ZetaChain is the first ever L1 blockchain to enable fully interoperable smart contracts, or omnichain smart contracts, that connect all blockchains and bring the power of programmability to non-smart contract chains like Bitcoin and Dogecoin. We provide an unparalleled combination of security, simplicity, and flexibility for developers.
Built for an unparalleled developer experience
Deploy Once, Access All Chains
Manage a single omnichain contract for all chains, instead of one contract for each supported chain. Experience the simplicity of building on Ethereum with access to assets on any chain, even non-smart contract chains like Bitcoin.
Fewer Transactions, Fewer Fees
Complex contract logic on ZetaChain can orchestrate assets across all connected external chains through simple transfers and single transactions, minimizing total gas expenditure and slippage for users.
Safer, Better User Experience
Transaction logic occurs atomically in our smart contracts, resulting in lower slippage, reduced attack surface, and less susceptibility to race conditions. Experience truly one-step transactions (and fees), even when operating across chains.
The best DevX = The best UX
Omnichain Smart Contracts and Messaging give you a complete toolkit to easily build intuitive, traceable, single-step transactions so your users don’t get stuck or risk their funds.
The easiest, most versatile cross-chain platform
To interact with the ZetaChain blockchain, implement 3 functions into your dApp to get intuitive, traceable, revertible behavior so your users don't get stuck or risk their funds.Start using Connector API →
* @dev Sending value and data cross-chain is as easy as calling connector.send(SendInput)
function send(ZetaInterfaces.SendInput calldata input) external;
* @dev onZetaMessage is called when a cross-chain message reaches a contract
function onZetaMessage(ZetaInterfaces.ZetaMessage calldata zetaMessage) external;
* @dev onZetaRevert is called when a cross-chain message reverts.
* It's useful to rollback to the original state
function onZetaRevert(ZetaInterfaces.ZetaRevert calldata zetaRevert) external
ZetaChain's omnichain primitives give developers the ability to deploy applications once and orchestrate assets on any connected chain from a single place of logic.
Omnichain Smart Contracts
Leverage the existing Ethereum smart contract ecosystem and build truly interoperable apps on ZetaChain as if everything were on a single chain.Learn more →
Send arbitrary messages and move real value without the need for wrapping or locking assets, from any chain to any chain.Learn more →
ZetaChain’s novel TSS architecture lets users and contracts custody and manage assets from a single place, in a secure and decentralized manner.
Fully explorable transactions: View and monitor ZetaChain internal transactions as well as transactions occurring from any chain to any chain.
How does ZetaChain compare?
As a blockchain and smart contract platform, ZetaChain provides a fully public, transparent, decentralized interoperability solution that supports both omnichain messaging and smart contracts. Developers on ZetaChain only need to implement their dApp logic, while ZetaChain handles the transaction of data and value across chains in a trust-minimized way.
ZetaChain is a decentralized network built with TSS and PoS Tendermint Consensus with a minimal attack surface.
No wrapped assets, centralized bridges, or increased interdependency risks. More freedom and cheaper transactions.
ZetaChain can support any existing or new blockchain, even non-smart contract chains like Bitcoin and Dogecoin.
Kickstart your development with our growing examples library, with real contracts for real use cases.

Preparing for ZetaChain 1.0
With a big year coming up, ZetaChain introduces the vision for 1.0 including roadmap, token utility, ZetaHub, state of ecosystem, and how to prepare for what’s next.
ZetaChain Wrapped 2023
ZetaChain’s mission is to serve as a platform for universal access, simplicity, and utility across any blockchain. We envision a world where users can access all of their assets and data across any chain without the need for bridges or risky wrapped tokens. Developers can deploy a single contract that spans all chains, even the Bitcoin network. Building off of ZetaChain Wrapped 2022, we made huge progress towards realizing this vision. As we approach the launch of ZetaChain Mainnet, let’s look back and reflect on our top achievements of the year!
