The quickest answer to how to bridge to MegaETH is to open Rabbithole, MegaETH’s official portal, connect an EVM wallet such as MetaMask or Rabby, and either bridge through its built-in LI.FI router or convert USDC to USDm at 1:1. Third-party routes listed by MegaETH include Across, Stargate, deBridge, Relay, Bungee, Jumper and Wormhole’s Portal. Advanced users can send ETH straight into the OP Stack Standard Bridge contract on Ethereum. Gas on MegaETH is paid in ETH, so bring a little even if you are mainly moving stablecoins.
- MegaETH opened its public mainnet on February 9, 2026; the MEGA token followed on April 30, 2026.
- ETH is the native and gas token, so every wallet needs a small ETH balance.
- Rabbithole offers two in-house paths: LI.FI swaps and bridges, and a USDC-to-USDm converter.
- The canonical bridge is OP Stack’s Standard Bridge with a small patch; exits go through a Kailua dispute system, not the usual seven-day OP window.
- New chain, new risks: L2BEAT does not yet rate MegaETH even Stage 0, so size deposits accordingly.
MegaETH at a Glance
MegaETH is an Ethereum layer 2 built for real-time performance, with very short block times aimed at trading, games and other latency-sensitive apps. It is fully EVM compatible, so standard Ethereum wallets, token standards and contracts work without changes. If you are new to rollups generally, our layer 2 primer explains why chains like this settle back to Ethereum.

| Dispute system | Kailua, a ZK fraud-proof design built on RISC Zero |
| Explorers | Blockscout and Etherscan |
| Stablecoins you will meet | USDm (MegaETH’s dollar token) and USDT0 |
Route 1: The Rabbithole Portal (Official MegaETH Bridge)
MegaETH’s user documentation names Rabbithole as the official place to get funds on mainnet. Once your wallet is connected, the bridge tab gives you two choices.
LI.FI swap-and-bridge
This is the general-purpose option. LI.FI aggregates bridges and DEXs, so you can start with ETH on Arbitrum, USDC on Base or a token on another supported chain and receive ETH or a stablecoin on MegaETH in one flow. The interface shows an estimated arrival time before you confirm. Compare the “you receive” figure rather than the headline fee, because swap slippage is folded into it.
USDm Bridge
The USDm Bridge converts USDC into USDm at a 1:1 rate. USDm is the dollar token MegaETH launched with, issued in partnership with Ethena; governance discussions on Aave describe it reaching MegaETH via LayerZero. Retail users generally exit USDm through DEX liquidity or bridges rather than direct redemption, so check pool depth before parking large amounts in it.
Fund tab (card or bank)
If you have no crypto yet, Rabbithole’s fund tab connects to a fiat on-ramp that sells ETH or stablecoins with a debit card, credit card or bank transfer. Expect identity checks and on-ramp fees set by the provider.
Route 2: Bridge USDT0 to MegaETH With Third-Party Bridges
MegaETH maintains a list of third-party bridges at the bottom of the Rabbithole bridge page. As of October 2026 it included:
- Across – supported MegaETH from launch day for ETH and USDT0; relayers front funds, so arrivals usually take seconds.
- Stargate – LayerZero-powered; the route MegaETH highlights for USDT0 and USDm.
- deBridge – useful when starting from Solana; its fee page lists a flat 0.001 ETH protocol fee for orders created on MegaETH, plus a 4 basis point variable fee.
- Relay, Bungee and Jumper – aggregators and intent routers that pick a path for you.
- Portal (Wormhole) – for USDC, ETH, SOL and many other tokens across 30-plus chains.
Avail’s Nexus-powered FastBridge also announced day-one MegaETH support from more than a dozen ecosystems. Our ranking of the best crypto bridges covers how Across, Stargate and deBridge differ in security design.
If your goal is specifically to bridge USDT0 to MegaETH, Stargate and Across are the two routes MegaETH itself names for it. USDT0 is Tether’s omnichain USDT built on LayerZero’s OFT standard: USDT is locked on Ethereum and an equal amount is minted on the destination, so you are not relying on a pool of wrapped IOUs.
Route 3: The MegaETH Canonical Bridge (Advanced)
MegaETH documents a direct method for ETH: send ETH to the OP Stack Standard Bridge contract on Ethereum mainnet at 0x0CA3A2FBC3D770b578223FBB6b062fa875a2eE75. Once the Ethereum transaction is finalized, the same amount minus Ethereum gas appears at your address on MegaETH. The docs label this “advanced users only” for good reason:
- Sending to the wrong contract, or sending an ERC-20 token by plain transfer, can lose funds.
- You wait for Ethereum finality (roughly 13 to 15 minutes) instead of seconds.
- You pay mainnet gas, which is usually more than a fast bridge’s fee for small amounts.
Verify the address against MegaETH’s documentation and a block explorer yourself before using it; do not trust a copy from social media, including this page if it is ever scraped and altered.
