External modules

Overview

In this section, you'll find descriptions of external Cosmos SDK modules used by the Warden Protocol. For more details, follow the provided links to external documentation.

x/evm

The x/evm module is a Cosmos SDK module by Evmos that allows for the deployment of smart contracts, interaction with the Ethereum Virtual Machine (EVM), and the use of EVM tooling.

To start using x/evm, follow this guide:

• Deploy an EVM contract

Learn more:

• x/evm in Evmos documentation
• x/evm on GitHub

x/wasm

The x/wasm module is a Cosmos SDK module that processes certain messages and uses them to upload, instantiate, and execute smart contracts. It's an integral part of CosmWasm – a smart contract platform that can be integrated into any blockchain built on top of the Cosmos SDK.

To start using x/wasm, follow this guide:

• Deploy a WASM contract

• CosmWasm Contract Semantics
• x/wasm on GitHub

x/gmp

The x/gmp module is a Cosmos SDK module that enables Axelar GMP (General Message Passing): sending and receiving messages on EVM and Cosmos chains.

GMP allows smart contracts on one chain to send messages and data to smart contracts on another chain. This technology can be used for various purposes: token transfers, data sharing, or triggering actions across chains.

To start using x/gmp, follow this guide:

• Deploy a cross-chain app

x/oracle

The x/oracle module is a Cosmos SDK module by Skip Protocol that enables storing prices on-chain in Skip:Connect (an oracle service).
