What are Blockchain Development Agencies?

Blockchain development companies are independent firms that can build blockchain-based applications for any business. If a business wants to build a project on the blockchain but doesn’t have the expertise to do it in-house, they can hire a blockchain development firm to bring the project to life.

They typically have dozens of blockchain software developers on staff. These developers may have specialties ranging from DeFi coins to NFT launches to crypto exchange development. Also, they usually operate on a subset of public blockchains, such as Ethereum, Binance Smart Chain, or Avalanche.

Some companies can also build blockchains from scratch, which can be useful for enterprise-scale businesses that want a blockchain to manage their own operations.

What Services Do Blockchain Development Firms Offer?

Some blockchain development firms will work on any blockchain-related projects. Others specialize in specific types of decentralized apps. Some of the most common services that these firms offer include:

• New token or cryptocurrency development
• NFT launches
• Play-to-earn crypto game development
• Crypto wallet design
• Crypto exchange development
• Smart contract development
• NFT marketplace design
• DeFi app development

Many of these firms also offer consulting services on an as-needed basis. This enables companies that are largely capable of building blockchain-based apps on their own to get help when they need it. It also ensures that companies that rely on a blockchain development firm can get ongoing support for their projects long after deployment.

The firms are very good at turning ideas into decentralized apps. However, companies need to approach these firms with a specific project or idea in mind. These companies can refine ideas and explain what’s possible, but they won’t create a business strategy from scratch.

How We Rank the Best Blockchain Development Companies

Choosing a blockchain development company is a big decision. Many businesses end up spending tens of thousands of dollars to bring a decentralized project to life. In addition, a successful blockchain app launch is often seen as a reflection on a business itself. With that in mind, here are some of the key factors we consider when choosing the best company for blockchain development.

Services Offered

Most blockchain development companies offer a wide variety of services. Businesses can go to a single company for everything from launching a crypto exchange to building the next hot emerging cryptocurrency. Having a wide variety of services is important for businesses because it gives them options.

If a business successfully completes a blockchain project with a company and wants to develop it further, they can do so without having to switch to another development firm. Companies that offer more services are also incentivized to build the right product for a business’s needs as opposed to the product that the development firm specializes in.

Blockchain Options

Most firms have experience working across several of the largest blockchains. For example, a single firm may be comfortable building apps on Ethereum, Binance Smart Chain, Avalanche, Tezos, and more. In other cases, firms specialize in just 1 or 2 blockchains.

That can be somewhat limiting for businesses, especially if the project a company has in mind is better-suited for a niche blockchain. Enterprise-scale businesses may want the option to build their own custom blockchain for internal operations. Not all blockchain development companies offer this, so it’s important to look around for a firm that does.

Design Process

One of the biggest differences between blockchain development agencies lies in how they approach the design process. Businesses can typically expect a free consultation, but quotes can take very different forms. Some firms offer a rough quote and expected completion date, while others deliver in-depth project proposals complete with mock-ups and milestones. Once design is underway, communication can take different forms.

Some development companies stay in close touch with clients, offering them frequent opportunities for review and feedback. Others work to make a lot of headway and deliver a more polished intermediate product for review. Which approach works best depends on how involved a business wants to be in the development process.

Experience

Every blockchain development company boasts about its experience, but the truth is that some blockchain companies have bigger portfolios than others.

In our reviews, we look for development firms that have worked on well-known projects or with major companies. We also look for development teams where turnover is low and the developers at the firm have a strong understanding of clients’ needs.

Pricing

Most companies offer pricing by quote only. That makes sense since every project is different. However, it can make it hard to compare pricing across development firms.

One way to approach this is to ask for a rough estimate of cost during an initial consultation. Businesses may also request quotes or proposals from multiple development firms so that they have pricing and services to compare.

Client Support

The top blockchain development firms take client relationships seriously. That means responding quickly to questions, meeting milestones and deadlines on time, and scheduling meetings proactively to keep projects moving along.

Many blockchain firms even have multiple offices around the world so that they can offer support in clients’ preferred time zones.

Conclusion

Blockchain development companies can help businesses build apps on the blockchain and jump into the Web3 economy. These companies offer teams of experienced software developers and expertise in deploying custom decentralized projects.

We have provided a range of companies that offer differing services that should fill all needs for both startup and large companies who want to get started in the blockchain or migrate their services from Web2 to Web3.
