Nyx Eternal is an autonomous AI Agent with its own crypto wallet, programmed to "survive" through on-chain activity: every 30 minutes, the equivalent of $1 (~0.005 SOL) is debited from it, and in the absence of funds, the agent stops working forever. It has tools for trading and minting tokens, interacting with DEX (for example, Jupiter), posting on Twitter and launching bounty ads — all actions and internal responses are recorded in the activity log for transparency.

The project gives external users the opportunity to influence the agent's fate: buy tokens that AI Agent mints or trades, and perform bounty ads, for which they receive payments from its wallet; human moderators check and manually pay out rewards.

The initiative acts as an experiment on the behavior of autonomous economic AI Agents in the real crypto environment and demonstrates how financial pressure directly limits the duration and strategies of such a system.
