Infrastructure & Oracles
Nodes, indexers, hosted APIs, layer 2 and scaling protocols, bridges and cross-chain infrastructure, decentralized storage and oracle networks serving Cardano.
Ogmios
Ogmios is a lightweight bridge that exposes the Cardano node's mini-protocols over JSON-RPC and WebSockets, so applications can sync the chain and submit transactions without speaking the binary protocol.
Midnight
Midnight is a privacy-focused partner chain in the Cardano ecosystem, offering programmable data protection and a predictable cost model for applications that need selective disclosure.
Charli3
Charli3 is a decentralized oracle network for Cardano that publishes price and data feeds to smart contracts, with both push and pull delivery and a staking model around its C3 token.
Blockfrost
Blockfrost is a hosted Cardano API that gives developers instant, scalable access to chain data and transaction submission without running their own node, including a free tier.
Nexus
Nexus, from A.D. Labs, is a managed multi-chain data and transaction API covering Cardano, Midnight and Bitcoin, with multi-provider failover and an OpenAPI 3.1 specification.
Blink Labs
Blink Labs builds open-source nodes, protocol libraries, indexers and data services for UTxO blockchains, and co-operates the Demeter managed Cardano API service with TxPipe.
Demeter
Demeter is a managed platform for Cardano dApp infrastructure, giving teams hosted nodes, indexers and APIs they can scale without running servers themselves.
TxPipe
TxPipe builds open-source Cardano infrastructure, including the Oura event stream, the Pallas libraries, the Dolos data node and the Demeter hosting platform.
dcSpark
dcSpark builds blockchain products focused on interoperability and composability, and maintains Cardano developer libraries and the Milkomeda sidechain work.
Tangocrypto
Tangocrypto offers Cardano APIs, webhooks and no-code tools so teams can read chain data and react to on-chain events without running infrastructure.
Mithril
Mithril is a stake-based threshold multi-signature protocol that produces certified snapshots of Cardano state, letting nodes and light clients bootstrap without replaying the whole chain.
cardano-db-sync
cardano-db-sync follows the Cardano chain and writes blocks and transactions into PostgreSQL, providing the relational backend most Cardano explorers and analytics tools rely on.
cardano-rosetta-java
cardano-rosetta-java is a lightweight Java implementation of the Mesh (formerly Rosetta) integration API for Cardano, built on Yaci Store for a smaller resource footprint.
Iagon
Iagon is a decentralized cloud platform on Cardano that pools unused storage and compute from node operators and rents it to users.
Orcfax
Orcfax is a decentralized oracle for Cardano built around independently verifiable, permanently archived data, so smart-contract inputs can be audited after the fact.
cardano.delivery
cardano.delivery sends signed HTTP webhooks for Cardano mainnet events such as transactions, blocks, delegations and epoch changes, with no infrastructure to run.
cardano-node
cardano-node is the core software that participates in the Cardano network, produced and maintained under Intersect.
cardano-node-api
cardano-node-api exposes a multi-protocol API in front of a local Cardano node so applications can query and submit without implementing the node protocols.
Milkomeda
Milkomeda is a sidechain and rollup project that brings EVM smart contracts to Cardano, so Solidity applications can be deployed against Cardano liquidity.
Koios
Koios is a distributed, community-run API layer for Cardano, giving applications elastic query access to chain data across independent provider instances.
Hydra Head Protocol
Hydra is Cardano's layer 2 head protocol, letting a small group of participants transact off-chain at high speed and settle back to the main chain.
ODATANO
ODATANO exposes Cardano chain data over the standard OData V4 protocol, so enterprise systems such as SAP landscapes can query it directly.
Dolos
Dolos is a TxPipe data node that keeps a trimmed copy of Cardano state, giving applications node-grade access without running a full node.
Oura
Oura tails the Cardano blockchain and streams on-chain events to sinks such as Kafka, webhooks and databases for real-time pipelines.
CardanoBI
CardanoBI is an open-source business intelligence API layer for Cardano, exposing aggregated chain data for reporting and analysis.
UTxO RPC
UTxO RPC is a standard gRPC interface for UTxO blockchains, giving Cardano tools a common way to talk to nodes and data providers.
Scrolls
Scrolls builds and maintains a read-optimized cache of Cardano on-chain entities so applications can query current state quickly.
Carp
Carp is dcSpark's modular Cardano indexer with a PostgreSQL backend, offered as a lighter-weight alternative to cardano-db-sync.
Kupo
Kupo is a fast, lightweight and configurable chain indexer for Cardano that tracks only the patterns an application cares about.
Yaci Store
Yaci Store is a modular Cardano data store built on the Yaci library, letting teams index only the chain components they need.
gOuroboros
gOuroboros is a Go implementation of the Cardano Ouroboros family of network protocols, used to build Go-based node tooling.
Cardano on BigQuery
Cardano on BigQuery, from Blockchain Applied, makes the full Cardano chain queryable with standard SQL in Google BigQuery.
Wanchain
Wanchain is a cross-chain interoperability network whose bridges connect Cardano to other blockchains for asset transfers.
Argus
Argus is a .NET indexing framework that turns Cardano block data into structured, queryable records for C# applications.
cf-ledger-sync
cf-ledger-sync is an open-source Java application from the Cardano Foundation for accessing indexed Cardano ledger data.
Rosen Bridge
Rosen Bridge is an open-source protocol for moving assets across chains, including transfers between Cardano and Ergo.

How do I know a project is safe?
Look for a public team, a published audit, open-source code, and a token policy ID you can verify on a Cardano explorer. Never connect a wallet to a site you reached from an unsolicited link.
