Explorers overview
Explorers are web tools designed for reading blockchain data, allowing users to look up accounts, transactions, blocks, and smart contracts. They provide a searchable user interface (UI) that indexes on-chain data, making it easy to verify activity and debug issues.
What explorers show
In TON, explorers typically display account balances, transactions, tokens, contract code and state, as well as links to related blocks and messages.
More precisely, explorers show:
- Balances and assets: Grams, jettons (FTs), and NFTs held by an address
- Transactions and messages: history, fees, phases, and traces
- Blocks and validators: block contents, masterchain and shardchain details
- Smart contracts: code, state, disassembly, and known contract type
- Analytics: top entities, volumes, gas, fees, and network health
Indexers
Indexers such as TON Center API v3 continuously read blocks from nodes, parse messages and transactions, and store them in a database optimized for queries. Explorers rely on these indexers to provide fast search, traces, higher-level events, and historical views beyond what a single node exposes by default.
Examples
TON explorer is a low-level developer-oriented explorer that displays transactions and blocks. It works on mainnet and testnet.
