Cosmos & Polkadot Multi-Chain Wallet Hub
We build secure, interoperable dashboards for Cosmos (Keplr, Leap) and Polkadot (Polkadot.js, Talisman) ecosystems. Manage cross-IBC/XCMP connections, assets, and chain-specific features in one unified interface.

overview
CORE INFRASTRUCTURE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from token standards to complex DeFi logic.
- Custom Token Standards:
ERC-20,ERC-721,ERC-1155, and bespoke implementations with custom minting, vesting, and governance logic. - DeFi & dApp Logic: Automated market makers (AMMs), staking pools, lending protocols, and multi-signature wallets.
- Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol sustainability.
Our process delivers a fully tested, deployable contract suite in 2-4 weeks, giving you a secure foundation to build upon without the typical 6-month development cycle.

Frequently Asked Questions
Common questions from CTOs and technical leads about our Cosmos & Polkadot wallet hub development services.
Standard deployments take 8-12 weeks from kickoff to mainnet launch. This includes 2 weeks for architecture design, 4-6 weeks for core development and integration, and 2 weeks for security audits and testing. Complex features like custom governance modules or advanced key management can extend the timeline, which we scope and quote for upfront.
