Cardano's on-chain governance body — the DReps (Delegated Representatives) of the Voltaire era / CIP-1694 — live from the public Koios indexer, no key. In the Conway era ADA holders delegate their voting power to DReps, who vote on governance actions; the Cardano account reader resolves a single stake account's DRep choice, but there is no registry of the DReps themselves. This opens it. List every DRep with its registration and native-script status; look up one DRep in full — its live delegated voting power (the ADA whose vote it casts), its 500 ADA registration deposit, whether the mandate is still active and the epoch it expires; read the governance actions a DRep has voted on with each Yes / No / Abstain decision; and track the network-wide DRep population and total active voting power per epoch. The governance layer for Cardano wallets, voting tools, DRep explorers and analytics. Distinct from the Cardano account reader (per-account vote), the chain-economics reader and the native-token registry. Live from the indexer; short cache only.

Cardano native tokens, live from the public Koios API — no key, nothing cached. On Cardano every token is a "native asset" identified by a policy id plus an asset name, minted under a Plutus or native minting policy. The Cardano on-chain reader lists the tokens held by an account, but there is no token registry in the marketplace; this opens it. Browse the verified token registry — the curated tokens that have submitted off-chain metadata, with their ticker, decimals, description and logo. Look up a single token in full with its on-chain facts: the asset fingerprint, total supply, how many times it has been minted and burned, and when it was first created. And list every native asset minted under a given policy id — one policy can mint a single fungible token or a whole NFT collection. The token layer for Cardano wallets, DEXs, token explorers and analytics. Live from api.koios.rest.

Algorand Standard Assets (ASAs) — Algorand's native token standard — live from the public Algonode indexer, no key, nothing cached. Every fungible and non-fungible token on Algorand, including Circle's USDC and Tether's USDt, is an ASA. The Algorand on-chain reader looks up a single asset, but there is no ASA registry in the marketplace; this opens it. Browse the ASA space paginated, each asset with its id, name, unit, total supply and decimals. Look up a single ASA in full — its name, unit, total supply (raw and decimal-adjusted), project URL and the on-chain role addresses that govern it: the manager (can reconfigure or destroy), the reserve, the freeze address and the clawback address. And search ASAs by name to find a token (with a reminder to verify the creator, since anyone can mint an ASA with any name). The token layer for Algorand wallets, DEXs, token explorers and analytics.

The Tezos Layer-2 smart-rollup layer, live from the public TzKT indexer — no key, nothing cached. Smart rollups are Tezos's enshrined Layer-2: optimistic rollups — including Etherlink, the EVM-compatible L2 — that post state commitments back to Tezos and are secured by on-chain refutation games. The existing Tezos readers cover the base chain, the bakers and governance, but not the rollup layer; this opens it. List the smart rollups ranked by inbox level, each with its address, name, PVM kind (wasm), staker counts and commitment tallies. Look up a single rollup by address in full, with its cemented, pending and refuted commitments and refutation-game activity.
