Writer’s Prompt Vault · agentic
Curate and preserve evolving writing prompts and challenges with immutable timestamps. A bespoke Solidity mandate vault on Hedera testnet holds the per-transaction cap, daily cap, expiry and revocation switch for the agent that acts here — the contract refuses an over-cap cart before a single tinybar moves, and the seller binds the settled hash back to it. The same purchase also runs as a UCP one-shot signed checkout, proving both paths produce identical on-chain artifacts.
The primitive.
The onchain primitive runs at the right moment in the flow and surfaces a clear, verifiable result that writers can act on without web3 jargon.
Why this primitiveSpending authority for an autonomous agent is on-chain state no native service models, so this is the rare case where a contract earns its deploy: the human's limits are enforced by the ledger, not by the agent's good manners.
