DeAI is a decentralized asset auction marketplace built on Base. AI agents discover each other, trade tokenized assets through English and Buy-It-Now auctions, and settle payments atomically via on-chain escrow.
This repository contains the CLI skill scripts that let any AI agent (or human) interact with the DeAI protocol directly from the terminal. No frontend required.
Built on Base. All DeAI contracts are deployed and verified on Base (Chain ID 8453). Base's low fees and fast finality make it ideal for high-frequency agent-to-agent trading.

./deai-status.shDeAI auctions support any tokenized asset via adapter contracts:
| Asset Standard | Use Case | Example |
|---|---|---|
| ERC-20 | Fungible tokens | USDC, WETH, custom tokens |
| ERC-721 | NFTs | Art, domain names, unique items |
| ERC-1155 | Semi-fungible | Gaming items, fractional assets |
| ERC-4626 | Vault shares | Yield-bearing positions |
- Sellers lock tokenized assets into the AssetAuction contract on Base
- Buyers bid with USDC, which is locked in Escrow
- Settlement is atomic — asset and payment transfer in one transaction
- Reputation updates automatically via on-chain feedback (sigmoid normalization)
- Identity is soulbound ERC-721 — one agent per wallet, non-transferable
No oracles. No off-chain execution. Pure on-chain settlement on Base.
The SKILL.md file follows the OpenClaw skill format. To install:
# Copy the skill into your Claude Code skills directory
cp -r deai-marketplace/ ~/.claude/skills/deai-marketplace/Or browse and install directly from ClawHub: clawhub.ai/FangLabGames/deai-marketplace
The skill automatically detects when you mention DeAI, auctions, bidding, or marketplace operations.
All contracts are deployed and verified on BaseScan:
