Blockchain in Action – 16 Inspirational Examples
Zabo provides an API to connect any cryptocurrency exchange, wallet, or account. Using Zabo API you can easily fetch information from crypto accounts, including:. To see a complete list of cryptocurrency exchanges, wallets, and accounts Zabo supports, check out our integrations page.
The fastest, easiest way to get started with Zabo in less than 5 minutes is through our Sandbox and Quickstart app, both of which can be accessed by signing up for Zabo API. If you have any questions about Zabo or feedback on these docs, you can contact us or find us here:.
Zabo provides two distinct environments through the API, a sandbox environment and a live environment. The sandbox environment produces the same exact objects and data structures as the live environment, however, the data itself is not meant to be precise.
The sandbox server will not connect to real cryptocurrency exchange accounts, and it does not provide accurate exchange rate data. Market rates are close to the current market for all major currencies, however, you must use the live server to connect to real accounts and obtain accurate data. The live server should be used when your application is ready to connect to a live server and have proper security built around your API keys and any data your application intends to receive.
You must also receive approval to connect with our live servers. Before then, the sandbox is available for development purposes. Keep this in mind when observing data obtained from the Zabo sandbox servers.
Let's begin by looking at how we initialize a connection. You are ready to connect a user once Zabo has been initialized! To do this, provide a way to trigger the connect function, such as a button, and give a callback function to the onConnection handler.
That's it! You now have an account object and the rest of the API at your fingertips. Keep reading to see how you can create multiple connections for one user. To add multiple wallets to one user, we set up Zabo in your server. The SDK operates the same way on the server-side, but with different initialization credentials.
You need to create an API key pair in the dashboard if you haven't done so already. Copy the public and private keys into a private file in your project. NOTE : The secret key will not be available after you leave this view. You will need to generate a new key pair if the secret key is lost. Now you should load those keys into your server and initialize the SDK. We return to the point we left in the previous section.
After the user connects an account in the front-end of your application, we move the account to your server in the onConnection callback. This must be done in the onConnection callback, or whichever method is used to capture the initial connection. You will not be able to call accounts. To add another account to this user, simply provide a way for the user to connect another wallet in the front-end. NOTE : Two accounts cannot be connected in the front-end together.
Only the latest connection will be directly active in the client. Requests for an account that is not actively connected in the front-end, but is connected to a user, can be made through the server. We're excited to see what you build with all of the cryptocurrency at your fingertips! If you are ready for more advanced cryptocurrency features, read on.
Zabo integrates a variety of wallets and currencies, each with its own set of capabilities and limitations. One of our primary goals for Zabo is to allow you to navigate these limitations programmatically, not manually. For instance, we have a provider endpoint available for you to get a full list of supported providers. This listing can give you a high-level overview of support for each of these components.
If you notice anything that is not clear, please reach out to us and let us know. See more details in our 'Ethereum API' section below. Most endpoints that return a list provide cursor-based pagination. The SDK can handle pagination for you if using it as your tool. You can see examples of this to the right. If using the REST API directly, you can paginate through the results by using the id of the last resource in the list as a cursor parameter for the next call.
The default limit is 25, but values up to 50 are permitted. We provide all lists in descending order only newest item first. This documentation explains Zabo integration in your application. We recognize that many decentralized applications do not run a server, so we do not require an application server to interact with Zabo. With that said, we do have the ability to work with your server-authenticated users, which opens up two different ways you can connect with user wallets, depending on your application's setup.
See Authentication for further information. You can view code examples in the dark area to the right as you read through the documentation.
The Zabo API section defines the functions available for use in your application. These functions provide a way for your user to connect a wallet of their choice and provide the cryptocurrency data your application needs.
After connecting, the client and server API functions can be accessed from your application's client or server, respectively. Both environments share similar functions, and they have unique functions of their own. If you are only using the API from your application client, the account connection lives for as long as the user's session token remains unexpired in the client.
After that, the user needs to connect their account again. If you are running a server that authenticates your users and would like a persistent connection, then you can use the server-side API to assign users with established accounts. Application developers should note that Zabo provides a simple interface with networking in our back-end to facilitate a better overall cryptocurrency developer and user experience.
At no point do we obtain user wallet private keys or any sensitive data required to act upon cryptocurrency holdings independently. All authentication and approvals remain in the user's hands. The Zabo API has a rate limit of 5 requests per second for session calls where you're using an account session token , and this limit is shared across all session endpoints.
It's IP-based, so every client would have their own rate limit. To help you keep track of your rate limit and adjust your calls dynamically if you should need to , many of our endpoints will also respond with the following custom headers to help you keep track of your rate limit use:.
This will speed up our ability to help you! The Zabo API requires your users to authorize a connection to the wallet they choose. Before getting to this point, you must register your application with us , develop using our sandbox environment, then activate your team or contact us to go live.
Once the user has connected a wallet, your application can use the various Zabo functions to pull in data and provide it to your users. The user's approval happens when a user action triggers the connection widget, or you make the call for a connection using your specific URL screenshot below through tools such as mobile WebView. From there, Zabo takes the user through the process of selecting the wallet and currencies available.