Adding MegaETH to Your Wallet
MegaETH works with any Ethereum-compatible wallet; the docs mention MetaMask and Rabby by name. The simplest way to add the network is to let Rabbithole or a bridge prompt your wallet to add it. If you add it manually, take the chain ID and RPC URL from MegaETH’s “Connect” documentation page or a reputable chain directory, set the currency symbol to ETH, and point the explorer to Blockscout or Etherscan’s MegaETH instance. A wrong chain ID is a common sign of a malicious RPC, so cross-check the number in two places.
Withdrawing From MegaETH: Why the Exit Takes Days
Deposits into MegaETH are quick. Withdrawals through the canonical bridge are not, and the timing differs from other OP Stack chains. MegaETH settles with Kailua, which keeps the optimistic model (proposals are assumed valid unless disputed) but resolves disputes with a single zero-knowledge proof instead of a long interactive game. L2BEAT’s listing describes a resolved proposal becoming usable for withdrawals after an execution delay of about three and a half days, with a Guardian role able to review state roots during that window.
Two further points from L2BEAT matter for anyone moving serious money:
- Only whitelisted proposers can publish state roots to Ethereum, so if they stop, withdrawals through the canonical bridge freeze.
- MegaETH did not yet meet L2BEAT’s Stage 0 requirements at the time of writing, meaning users depend heavily on the operators behaving correctly.
In practice, most users exit through the same liquidity bridges they came in on. Across, Relay or Stargate pay you out on the destination chain within minutes, and the bridge provider waits out the canonical delay instead of you. The trade-off is a small fee and reliance on that bridge’s own security. Our guide on whether bridging crypto is safe covers how to weigh that.
How to Bridge to MegaETH: Options Compared
| Route | Assets | Speed in | Speed out | Cost profile |
|---|---|---|---|---|
| Rabbithole LI.FI | ETH, stablecoins, many tokens | Minutes (shown before confirming) | Same path in reverse | Aggregated bridge fee plus any swap slippage |
| Rabbithole USDm Bridge | USDC to USDm | Minutes | Via DEX or bridges | Advertised 1:1 conversion plus gas |
| Across | ETH, USDT0 | Seconds | Seconds to minutes | Dynamic relayer fee, quoted live |
| Stargate | USDT0, USDm | Minutes | Minutes | LayerZero messaging plus protocol fee |
| deBridge | Wide range, incl. from Solana | Seconds to minutes | Seconds to minutes | Flat fee in native gas token plus 4 bps |
| Canonical OP Stack bridge | ETH (advanced) | About Ethereum finality | Several days (Kailua delay) | Ethereum gas only |
New-Chain Checklist Before You Bridge
MegaETH is young, its stablecoin is young, and its ecosystem attracted a lot of attention around the token launch. That combination is exactly what phishing crews target. Run through this list each time:
- Reach Rabbithole from MegaETH’s docs, not from a sponsored search result or a reply on X.
- Check the token contract for USDm or USDT0 on the explorer before buying; copycat tokens with the same ticker are common on new chains.
- Start with a modest amount and confirm it lands before moving the rest.
- Keep ETH for gas on MegaETH and, if you plan a canonical withdrawal, on Ethereum too.
- Revoke approvals you granted to experimental apps once you are done with them.
- Treat “pre-deposit” or “points” bridges with caution. MegaETH itself refunded an earlier pre-deposit raise and re-audited the contract involved, which shows how quickly launch-phase mechanics can change.

FAQ
What is the best MegaETH bridge for ETH?
For speed, Across or Relay usually deliver ETH to MegaETH within seconds for a small quoted fee. For lowest protocol risk on larger sums, the canonical OP Stack bridge avoids third-party relayers but takes about as long as Ethereum finality on the way in and several days on the way out. Rabbithole’s LI.FI tab compares several of these automatically.
Can I bridge USDT0 to MegaETH?
Yes. MegaETH lists Stargate as a route for USDT0 and USDm, and Across supported USDT0 from launch. USDT0 uses LayerZero’s OFT model, so USDT is locked on Ethereum and minted on MegaETH rather than swapped through a wrapped pool. You still need a little ETH on MegaETH to move it afterwards.
How long does a MegaETH canonical bridge withdrawal take?
Longer than a deposit. MegaETH uses the Kailua dispute system, and L2BEAT describes an execution delay of roughly three and a half days before a resolved state can be used for withdrawals, plus proving and finalizing steps on Ethereum. Check the bridge interface or L2BEAT for the current figure before you start.
Do I need MEGA tokens to pay gas on MegaETH?
No. MegaETH’s documentation lists ETH as both the native currency and the gas token. MEGA, which launched on April 30, 2026, is the network’s separate token. Make sure your wallet holds a small ETH balance on MegaETH before trying to transfer USDm, USDT0 or other tokens.
