DeFi App Development
We create secure, scalable applications for lending, staking, and trading, aligned with blockchain standards.
Solicy develops secure, high-performance blockchain APIs that connect decentralized systems to practical applications. We support digital wallets, trading platforms, NFT marketplaces, and other Web3 products. Each API is built for live interaction with smart contracts, tokens, blockchain transactions, and metadata, tailored to your system architecture, supported chain, and performance needs.
Each project follows a structured process to create reliable and secure blockchain APIs that align with your product’s architecture, use cases, and target networks. From planning to post-launch support, the goal is to deliver an API that fits smoothly into your system and supports real-world usage.
The process starts with a focused discussion of what your API needs to do and how it supports your product goals. Solicy helps identify the right blockchain network, outline user flows, and define the required functionality.
Once the requirements are clear, we design the API structure based on how your application will interact with the blockchain. This includes defining data formats, access rules, transaction flow, and internal security layers.
Our developers write the API logic using tools like Node.js, Python, or Go. We build connections to smart contracts, tokens, and blockchain data while testing each part in a controlled environment before going live.
We apply strict security practices during development. The API includes authentication, input validation, encryption, and access management. Both automated tools and manual reviews are used to test functionality under real conditions.
After testing is complete, the API is deployed to a stable and scalable environment suited to your infrastructure. Each project includes technical documentation with clear request examples, version notes, and authentication details to support smooth integration.
After launch, Solicy remains involved to monitor performance, apply updates, and adapt the API to network changes. Built-in tracking tools allow your team to identify issues quickly and respond as usage grows.
Solicy develops APIs for many types of blockchain applications, including finance tools, NFT platforms, identity systems, and digital wallets. Each solution is planned based on how your product works and what it needs to achieve.
Each API includes encryption, input checks, access control, and request limits. During development, the code is reviewed and tested to reduce common risks and prevent misuse.
APIs are tested to confirm that they work consistently with high traffic and frequent requests. This makes them a good fit for platforms that process large volumes of data or user activity.
The API structure follows the logic of your product. We design with your users in mind, not just technical rules, so the result fits naturally into your system and can grow with it.
Our work continues after delivery. The same team that develops your API remains available to help with updates, track performance, and support future improvements.

Our online platform and app were developed and managed by Solicy. Their help pleased our internal team; they were very proactive, approachable, and easy to deal with.
We serve a diverse range of industries — not just the ones listed below. If your sector isn’t mentioned, there’s a good chance we’ve worked in it too Let’s talk.
For secure, efficient, and scalable server-side processing.
Blockchain APIs allow your application to interact with existing blockchain networks, for example, by calling smart contracts or accessing token data. Full blockchain development typically involves building smart contracts, custom tokens, or launching a new blockchain layer. APIs offer a more focused and integration-friendly approach.
APIs are designed to work alongside your current systems, whether you’re adding Web3 features to a web app, mobile app, or internal tool. Integration points are planned early to ensure smooth data flow and minimal disruption.
Finance, gaming, digital identity, logistics, and NFT platforms are common users of blockchain APIs. These industries rely on APIs to add features like wallet access, KYC checks, token transfers, and NFT minting without building everything from scratch.
Security features include encryption, access control, request validation, and activity logging. Each API is tested manually and automatically to prevent unauthorized use and reduce exposure to risks like replay attacks or input tampering.
Blockchain APIs can interact directly with smart contracts to mint NFTs, issue tokens, or read contract data. This allows your application to use on-chain logic without forcing users to interact with blockchain interfaces directly.
Most blockchain API projects are completed within 3 to 8 weeks. Timelines depend on the complexity of your use case, the number of endpoints, and the chains involved.
