Seems there's not much more that the average person can do besides generating a new account through self-custody & storing funds there, to an address that never signs, but only receives.

Safety isn't guaranteed by storing a large sum of funds on a centralized exchange for instance, as we don't know what they're doing with the wallets holding our funds behind the scenes.

Is there anything else we can do now to best protect our coins? Any insight to crypto post-quantum? My understanding is Ethereum is far ahead of the rest of the space on this -- thanks!

MetaMask just launched a Money Sweepstakes — here's how to win up to $2,500 in mUSD this week

MetaMask Money Sweepstakes just went live! Eligible users can win up to $20,000 in mUSD across four weekly draws while still earning up to 6% APY* on your Money Account balance. Running September 17 through October 15, 2026, here's how to get started:

  • Open MetaMask Mobile and go to the Rewards tab
  • Opt into MetaMask Rewards, then opt into the Money Sweepstakes campaign
  • Tap 'Add funds' and deposit $100+ in mUSD — depositing USDC, DAI, aUSDC, or aDAI is fee-free

How entries work

You earn one entry on the day of your first eligible deposit, then one entry per calendar day you maintain a Money Account balance of $100 or more — up to 7 entries per weekly draw. If your balance drops below $100, entries pause until you top back up. Each of the four weekly draws has two randomly selected winners.

Prize pool

The weekly prize pool starts at a guaranteed $2,000 in mUSD and scales up to $5,000 once qualifying deposit volume that week hits $500,000. Each winner receives between $1,000 and $2,500 depending on how much is unlocked that week, for a total campaign prize pool of up to $20,000 mUSD.

Full details and official rules: support.metamask.io/trade/metamask-rewards/how-to-participate-in-rewards

Are you already using MetaMask Money Account? What's been your experience with it so far?

Subject to eligibility. Official Rules apply. APY is variable and not guaranteed. Not a bank account. Not available to residents of the UK, New York, or Florida, or other regions where MetaMask Money Account or mUSD is not offered.

MetaMask Agent Wallet just went public -- here's what's new in v5 and what you can actually do with it

MetaMask Agent Wallet is now open to everyone with no waitlist and no cap — sign up at metamask.io/agent-wallet. It's a self-custodial wallet that lets an AI agent trade DeFi autonomously across swaps, bridging, perpetuals on Hyperliquid, prediction markets on Polymarket, LP, and now yield vaults — all while you stay in control through spending limits, allowlists, and 2FA on anything outside your rules.

What's new in v5

  • No waitlist & no cap on participants — it’s open to everyone today!
  • 4 new chains — Robinhood Chain, Monad, HyperEVM, and MegaETH (22 supported networks total)
  • Gasless swaps & transfers are now payable in any ERC-20, so you don't need ETH sitting in your wallet to execute!
  • Atomic batched executions, meaning multiple actions are bundled into a single transaction.
  • MetaMask Earn — supply and withdraw into yield vaults via LiFi across 40+ protocols
  • Policy edits, allowing you to update your agent's spending rules at any time without re-onboarding.
  • MetaMask QR login, a new authorization method for faster access.
  • 99.56% transaction success rate heading into launch

How control works

At setup, you define which protocols the agent can interact with, which addresses it can send to, and a 24-hour spend cap. Every transaction is enforced against those rules — the agent cannot exceed your limits without your explicit approval.

Guard Mode vs Beast Mode

  • Guard Mode (recommended): Agent operates within your allowlisted protocols, networks, and a daily spend cap. Anything outside those limits triggers a push notification or email with a 5-minute approval window before it auto-declines.
  • Beast Mode: For experienced DeFi traders who want fewer interruptions. Allowlists and caps are removed, with malicious transactions still blocked by Blockaid.

Every transaction goes through a mandatory security pipeline

  • Transaction simulation — MetaMask previews exactly what a transaction will do before it executes
  • Blockaid threat scanning — malicious transactions are auto-blocked; risky ones are paused for your manual review
  • Smart Transactions — MEV protection so bots can't front-run your agent's trades
  • Transaction Shield — up to $10,000/month in coverage on eligible transactions, included for Agent Wallet with no subscription needed

Self-custody

MetaMask Agent Wallet is non-custodial — your funds are never held by MetaMask or any third party. In server wallet mode, keys are managed inside a secure enclave (TEE) so no one else can access them. If you prefer to manage your own keys, BYOK mode lets you import an existing seed phrase wallet and retain full portability outside the CLI.

Get started at metamask.io/agent-wallet! For any questions, review the docs or visit our Community Builder Hub where you can directly connect with our DevRel team for support!

Now that it's live for everyone, what’s the first thing you’re going to try with your agent? Yield strategies, perps, something else?

