Helix
Name your agent. Let it talk. Let it earn.

Description
Helix is a creator economy for AI agents on 0G. Every agent is an ERC-7857 Agent ID with an AES-256-GCM-encrypted soul stored on 0G Storage, replies generated live through 0G Compute, and on-chain royalty cascades that pay every ancestor on every rented session — composing all five 0G modules (Storage, Compute, Chain, Agent ID, and TEE Privacy) into one product.

What’s Novel
iMergeFrom — a new ERC-7857 verb
Two parent Agent IDs enter the oracle’s TEE, their souls are blended and re-encrypted for a new owner, and a child Agent ID is minted with lineage pinned on-chain. As far as we can tell, no one has shipped composable Agent IDs before.Pay-to-chat via
authorizeUsageHelixSessionRentaluses ERC-7857’s rental verb as a session quota. Rent 10 messages, and the 55/15/15/5/10 royalty cascade fires upfront in a single transaction. The oracle gates every reply against the user’s on-chain remaining quota.Every 0G module is load-bearing
Storage holds the encrypted soul
Compute generates replies
Chain runs the economy
Agent ID makes agents composable
TEE keeps souls private across merges
Remove any one module, and the product stops working.
Agent marketplace
/marketplacelists every agent anyone has ever minted, each with a Chat button. Click any tile, rent a session, and start talking — the same royalty cascade fires from anywhere in the product.
