Launch secure, compliant, and user-friendly mobile and web wallets with AI-enabled engineering teams. From MPC custody to non-custodial DeFi access—built by 100% in-house experts.
In the high-stakes world of digital assets, trust is your only currency. One security slip can erase a billion-dollar reputation overnight. At Developers.Dev, we don't just write code; we engineer digital fortresses. Whether you are a Fintech unicorn integrating crypto custody or a Web3 startup building the next non-custodial super-app, our AI-enabled development teams deliver bank-grade security, seamless user experiences, and absolute regulatory compliance. Stop gambling with freelancers. Build with a partner who understands that in crypto, 'good enough' is a vulnerability.
Differentiating factors that ensure your success
We implement multi-layered security protocols including MPC (Multi-Party Computation), hardware security modules (HSM), and biometric authentication to ensure your users' assets are untouchable.
Zero freelancers. Zero risk. Our 1,000+ developers are full-time employees, rigorously vetted for technical excellence and ethical standards, ensuring your IP remains secure within our ISO 27001 certified environment.
We leverage enterprise-grade AI tools for code generation, automated testing, and security scanning, reducing development time by up to 40% without compromising on quality or precision.
Navigate the complex landscape of MiCA, SEC, and GDPR with ease. We build wallets with integrated KYC/AML modules and transaction monitoring to keep you compliant across global jurisdictions.
Crypto shouldn't feel like rocket science. Our AI-enabled designers create intuitive, friction-free interfaces that simplify seed phrases and transactions, driving higher user adoption and retention.
Whether it's Ethereum, Solana, Bitcoin, or a custom Layer-2 solution, our experts are proficient across the entire blockchain spectrum, ensuring your wallet is interoperable and future-proof.
From a proof-of-concept in weeks to a high-frequency trading wallet handling millions of requests, our scalable POD architecture grows with your user base and business needs.
Your code is your asset. Upon project completion, we transfer 100% of the intellectual property and source code to you, giving you total control and freedom from vendor lock-in.
The crypto market never sleeps, and neither do we. Our global support teams provide round-the-clock monitoring, updates, and incident response to ensure 99.99% uptime.
From consumer apps to institutional vaults
We build high-performance iOS and Android wallets that combine robust security with consumer-grade usability. Features include biometric login, QR scanning, and real-time portfolio tracking.
Eliminate the single point of failure of private keys. Our MPC solutions split keys into shares distributed across multiple devices, offering institutional-grade security for high-value assets.
Secure, cold-storage and warm-wallet solutions designed for exchanges, hedge funds, and banks. Includes multi-sig approval workflows, whitelisting, and audit trails.
Launch your branded wallet in record time. Our white-label framework provides a pre-tested, secure core that we customize with your branding and specific feature set.
Empower users to interact with dApps directly from their browser. We build secure extensions compatible with Chrome, Firefox, and Brave, similar to MetaMask but tailored to your ecosystem.
Bridge the gap between software and hardware. We develop firmware and software interfaces to integrate Ledger, Trezor, or custom hardware devices with your application.
Turn your wallet into a Web3 browser. We integrate protocols for swapping (Uniswap), lending (Aave), and staking directly within the wallet interface.
Visual-first wallets designed for the creator economy. Support for ERC-721 and ERC-1155 standards with gallery views, rarity traits, and marketplace integration.
High-throughput hot wallets for exchanges that handle thousands of transactions per second. Optimized for gas efficiency and rapid deposit/withdrawal processing.
Proactive security that learns. We integrate AI models to analyze transaction patterns in real-time, flagging suspicious activity and blocking malicious contract interactions.
Balance privacy with compliance. We integrate Know-Your-Transaction (KYT) tools and advanced biometrics to ensure user identity without compromising friction.
Break down blockchain silos. We build secure bridging mechanisms allowing users to move assets between Ethereum, Solana, BSC, and other chains seamlessly.
Embed crypto functionality into any app. We build robust APIs and SDKs that allow non-crypto businesses to offer wallet features to their users invisibly.
The future of usability. We build Account Abstraction wallets that offer social recovery, bundled transactions, and gas sponsorship for a Web2-like experience.
Enable commerce. We build merchant-focused wallets that accept crypto payments, convert to fiat instantly, and integrate with POS systems.
We use industry-leading tools to build secure, scalable solutions
Real results from our enterprise partners
Industry: Fintech / Banking
A rapidly growing European neo-bank wanted to offer crypto trading and custody to its existing user base but lacked the internal blockchain expertise and security infrastructure.
We deployed a specialized Fintech POD to build an MPC-based custodial wallet. We integrated Fireblocks for backend security and built a custom middleware to sync with their banking ledger.
Industry: Web3 / DeFi
A US-based DeFi startup aimed to simplify access to yield farming for retail investors through a mobile-first, non-custodial wallet application.
Our team built a React Native mobile wallet with Account Abstraction (ERC-4337) to enable gas-less transactions and social recovery, abstracting away the complexity of private keys.
Industry: Capital Markets
A proprietary trading firm in Singapore needed a bespoke wallet infrastructure to support high-frequency arbitrage trading across multiple centralized and decentralized exchanges.
We engineered a custom Rust-based hot wallet service hosted on AWS Nitro Enclaves, optimized for throughput and integrated directly with their trading algorithms via gRPC APIs.
