How to Add Scroll to MetaMask in 2026 – RPC Setup Guide

You open MetaMask, you see your ETH balance on Ethereum mainnet, and then you try to do anything interesting — swap on a Layer 2 app, claim something on Scroll, send to a friend’s Scroll address — and realize your wallet is on the wrong network. Nothing lines up. Balances look empty, transactions fail, and the fix is hiding behind a form that asks for things like “RPC URL” and “Chain ID.”

This guide walks you through the whole thing: what Scroll is, why you might want it in MetaMask, and exactly how to add it — both the quick one-click method and the manual method with every field explained. By the end you’ll have Scroll Mainnet saved in your network list, you’ll know how to check you did it right, and you’ll know which mistakes and scams to watch out for.

id=”what-is-scroll”>What Scroll Is (and Why It Exists)

Scroll is a Layer 2 network built on top of Ethereum. Think of it as an express lane for Ethereum: it runs the same kinds of smart contracts and uses the same wallet addresses, but transactions typically cost less and confirm faster than on Ethereum mainnet itself. Like the other major rollups, Scroll settles its security back to Ethereum, which means your assets there inherit a connection to Ethereum’s base layer rather than depending entirely on a separate validator set.

What makes Scroll interesting to many users is its approach to compatibility. It aims to be byte-compatible with Ethereum — meaning developers can deploy Ethereum smart contracts on Scroll with little or no modification. For you as a wallet user, that compatibility is invisible most of the time; your MetaMask works the same way, your addresses are the same, and your transactions look the same. The difference is purely which network you’re connected to.

The practical upshot: when someone says “add Scroll to MetaMask,” they’re not installing new software. They’re just registering Scroll’s network settings inside a wallet you already have, so MetaMask knows where to send and receive transactions when you switch to it.

Why Add Scroll to MetaMask?

There are a few honest reasons you might want Scroll sitting in your network dropdown:

• Cheaper transactions. Moving tokens, using DeFi apps, or minting on Scroll generally costs less in gas than the same action on Ethereum mainnet. If you’re priced out of mainnet fees, that’s a real quality-of-life difference.
• Access to apps that only run there. Some protocols, NFT projects, and games deploy on specific networks. If the thing you want to use lives on Scroll, you need Scroll in your wallet.
• Lower-stakes experimentation. Trying new DeFi positions or bridging strategies is easier to stomach when each transaction costs a fraction of mainnet gas.
• Receiving funds. If someone sends you tokens on Scroll, they won’t appear in your wallet until your MetaMask knows about the network.

A fair caveat: no network is free of risk. Bridges between networks carry their own security assumptions, and smart contracts on any chain can have bugs. Adding Scroll to MetaMask doesn’t put your funds at risk by itself — it’s just a configuration entry — but using the network means the usual crypto safety rules apply.

Before You Start: What You Need

You don’t need much. Here’s the short checklist:

• MetaMask installed. The browser extension (Chrome, Firefox, Edge, Brave) or the mobile app (iOS/Android). Either one works.
• An unlocked wallet. You don’t need funds to add a network — adding it is free. You only need ETH on Scroll later if you plan to transact there.
• About five minutes. The quick method takes under a minute; the manual method a few minutes longer.

One thing worth deciding up front: which method you’ll use. The one-click method pulls pre-verified network details from a directory inside MetaMask. The manual method has you type the values yourself, which teaches you what each field means and comes in handy if the one-click list ever lags behind. Both land you in the same place.

Method 1: Add Scroll in One Click

This is the fastest route, and for most people it’s the one to use.

On desktop (browser extension):

1. Open MetaMask and unlock your wallet.
2. Click the network selector at the top of the popup — it probably says “Ethereum Mainnet.”
3. Click Add network. A list of popular networks appears.
4. Find Scroll in the list and click Add.
5. A details screen shows the network’s parameters (name, chain ID, currency symbol, explorer). Read them — they should match the values in the table below — then click Approve.
6. MetaMask adds the network and asks whether you want to Switch to Scroll. Click it.

On mobile:

1. Open the MetaMask app and tap the network selector at the top of the wallet screen.
2. Tap Add network.
3. Search for Scroll, tap Add, review the details, and tap Approve.
4. Switch to Scroll when prompted.

That’s it. Your wallet address on Scroll is the same string of characters as on Ethereum — every EVM-compatible network derives addresses the same way. The networks just keep separate balances, so don’t panic if your wallet looks empty right after switching: it’s simply showing you your Scroll balances, which start at zero.

Method 2: Add Scroll Manually, Step by Step

Adding the network by hand takes a couple of minutes and teaches you what each field does — useful knowledge whenever you add less-common networks later. As of this guide’s writing, the Scroll mainnet details are widely documented and agree across multiple references. Network parameters do occasionally change, so if something below ever looks different from what a trusted source shows, pause and double-check before continuing.

Scroll Mainnet settings:

On desktop:

1. Open MetaMask, click the network selector, then Add network.
2. At the bottom of the network list, click Add a network manually.
3. Fill in each field from the table above, copying the RPC URL and chain ID character by character. A single typo in the chain ID will make MetaMask reject the entry — that’s actually a safety feature, not a bug.
4. Click Save. MetaMask switches you to Scroll automatically.

