MegaETH Wallet Guide: Send ETH and USDm on a Real-Time L2

How MegaETH addresses work

MegaETH is EVM compatible, so your account is a normal 0x address derived from your recovery phrase. Keylo shows the same address under MegaETH as under Ethereum, Base or Arbitrum, and validates its checksum before you send. There is no account activation, no minimum balance and no memo or tag.

The speed of the chain does not change how addresses behave, but it does change how quickly mistakes become final. A transfer to the wrong address confirms within moments, leaving no time to cancel. Copy addresses rather than typing them, compare the first and last characters, and use a small test amount the first time you pay someone new.

Create a MegaETH wallet in Keylo

1. 1

   Go to Keylo registration in any modern browser on desktop or mobile.

2. 2

   Sign up with your name, email, phone and password, and confirm your email address.

3. 3

   Keylo generates your 12-word recovery phrase in the browser and encrypts it locally with a key derived from your password. Only the encrypted copy reaches the server.

4. 4

   Reveal and write down the phrase in Settings after re-entering your password.

5. 5

   Select MegaETH from the network list to see your 0x address and ETH balance.

How to receive ETH on MegaETH

1. 1

   Open MegaETH in Keylo and choose ETH or the token you expect, such as USDm.

2. 2

   Tap Receive. Keylo shows the address, its QR code and the MegaETH network label.

3. 3

   Copy the address or let the sender scan the QR code.

4. 4

   On an exchange, pick MegaETH as the network only if it is listed. Otherwise withdraw to a supported network such as Ethereum, Base or Arbitrum and bridge across.

5. 5

   Check Activity. Deposits on MegaETH itself confirm almost instantly once broadcast.

How to send ETH on MegaETH

Because the chain is new, exchange support for MegaETH deposits is still uneven. Before you send to an exchange, open its deposit page and confirm it lists MegaETH for that exact asset. If it does not, bridge to a network the exchange supports first. A deposit on an unsupported network may need a manual recovery request that can take weeks, if the exchange accepts it at all.

1. 1

   Open MegaETH in Keylo and choose the asset.

2. 2

   Paste or scan the recipient's address. Keylo checks the checksum and warns you about contract addresses.

3. 3

   Enter an amount or tap Max, which keeps ETH aside for the fee.

4. 4

   Pick a fee speed. On a chain this fast, normal speed is almost always enough.

5. 5

   Review the summary with the network fee and exact amount, then confirm. The transaction is signed in your browser.

How MegaETH fees work

MegaETH charges fees in ETH using the familiar EVM format: gas used multiplied by a base fee plus a priority tip. Because transaction data is stored on EigenDA rather than in Ethereum blobs, the data component of each fee is much smaller than on rollups that post everything to Ethereum, and the network is designed to keep base fees low even at high throughput.

MegaETH also uses its stablecoin to support low fees. Reserve income from USDm is meant to cover the sequencer's operating costs, so the network can run without adding a large margin on top of fees. That design aims for cheap and stable costs, but it depends on the stablecoin's reserves and on the operator, so fees can still change as the network evolves.

Keylo shows the exact network fee before you confirm and adds nothing to normal sends. Keep a little ETH on MegaETH even if you mostly hold USDm, because tokens cannot pay their own transfer fees. If you arrive with only stablecoins, a small swap into ETH through Keylo's swap screen fixes that, though the swap itself also needs a little ETH, so bridge some ETH first when you can.

Tokens on MegaETH: USDm, USDT0 and MEGA

MegaETH supports ERC-20 tokens, which Keylo can show and send. USDm is the network's native dollar stablecoin, issued with Ethena on its USDtb infrastructure and backed mainly by tokenized US Treasury funds and liquid stablecoins. USDT0, the omnichain Tether token, was the bridged stablecoin available at launch. MEGA is the ecosystem token, and wrapped ETH is common in trading apps.

USDm and USDT0 are different tokens with different issuers and contracts, so check which one an app or exchange expects. Being a new, fast chain with lots of trading activity, MegaETH also attracts copycat tokens and fake MEGA claim pages. Verify contracts on the MegaETH explorer and ignore tokens and links you did not ask for.

Swap and bridge on MegaETH, and why official withdrawals are slow

Most people reach MegaETH through a bridge, and Keylo's swap and bridge screen handles that from inside the wallet. LI.FI searches decentralized exchanges and audited bridges for a route, and THORChain adds native swaps for coins like BTC. The quote lists where your funds will travel, the expected amount, the minimum you will accept and every fee, including any small service fee. You can watch a bridge until it arrives; if a cross-chain route fails to complete, the protocol refunds the wallet that sent it.

MegaETH's canonical bridge to Ethereum uses a challenge period of seven days followed by an extra execution delay, so an official withdrawal can take well over a week, with steps to complete on Ethereum that cost mainnet gas. Liquidity bridges skip that wait: a relayer pays you on the destination chain from its own funds and settles later, which is why most people move funds in and out through routes like the ones Keylo quotes.

Deposits are faster than withdrawals in every case. Bridging ETH or USDT0 onto MegaETH from another layer 2 typically completes within seconds to minutes, and you can start using apps as soon as the funds land. Plan the exit before you go in: know which route you will use to leave, and what it costs, before committing a large amount.

Is MegaETH safe for your funds?

MegaETH trades some decentralization for speed. A single sequencer orders and executes everything, data lives on EigenDA rather than Ethereum, and upgrades can happen without a long timelock. Its proof system lets challengers dispute bad state, but trackers flag that too few independent parties can do so today. None of this means funds are unsafe in ordinary use, but it does mean you rely more on the operator than on a mature rollup like Arbitrum.

A sensible approach is to keep the amount you need for apps on MegaETH and hold long-term savings on a more established network. Compare the trade-offs in the Arbitrum guide if you want a rollup with a longer track record.

MegaETH safety tips

• Check exchange support for MegaETH deposits before sending; use a bridge if it is missing.
• Keep ETH for gas; MEGA and USDm cannot pay fees.
• Verify USDm, USDT0 and MEGA contracts before swapping.
• Send a test amount first, since transfers finalize too quickly to cancel.
• Use liquidity bridges for exits unless you are prepared to wait more than a week.
• Never share your recovery phrase; Keylo support will never ask for it.
