Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- From Specification to Mainnet: We handle the full lifecycle—design, development, testing, and deployment—ensuring gas efficiency and upgradeability.
- Security as Standard: Every contract undergoes static analysis, formal verification, and peer review to mitigate risks before audit firms like
CertiKorQuantstamp. - Protocol Integration: Seamlessly connect your contracts with oracles, bridges, and decentralized storage for a fully functional dApp.
Deliver a secure, auditable, and performant smart contract suite in 4-6 weeks, reducing your technical risk and accelerating time-to-market.
Core Technical Capabilities
Our wallet plugin is engineered as a production-ready infrastructure component, delivering the security, interoperability, and performance required for high-volume NFT marketplaces.
Multi-Chain Wallet Integration
Seamless, secure connection to 20+ EVM and non-EVM chains (Ethereum, Polygon, Solana, Base) via a single SDK. We handle chain detection, RPC optimization, and network switching logic.
Secure Transaction Signing
Enterprise-grade transaction construction and signing flow. Implements EIP-712 for structured data, gas estimation optimization, and hardware wallet (Ledger/Trezor) support out-of-the-box.
NFT Portfolio Management
Real-time fetching and display of user's NFT collections across all connected chains. Includes metadata standardization, lazy minting state handling, and advanced filtering by contract or trait.
Marketplace Action SDK
Pre-built, customizable UI components for core marketplace actions: listing, bidding, buying, and batch transfers. Reduces frontend development time by 80%.
Gas Optimization Engine
Dynamic gas fee estimation with multi-layer fallbacks (on-chain oracles, mempool simulation). Features batch transaction bundling to reduce user costs by up to 40%.
Compliance & Analytics Ready
Built-in event tracking for wallet activity, transaction success/failure rates, and user journey mapping. Data is structured for easy export to compliance tools and analytics platforms.
Business Outcomes for Your Marketplace
Our Multi-Network NFT Marketplace Wallet Plugin delivers measurable improvements in user acquisition, retention, and revenue. Here’s what you can expect.
Frictionless User Onboarding
Reduce user drop-off by up to 70% with a single-click, non-custodial wallet connection that works across 15+ EVM and non-EVM chains. No seed phrase management for users.
Increased Transaction Volume
Enable seamless cross-chain NFT purchases and listings without bridging assets. Users can buy on Polygon with ETH on Arbitrum, directly increasing your marketplace's total volume.
Enhanced Security & Trust
Deploy with confidence using our battle-tested, audited smart account infrastructure. We implement MPC and passkey technology, removing private key vulnerabilities.
Faster Time-to-Market
Go live in weeks, not months. Our pre-built, white-label plugin integrates with your existing UI/UX, handling all wallet logic, RPC management, and gas sponsorship.
Reduced Operational Cost
Eliminate the need to build and maintain separate wallet integrations for each blockchain. Our unified API and managed infrastructure cut engineering overhead by over 60%.
Superior User Retention
Leverage embedded wallet analytics and session management to understand user behavior. Implement features like gasless transactions and one-touch re-login to boost stickiness.

Our Integration & Delivery Process
A structured, transparent process designed for technical teams. We deliver production-ready wallet plugin integrations in weeks, not months, with zero surprises.
Discovery & Architecture Review
We conduct a deep-dive technical session to audit your existing marketplace stack, define integration touchpoints, and finalize a multi-network strategy (EVM, Solana, etc.).
Secure Plugin Development
Our engineers build the wallet connector using battle-tested libraries (Ethers.js, Web3.js, Solana Web3) with a focus on security, state management, and seamless UX across all target chains.
Multi-Chain Testing & QA
Rigorous testing across all supported networks (Mainnet & Testnet) for transaction signing, network switching, balance polling, and error handling to ensure flawless production performance.
Staging Deployment & Review
We deploy the plugin to your staging environment for internal team review, providing comprehensive documentation and integration guides for your developers.
Production Launch Support
We manage the production deployment, monitor initial user adoption, and provide immediate technical support to ensure a smooth public launch and user onboarding.
Ongoing Maintenance & Updates
Post-launch, we offer maintenance packages for wallet SDK updates, new chain integrations, and performance optimizations based on real user analytics.

Frequently Asked Questions
Common questions from CTOs and product leads about integrating a secure, multi-chain NFT wallet plugin.
A standard multi-network NFT wallet plugin with core features (connect, view, transfer) takes 2-4 weeks from kickoff to production deployment. Complex integrations, such as adding batch operations, custom chain support, or advanced security modules, can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
