How to bridge to Metis

A real case from June 2026: a user bridged 10.0000 WETH (~$17,746) from Ethereum and received 10.0000 WETH on Metis via Symbiosis — no wrapped tokens beyond the standard route, fully non-custodial. Symbiosis works as a liquidity meta-aggregator, comparing routes across multiple DEXes and bridge providers and picking the best one by price, fee, and speed automatically. This is one of the most popular flows on this corridor; the same widget supports any source chain and token combination. Here's the exact flow:

Picked the source. Ethereum as source, Metis as destination — the WETH sat in an Ethereum wallet and the goal was access to Metis Andromeda DeFi.
Connected wallets. MetaMask on the Ethereum side, MetaMask on the Metis side. Symbiosis resolved the destination address automatically from the connected wallet — no manual paste required.
Entered the amount. 10.0000 WETH (~$17,746). The Ethereum wallet had enough balance to cover network gas.
Reviewed the quote. Symbiosis displayed the exact WETH amount on Metis, the flat Symbiosis fee in USD, and ETA. The quote was locked in before signing — 2% slippage tolerance protects against sudden price moves.
Signed and confirmed. Signed the Ethereum transaction in MetaMask. WETH arrived in MetaMask within ~202 sec. The transaction is fixed on-chain — verifiable on Symbiosis Explorer, Etherscan, and Metis explorer.

About the Ethereum to Metis route

The Metis corridor on Symbiosis routes WETH, ETH and 100+ other tokens through the optimal mix of DEXes and bridge providers, with destination tokens delivered natively on Metis.

Hundreds of transactions have moved through this route in the last quarter, with top inbound sources from Ethereum, BNB Chain, Arbitrum One.

The corridor is non-custodial — funds remain in the user's wallet at every step, and the same widget supports the reverse direction (Metis). No sign-up, no KYC.

Popular routes to Metis: Arbitrum Bridge, Base Bridge, Unichain Bridge, Mantle Bridge.

Audited in the open

Two-layer staking security

Cross-chain transactions routed via Octopools AMM (scans liquidity across DEXs and chains for minimal slippage), then signed by an MPC group via Threshold Signature Scheme (TSS) — no single party can move user funds. Two security layers: Symbiosis PoS Staking (SIS-collateralised relayer nodes) + Symbiotic restaking (additional slash-able collateral). 2/3 stake quorum for epoch changes.

Two-layer staking security

$8B+ across 54 chains

$8B+ total volume bridged across 5M+ transactions from 800K+ unique wallets. Supports 54 networks — more than any other cross-chain bridge (Across 35+, deBridge 30+, Allbridge 20). EVM + non-EVM in one route — Ethereum, Solana, BNB Chain, TON, Tron, Bitcoin, Arbitrum, Polygon, and 46 more. Per-transaction range: $10 to $140,000 — handles retail swaps and whale trades on the same route.

FAQs

How do I bridge to Metis?

Connect your wallet to the Symbiosis widget, then pick your source chain and token — most users bridge from Ethereum (66.7% of inbound volume) or BNB Chain (28.2%), typically sending WETH or ETH. Enter the amount, confirm the live quote, and approve the transaction. Delivery is fast, with a median of 38 seconds and 75 seconds at the 90th percentile.

What is the safest crypto bridge?

Symbiosis is non-custodial, audited, and requires no KYC, so you keep control of your funds the entire way through. Over the last 90 days the Metis routing layer has settled $53K across 28 transactions for 22 unique wallets, with a median delivery time of 38 seconds. No bridge is risk-free, but a self-custodial, audited design with transparent on-chain performance is a strong baseline.

How much does it cost to bridge Metis?

The Symbiosis routing engine charges a flat fee of 0.0003 WETH per transfer across the current quote tiers. For example, bridging 1 WETH delivers 0.9981 WETH, and 5 WETH delivers 4.9894 WETH. Smaller transfers like 0.05 WETH arrive as 0.0495 WETH after the fee.

How do I add Metis to MetaMask?

Open MetaMask, go to the network selector, and choose to add a custom network using the official Metis RPC and chain details. Once added, you can switch to Metis and see your bridged balances directly in the wallet. After bridging through Symbiosis, your WETH or ETH will appear under the Metis network.

What does Metis do?

Metis is a decentralized-sequencer Layer 2 network designed to scale Ethereum with lower fees and faster confirmations. Users bridge assets in to swap, transact, and interact with applications on the L2. On the Symbiosis routing layer, the most-bridged assets here are WETH (71.8%) and ETH (28.2%).

Why is ETH not showing up in MetaMask?

If your bridged funds don't appear, first confirm MetaMask is switched to the Metis network rather than Ethereum. Most transfers settle quickly — median 38 seconds, up to about 75 seconds at the 90th percentile — so allow a moment before refreshing. You may also need to manually add the token to make the balance visible in your wallet.

How do I swap on Metis?

Use the Symbiosis widget to bridge your asset onto Metis first, selecting a source chain like Ethereum or BNB Chain. Once your WETH or ETH lands on the network, you can swap it within the Metis ecosystem. Bridging is non-custodial and typically completes in under a minute.
