Our Mission

You can read it everywhere: Blockchain is the Future! Still, there are not many real-world use cases that make use of Blockchain Technology. “How can this be?” – You might be asking. Well, there are some reasons which prevent companies and countries to implement blockchain technology.

The biggest reason, in our opinion, is the difficulty of implementation. The median salary for a blockchain developer is about $172,000 per year. Not many companies have the budget to develop decentralized applications. Also, another disadvantage is the user-friendliness. Many end users have difficulties using their computers and smartphones, how are they supposed to know how to setup a secure wallet and use Dapps? They simply won’t.

We offer a solution for those problems – Chaingateway.io. We trust in our vision that applications do not have to be fully decentralized. With a bridge to the normal web every developer can use blockchains the way he wants with a simple REST API. Making it easy to implement, use and retrieve information from them without having to worry about security, infrastructure and high costs.

Use Cases


Exchanges can use our Blockchain API to offer trading with Ethereum, Tron and all Tokens they wish to offer. Deposits and withdrawals can be completely automated.

ICOs and Airdrop Organizers

As our Blockchain API is working with all Tokens, and requires no listing, it is a good option to distribute tokens automated to a large audience.


Online shop merchants can use Chaingateway.io as a payment gateway to offer various cryptocurrencies in their online shops. They can even start accepting their own Token or existing stable coins. Our Blockchain API will be able to handle it and provide the required functions.

You have questions? We have the answer!

Chaingateway.io is a REST API which allows you automate interacting with the Ethereum and Tron blockchain. So, instead of using a wallet to manually send coins to many addresses, you can automate this process by using our solution. You can also use Chaingateway.io to securely store and manage ethereum funds of your users.

You can, for example: Check Token balances, send Ethereum, Tron or Tokens, create Ethereum and Tron addresses, get info on ERC20, ERC721 tokens and Ethereum transactions. For a full overview please have a look at our Ethereum Docs and Tron Docs which describe all available functions of our Blockchain APIs.

Cryptocurrency Exchanges, ICOs, Airdrop managers, E-Commerce shops which want to add their own token as a payment method and all businesses which need to interact with blockchains.

We have a monthly pricing system with different plans. You will start with a free plan, but can upgrade it at any time if you need to make more requests. To upgrade, you only need to select a plan on the pricing page and have enough balance on your account. To charge your account, you only need to send Ethereum to the address in your account panel. After a few confirmations (~30 minutes), it will automatically be accepted and converted to dollar based on the current dollar to ethereum rate and added to your account balance. To get an overview of our plans, please click here. We also offer customized plans for customers who need to make a lot of requests. If you have a big application and want to use Chaingateway.io, please get in touch with us so we can negotiate a fair price (You can find ways to contact us at the bottom of the page).

Your token must follow the ERC20, ERC721, TRC20 TRC721, BEP-20, BEP-721 or TRC10 token standard for our API to work. Please refer to this article to see the exact specifications of the ERC20/TRC20/BEP-20 token standard. If your token follows the standard, it will work with the Blockchain API of Chaingateway.io. There is no need to ask us if we will add a specifc TRC20 or ERC20 Token, as our Blockchain API is designed to be universal compatible with all tokens.

Sure! We are happy to provide discounts for applications which need a lot of requests. Just get in contact with us.

We have a lot of costs to keep our Blockchain API up, redundancy and secure. Saving and backupping of important account data is also costing us money on a permanent base, so we decided to add a total limit of wallet addresses to every plan to offer a good performance. Creating Tron addresses will count as wallet addresses, as they are not being saved on our systems.

Our Blockchain API is being improved continuously. We can currently compensate over 50% of system failures and are working with high available, shielded servers.

You can manage your wallets with the functions newAddress, listAddresses and deleteAddress. NewAddress creates a new address on the Ethereum API with the password you provided (Don’t lose that one!). In Tron API, the newAddress function will return a private key (which shouldn't be lost also). With the listAddresses function, you can get a list all of the wallet addresses you have ever created. If you have Ethereum addresses you don't need anymore, you can use the deleteAddress function to get rid of them. But be careful, you won't have access to it anymore after it has been deleted.

When you register, you start with the free plan, which you can use for testing purposes also. If you need to make more requests for testing purposes, we are happy to reset your limits. Just get in contact with us.

Our Blockchain API supports all Stable Tokens that are based on the ERC20, TRC20 and TRC10 standard. This includes Tether (USDT), TrueUSD (TUSD), MakerDAO (DAI), Paxos Standard (PAX) , Gemini Dollar (GUSD) and USD Coin (USDC)
