gas on both [Arbitrum](https://arbitrum.io/) and Base.
Step 4: Destination Address Check on Arbitrum
Verify that your own 42-character hexadecimal account populates automatically as the receiving target on the destination rollup.
Step 5: Sign Once the Numbers Look Right
Inspect the combined rollup deduction and approve the transaction prompt inside your connected wallet window.
Step 6: Look Up the Arrival on Arbitrum
Switch your wallet network selector to Arbitrum One to see the newly credited funds in your account.
### Shared EVM Accounts Across Both Rollups
When you bridge Base to Arbitrum, you don't have to juggle two separate browser extensions or worry about incompatible character formats. Both networks are Ethereum Layer 2 rollups that use identical 0x public keys. One identical hex string on both ends.
That shared structure cuts out the riskiest part of cross-chain transfers: manual copy-and-paste mistakes. Your connected wallet signs the outbound transaction on chain ID 8453, and the funds arrive at that exact same account on Arbitrum One.
Speed is the other major advantage of skipping Ethereum mainnet as an intermediate stop. Base produces new blocks every two seconds (with Arbitrum matching sub-second soft confirmations on the receiving side), so wallet balances refresh almost immediately after the relayer clears.
### Sample Math on a $300 Rollup Transfer
Walking through a concrete scenario makes moving Base to Arbitrum easy to picture. Say you have $300 worth of ETH sitting on Base and want to deploy it into an Arbitrum liquidity pool this afternoon.
You leave $5 of ETH behind in your Base wallet for future gas and set the transfer amount to $295. On the confirmation summary, the Base execution cost reads $0.15 and the rollup routing fee comes to $1.65, putting the total expense at $1.80. After you click approve in Rabby, the transaction settles in about three minutes, crediting $293.35 worth of ETH on Arbitrum One.
### Field Notes on ETH Gas and Arbiscan Verification
Anyone learning how to bridge Base to Arbitrum should remember how native tokens work on the destination side. While ARB exists as the governance token for the ecosystem, every transaction on Arbitrum One is still billed in ETH. Moving every last fraction of ETH out of your Base wallet is an easy error that leaves you unable to pay for the approval signature, and arriving on Arbitrum without ETH leaves your tokens stranded.
If your wallet extension doesn't show the new funds right away, you won't need to guess where they are. Pasting your receiving address into Arbiscan is the cleanest way to verify the incoming credit when a wallet interface lags behind.
Network configuration rarely causes friction since most modern wallets pre-load both rollups. Still, if you ever need to verify RPC endpoints or chain ID 8453 parameters manually, the official [Base documentation](https://base.org/) publishes the verified connection details.
### Pre-Send Verification Before Approving on Chain 8453
* Active Network Check: Confirm your wallet banner displays Base (chain ID 8453) rather than Ethereum mainnet before typing your send amount.
* ETH Buffer on Both Sides: Leave a small slice of ETH untouched on Base for the signature, and make sure you'll hold ETH on Arbitrum for subsequent swaps.
* Slippage and Net Output: Glance at the minimum received line on the summary panel to verify liquidity depth for your token size.
* Self-Custody Destination: Keep the receiving address set to your own 0x wallet rather than pasting a smart contract or exchange deposit address.
### What You Pay Between Chain 8453 and Arbitrum
Expect the total cost for this rollup-to-rollup crossing to land between $1 and $6. Because neither side touches Ethereum Layer 1 execution directly during a liquidity-routed hop, you avoid the steep mainnet gas spikes that used to make smaller transfers impractical.
That $1 to $6 range covers both the local L2 execution signature on Base and the relayer fee for delivering funds on Arbitrum. Treat the numbers above as a baseline weather report; the exact deduction locked into your wallet signature is what you actually pay.
### Quick Answers
#### Do I Need ARB Tokens to Pay for Gas After My Funds Arrive?
No, Arbitrum One uses ETH as its native gas currency for every transaction. ARB is strictly a governance token, so you only need ETH in your wallet to trade, lend, or transfer funds after they land.
#### Can I Send Funds to a Different 0x Wallet on Arbitrum?
Yes, you can override the auto-filled destination box and paste a different Ethereum-compatible 0x address if you want to fund a hardware wallet or a second account. Just verify that the receiving address isn't a centralized exchange deposit contract that ignores cross-chain credits.
#### Why Does This Route Finish Faster Than the Official Rollup Bridge?
Native rollup withdrawals pass through Ethereum mainnet and enforce a seven-day fraud-proof challenge window. Using a liquidity router swaps against settled pools on both rollups, cutting the wait down to a few minutes.
[Pull up the Rezentix panel](https://rezentix.com/) if your Base wallet holds extra ETH for gas and you want funds on Arbitrum now. Both rollups use the same 0x account, so you won't even need to copy a second address. Switch your wallet network to Arbitrum One as soon as the transaction clears to put your arrived balance to work.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://vizar.gitbook.io/tutorials/base-to-arbitrum-bridge/how-to-use-base-to-arbitrum-bridge-2026-guide.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
