Zera Labs

DeFi, Consumer Apps, Undefined

A privacy-and-cryptography dashboard delivering an improvement to the wallet extension experience for Solana. It complements on-chain security by protecting the internet side of Web3, ie the network layer, headers, and connections, so your packets are locked down while balances, prices, and activity stream in near real time. The network plane is hardened by default, not an afterthought. Real-time price streaming with 5s reconnect backoff keeps the UI effectively “always-fresh,” outperforming standard extension wallets that poll slowly. Anyone can replicate the stack: bring your own API credits, deploy the same Workers API, and get the same performance.

Zera - Privacy Made Simple.

DeFi, Infrastructure

Privacy on Solana is too complex. Current solutions require 50+ lines of setup code and confusing APIs, so less than 1% of Solana apps use privacy. Zera is a developer-first privacy SDK that makes private transactions simple. With a clean API, developers can implement private SOL and SPL token transfers in just a few lines:

ZeroDelta

DeFi, Stablecoins

Tokenizing arbitrage and market-making strategies into a yield-bearing stablecoin. ZeroDelta transforms professional trading strategies — like cross-exchange arbitrage, funding-rate arbitrage, and market-making — into on-chain vaults accessible to everyone. These delta-neutral strategies, normally requiring advanced infrastructure and execution, are tokenized and packaged into a yield-bearing stablecoin. By bringing high-frequency trading and arbitrage profits on-chain, ZeroDelta captures value that was once limited to private firms and redistributes it to the community through transparent, risk-managed yield.

zerolync

Consumer Apps, Infrastructure

ZeroLync is a universal wallet solution that eliminates the need for multiple wallets across different blockchains

Zeus Labs

DeFi, Consumer Apps, Infrastructure

Build, Backtest, and Deploy on-chain strategies directly on Zeus Labs infrastructure (VPS + gRPC). Become a quant with our no-code builder & AI indexer agent. - No-Code Visual Strategy Builder - AI-Powered Research & Insights - Unified Performance Dashboard - One-Click Deployment & Management ----- One Platform, Endless Strategies. A no-code drag & drop UI to create complex logic with triggers, conditions, and actions powered by Zeus Node gRPC.

ZK Coprocessor Bridge

Infrastructure, Undefined

ZK Coprocessor for Solana — a cross-chain bridge enabling private ZK computations on Aztec* via Ethereum and Wormhole, with replay-safe finality. * Aztec — private ZK L2 on Ethereum. “Solana's speed × Ethereum's security × Aztec's privacy” Extending Solana with a cross-chain ZK layer linking its fast execution to Ethereum’s mature ZK ecosystem and liquidity. Architecture: Solana ⇄ Wormhole ⇄ Ethereum ⇄ Aztec (ZK proofs) ✅ End-to-end tested on testnets, with formal proofs in Research Paper_1*. Combined with my prior ZK research*, this work may help inform the Solana Foundation’s ZK roadmap. Paper_2* * Research papers 🔬 in Additional. Market & Viability: Solana Lending TVL ≈ $4.2 B; EVM-ZK bridged TVL ≈ $3.8 B (TVL: DefiLlama) Integrating Aztec may attract EVM-ZK capital—capturing 13.5%* (early adopters model; Rogers, 2003) adds ≈ $0.5 B, a 12% growth to Solana’s Lending market. A planned ZK Coprocessor SDK could generate ≈ $2.7 M ARR.(base model of 3 estimated models) Biz Report*

zk-IoT

RWAs, Infrastructure, Undefined

ZK for IoT – Protect Privacy while Proving Compliance Generate zero-knowledge proofs from sensor readings and verify them on Solana with low fees and low latency. Upon successful verification, payments settle automatically under agreed terms. Maintain full privacy—no raw data exposed—while recording audit-ready verification hashes on-chain.

ZKMail

Consumer Apps, Infrastructure

Build a decentralized email/search platform on Solana, using zero-knowledge proofs (ZKP). Student client (browser/app) scans for malicious patterns locally. If a malicious activity is detected, a ZKP is generated proving “malicious activity occurred” (with minimal metadata such as event type/time)—without revealing the full message/search content. This ZKP is submitted to a Solana smart contract, which authorities can monitor via a dashboard. If benign, nothing is sent; authorities get no access to student history or messages.

ZK-Mail-Guardian

DeFi, Consumer Apps, Undefined

Zero-Knowledge Email Threat Detection with Blockchain Verification A decentralized email security system that analyzes emails for phishing, spam, and malware threats, then submits cryptographic proofs to the Solana blockchain for transparent, tamper-proof reputation tracking.

ZkVote

Infrastructure

Our project is called ZkVote , a decentralized on-chain voting platform built on the Solana blockchain. It allows verified users or organizations to create polls, and only eligible voters can participate. Every vote is recorded securely on-chain, making the system tamper-proof, transparent, and verifiable, while still keeping voter privacy. Our goal is to bring digital trust and transparency to online voting through Web3 technology, creating a system that’s fair, secure, and easy to use for everyone.

ZoneIn

DeFi, Consumer Apps, Undefined

Solana's first Agentic Trading OS. Using AI to help users optimize their portfolio, making better trading decision and soon to setup their own autonomous trading agents.

ZPEi

Consumer Apps

ZPEi is a revolutionary token ecosystem on Solana that empowers brands to own direct relationships with their communities, rewarding opt-in data sharing with custom brand coins redeemable for real experiences, merchandise, or even cash via debit cards and cross-brand swaps.

ZYPHER

DeFi, RWAs, Stablecoins

Zypher is the intuitive web dashboard empowering Solana builders and DeFi pioneers to forge unbreakable positions with $ZYP, the delta-neutral stablecoin backed by tokenized RWAs. Dive into encrypted minting (150% overcollateralized for ironclad security), real-time AI-agent hedging powered by PyTorch models, and ZK-proof prediction markets that settle risks in sub-second finality; all shielded by Poseidon hashes and MPC simulations. Whether you're manually overriding hedges on volatile yields or polling Pyth oracles for tamper-proof insights, Zypher turns cypherpunk ideals into actionable alpha. Connect your Phantom wallet, mint your first $ZYP, and claim your edge in the $50B stable revolution; built for the Colosseum, scaled for Solana.

Zypp Protocol

DeFi, Consumer Apps, Infrastructure

Zypp Protocol is the offline-first payment layer for Solana, enabling P2P transfers of tokens, NFTs, and files without the internet.
