CROSS-CHAIN GUIDE

How to bridge to Blast

A real case from June 2026: a user bridged 3.6210 WETH (~$6,231) from Ethereum and received 3.6213 ETH on Blast 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, Blast as destination — the WETH sat in an Ethereum wallet and the goal was access to Blast DeFi with native yield.
Connected wallets. MetaMask on the Ethereum side, MetaMask on the Blast side. Symbiosis resolved the destination address automatically from the connected wallet — no manual paste required.
Entered the amount. 3.6210 WETH (~$6,231). The Ethereum wallet had enough balance to cover network gas.
Reviewed the quote. Symbiosis displayed the exact ETH amount on Blast, 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. ETH arrived in MetaMask within ~62 sec. The transaction is fixed on-chain — verifiable on Symbiosis Explorer, Etherscan, and BlastScan.

What is Blast blockchain?

Blast is a yield-native Ethereum Layer 2, meaning ETH and stablecoins bridged onto it can earn native yield by default.

Through the Symbiosis routing layer, WETH currently accounts for 100% of bridged volume onto Blast.

How do I bridge to Blast?

Open the bridge widget, connect your wallet, and select your source chain — most inbound volume comes from Arbitrum One (57.9%) and Ethereum (42.0%). Choose WETH, enter the amount, confirm the quote, and approve the transaction. Median delivery is around 24 seconds, with 90% of transfers landing within 39 seconds.

How do I bridge from Blast to ETH?

Select Blast as your source chain in the widget, pick WETH, and choose your destination such as Ethereum, where it arrives as native ETH. Confirm the live quote, then approve the transaction in your wallet. The transfer is non-custodial and typically settles in about 18 seconds at current routing speeds.

How much does it cost to bridge to Blast?

The routing fee is a flat 0.0003 WETH across quote tiers. For example, bridging 0.05 WETH delivers 0.0494 WETH, 0.25 WETH delivers 0.2491 WETH, and 1 WETH delivers 0.9970 WETH. Each route completes in roughly 18 seconds.