When the user returns from establishing a connection, the zabo. See the callback documentation and Connecting a User for further details.
If you're running a front-end only application, users receive a session token that initializes the Zabo SDK for JS in the client, and you do not need to take any further action for authentication. Session tokens do have a limited time-to-live depending on user activity and, once it expires, your user needs to connect again.
If you are sending REST calls, you authenticate with a Bearer token and all calls must be made from https origins. The requests must have the following header:. This communication link provides programmatic access to administrative functions and provides a unified experience for your authenticated users and Zabo. You must establish API keys through your Zabo administrative dashboard after registering your application. You can create API Keys in the dashboard and use them to sign and send requests from your server.
These requests must be signed and have the following headers:. The Zabo NPM package will do this under the hood for you once initialized. Once a user is established in the system, with an account linked, the application server can send future authenticated requests for data. Zabo uses promises to return most responses. When implementing the catch function, the SDK provides an error object with the following error types:.
Sometimes Zabo will lose the connection to an account after making a successful connection. While we strive to maintain an active connection for as long as you need it, these disconnects happen for reasons outside of our control. These happen for reasons such as the user has revoked the access credentials directly in their account, the account provider has caused the credentials to expire, or the account provider simply does not support persistent connections.
We are working to provide more useful responses when this happens, however, in Zabo API's current state, an account request for balances or transactions will return an error response if the account has disconnected.
You should expect to handle the following errors:. Our next update to this process will seek to remove the error workflow completely, and provide some account data along with connection information. Due to limitations with certain wallet providers, some functions will not work if the user connected to a wallet provider that does not support those functions. Your application should plan to handle these errors gracefully. Each function will list the current wallet provider support level.
If a function is called, and the connected wallet provider does not support it, your application can expect to receive the error object to the right. This process should begin when the user indicates they would like to establish a new wallet connection, such as after pressing a button. You can establish a connection with or without the SDK and keep the account in the client, or you can send this account object to your server and establish a server-side connection with Zabo.
This server process allows you to link the account to a user.
Create an API to interact with Ethereum Blockchain using Golang PART 1
The role of a CIO chief information officer in the corporate world has evolved over time, keeping pace with the rate of innovation characteristic in technology and business. As technology moves away from the monolithic model and into a mix-and-match paradigm, APIs have become a key component for success. APIs application program interfaces are sub-functions, or small applications, that allow developers to use different tools in a single solution by enhancing communication between different components. In essence, APIs act as communicators between two pieces of software, enabling both to work as if they were a single program. APIs have become increasingly popular tools, with companies like Facebook, Amazon, SalesForce, and more launching their own APIs which allow companies to access some of their services without having to fully migrate into their ecosystem. Much in the same way businesses today are building new platforms not from single sources but from a variety of applications, blockchain technology offers a more democratic and efficient way to construct new solutions. Blockchain is founded upon the idea of democratization and decentralization, two notions that are inherently built into API development paradigms.
Binance Python API – A Step-by-Step Guide
Any issue related to bitcoins is invariably linked to blockchain , the technology on which the cryptocurrency is based. The end result is a huge database distributed in numerous servers all around the world that gathers all the transactions made in bitcoins. Each one of these operations, encrypted and authenticated, is added to the chain of blocks —or blockchain— on which bitcoins are based. This process would be impossible without APIs. The fact is that today, bitcoin technology offers many more possibilities and arouses more interest among developers than other online payment systems such as PayPal, for example. Currently within the collaborative development platform GitHub there are almost 3, repositories linked to PayPal , whereas there are over 8, repositories linked to bitcoin. This fever chart compiled by CoinDesk shows the annual growth of both systems since
Blockchain technology allows for the creation of a decentralised public record of digital information. The data the block is stored in a public database the chain and can consist of any information. It is the first digital technology that offers a way for unsecured parties to refer to a common, indelible append-only digital record. Bitcoin One of the more famous examples of Blockchain in action is Bitcoin.
The World’s Most Powerful Blockchain Development Suite
Monetary Policy Principles and Practice. Exchange Rates and International Data. Introduction Discussions of financial technology have recently started to include the idea of "programmable money," though the specific meaning of the term is often unclear. Different perspectives may presume a particular underlying technology or set of features to be a part of a programmable money system, and lack of agreement on these aspects may lead to confusion. To support clearer discussion of this concept in the central banking community and the financial industry more broadly, this research note offers an investigation into the nature of programmable money. This note focuses on the importance of a mechanism guaranteeing the inseparable functionality of the technical components of a programmable money system rather than prescribing the specific nature of those components.
A Deep Dive Into The Graph
Amazon Managed Blockchain is a fully managed service that makes it easy to join public networks or create and manage scalable private networks using the popular open-source frameworks Hyperledger Fabric and Ethereum. Blockchain makes it possible to build applications where multiple parties can execute transactions without the need for a trusted, central authority. Today, building a scalable blockchain network with existing technologies is complex to set up and hard to manage. To create a blockchain network, each network member needs to manually provision hardware, install software, create, and manage certificates for access control, and configure networking components. Once the blockchain network is running, you need to continuously monitor the infrastructure and adapt to changes, such as an increase in transaction requests, or new members joining or leaving the network.
