Smart Contracts on Egochain

Build with Solidity

You can develop EVM smart contracts on Egochain using Solidity, the same programming language used for building smart contracts on Ethereum. If you have experience deploying contracts on Ethereum or any other EVM-compatible chain, you can easily migrate those contracts to Egochain. Solidity's widespread use in blockchain development means it comes with extensive documentation and robust language support. Visit our list of tools and IDE plugins to get started.

EVM Extensions

EVM Extensions are precompiled contracts built into the Ethereum Virtual Machine (EVM), each offering specific functionalities that other smart contracts can utilize. These extensions handle operations that are either impossible or too costly to execute with regular smart contracts, such as hashing, elliptic curve cryptography, and modular exponentiation.

By incorporating custom EVM extensions into Egochain, developers can leverage previously unavailable functionalities in smart contracts, such as staking and governance operations. This enhancement allows for the creation of more complex smart contracts on Egochain and improves interoperability between Cosmos and Ethereum. It is a crucial step towards realizing Egochain’s vision of being the definitive dApp chain, enabling seamless deployment and interaction with various blockchains.

To support these functionalities, Egochain introduces stateful precompiled smart contracts that can perform state transitions, unlike the standard Go-Ethereum implementation, which only reads state information. This capability is essential for operations like staking tokens, which alter the chain state.


Blockchain oracles bridge the gap between smart contracts and external information sources, such as price feeds from financial exchanges or carbon emission measurements. These oracles enable smart contracts to access real-world data, facilitating applications in insurance, borrowing, lending, and gaming. Explore our Oracles section to learn how to integrate oracles with your smart contracts on Egochain.

Deploy with Ethereum JSON-RPC

Egochain’s compatibility with Ethereum JSON-RPC APIs allows you to deploy and interact with smart contracts on Egochain and connect with existing Ethereum-compatible web3 tooling. This compatibility provides direct access to reading and sending Ethereum-formatted transactions on Egochain, capabilities that are not typically possible on a Cosmos chain. Connect to the Egochain Testnet to deploy and test your smart contracts before moving to Mainnet.

Block Explorers

Utilize block explorers to view and debug interactions with your smart contracts deployed on Egochain. Block explorers index blocks and their transactions, enabling you to search for real-time and historical blockchain data, including information on blocks, transactions, addresses, and more.

Contract Verification

Once deployed, smart contracts are represented as non-human-readable EVM bytecode. Contract verification tools allow you to publish and verify your original Solidity code, proving to users that they are interacting with the correct smart contract.

Egochain Features

The Egochain core protocol team continually develops features that enhance the experience for smart contract developers. Visit our Mainnet sections to learn more about these functionalities, such as earning revenue with your smart contract or registering your ERC-20 token for cross-chain use.