On mobile:

1. Open the app, tap the network selector, then Add network.
2. Choose the Custom networks tab (or “Add a network manually”).
3. Enter the same five values and tap Add or Save.

A quick note on the RPC URL: the value above is Scroll’s public endpoint as widely documented. Public endpoints are fine for getting started, but they’re shared infrastructure — occasionally slow during busy periods. If transactions ever seem to hang, the network itself is usually fine; try again later or switch RPC providers. The deeper lesson, from the guide to switching networks in MetaMask safely, is to treat the RPC URL as a trust decision: MetaMask routes every request you make through it, so type it yourself from a source you trust rather than copying it from a random post.

How to Verify You Did It Right

Once Scroll is in your network list, run these checks before you move any funds:

1. Confirm the network name. The dropdown at the top of MetaMask should now offer “Scroll.” Select it.
2. Check the currency symbol. Your balance header should show ETH as the native currency.
3. Confirm the chain ID. In the extension, go to the network’s settings (network selector → Scroll → the menu). The chain ID should read 534352. If it reads anything else, remove the entry and re-add it.
4. Look at the explorer link. If you added an explorer URL, the “View on block explorer” option should open ScrollScan showing an empty address page for your wallet. That’s the expected result for a fresh setup.
5. Send a tiny test transaction first. If you plan to bridge funds to Scroll, move a small amount first and confirm it arrives before sending the rest. This single habit prevents more losses than any other tip in this guide.

If Scroll doesn’t appear in the dropdown after saving, close and reopen the extension or app. MetaMask occasionally needs a refresh to render a newly added network.

Common Mistakes (and How to Fix Them)

Most setup problems fall into a short list. Work through them here before reaching out to anyone for help — and be careful about who you ask, as the next section explains.

“Chain ID does not match” error. This means the chain ID you typed doesn’t agree with what the RPC endpoint reports. The fix is almost always a typo: re-enter 534352 carefully. Don’t “fix” it by changing the RPC URL to something random — that would defeat the check’s purpose.

Network added but doesn’t show up. Close the extension (or force-quit the app) and reopen it. Newly added networks sometimes need a UI refresh before they render in the dropdown.

Wallet looks empty after switching. Normal. Each network keeps its own balances. Your Ethereum-mainnet ETH hasn’t gone anywhere; switch back to Ethereum Mainnet to see it. Funds only exist on Scroll if you bridged or received them there.

Tokens sent to Scroll aren’t visible. Native ETH appears automatically, but other tokens may need to be imported manually. In MetaMask, go to the Tokens tab, choose Import, and paste the token’s contract address on Scroll — a contract address from Ethereum mainnet won’t work. Find contract addresses on ScrollScan, the chain’s block explorer, by typing its URL yourself.

Transaction stuck or failing. If you have zero ETH on Scroll, nothing can move — you need a small amount for gas. Bridge a little ETH over (start with a test amount) or receive some from another wallet. If you do have gas and transactions still fail, check whether the RPC endpoint is responding; public endpoints occasionally degrade, and waiting a while or switching providers usually resolves it.

Accidentally added Scroll twice. Harmless. Remove the duplicate via Settings → Networks, keeping the entry whose chain ID reads 534352.

Staying Safe: Phishing RPC Scams

Here’s the part most setup guides skip, and it’s the most important one. When a website asks you to “add a network” or “switch network,” MetaMask shows you the exact parameters before you approve. Scammers exploit this in two ways:

• Fake “add network” prompts on phishing sites. A lookalike site — maybe a misspelled DeFi app — triggers a network-add request with a malicious RPC URL. If you approve it, the attacker’s server sits between you and the chain: it can show you fake balances, hide real transactions, and generally lie to your wallet. Always read the details screen before approving, and only add networks from the built-in list or from parameters you typed yourself.
• Fake support reaching out. No legitimate support team will ever contact you first about your wallet, ask for your seed phrase, or ask you to screen-share while you type network details. Anyone who does is a scammer, full stop. The fake support playbook is depressingly effective — a dedicated companion setup guide on adding networks to MetaMask walks through the same phishing patterns you’ll see here.

Two more habits that cost nothing: bookmark the sites you actually use, and type explorer and RPC addresses yourself instead of clicking links in messages, emails, or social posts. The crypto version of phishing is overwhelmingly URL-based, and the defense is boring but effective.

The Bottom Line

Adding Scroll to MetaMask takes about five minutes and costs nothing: use the one-click method for speed, or type the network details yourself — chain ID 534352, RPC https://rpc.scroll.io/, currency ETH — for full control. Verify the chain ID before you approve anything, start with a small test transaction, and treat every unexpected network prompt as guilty until proven innocent.

Once Scroll is in your network list alongside your other chains, switching between networks becomes second nature — and the same careful habits apply everywhere. If you’re adding more networks soon, the Soneium setup guide follows the same pattern, so the process will feel familiar.
