Router Protocol
The Most Powerful Onchain Swaps
CrossTalk is a cross-chain messaging framework that enables smart contracts on different blockchains to communicate and execute operations across networks. The framework supports both stateful and stateless bridging, allowing developers to build decentralized applications that can initiate operations on one chain and execute them on another through contract-level data flow. CrossTalk provides gateway contracts pre-deployed on supported blockchains, facilitating message passing between source and destination chains for use cases including cross-chain NFTs, governance, stablecoins, and decentralized marketplaces.
deBridge
Trade everything, at lightspeed. Because DeFi doesn't wait.
deBridge Messaging Protocol enables trustless cross-chain message and data transfers between blockchain networks through a decentralized validator infrastructure. The protocol allows developers to invoke smart contracts across different chains, executing arbitrary data transfers and transaction calls alongside value transfers in unified transactions. Validators using Chainlink oracles ensure transaction integrity and relay data between chains, while economic staking mechanisms and slashing penalties secure the network against malicious behavior.
Dialect
The UX Stack for Web3
Blinks converts blockchain actions into shareable URLs that unfurl into interactive transaction interfaces across websites, social media, and applications. The system detects action URLs and renders transaction previews, allowing users to execute onchain operations without platform redirects. Blinks supports multi-step action chaining, parameter inputs, and transaction preview with wallet signature integration.
Ontology
The Trust Layer for Web3
A decentralized peer-to-peer communication protocol enabling secure message exchange, verifiable credential transmission, and presentation sharing between DID-authenticated entities through cryptographic encryption and agent-based routing architecture.
Socket Protocol
First Chain Abstraction Protocol
Socket Data Layer is an arbitrary message passing protocol enabling secure cross-chain communication. The system provides modular architecture with configurable switchboards for message verification and validation across blockchain networks.
Notifi Network
We power unrivaled notification experiences in web3
Notifi Notification Service is a unified API that sends messages across web2 and crypto-native channels including Discord, Telegram, email, SMS, and XMTP wallet messages.
Manifold
A Decentralized Frontier AI Lab
Epistula Protocol implements signed messaging standards using ed25519 cryptographic keys, enabling secure communication between entities on Bittensor and compatible networks. The protocol provides temporal caching and DDOS protection through signature validation.
Solchat
Solana Communication Protocol
Solchat is a decentralized communication protocol on the Solana blockchain that enables secure messaging and calls between wallets. It offers encrypted text, voice, and video communication with onchain message storage and integrates low-cost financial transactions.
Zano
Blockchain privacy for mass adoption
An integrated messaging platform utilizing the Matrix protocol to provide secure, decentralized communications within the Zano ecosystem. The messenger leverages Zano's privacy technologies and alias system to facilitate confidential communications between users, complementing the blockchain's financial privacy with communications privacy.
IronWeave
Own, control & instantly share data privately and securely
A secure messaging application implementing end-to-end encrypted communications on IronWeave's blockchain infrastructure. Messages remain confidential and tamper-proof with only intended recipients able to decrypt content. The system provides immutable storage with optional ephemeral or permanent data retention, compliance-ready frameworks for regulatory requirements, and full user control over message data. Communications are recorded on-chain with cryptographic verification while maintaining privacy through independent block encryption.
Solmail
Decentralized communication protocol on Solana
SolMail provides wallet-native encrypted communication on Solana, enabling users to send and receive messages using wallet addresses as identities. The protocol employs Elgamal session keys for end-to-end encryption and integrates with Solana Name Service for user-friendly addressing. Users communicate without centralized servers through direct wallet-to-wallet messaging.
Futureverse
Where the future can happen.
SYLO is a decentralized communications protocol designed for the open metaverse. The system provides off-chain communications, notifications, and data storage through The Seekers gamified node infrastructure, enabling applications to communicate across platforms.
Least Authority
Security and Privacy for All
Winden is a secure file transfer application based on the Magic Wormhole protocol. It provides end-to-end encryption, large file support, identity-less transfers, and eliminates third-party storage of files.
Offline Protocol
Powering People
Fernweh is a fully offline, end-to-end encrypted communication platform that enables secure messaging without internet connectivity. The system leverages local-first storage, offline cryptographic identity verification, and peer-to-peer message delivery through Bluetooth and BLE connections for direct communication in zero-connectivity zones or censored regions.
Staex
Instantly Connect, Secure, and Monetize Your Devices
A decentralized network layer implementing encrypted peer-to-peer tunnels between nodes, enabling secure device connectivity and data exchange without cloud dependencies. The system enforces zero-trust policies, eliminates need for firewalls, and provides verifiable data anchoring on blockchain.
