Codex Scan
Multichain block explorer with decoded transactions, contracts, tokens, and wallets.
Overview
Codex Scan is a free block explorer from Codex that covers Ethereum, Solana, and a long list of EVM chains, including Base, Arbitrum, Optimism, Polygon, Avalanche, Monad, and HyperEVM. It reads chain data from RPC nodes and adds prices, DEX trades, holders, and labels from the Codex API.
Transactions are decoded on the server into method calls, event logs, token transfers, and SVM instructions, and token contracts show price, holders, and trades on the same page. Each network has a home page with latest blocks and transactions, native token price, DEX volume, and top and new tokens, and search works across every network at once.
Pages follow the EIP-3091 pattern (scan.codex.io/<network>/tx/<hash>), so wallets and tools can link to them directly. Alongside the chains shown here, Codex Scan also covers Polygon zkEVM, Metis, Mode, Cronos, Astar, X Layer, Robinhood Chain, Ink, Zora, ApeChain, Katana, and Story.
