Public RPC Guide

Introduction to Stability RPC

The Stability RPC is a critical component that allows applications to connect with a Stability node within the Stability Blockchain Network. It enables users to access on-chain data through specific endpoints or via a user interface that employs these endpoints as its backend. Adhering to the JSON-RPC standard, it offers a consistent method set that is independent of specific applications or nodes, ensuring a lightweight and stateless interaction using JSON (RFC 4627).

In addition to supporting standard Ethereum/Geth-compatible endpoints, the Stability JSON RPC API also includes custom endpoints tailored to the unique needs of our ecosystem.

For Ethereum API specifics, refer to the Ethereum API Documentation.

EVM RPC Endpoints

Stability Testnet Access

The Stability Public Testnet RPC facilitates blockchain reading and permits up to 20 transactions per address daily. Users requiring more transactions can obtain a free API key by visiting our Getting Started page.

  • RPC URL:
  • Chain ID: 20180427

Global Trust Network Mainnet Access

The Global Trust Network (GTN) Public RPC is read-only for the blockchain. Transaction execution is not available through the GTN Public RPC. Users looking to perform transactions should acquire a free API key as detailed on our Getting Started page.

  • RPC URL:
  • Chain ID: 101010

Stability Custom RPC Endpoints

Our networks feature a suite of custom RPC endpoints developed by the Stability Team to enhance our ecosystem's functionality:

  • stability_getValidatorList: Retrieves the current validator set, listing the addresses authorized to maintain the network.

  • stability_getActiveValidatorList: Fetches the current active validator set, listing the addresses actively involved in network maintenance.

  • stability_getSupportedTokens: Provides a list of tokens supported by the network. This experimental feature paves the way for future transaction payment options with network-supported tokens.

  • stability_sendSponsoredTransaction: Enables the submission of sponsored transactions to the network's mempool, allowing transactions without the sender directly paying the fee. This experimental feature introduces a scenario where transactions are submitted by users and executed by sponsor wallets.

Usage Example

The following command illustrates how to query the supported tokens using the stability_getSupportedTokens endpoint:

curl '' \
-H "Content-Type: application/json" \
--data '{"method":"stability_getSupportedTokens","params":[], "id":1,"jsonrpc":"2.0"}'
