ChainEye

ChainEye is a free, open-source suite of omni-chain analytical tools built for Web3 retail investors. Incubated by Biteye, one of Asia's leading Web3 research communities, the platform aggregates data across Ethereum and its growing Layer 2 ecosystem, giving everyday users access to bridge-cost comparisons, on-chain dashboards, and wallet-level analytics that would otherwise require juggling a half-dozen separate tools.

The project launched in Q4 2021 and has accumulated over 200,000 user visits. In 2023, ChainEye won the tools category at the ETH Shanghai Hackathon — recognition that validated its approach of bundling practical, cost-saving analytics into a single free interface.

The Core Philosophy: Public Goods Analytics

What distinguishes ChainEye from commercial analytics platforms is its commitment to staying free and open source. The codebase is published under the AGPL-3.0 license on GitHub, meaning anyone can inspect, fork, or contribute to the underlying code. Revenue from paid tiers or proprietary data subscriptions does not fund the project. Instead, ChainEye has received grants from Gitcoin (Grant Round 15), Optimism RPGF, the NEAR Aurora Foundation, the Graph Foundation, and Chainbase. That public-goods funding model keeps the tools at zero cost for users while allowing the project to iterate on community support.

No native token has been issued and no proprietary data subscription exists.

BridgeEye: Finding the Cheapest Cross-Chain Route

The flagship tool is BridgeEye, a cross-chain bridge comparison engine connected to over 24 bridging protocols — including Across, Allbridge, Stargate, cBridge, Connext, and Multichain — as well as centralized exchange withdrawal routes from Binance, OKX, KuCoin, and Bybit.

When a user wants to transfer an asset from one chain to another, BridgeEye fetches live quotes from every supported route and presents them sorted by total cost: swap fees, bridge fees, and gas collapsed into a single number. Users can re-sort by speed or by bridge TVL (sourced from DefiLlama) to optimize for different goals. Hovering over any bridge name surfaces its audit status, TVL, and financing details — a quick due-diligence check embedded in the comparison flow itself.

A "No Token" filter isolates bridges that have not yet issued a native token, a useful screen for airdrop hunters looking for protocols that may still distribute governance tokens to early users. Including CEX routes alongside DeFi bridges acknowledges a practical reality: sometimes a centralized exchange hop is cheaper than any on-chain path.

ChainMap: Layer 2 Intelligence in One Place

ChainMap provides data dashboards for major Ethereum Layer 2 networks, including Arbitrum, Optimism, zkSync, StarkNet, Base, and Linea. For each network, ChainMap surfaces TVL, daily transaction counts, and active wallet counts alongside an ecosystem opportunity map.

The opportunity maps are designed for the kind of reconnaissance retail investors do when entering a new chain: finding yield farming pools, tracking token launches, discovering active lending markets, monitoring NFT collections, and identifying DAO governance votes. Rather than requiring users to visit multiple block explorers and protocol sites, ChainMap condenses that research into a single dashboard.

Multi-Wallet Check: Batch Address Analysis

For users managing multiple wallets — a common pattern among airdrop farmers and DeFi power users — ChainEye's Multi-Wallet Check allows batch queries across wallet addresses simultaneously, returning balances, transaction histories, and airdrop eligibility scores in one pass. Checking a list of addresses against an airdrop snapshot would otherwise require querying each address manually; Multi-Wallet Check handles that in bulk.

CEX Transfer Fees and MultiChain Gas

Two supplementary tools address the fee research that often gets overlooked until a transfer is already initiated.

CEX Transfer Fee lets users compare withdrawal and deposit costs for the same token across multiple centralized exchanges. Fees for the same asset can vary substantially from exchange to exchange, and surfacing those figures in one table before a move saves money on routine transfers.

MultiChain Gas provides historical gas price data across supported chains, helping users identify cheaper windows to submit transactions. On congested networks, timing a submission to a low-fee period can meaningfully reduce costs, and MultiChain Gas makes that timing data visible without needing to check each chain's native explorer separately.

Additional Utilities

ChainEye's Gitcoin Passport score tool enables users to query wallet-level Passport scores in batch mode, view score distributions across a set of addresses, and identify which credentials are scoring or unscored for any given wallet. A daily ETH faucet and curated RPC endpoint lists round out the utility set, covering the infrastructure basics users often need when setting up a new chain environment.

Funding and Ecosystem Position

ChainEye's reliance on public goods funding — Gitcoin quadratic rounds, Optimism's retroactive public goods mechanism, and protocol foundation grants — reflects a deliberate positioning as community infrastructure rather than a revenue-seeking product. Backed by Biteye's research community roots and validated by the ETH Shanghai 2023 Hackathon win, the project has built credibility without venture capital or token issuance.

For investors active across Ethereum's multi-chain landscape — moving assets between L2s, farming potential airdrops, comparing bridging costs, and tracking multiple wallet addresses — ChainEye consolidates the research and fee-comparison work that would otherwise require switching between many tools. Its open-source codebase means the community can audit exactly how fee data is fetched and displayed, and contribute improvements directly.
