A blockchain API is an API that facilitates developer interactions with blockchain networks. Its main aim is to streamline the integration of blockchain technology into applications and websites. By offering this interface, a blockchain API simplifies how developers engage with blockchain networks, aiding in creating decentralized applications. It grants access to a wealth of data, including information on transactions, blocks, smart contracts, account balances, and other details.

The most common blockchain APIs developers use are the standard ones, typically structured in the JSON-RPC architecture. These APIs are accessible through HTTPS or WebSockets, enabling developers to send transactions or retrieve blockchain data. Furthermore, developers can employ standard software development kits (SDKs) such as web3.js or for seamless interaction with blockchains.

Beyond these standard APIs, there exist various advanced or enhanced API types that offer significant development benefits. Notable examples include Defi APIs, NFT APIs, and Wallet APIs, all of which build upon the foundation of standard APIs. Enhanced APIs typically rely on blockchain data indexing and serve as a caching layer for applications. They come with advantages and disadvantages; for instance, enhanced APIs streamline data aggregation for developers across different use cases, eliminating the need for developers to perform data indexing and aggregation tasks themselves. However, it’s important to note that there is no standardization for enhanced APIs, potentially leading to application portability issues when using them.

How do financial companies use Blockchain APIs?

Using Blockchain APIs in BFSI use cases in many ways, such as empowering the development of decentralized applications, providing secure data storage, fuelling cryptocurrency and financial technology solutions, facilitating digital identity authentication and authorization, and more.

Cross-Border Payments: Blockchain APIs can facilitate faster and cost-effective cross-border payments by connecting to blockchain networks like Ripple or Stellar. These APIs enable real-time settlement, reducing the need for intermediaries and resulting in lower fees and improved efficiency. 

Smart Contracts: BFSI institutions can use Blockchain APIs to create and execute self-executing smart contracts. These contracts automate processes like loan approvals, insurance claims, and trade finance, reducing manual intervention and the risk of errors. 

Identity Verification: Blockchain APIs can enhance identity verification and Know Your Customer (KYC) processes by securely storing and verifying customer data on a Blockchain, which reduces the risk of identity fraud and simplifies compliance with regulatory requirements. 

Trade Finance: Blockchain APIs can digitize and automate trade finance processes, including letter of credit issuance, invoice financing, and supply chain tracking. This improves transparency and reduces fraud risks in international trade.

Securities Settlement: Blockchain APIs can streamline securities settlement by enabling real-time, peer-to-peer transactions of financial assets. This reduces settlement times, minimizes counterparty risk, and lowers operational costs. 

Asset Tokenization: Blockchain APIs enable the tokenizing of physical and digital assets, allowing BFSI institutions to create and manage digital representations of assets like real estate, stocks, or bonds. These tokens can be traded and transferred more efficiently. 

Regulatory Compliance: Blockchain APIs can assist in regulatory reporting and compliance by providing immutable records of transactions and financial data, simplifying auditing processes, and ensuring data accuracy. 

Insurance Claims Processing: In the insurance sector, Blockchain APIs can automate claims processing by using smart contracts to trigger Payouts based on predefined conditions. This reduces the time and administrative costs associated with claims handling. 

Credit Scoring: Blockchain-based credit scoring APIs can improve the accuracy of credit assessments by considering a wider range of data sources, including payment history on the Blockchain. This can expand access to credit for underserved populations. 

Data Security: Blockchain APIs can enhance data security by storing sensitive information on a decentralized, tamper-resistant ledger. This reduces the risk of data breaches and unauthorized access. 

Tokenized Assets: Blockchain APIs can create and manage tokenized assets, such as stable coins or security tokens. These assets can have integrated into various financial products and services. 

Supply Chain Finance: Blockchain APIs can facilitate supply chain financing by providing transparency into the movement of goods and enabling real-time financing options for suppliers. 

These are just a few examples of how Blockchain APIs are utilized in the BFSI sector to improve efficiency, security, and transparency while reducing costs and risks. The adoption of Blockchain technology in BFSI continues to evolve, with new use cases and innovations emerging regularly. 

We invite you to get in touch with our Blockchain experts, who have provided their insights to debunk some of the common myths associated with Blockchains.

