Ault RPC
What is Ault?
Ault is a blockchain platform designed for tokenized market access and on-chain financial applications. It is built on the Cosmos SDK and uses CometBFT proof-of-stake consensus to provide fast transaction finality and deterministic execution. The network offers full EVM compatibility, enabling developers to deploy Solidity smart contracts and use standard Ethereum tooling while operating within a Cosmos-based architecture.
In addition to EVM support, Ault also supports CosmWasm smart contracts written in Rust, allowing developers to build interoperable applications across the Cosmos ecosystem. The protocol implements an EIP-1559-style fee market for gas pricing and fee management. Financial functionality such as trading and lending is provided through on-chain applications and protocols deployed on the network, rather than as base-layer features. Governance and network operation are organized under a Wyoming DAO LLC structure, with participation by licensed node operators.
Interacting With Ault's APIs
Ault nodes expose multiple API interfaces to support different development workflows:
- Ethereum JSON-RPC API: Fully compatible with Ethereum's JSON-RPC interface, allowing developers to use familiar tools like Foundry, Hardhat, ethers.js, viem, and web3.py without modification.
- Tendermint RPC API: Native Cosmos SDK interface for querying blockchain data, blocks, transactions, and network information.
- Cosmos REST/gRPC API: RESTful and gRPC endpoints for interacting with Cosmos modules, including bank, staking, governance, and custom application logic.
However, due to Ault's architectural differences from standard Ethereum chains, some RPC methods may behave differently. The Quicknode Ault documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official Ault documentation for the latest updates and RPC differences.
