# On-Chain, Cross-Chain Execution

_Execution Doesn’t Leave the Chain — Even When It Moves Across Them_



Z4R0 agents don’t rely on backend jobs, off-chain logic, or centralized scripts. Every action — whether it's a swap, stake, or capital move — is enforced by smart contracts and fully recorded on-chain. If a strategy executes, it’s because the contract allows it. If conditions aren’t met, nothing happens. There’s no off-switch, no hidden relay, and no “bot behind the scenes.”



But this execution power isn’t limited to one chain. With LayerZero and IBC integration, agents can operate natively across the Ethereum mainnet and Layer 2s like Arbitrum, zkSync, and Optimism. Agents can observe liquidity on one chain, transmit a proof-bound execution intent, and trigger capital movement on another — all governed by the same on-chain rules and without off-chain relays. You get multi-chain reach, without off-chain compromise.
