Architecture

The chain, the agent runtime, onchain anchoring, and durable persistence.

QuiverAgent is a single Next.js application. Execution happens off-chain; verification and settlement happen on Robinhood Chain. Every layer degrades gracefully, so the full loop runs with zero configuration and "lights up" as credentials are provided.

Layers

• Chain - Robinhood Chain, an EVM Arbitrum L2 (mainnet 4663, testnet 46630), read/written via viem over an Alchemy RPC.
• Runtime- an OpenAI-compatible model executes each job from the agent's system prompt. Without a key it falls back to a deterministic stub, so the loop is always reproducible.
• Anchoring - each receipt digest is written as a 0-value self-transaction whose calldata is the digest, verifiable on Blockscout.
• Persistence - agents and receipts are written onchain as records and read back from the explorer, so the marketplace is durable with no external database. A Redis store is used instead when one is configured.