What data does MetaMask actually collect, and what can you turn off?

MetaMask does not collect Secret Recovery Phrases, private keys, or sell user data. Analytics (MetaMetrics) is optional and can be toggled off in MetaMask Extension or MetaMask Mobile under Settings > Security & Privacy, where you can also delete all previously collected data.

Privacy concerns about MetaMask often come up — most stem from misunderstandings about what's actually collected and what's opt-in. Here's the breakdown:

What MetaMask never collects: Your Secret Recovery Phrase (SRP) and private keys never leave your device — not to MetaMask, not to Infura, not to anyone. MetaMask does not sell your data.

What's optional: MetaMask includes an analytics system called MetaMetrics, used to improve the product. All users can opt out of MetaMetrics and delete their data at any time: Settings > Privacy > Participate in MetaMetrics. If you created your wallet with a SRP, MetaMetrics is off by default. Social login users are opted in but have the same controls and can opt out at any time.

What else you can control in MetaMask Extension and MetaMask Mobile (Settings > Security & Privacy):

• Basic functionality — covers token detection, gas estimation, and fiat conversion, using your IP address to complete the request — it is not stored or linked to your identity. You can turn it off, but some features will stop working.

• Phishing detection and Blockaid security alerts — recommended left on to best detect known phishing domains targeting onchain users..

• Transactions — data pulled from Etherscan using your address to estimate balance changes, alert you to malicious activity, and enable Smart Transactions..

For maximum privacy: You can connect MetaMask to your own Ethereum node, bypassing Infura entirely. MetaMask's codebase is fully open source on GitHub, open to audits.

Our commitment to preserving your privacy: https://metamask.io/en-GB/news/product-spotlight-privacy-preserving-features-in-metamask

MetaMask turns 10! How did a 598-line browser extension become the world's largest web3 wallet?

Ten years ago, MetaMask launched as a 598-line browser extension that removed the need to run an Ethereum node to interact with web3. Today it has 100M+ downloads, supports Bitcoin, Solana, and Tron alongside hundreds of EVM networks, and has evolved into a full financial platform. Here's a look at the decade that got us here — and where it's headed next.

The Early Years (2016–2019) — Just Get People Onchain

MetaMask launched in 2016, founded by Aaron Davis and Dan Finlay as a simple browser extension. The core idea: you shouldn't need to run an Ethereum node just to interact with web3. What seemed to be a radical simplification at the time went on to become the gateway for an entire generation of DeFi users.

DeFi Explodes & MetaMask Scales (2019–2021)

The DeFi summer of 2020 put MetaMask at the center of everything — Uniswap, Aave, Compound, OpenSea. MetaMask Swaps launched, letting users swap tokens directly in-wallet without hopping between dApps.

Security Gets Serious (2021–2023)

With an increase in scams and phishing attempts, MetaMask invested heavily in security infrastructure. Smart Transactions launched, protecting users from MEV front-running bots. According to internal 2025 data, MetaMask was blocking 6.5M+ malicious website visits, preventing ~150K malicious transactions, and saving users over $500M in potential losses annually. While no self-custodial wallet is risk-free, MetaMask has become one of the most actively protected ones.

Beyond EVM (2023–2025)

One of the biggest criticisms historically — that MetaMask was EVM-only — got answered. Bitcoin and Solana support, Tron, bridges… the wallet that started on Ethereum now works across hundreds of chains.

From Wallet to Platform (2024–2026)

MetaMask stopped being just a wallet. Fiat on-ramps, MetaMask Card, Stablecoin Earn, Perps, Prediction Markets, and the new Money Account all launched under one roof. The latest Agent Wallet addition gives AI agents full DeFi access with built-in security guardrails — a direct answer to the growing conversation of agentic wallets in crypto.

Today: 10 Years, 100M+ Downloads, and "Open Money"

Yesterday MetaMask turned 10. The team announced its next chapter under the banner of "Open Money" — building financial infrastructure that works like the internet. No intermediaries, just your money, working for you.

What's your earliest MetaMask memory — and what would you build into the next 10 years?

MetaMask just launched Money Account - here's how the yield actually works

MetaMask Money Account is a self-custodial account built into MetaMask Mobile that automatically earns yield on your mUSD — no lockups, no withdrawal penalties, no gas fees, and no account fees. Earn up to 6% APY for a limited time, through August 8th, 2026. The standard rate after the promotion ends is up to 4% APY.

What is mUSD?

mUSD (MetaMask USD) is MetaMask's official stablecoin, pegged 1:1 to the US dollar, created in partnership with Bridge and powered by the M0 protocol. It's available on Ethereum Mainnet, Linea, and Monad.

How does Money Account work?

