Bridge to Scroll Network

WHAT IT DOES

This tool enables you to bridge ETH from Ethereum Mainnet to Scroll, a leading zkEVM Layer 2 solution that uses zero-knowledge proofs for scalability and security. It reads your current ETH balance on Ethereum Mainnet, the Scroll bridge contract details, and the current gas price to provide an accurate cost estimate before you commit. The tool then constructs and submits a transaction to the Scroll bridge contract, depositing your specified amount of ETH to the Scroll network, where it becomes available as Scroll-native ETH.

Scroll is a zkEVM (zero-knowledge Ethereum Virtual Machine) rollup that offers full EVM compatibility while significantly reducing transaction fees. The bridge uses the official Scroll bridge infrastructure to securely transfer ETH from Ethereum to Scroll, making it easy to onboard to the Scroll ecosystem and access its growing DeFi applications. As a zk-rollup, Scroll provides strong security guarantees backed by zero-knowledge proofs.

HOW TO USE

Connect your wallet using the "connect" button. Ensure you are connected to Ethereum Mainnet (chain ID 1) — the tool will display your current chain ID and ETH balance. Enter the amount of ETH you wish to bridge to Scroll in the input field. The tool will display the bridge contract address and estimate the gas cost for the deposit transaction.

Review the bridge summary, then click "bridge ETH to Scroll" to sign and submit the transaction through your wallet. The tool will wait for confirmation and display the transaction details on Etherscan. After the transaction is confirmed on Ethereum Mainnet, your funds will be processed by the Scroll bridge and will appear on Scroll. This process typically takes a few minutes, depending on network congestion and Scroll's zk proof generation and verification process.

TECHNICAL MECHANISM — SCROLL ZK-ROLLUP BRIDGE DEPOSIT

The tool interacts with the Scroll L1StandardBridge contract, which serves as the entry point for depositing ETH from Ethereum to Scroll. The bridge's depositETH() function accepts ETH as value and handles the underlying mechanics of submitting a transaction to the Scroll inbox contract. The bridge uses a combination of Ethereum layer 1 transactions and Scroll's zkEVM messaging protocol to securely transfer assets between chains.

When you submit a deposit, the bridge contract sends your ETH to the StandardBridge, which then forwards it to the Scroll bridge's inbox contract. The Scroll sequencer processes the inbox transaction, credits your account on L2 with the equivalent amount of Scroll-native ETH, and produces a receipt. Scroll's zkEVM proof system then generates a zero-knowledge proof that validates the correctness of the L2 state transition, including your deposit. This proof is submitted to Ethereum Mainnet, where it is verified by the Scroll verification contract. Once verified, the deposit is considered finalized. The zk proof generation adds an additional layer of security, making Scroll one of the most secure Layer 2 solutions available, as the proof mathematically guarantees the correctness of the state transition.

WHAT IT CANNOT SEE

This tool cannot estimate exact gas costs without a live RPC call, and gas prices on Ethereum Mainnet may change between quoting and execution. It cannot guarantee bridge finality times — while typical deposits take minutes, network congestion or zk proof generation delays may extend this time. The tool cannot verify the bridge contract address is correct beyond the pre-configured mapping, and if the mapping becomes outdated, the transaction could fail or be sent to the wrong contract. It cannot cancel a transaction once submitted, and if the transaction fails due to gas issues or contract errors, you may still pay gas fees. The tool cannot handle bridging from non-Ethereum chains, nor can it bridge tokens other than ETH. It also does not support bridging from Scroll back to Ethereum or handling of ERC-20 tokens.

PLEASE NOTE — ETHEREUM MAINNET ONLY

This tool works exclusively on Ethereum Mainnet (chain ID 1). You must be connected to Ethereum Mainnet to use this tool. It does not support bridging from other networks such as Polygon, BNB Smart Chain, or from Scroll back to Ethereum. The tool only bridges native ETH — it does not support ERC-20 tokens or other assets. Always verify that you are connected to the correct network and that the bridge contract address displayed matches the official Scroll bridge address before submitting a transaction. Using the wrong network or an outdated contract address will result in transaction failure and loss of gas fees. Scroll uses the same ETH token as Ethereum, so your bridged ETH will be usable immediately on Scroll applications.
