Heima is a full-stack coordination protocol that abstracts complexity across accounts, chains, and agents — enabling seamless, verifiable cross-chain execution for users and developers. Through a unified omni-account system, intent-centric execution, and a decentralized Agent Hub, Heima enables users to operate across multiple blockchains without manual bridging, wallet switching, or gas token management. Its architecture leverages a custom Substrate-based Layer 1, account abstraction, omni-executor routing, and programmable automation to deliver a seamless DeFi experience rivaling CEX usability while maintaining decentralization.

How do I get Heima RPC access from Dwellir?

Dwellir runs Heima on dedicated clusters only: isolated nodes for one customer, at a monthly price. The free and shared plans do not cover Heima.

FAQs

Heima is a chain abstraction protocol that unifies accounts, chains, and execution agents, enabling cross-chain DeFi workflows through a seamless omni-account system and decentralized automation.

Heima eliminates the need for manual bridging, wallet switching, and gas token management by introducing omni-accounts and an intent-centric execution framework, allowing users to interact with multiple blockchains as if they were one.

Heima consists of four modules: the Heima Network (Layer 1 blockchain), omni-account abstraction, omni-executor for cross-chain routing, and the Agent Hub for decentralized programmable automation.

Developers can leverage Heima's programmable automation, support for on-chain and omni triggers, and EOA compatibility with EVM chains to build cross-chain dApps, wallets, and DeFi infrastructure with minimal friction.

Heima enables unified balances, gasless transactions, chain-agnostic contract interactions, and programmable automation — supporting use cases like omni-chain DEXs, wallets, GameFi automation, and intent-driven dApps.