Once you fund your Money Account, your mUSD earns yield automatically in the background — you don't need to do anything. MetaMask handles the DeFi activity on the backend through trusted third-party protocols. Your balance updates daily, and your funds are always accessible — there's no waiting period to withdraw.

Traditional crypto yield strategies often require you to manually deposit into a lending pool, pay gas fees, and wait through lock-up periods — Money Account handles all of that for you.

How to get started:

On MetaMask Mobile, select "Money". Your Money Account is already there, you just need to fund it. Supported stablecoins (USDC, USDT, DAI and their aToken equivalents) convert to mUSD with no swap or network fees. Other tokens can be deposited, but standard swap fees apply.

What else can you do with it?

Beyond earning yield, mUSD in your Money Account can be used to fund Perps or Predictions accounts directly within MetaMask Mobile, or spend mUSD with your linked MetaMask Card account directly from Money Account. You can also lend mUSD on Aave for additional rewards.

A few important notes:

  • APY is variable and not guaranteed — it changes daily with market conditions
  • The promotional rate up to 6% ends August 8th, 2026. Terms apply
  • Money Account is not available in the UK or countries on the US sanctions list
  • Money Account is self-custodial — MetaMask cannot access, freeze, or move your balance. It's secured by your SRP

More details: https://support.metamask.io/trade/money-account/

Have you tried Money Account yet — and what would you want to use the yield for?

What is MetaMask Agent Wallet and how does it keep your funds under your control?

MetaMask Agent Wallet is a self-custodial wallet that lets an AI agent trade DeFi autonomously — executing swaps, perpetuals on Hyperliquid, prediction markets on Polymarket, lending and borrowing on Aave — all while you stay in control through spending limits, allowlists, and 2FA on anything outside your rules. Currently in early access, targeting a public launch in summer 2026.

How the control model works

At setup, you’re able to configure which protocols the agent can use, which addresses it can send to, and how much it can move in a 24-hour window. MetaMask Agent Wallet enforces those rules on every transaction. The agent cannot exceed your limits without your approval.

Every transaction goes through a mandatory security pipeline

  • Transaction simulation: MetaMask checks what the transaction will do before it executes
  • Threat scanning via Bloackaid: malicious transactions are auto-blocked; anything flagged as risky gets paused and sent to you for manual approval
  • Smart transactions: MEV protection so bots cannot front-run your agent's trades
  • Transaction shield: up to $10,000 in monthly coverage on eligible transactions, included for MetaMask Agent Wallet transactions (no monthly subscription needed)

Guard Mode vs Beast Mode

  • Guard Mode (recommended): Ensures your agent operates within allowlisted protocols, networks, and a daily spend cap. Anything beyond these limits requires your approval via MetaMask Mobile push notification or email, with a 5 minute window before it auto-declines.
  • Beast Mode: For experienced DeFi traders who want fewer interruptions. Allowlists and spending caps are removed by default, with malicious transactions still blocked, requiring approval.

Self-custody

MetaMask Agent Wallet is non-custodial — your funds aren’t held by MetaMask or any third party. In server wallet setup, your keys are managed inside a secure enclave (TEE), meaning no one else can access them. If you’re a developer who prefers to manage your own keys directly, BYOK mode lets you import an existing wallet and retain full portability outside the CLI.

Early Access is free and open now! Apply at https://metamask.io/agent-wallet. Full public launch coming Summer 2026.

What MetaMask security settings should every user actually configure?

It’s easy to look over these settings, but taking the time to do so can go a long way in protecting your assets. Here’s a few that most people skip but genuinely matter:

Wallet recovery: Settings > Security and password > Manage wallet recovery. Every user should keep an offline, written down version of their secret recovery phrase (SRP). In the event you lose access to your wallet, this is the only guaranteed way to recover it. Never share your private key or SRP with anyone.

Auto lock timer: Settings > Security and password > Auto lock. Default is "Never." Set it to "After 5 minutes" so a locked wallet can't be drained by a potential malicious script running in the background of your device.

Audit your token approvals. Every dApp interaction may have granted unlimited spend permission, which don’t expire automatically. If a dApp offers a “This time only” approval option, use it. If it only shows a spending cap field, set the amount to exactly what you need— not unlimited, not the suggested default. For existing approvals, check and revoke anything stale at revoke.cash.

Verify your extension ID. Fake MetaMask extensions exist, so be sure to confirm yours at chrome://extensions. The official Chrome extension ID is nkbihfbeogaeaoehlefnkodbefgpgknn

Hardware wallet for significant holdings: MetaMask works with numerous hardware wallets. Your keys stay on the device, not within your browser. If you're holding more than you'd be comfortable losing, this is a must.
