Polkadot Parachain Wallet SDK

Unified account system for Polkadot, Kusama, and connected parachains. Supports native Substrate accounts, Ethereum-compatible (EVM) addresses via Frontier, and seamless key derivation for a single user identity across the ecosystem.

Broadcast, track, and decode transactions with sub-second latency. Built-in fee estimation, nonce management, and lifecycle hooks (pending, in-block, finalized) ensure reliable user experience.

Private key management with hardware wallet (Ledger) integration and secure enclave support. All cryptographic operations use audited libraries, following OWASP and Web3 security best practices.

Native support for XCM (Cross-Consensus Messaging) transfers, token balances, and staking rewards across parachains. Pre-built UI components for asset bridging and portfolio views.

Pre-integrated modules for nominating validators, claiming rewards, and participating in on-chain governance (referenda, council voting). Reduces development time for DeFi and DAO applications.

Fully typed SDK with React Native bindings for iOS and Android. Includes comprehensive documentation, example apps, and dedicated support for integration. Get to market in weeks, not months.

Deploy a fully functional, secure wallet in under 2 weeks. Our SDK includes pre-built modules for account management, transaction signing, and cross-chain messaging, eliminating months of development time.

Built with OpenZeppelin security patterns and audited by leading Web3 security firms. Our SDK enforces best practices for key management, transaction validation, and regulatory compliance (Travel Rule, AML).

Provide a native user experience for XCM transfers, staking, and governance across the Polkadot ecosystem. Our SDK handles complex state synchronization and fee management automatically.

Architected to handle high-throughput DeFi and NFT applications. Features include non-custodial multi-sig, batch transactions, and optimized RPC endpoints with 99.9% uptime SLA.

Go beyond generic solutions. We provide custom pallet integration, ensuring your wallet interacts flawlessly with your parachain's unique runtime logic and custom assets.

We conduct a deep-dive workshop to define your target parachains, required XCM capabilities, and user journey. Deliverables include a technical specification and a detailed project roadmap.

Our engineers build the core wallet SDK modules—key management, transaction signing, and balance queries—using Polkadot.js and our proprietary security libraries. Code is written in TypeScript for maximum developer ergonomics.

We implement cross-chain messaging (XCM) for asset transfers and integrate with your specified parachains (e.g., Acala, Moonbeam). This phase includes rigorous testing on testnets like Rococo.

The completed SDK undergoes an internal security review followed by a formal audit from a partner firm. We deliver a comprehensive audit report and implement all critical fixes.

We provide complete API documentation, integration guides, and a reference implementation. Your team receives dedicated training sessions and access to our technical support channel.

We assist with the mainnet deployment and provide 6 months of included support with a 99.9% uptime SLA for our hosted components, ensuring a smooth production launch.
