your guide to privacy in web3

Cupcake is an air-gapped wallet using live QR codes. It works similarly to a hardware wallet, separating the private keys from the main wallet app and becoming a dedicated transaction signer.

A cryptography lab focused on human-first applications of signed data.

Curvy is the privacy infrastructure layer for on-chain payments - built for the wallets, applications, and AI agents. On the surface, users get human-readable usernames as a frictionless entry point for receiving crypto. Under the hood, every payment is automatically routed through programmable smart contracts using ZK proofs: a fresh address is generated per transaction, funds are shielded from balance exposure and transaction graph analysis, and time-based correlation attacks are prevented by design. The result is end-to-end cross-chain privacy with a user experience identical to a normal wallet transfer. What makes Curvy distinct is the combination of three properties no existing solution delivers together: invisible UX (privacy requires no action from the user or the agent), embedded compliance and adjustable infrastructure (wallets, DeFi apps, payment platforms, and AI agent frameworks integrate via SDK in minutes).

Cyclone is a protocol that applies zkSNARKs to enable transactional privacy by breaking the on-chain link between depositor and recipient addresses.

Darklake is a privacy-first DEX using ZK proofs to prevent MEV before it starts. Darklake’s zkAMM encrypts trade size, direction, and slippage to ensure trader intent remains private. This prevents malicious actors from extracting value through front-running, sandwiching, or other forms of MEV. Unlike other systems that mitigate the negative effects of MEV through retroactive protection or L2 wrappers, Darklake builds native defense directly into its execution logic with built-in encryption at the protocol level.

Dawnswap is a decentralized open-source non-custodial peer-to-peer exchange platform built with Monero and Tor at its core. It is based on the existing open-source codebase of the Haveno project which aims to support the rapidly growing Monero community and crypto in general all over the world. Making it easier for everyone to trade crypto and fiat currencies without middlemen and trusting third parties.
