CROSS-CHAIN GUIDE

How to bridge to Scroll

Example quote from 25 September 2026: sending 3,000 USDC (~$3,000) from Ethereum returns about 1.1190 ETH on Scroll via Symbiosis, estimated ~15 sec — 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 how the flow works:

Pick the source. Set Ethereum as source and Scroll as destination — the USDC sits in an Ethereum wallet, and the goal is access to Scroll DeFi (Ambient, SyncSwap).
Connect wallets. MetaMask on the Ethereum side, MetaMask on the Scroll side. Symbiosis reads the destination address automatically from the connected wallet — no manual paste required.
Enter the amount. 3,000 USDC (~$3,000) in this example. Keep enough ETH in the wallet to cover network gas.
Review the quote. Symbiosis displays the exact ETH amount on Scroll (about 1.1190 ETH in this example), the flat Symbiosis fee in USD, and ETA (~15 sec). The quote is locked in before signing — 2% slippage tolerance protects against sudden price moves.
Sign and confirm. Sign the Ethereum transaction in MetaMask. ETH arrives in MetaMask once the route completes — track the transfer on Symbiosis Explorer.

About bridging to Scroll

Why this route. Scroll is a zkEVM rollup: it executes Ethereum bytecode and proves its batches to Ethereum with zero-knowledge proofs. People bridge in to trade on DEXes such as Ambient, SyncSwap and Honeypop.
What you receive. ETH on Scroll, the network's gas coin, swapped from USDC on Ethereum; one signature from you starts the route.
Watch out for. Each Scroll transaction carries two fee parts, an L2 execution fee and an L1 data fee, both in ETH, so leave a little extra aside. SCR is Scroll's governance token and cannot pay gas. Select Scroll mainnet (chain ID 534352), not Scroll Sepolia.
Speed. Across all routes into Scroll, median delivery 12 seconds; 90th percentile 29 seconds, over the 90 days to 25 September 2026.

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.

Still have questions?

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, USDC, 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.

How much does it cost to bridge crypto to Scroll?

On Symbiosis the fee grows with the amount: on 28 September 2026, bridging 1,000 USDC from Ethereum carried a $3.74 fee and 10,000 USDC carried a $31.77 fee (full cost in the Symbiosis app plus gas). A 1,000 USDC transfer delivered 0.3766 ETH and a 10,000 USDC transfer delivered 3.765 ETH, with the exchange rate already reflected in the amount received.

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 12 seconds, with the 90th percentile at 29 seconds as of September 2026.

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. Transfers are consistently fast, with a 12-second median and 29 seconds at the 90th percentile as of September 2026.

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, USDC, 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. 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 USDC from Ethereum, Base, or Arbitrum One onto Scroll. Symbiosis does this without custody of your funds and without KYC, routing the transfer in roughly 12 seconds on the Scroll path as of September 2026. It removes the need to manually sell on one chain and rebuy on another.
