Abstract

April 2026 · Stellar Mainnet

StellarNotherc introduces a payment-native financial agent that integrates artificial intelligence, on-chain payments, and zero-knowledge proofs into a unified execution framework.

Unlike conventional AI systems that operate as non-economic agents, StellarNotherc embeds financial accountability directly into the agent's decision loop. Users allocate a fixed budget in XLM on the Stellar blockchain and interact with the agent through natural language. The agent interprets user intent, selects appropriate tools from a priced marketplace, and executes transactions on-chain to acquire those services.

Each paid action is accompanied by a zero-knowledge proof generated using SP1 zkVM. These proofs cryptographically attest to the integrity of every transaction—including the tool identity, payment amount, and execution correctness—without exposing sensitive information such as private keys. This mechanism removes the need to trust the agent's internal behavior, shifting trust to verifiable computation.

The system architecture separates concerns across three layers: a frontend orchestration layer handling user interaction and session lifecycle, a worker layer responsible for analytics and tool execution, and a cryptographic proof layer ensuring verifiable financial integrity. This design enables modular extensibility across use cases such as portfolio analysis and cross-border remittance.

StellarNotherc demonstrates a new paradigm for AI systems as economic actors, where every action carries a measurable cost and is subject to cryptographic verification. While current proofs guarantee execution integrity, future work may extend toward partial verification of decision optimality, bridging the gap between probabilistic intelligence and deterministic trust.

Trust Model

  • On-chain Stellar payments are the authoritative record of every purchase and settlement.
  • SP1 proofs are informational attestations—they do not gate tool output delivery.
  • The user wallet signs the final remittance transaction; the agent wallet never holds custody beyond the session budget.
  • Session aggregate proofs allow third-party auditors to verify the full session without replaying it.
