System Integrations

As a leading software development company, we’re experts at building secure, complex integrations between multiple systems. An integration can enable existing, new, or legacy systems to handle deposits, transfers, lending, the transformation of one digital asset into another, and more. We have experience building custom integrations for:
  • Mobile apps. Build integrations with wallets or other platforms for payment processors, banks, exchange integrations, and other digital fintech systems.
  • Live wallets. One wallet with multiple addresses, which is constantly updated using a system where all operations are sent with regular APIs. This allows other systems to interact with the live wallet the same way they would with each other.

Value Tracking

When a mobile app offers multiple different currency options and the ability for users to retrieve or exchange funds, the system needs to be able to track and balance the liquid funds being stored internally in order for the customer to complete transactions successfully. A value tracking system defines the amount held safely offline in cold storage, and in what currency.

Exchange Integrations

Our experience allows us to build exchange integrations for banks and financial institutions that allow the exchange of one digital coin for another, or the ability to trade fiat money for digital assets. We’re also able to build integrations between other systems and an existing exchange integration – such as Changelly.

Mobile Apps/Platforms

Our mobile app development experience allows us to build apps that depend on digital assets, such as enabling mobile payment from peer-to-peer cryptocurrencies or providing unique and value-added features only to users who hold a particular asset.

Wallet Development or Integration

Build a wallet that meets your company’s unique needs. We’re able to work with businesses that have built a custom system and require a wallet to go with it. By creating an open-source model, we’re able to adjust it to the coin you need, which is especially valuable for someone developing a new currency. We’re also able to develop desktop apps to accompany a wallet. If you already have a wallet, we’re able to build integrations between existing wallets and any other system. A wrapper allows users and other systems to make and check transactions in an extremely secure way.

Secure cryptocurrency software delivery

AccelOne is strongly committed to creating software that’s both highly functional and highly secure. We work with third-party partners that are leaders in the cybersecurity market, both in the US and in Argentina. We take precautions to both protect our clients from an attack on the internal workings of their app, as well as to ensure that users take proper security safeguards, which include:

  • Highly-secure hosting measures, which apply key security standards into the software itself
  • Secure, encrypted communication channels
  • VPN software to secure resources
  • A cross-team code review process
  • Code quality scanning using the SonarQube continuous inspection concept
  • Code scanning with Snyk for enhanced security

Ethereum Experts

The Ethereum blockchain and computer network not only supports its native currency, Ether, but also serves as a basis for many other successful cryptocurrencies, including Polygon (MATIC), Decentraland (MANA), Chainlink (LINK), Axie Infinity (AXS) and more. Ethereum is also the most popular platform for the creation of dApps, NFTs, smart contracts, and DeFi projects. AccelOne’s crypto developers are experts in building with Ethereum, allowing you to integrate with and challenge the most innovative and popular crypto projects right from the get-go.

NFT and Tokenization Platform Development

NFTs, or non-fungible tokens, refer to a piece of media (usually an image, but audio and video NFTs also exist) that is linked to an address on the blockchain, becoming a token with a completely unique ID. The technology forms the basis of digital collectibles and artworks as well as ownership of tradeable items in the metaverse.

Decentralized Applications

Decentralized Applications, also known as Distributed Applications, or DApps are apps that run on multiple computers (nodes) of a blockchain network. Not only does this protect the application from hardware failures and outside tampering, but it also allows for the execution of smart contracts, where computers on the network can validate information to automatically execute payments for services, and conduct DeFi applications such as lending and borrowing.

Cryptocurrency Software Development Process

With cryptocurrency software development, the nature of the project will depend on the scope of features and the proposed functions of your cryptocurrency. We follow an organized process to make sure the product aligns with your goals and that the resulting cryptocurrency will have all the desired functionality.

  1. Define goals and assign roles: In collaboration with your company, we will explore and confirm your business needs and how the product will address them. At this stage, we will advise, raise any potential issues in advance, select the best team for you and provide you with a roadmap and communication platform.
  2. Research and Design: Our team researches and plans out how the product will fulfill its goals and what is necessary to include. Elements such as UI will begin to form at this stage. We also design and test prototypes to demonstrate how it will work, and take on feedback from the client.
  3. Development: Assimilating what was learned in the R&D phase, we develop your cryptocurrency product, building up to full functionality, with a concurrent QA process to check for any bugs or issues.
  4. Testing: Our rigorous testing process ensures that your crypto product will be stable and work as intended before it goes live.
  5. Deployment: The launch of software is carried out by our experts in collaboration with your organization’s staff to ensure a smooth deployment.
  6. Monitoring and maintenance: Clients enjoy our ongoing long-term support in maintaining the cryptocurrency, conducting security checks, and troubleshooting bugs that arise after launch.
