APIs, Appchains

First Step Towards a Hybrid Multichain Ecosystem

We recently launched our Web3 APIs for the Shimmer network as the first service provider in the ecosystem. As a firm supporter of IOTA and Shimmer technologies, we also believe in building bridges between ecosystems and creating additional benefits by enabling developers to focus their varying Web3 development efforts on a single cloud-based platform.

A hybrid multichain ecosystem approach offers several benefits for the most demanding Web3 infrastructure needs:

  • Scalability, security, and efficiency through different layers and blockchain networks
  • Ability to utilize specialized capabilities of each blockchain in suitable use cases
  • Adaptivity to changing requirements, technologies, and regulations
  • Interoperability, and cross-chain asset transfers

As the first steps toward a multichain ecosystem, we are announcing API support for multiple advanced and widely adopted blockchain networks.

Multichain API Endpoints

Our cloud-based developer platform offers highly scalable Web3 APIs and dedicated blockchain infrastructure as a service. As of today, you can find multiple public network endpoints to different blockchain networks in the endpoints section of the platform. What this means is that you can use any of these public endpoints in your dApp development similar to the Shimmer endpoints. All the platform tools and analytics will work seamlessly with the other blockchain networks.

API endpoints for multiple different blockchain networks, hybrid chains, and Web3 APIs

After the release today we support all of the following blockchain networks:


Shimmer is a highly scalable, cost-efficient, and sustainable next-generation blockchain. It is optimized for hybrid chains enabling natively interoperable AppChains. We are building some of our core services on top of this highly advanced technology.



As the original and still largest smart contract ecosystem, it is a natural choice for us to provide support for the network. With more advanced next-generation blockchains entering the market we see a growing potential for cross-ecosystem collaboration and invite Ethereum developers to explore opportunities in other ecosystems as well.



Polygon is essentially a Layer 2 solution on top of the Ethereum network. They offer Supernets as a hybrid solution on Layer 3 and thus generate interest in hybrid solution projects. Support and collaboration with the ecosystem are in line with our hybrid strategy.



Avalanche is one of the vibrant new smart contract development ecosystems that has been growing rapidly in recent years. Their Subnets are one of the more advanced hybrid solutions in the market. Though still lacking in cross-chain interoperability, we see the ecosystem as a growing testbed for hybrid solution projects.


The Future of Blockchain is Hybrid

The future of blockchain is a hybrid. As enterprises learn more about the benefits of hybrid blockchain we will see wider adoption of hybrid solutions. We are also witnessing a growing interest in other ecosystems as protocols are pivoting and working towards more advanced and streamlined hybrid solutions. This is one of the main reasons for our multichain approach and building support for the chosen blockchains.

Appchains on Shimmer

One of the advances Shimmer has towards the other ecosystems is that it is optimized for hybrid chains and has native cross-chain interoperability. Our recently released AppChains will enable anyone to start testing hybrid chains on the Shimmer network. As a limited-time offer, you can launch your AppChains on the Shimmer Testnet for FREE.

Invitation to Cross-Ecosystem Collaboration

At the HAVN ecosystem, we celebrate and promote cross-ecosystem collaboration and we are constantly looking for ways to “build bridges” between ecosystems. We are united in our mission to increase blockchain adoption on a global level and believe that suitable and most performant technologies will find the right developers and projects for different use cases and needs.

One example of our efforts was the Battle of Blockchains event organized in collaboration with IOTA, Cosmos, Lisk, LUKSO, and CV Labs during the Berlin Blockchain Week in September. There is more to follow and we’ll be announcing something exciting soon.

The path toward explosive growth is still ahead of us and we invite developers from other ecosystems to join us in taking the whole industry to the next level.

Get started with dApp development for free and get your API Key from the HAVN Launchpad. Start experimenting with AppChains in the most advanced hybrid chain ecosystem to date.

HAVN Labs offers highly scalable Web3 infrastructure as a service for the most demanding performance and scaling needs. We are building our services on the Shimmer network, the most scalable, cost-efficient, and sustainable distributed ledger technology on the planet.
