How to bridge to Scroll

A real case from June 2026: a user bridged 5.9971 WETH (~$9,999) from Mantle and received 5.9425 WETH on Scroll 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. Mantle as source, Scroll as destination — the WETH sat in a Mantle wallet and the goal was access to Scroll DeFi (Ambient, SyncSwap).
Connected wallets. MetaMask on the Mantle side, MetaMask on the Scroll side. Symbiosis resolved the destination address automatically from the connected wallet — no manual paste required.
Entered the amount. 5.9971 WETH (~$9,999). The Mantle wallet had enough balance to cover network gas.
Reviewed the quote. Symbiosis displayed the exact WETH amount on Scroll, 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 Mantle transaction in MetaMask. WETH arrived in MetaMask within ~39 sec. The transaction is fixed on-chain — verifiable on Symbiosis Explorer, Symbiosis Explorer, and Scrollscan.

About the Mantle to Scroll route

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

Hundreds of transactions have moved through this route in the last quarter, with top inbound sources from Base, Mantle, Ethereum.

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

Popular routes to Scroll: Arbitrum Bridge, Base Bridge, Soneium Bridge, Katana 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

What is Scroll in blockchain?

Scroll is a zkEVM rollup, a Layer 2 network that uses zero-knowledge proofs to settle transactions back to Ethereum while keeping fees low and throughput high. Because it's EVM-equivalent, the same wallets, tools, and smart contracts you use on Ethereum work on Scroll with minimal changes. Users bridge assets like WETH, USDbC, and SIS into Scroll to swap, provide liquidity, and interact with its growing ecosystem.

How do you bridge from Base to Scroll?

Open the Symbiosis bridge widget, set Base as the source chain and Scroll as the destination, then choose your token and amount. Connect your wallet, confirm the quote and the routing fee, and approve the transaction. Base is currently the top inbound source to Scroll on Symbiosis at 23.7% of volume, with most transfers settling in about 20 seconds.

How much does it cost to bridge crypto to Scroll?

On Symbiosis the routing fee is flat and predictable: bridging 100 USDC, 500 USDC, 1,000 USDC, or 5,000 USDC all carry a 0.25 USDC fee. So a 100 USDC transfer delivers ~99.36 USDC and a 5,000 USDC transfer delivers ~4,985 USDC. You'll also pay the standard source-chain gas on top of that routing fee.

How does a blockchain bridge work?

A bridge moves value between two separate networks that can't natively talk to each other, locking or burning the asset on the source chain and releasing the equivalent on the destination. Symbiosis routes this non-custodially through its routing engine, so you keep control of your funds the entire time. On the Scroll route the median delivery is 20 seconds, with the 90th percentile at 42 seconds.

What is the safest crypto bridge for Scroll?

Symbiosis is non-custodial and audited, with no KYC required, so you bridge to Scroll without handing over custody or personal data. The Scroll route has handled $45K in volume across 190 transactions from 77 unique wallets over the last 90 days, growing 77% quarter over quarter. Transfers are consistently fast, with a 20-second median and 42 seconds at the 90th percentile.

What is the Scroll network?

The Scroll network is an Ethereum Layer 2 built as a zkEVM rollup, meaning it inherits Ethereum security through validity proofs while offering cheaper, faster transactions. It supports the standard Ethereum tooling, so developers and users move over with little friction. Bridging in lets you use assets such as WETH (33.2% of bridged volume here), USDbC, and SIS across the Scroll ecosystem.

What is the Scroll ecosystem?

The Scroll ecosystem is the collection of DeFi apps, DEXs, wallets, and tools running on the Scroll zkEVM Layer 2. To participate you first bridge assets in, with the most common tokens being WETH, USDbC, and SIS by volume. Inbound liquidity arrives from chains like Base, Mantle, Ethereum, Arbitrum One, and Polygon through the Symbiosis routing layer.

What does a crypto bridge do?

A crypto bridge lets you move tokens from one blockchain to another, for example transferring WETH or USDbC from Ethereum, Base, or Arbitrum One onto Scroll. Symbiosis does this without custody of your funds and without KYC, routing the transfer in roughly 20 seconds on the Scroll path. It removes the need to manually sell on one chain and rebuy on another.
