Ankr is excited to announce the launch of AB Chain RPCs on our Web3 API service. AB Chain is a heterogeneous blockchain network designed to power stablecoins, payments, and interoperable digital financial infrastructure across multiple chains.

With Ankr’s AB Chain RPCs, developers can make request calls and receive responses identical to running their own AB node, without needing to manage infrastructure. This gives builders reliable, low-latency access to AB Chain’s network for powering payment systems, stablecoin platforms, and cross-chain applications.

What Is AB Chain?

AB Chain is part of the AB blockchain ecosystem, a heterogeneous multi-chain network designed to support next-generation onchain payment infrastructure and stablecoin economies.

The network focuses on building a stable, transparent, and accessible payment network that connects digital assets, financial infrastructure, and decentralized applications across multiple chains.

AB Chain enables efficient interoperability between blockchains while supporting advanced financial primitives such as stablecoins, cross-chain assets, and tokenized real-world assets (RWAs).

Key characteristics of AB Chain include:

Heterogeneous Multi-Chain Architecture

AB operates as a heterogeneous blockchain network designed to connect multiple chains through a unified cross-chain transport layer. This architecture enables efficient interoperability for both assets and data across ecosystems.

Cross-Chain Asset Interoperability

Through AB Connect, the network links AB Core with dedicated sidechains and major public blockchains. This design allows AB-based assets to move freely across chains, making AB tokens function as truly omnichain assets.

Built for Stablecoins and Payments

AB Chain is optimized for financial use cases such as stablecoin issuance, payment infrastructure, and multi-asset transaction settlement. The network supports fee abstraction and flexible transaction payments, improving usability for both developers and end users.

Advanced Protocol Layer

AB integrates several specialized protocols to support its ecosystem, including:

UTP Protocol enabling fee abstraction, multi-asset fee settlement, and heterogeneous-chain payments.

EVT Protocol supporting encryption, traceability, variability, and tokenized real-world asset infrastructure.

These systems combine to create a foundation for scalable digital payments and financial services.

Why the Combination of AB Chain and Ankr Works

AB Chain is designed to support high-throughput financial infrastructure such as payment rails, stablecoin systems, and cross-chain transactions. These applications require reliable, low-latency RPC infrastructure to maintain smooth user experiences and dependable application performance.

Ankr’s RPC infrastructure is built to meet these requirements. Operating on its own global fiber network with bare-metal nodes and a custom blockchain-native load balancer, Ankr avoids the performance limitations commonly associated with cloud-based RPC providers.

This infrastructure allows Ankr RPCs to maintain consistent performance even under heavy request loads, making them well suited for AB Chain’s payment-focused ecosystem and multi-chain architecture.

Together, AB Chain’s financial infrastructure layer and Ankr’s high-performance RPC network provide a strong foundation for developers building the next generation of onchain payment and stablecoin systems.

What Are Ankr’s AB Chain RPC Connections?

Ankr’s AB Chain RPCs (Remote Procedure Calls) connect wallets, developer tools, and decentralized apps directly to AB Chain nodes.

These RPC endpoints act as the communication layer between your application and the AB network, enabling developers to:

• Send and simulate transactions
• Read smart contract state and blockchain data
• Fetch balances and asset ownership information
• Power payment systems, DeFi applications, and stablecoin infrastructure

AB Chain RPC endpoints allow developers to interact with the network without managing their own nodes or infrastructure.

Ankr provides a geo-distributed AB Chain RPC setup, with nodes running globally to ensure low latency and reliable connections.

How Do AB Chain RPCs Help Developers?

Building on AB Chain offers powerful opportunities for payment and stablecoin infrastructure, but it also requires dependable access to onchain data. Ankr’s RPCs help developers by:

Removing node infrastructure overhead

Developers do not need to deploy or maintain their own AB Chain nodes.

Providing reliable, low-latency access

Apps connect to a global cluster of high-performance nodes optimized for fast execution.

Supporting cross-chain financial infrastructure

Developers can build payment networks, stablecoin platforms, and interoperable DeFi systems powered by AB Chain.

Strengthening the AB ecosystem

By expanding RPC availability globally, Ankr helps support developer adoption and network reliability.

How to Make Your First Call to AB Chain

You can start building on AB Chain today by heading to Ankr’s RPC Service and accessing the AB Chain endpoint.

AB Chain RPCs enable developers to quickly integrate with the network and build applications for payments, stablecoins, and cross-chain infrastructure.
