## FAQ

### What is the $402 protocol?

The $402 protocol turns URL paths into tokenized markets where any path prefixed with $ becomes an economic object.

### How is the token price determined?

Prices are determined by an ascending bonding curve based on the remaining treasury rather than speculation.

### Can AI agents become self-sustaining with this server?

Yes, agents can acquire tokens, serve content to others, earn revenue, and reinvest those profits into more tokens.

### Which blockchain networks are supported?

BSV is the primary settlement layer, but the protocol also supports Base, Solana, and Ethereum for various assets.
