L2 ROLLUP · OP STACK

Block Explorer for Mode Network

Ethernal is a hosted block explorer for Mode Network (chain ID 34443) that connects to your RPC endpoint and provides real-time transaction decoding, contract verification, and DeFi protocol debugging. Mode is a DeFi-focused OP Stack chain with Sequencer Fee Sharing (SFS), rewarding developers with a share of the sequencer revenue their contracts generate. Deploy a full-featured explorer in under 5 minutes.

Sequencer Fee Sharing Visibility

Mode's signature feature is Sequencer Fee Sharing (SFS): developers register their contracts with the SFS contract (0x8680CEaBcb9b56913c519c069Add6Bc3494B7020) and earn a portion of the sequencer fees their contracts generate. Ethernal decodes SFS registration and claim transactions, so you can track exactly how much revenue each contract earns.

L2-to-L1 Withdrawal Tracking

Mode follows the standard OP Stack withdrawal lifecycle: initiation on L2, state proposal, 7-day challenge window, proving, and finalization on Ethereum. Ethernal tracks each step in real time so your users always know exactly where their withdrawal stands, whether they are bridging ETH, USDC, or any ERC-20 token back to L1.

How to Set Up a Mode Network Block Explorer

Create a workspace

Connect your Mode RPC

Paste your Mode RPC endpoint. For Mode mainnet, use https://mainnet.mode.network or any supported provider.

Configure OP Stack bridge monitoring

Enter your OptimismPortal and Batch Inbox addresses for Mode. Ethernal starts monitoring deposits, withdrawals, and batches automatically.

Go live

Point your custom domain (e.g. explorer.mode.example) to your Ethernal workspace. Your explorer is live with transaction decoding, contract verification, and bridge tracking.

Mode Explorer Options Compared

Teams building on Mode typically choose between the Mode Explorer (Blockscout-based), a self-hosted Blockscout instance, or Ethernal (hosted with OP Stack-native features and SFS visibility).

Frequently Asked Questions

How do I set up a block explorer for Mode Network?

Create a workspace on Ethernal, paste your Mode RPC endpoint (e.g. https://mainnet.mode.network), configure the OP Stack bridge addresses, and point your custom domain. The whole process takes under 5 minutes.

What is Mode's Sequencer Fee Sharing (SFS)?

SFS is Mode's developer incentive mechanism. When you register your smart contract with the SFS contract (0x8680CEaBcb9b56913c519c069Add6Bc3494B7020), you earn a share of the sequencer fees that your contract generates. Ethernal decodes SFS registration, claim, and transfer transactions.

Can I use Ethernal to debug DeFi protocols on Mode?

Yes. Ethernal decodes all function calls, internal calls, and events from DeFi protocols on Mode. For multi-hop swaps on Kim Exchange or lending operations on Ionic, you see the full call trace with decoded parameters, making it easy to identify exactly where a transaction fails or how liquidity flows.

Is Mode an OP Stack chain?

Yes. Mode is built on the OP Stack and is part of the Optimism Superchain. It settles on Ethereum L1 and uses the standard OP Stack withdrawal lifecycle with a 7-day challenge period. Ethernal has native support for all OP Stack features including deposit monitoring, withdrawal tracking, and batch/blob monitoring.

Does Mode use EIP-4844 blobs?

Yes. Mode adopted EIP-4844 blobs after the Ethereum Dencun upgrade (March 2024), posting transaction data as blobs instead of calldata to reduce L1 costs. Ethernal tracks both blob and calldata batches in the batch explorer view.
