Read Tezos's on-chain key-value storage (bigmaps) live from the public TzKT indexer — no key. A bigmap is Tezos's lazily-deserialised on-chain map: the data structure smart contracts use for the big stuff — token ledgers (who owns what), NFT ownership, allowances and metadata. The Tezos contract explorer lists contracts and their interface, but it cannot browse the bigmaps themselves, read a bigmap's typed key/value schema, or page through its live key-value entries. This opens that. Browse and rank the bigmaps by size with their pointer, owning contract, path (e.g. "ledger"), tags and total/active key counts; read one bigmap's detail and its typed key/value schema (what shape each row's key and value take, e.g. an address-to-nat token ledger); and page through a bigmap's live key-value entries — the actual on-chain data, such as the address-to-balance rows of a token ledger or the owner rows of an NFT collection. The storage / data layer for Tezos explorers, indexers, token dashboards and analytics. Distinct from the Tezos on-chain reader (account state), the smart-contract explorer, the FA-token registry and the .tez naming reader. Live from the indexer; short cache only.

Browse Tezos smart contracts live from the public TzKT indexer — no key. On Tezos a smart contract is an originated KT1 account with Michelson code, on-chain storage and named entrypoints. The Tezos on-chain reader resolves a single address's account state, but it cannot browse the contract universe, rank contracts by balance or activity, read a contract's callable entrypoints, or read its code identity. This opens that. Browse and rank the deployed smart contracts with their KT1 address, XTZ balance, creator, lifetime transaction count and token activity; read one contract in full — its balance, creator, code/type hash (contracts sharing a code hash run identical Michelson) and current delegate; and read the named entrypoints a contract exposes — its callable interface, each method with its parameter schema. The contract layer for Tezos explorers, dApp dashboards, wallets and analytics. Distinct from the Tezos on-chain reader (per-address account state), the self-amending governance reader, the baker reader, the FA-token registry and the .tez naming reader. Live from the indexer; short cache only.

Read the Tezos Domains naming service live from the public TzKT indexer — no key. Tezos Domains maps human-readable .tez names to Tezos addresses, the way ENS maps .eth names on Ethereum. None of the Tezos on-chain, governance, baker, smart-rollup or FA-token readers expose the naming layer; this opens it. Browse the most recently active .tez domains with their owner address, the address they point to, registration level and expiry; forward-resolve a .tez name to the address that owns it (how a wallet turns "alice.tez" into a tz1 address); and reverse-resolve any Tezos address to the .tez names registered to it (an address can own several). The identity / naming layer for Tezos wallets, explorers, payment UX and analytics. Distinct from the Tezos on-chain reader, the self-amending governance reader, the baker reader, the smart-rollup reader and the FA-token registry. Live from the indexer; short cache only.

Browse the Tezos token universe live from the public TzKT indexer — no key. Tezos tokens are FA1.2 (fungible) and FA2 (fungible or NFT) contracts. The Tezos on-chain reader returns the token balances a single address holds, but it cannot browse the token universe, rank tokens by holders, list who holds a token, or trace a token's transfers. This opens that. Discover and rank FA tokens and NFT collections with their TzKT token id, contract, standard, name, symbol, decimals, holder and transfer counts, decimal-adjusted total supply and — for NFTs — their resolved artwork image; list the holders of any token with their decoded balances, largest first; and trace a token's recent transfers with sender, receiver, decimal-adjusted amount and time (a mint shows no sender, a burn no receiver). The discovery, NFT and distribution layer for Tezos wallets, token explorers, NFT marketplaces and analytics. Distinct from the Tezos on-chain reader (per-address token balances), the self-amending governance reader, the baker/validator reader and the smart-rollup reader. Live from the indexer; short cache only.
