Encrypted Messaging Protocol SDK

A developer library for integrating end-to-end encrypted, decentralized messaging with on-chain settlement or proof-of-message capabilities, ensuring metadata and content privacy.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contract development for DeFi, NFTs, and enterprise applications.

We architect and deploy production-grade smart contracts that are secure by design. Our process includes formal verification and multiple audit stages to protect your assets and users.

Deliver a fully audited, gas-optimized contract suite in 4-6 weeks, from initial spec to mainnet deployment.

  • Custom Logic: Build for ERC-20, ERC-721, ERC-1155, staking, governance, and complex DeFi primitives.
  • Security First: Development follows OpenZeppelin standards and undergoes peer review + third-party audit.
  • Full Lifecycle: We handle deployment, upgradeability planning (TransparentProxy/UUPS), and monitoring.

BUILT FOR PRODUCTION

Core Technical Capabilities

Our Encrypted Messaging Protocol SDK is engineered for enterprise-grade security and developer velocity. We deliver battle-tested cryptographic primitives, not just theoretical concepts.

02

Multi-Protocol Wallet Integration

Seamless integration with EVM (MetaMask, WalletConnect), Solana (Phantom), and Cosmos (Keplr) wallets for cryptographic signing and identity verification. Supports EIP-712 structured data signing.

Frequently Asked Questions

Get clear answers on our development process, security, and support for your encrypted messaging protocol.

A standard SDK with core E2E encryption, group chat, and wallet integration takes 4-6 weeks from kickoff to production-ready delivery. Complex features like decentralized identity (DID) attestations or cross-chain messaging can extend this to 8-12 weeks. We provide a detailed sprint plan within the first week of engagement.