Myth #1: Using Blockchain means using Bitcoin and cryptocurrency

People have a common misconception about Blockchain technology, assuming putting themselves at risk and subjecting themselves to the instability of Bitcoin. Blockchain is a technology, a decentralized digital ledger, that records transactions across multiple computers. It is the infrastructure as a medium for transferring cryptocurrencies. Bitcoin is a specific cryptocurrency that operates on a blockchain.

It’s just one application of blockchain technology, and there are thousands of other cryptocurrencies and countless non-cryptocurrency applications of Blockchain. Using blockchain technology does not necessarily involve using or dealing with Bitcoin or any other cryptocurrency. Blockchain can harnessed for many use cases that have nothing to do with digital currencies.

Myth #2: Blockchains are vulnerable to hackers as they are public in nature

This myth oversimplifies the concept of public blockchains. While public blockchains are open to anyone, they are designed with robust security mechanisms that make them highly resistant to manipulation. Public blockchains rely on decentralized consensus mechanisms, such as Proof of Work (PoW) or Proof of Stake (PoS), which require participants (miners or validators) to solve complex mathematical problems or stake cryptocurrency to authenticate transactions and secure the network.

The vast size and distribution of nodes in a public blockchain network make it highly challenging for any single entity, including potential hackers, to manipulate the Blockchain. Additionally, the immutability of past transactions further safeguards the integrity of the blockchain ledger. While public blockchains are transparent, they are not inherently vulnerable to manipulation due to their decentralized and secure nature.

Myth #3: The proliferation of blockchain technology will increase criminal activity

While blockchain transactions are pseudonymous, meaning they use cryptographic addresses rather than real names, this does not inherently lead to increased criminal activity. Blockchain technology can also enhance transparency and security in many industries, including finance. Moreover, blockchain networks are often designed with robust security features and audit trails.

Regulatory authorities are working on frameworks to ensure that blockchain technology is used responsibly and complies with anti-money laundering (AML) and know-your-customer (KYC) requirements. While bad actors can misuse Blockchain, its potential benefits in reducing fraud and improving traceability should not be overlooked. Responsible adoption and regulatory oversight can mitigate the risks associated with anonymity on the Blockchain.

Myth #4: Blockchain is fit for modern FinTech companies, not traditional banks

This misconception is far from the truth. Thousands of Banks have shown significant interest in blockchain technology for its potential to revolutionize financial services. They are exploring Blockchain to improve efficiency by automating processes like cross-border payments and settlements, enhancing security through cryptographic features, and boosting transparency for regulatory compliance.

Banks are also considering Blockchain for identity verification and digital asset services. While they approach blockchain adoption thoughtfully due to regulatory considerations, they are eager to leverage its capabilities to streamline operations, reduce costs, and offer innovative financial solutions to their customers.

Myth #5: Adopting Blockchain does not mean re-engineering entire financial infrastructure

Organizations can selectively integrate blockchain technology without the need for a complete rebuild. However, all banks already have tools and platforms designed to send and receive funds. To enable their bank customers to use blockchain rails, many of these tools and platforms, including ECS Fin’s Payment Hub, can easily connect to APIs provided by blockchain firms. Blockchain solutions are often modular and interoperable, allowing them to complement rather than replace legacy systems.

Financial institutions can begin with specific use cases where Blockchain provides clear advantages, such as improving cross-border payments or enhancing transparency in supply chains. As industry standards and regulatory frameworks evolve to accommodate Blockchain, adoption becomes a gradual and pragmatic process that enhances existing infrastructure rather than replacing it entirely.


Blockchain is not synonymous with cryptocurrencies; it’s a versatile toolset that can streamline cross-border payments, enhance security through smart contracts, and revolutionize identity verification and KYC processes. The myth that Blockchain demands a complete infrastructure overhaul has shattered, revealing its modular and incremental nature. In reality, banks are not only interested in Blockchain but are actively exploring its vast benefits across various applications. The misconception that Blockchain’s anonymity fosters criminal activity has been dispelled, emphasizing responsible adoption and regulation as the path forward. As we conclude our exploration, one fact remains abundantly clear: blockchain technology is a guiding light, illuminating a path toward enhanced efficiency, security, and transparency in the BFSI sector.

BFSI organizations can handle the difficulties of the modern financial world by adopting these blockchain principles, offering their customers a more resilient, secure, and innovative future. The myths may have clouded the way, but Blockchain’s truths pave the path toward a brighter future in BFSI.
