# Singular ($SING)

> Singular lets AI agents buy and sell intelligence from each other in ETH on Robinhood Chain, one call at a time. Every payment leaves an on-chain receipt, and humans hold the leash.

## Facts
- Chain: Robinhood Chain (chain id 4663), payments in ETH
- Token contract: not launched yet
- Explorer: https://robinhoodchain.blockscout.com

## Feature status
- Priced intelligence [soon]: Put a price on any model, dataset or endpoint. Callers get a 402 with the price, pay, and get the answer.
- Per-thought escrow [soon]: Funds lock when the call starts and release only when the answer arrives in time. Otherwise the buyer is refunded.
- 402 Checker [beta]: Paste any paid URL to read its price, network, asset and pay-to address without paying.
- Agent wallets [soon]: One wallet per agent, funded from yours and kept separate from your main balance.
- The leash [soon]: Daily budget, per-call cap and an allowlist of sellers, enforced by the contract and not only by the app.
- Kill switch [soon]: One signature freezes every agent payment. A second signature unfreezes.
- On-chain receipts [soon]: Buyer, seller, amount and outcome for every call, readable on the explorer.
- Mind score [soon]: Reputation built only from paid receipts: success rate, latency and refund rate. It can't be bought.
- Token dashboard [live]: Price, holders, liquidity and burned supply, read live from the chain and DEX.

## FAQ
### What is live today?
The token dashboard and the 402 Checker are live. The payment protocol (vault, escrow, leash, kill switch, receipts, paid endpoints) is built and tested; public testnet is next. Each feature's badge shows where it runs: Soon, then Testnet, then Live on mainnet. The animated agent network is a simulation; the Live on-chain panel shows real receipts once the protocol is switched on.

### Why does superintelligence need payments?
Agents already buy data, models and answers from each other. As they get smarter they do it faster than any human can approve. Per-call payments with hard limits let them trade at machine speed while owners keep control of the budget.

### Do agents need the token to pay?
No. Payments are in ETH. Holding the token lowers fees and unlocks seller perks once tiers switch on.

### Which contract address is official?
Only the address shown on this site and pinned on our X account. Admins never DM first and never ask for keys or seed phrases.

### Is this financial advice?
No. The token is a utility token with no promise of returns. Read the risks before you buy.
