Papyrus
Project Links
Description
Papyrus is a Starknet full-node implementation written in Rust. It allows users to run their own infrastructure for interacting with the Starknet network while maintaining decentralization.Category: Node Software
Stone Prover
Project Links
Description
Stone Prover is the STARK-proof generation system that powers StarkWare's products. The system generates cryptographic proofs that verify computational integrity while maintaining high performance.Category: Developer Tooling
Stwo Prover
Project Links
Description
Stwo Prover is a next-generation STARK prover that implements the Circle STARK protocol. It processes blockchain transactions with efficiency and lower costs.Category: Developer Tooling
StarkEx
Project Links
Description
StarkEx is a Layer 2 scaling engine that provides high throughput and low gas costs for applications such as NFT minting, trading, spot trading, and derivatives.Category: Cross-chain Infrastructure
Ztarknet
Project Links
Description
Ztarknet is a Starknet-style Layer 2 that settles to Zcash L1 using Circle STARK proofs verified through a Transparent Zcash Extension (TZE). The sequencer runs Madara and executes Cairo programs, with state transitions proved by Stwo and anchored to Zcash consensus via a single built-in TZE verifier rule. This design enables general-purpose smart contracts and confidential DeFi to inherit Zcash's base-layer privacy without a multisig bridge.Category: L2
STRK20
Description
STRK20 is a privacy framework that brings shielded balances and private transfers to ERC-20 assets on Starknet. It operates at the protocol level and is accessed from the user's wallet, letting holders shield a balance, transact privately, and unshield in one action. The framework shares a viewing key with an independent auditor to enable scoped, compliant disclosure when legally required.Category: Developer Tooling
StrkBTC Bridge
Project Links
Description
strkbtc.io is a bridge that moves native BTC into Starknet, minting strkBTC backed one-to-one by Bitcoin locked on the Bitcoin network. Built by StarkWare and powered by Atomiq, it lets Bitcoin holders bring BTC onto Starknet to access DeFi and optional privacy. The bridge runs a federated model operated by the strkBTC Federation, with a roadmap toward a trust-minimized architecture.Category: Bridge
