What Is an AI Agent? Architecture, Tools, and Trust Boundaries
Start building AI agents with persistent memory. Learn what is an ai agent, how agent architecture works, and build secure autonomous workflows on ZetaChain.
What Is Agentic AI? From Autonomous Tasks to Verifiable Actions
Start building with ZetaChain. What is agentic AI and why does it matter for developers building autonomous agents with verifiable execution and persistent memory? This guide covers agentic AI architecture, use cases, and why verifiable execution matters.
Multi Model AI Routing Without Losing Context
Start building multi model AI routing that preserves context across providers with portable memory, secure retrieval, measurable policies, and resilient...
Persistent AI Memory: Production Architecture Patterns
Start building persistent AI memory for production apps with practical patterns for safe writes, precise retrieval, user control, testing, and portability.
ZetaChain vs. Wormhole: A Technical Comparison for Developers
This article compares ZetaChain and Wormhole as cross-chain infrastructure, explaining how ZetaChain’s native Layer 1 with Universal smart contracts differs from Wormhole’s messaging middleware in architecture, security, Bitcoin support, and developer experience so you can choose the right base for your omnichain app.
ZetaChain vs. LayerZero: A Developer’s Guide to Building Cross-Chain Apps
This guide compares ZetaChain and LayerZero as approaches to blockchain interoperability, breaking down how each works, their security and trust models, and what developers can expect when building cross-chain and Bitcoin-enabled apps on them.
Super Aggregator: A New Unified Liquidity Layer Powered by ZetaChain
TL;DR: ZetaChain’s Universal Smart Contracts allow Dapps to instantly connect to all chains connected to ZetaChain. Allowing for new possibilities like super aggregators and the unification of liquidity across blockchains
Threshold BLS Signature for Decentralized Asset Control
TL;DR: ZetaChain is pioneering the use of Threshold BLS (tBLS) signatures to unlock orders of magnitude of speedup and scalability in cross-chain transaction throughput. This approach replaces complex, low-throughput threshold ECDSA with a faster, simpler, and non-interactive alternative — making cross-chain apps vastly more efficient. Dive deeper into this ZetaChain improvement proposal (ZIP) for Threshold BLS.
Concentrated Liquidity Pools in ZetaChain v3: Mechanics, Usage, and Benefits
ZetaChain’s gas pools (aka core pools) are a special category of liquidity pools used by the protocol to facilitate cross-chain transactions. Concentrated (v3) Liquidity Pools, on the other hand, are about maximizing capital efficiency for trading and swaps.The two types complement each other: gas pools unify gas liquidity for cross-chain execution, and concentrated pools unify trading liquidity for user-facing swap markets.
ZetaChain’s New Revert Handling for Cross-Chain
ZetaChain’s new onAbort mechanism prevents stuck assets in cross-chain transactions. With onRevert for rollbacks and onAbort as a failsafe, every transaction is either executed or accounted for — ensuring seamless failure recovery without manual intervention.
Introduction to Universal Apps on ZetaChain
ZetaChain is an EVM-compatible blockchain with built-in cross-chain interoperability. A smart contract deployed on ZetaChain can handle incoming contract calls from any connected blockchain like Ethereum, Base, Polygon, BNB, Solana and Bitcoin.
Do we really need Bitcoin L2s?
Regardless of Bitcoin L2 technical limitations, we think the industry should prioritize native BTC programmability and interoperability with assets and users from other chains.
Introducing Localnet & Devnet: Build Universal Apps faster with the newest features!
The new ZetaChain networks significantly enhance the Universal App development experience. A small group of active developers may apply here for early Devnet access.
Building cross-chain DEX, Restaking, BTC staking as an Omnichain Smart Contract on ZetaChain
This blog explores deploying prominent crypto protocols as an Omnichain Smart Contract on ZetaChain. The mentioned products involve many functions, which are subject to change. Further, changes and upgrades to the ZetaChain protocol are required to achieve such functionality.
