AMMs and DeFi Summer

A market made from inventory

An automated market maker replaces a traditional order book with a rule relating the assets in a pool. Anyone can trade against inventory, and liquidity providers receive fees. The contract makes a continuous quote possible without matching a named buyer and seller. That is a real institutional innovation, not merely a different screen.

The curve does not create value

The pool’s formula reallocates assets as prices move; it does not know the external price or protect a provider from ending with a less valuable mix than simple holding. Arbitrageurs align the pool with other markets and collect the difference. The apparent automation therefore depends on actors and prices outside the contract.

Liquidity mining changes the question

In DeFi Summer, governance tokens subsidized deposits and created extraordinary yields. Those yields mixed trading fees, token issuance, speculative appreciation, and sometimes rights over a protocol. One percentage on a dashboard could combine income with dilution and risk. Calling it all “yield” hid who was paying whom.

Automation has a political edge

Contracts can apply the same formula to every address. People still choose parameters, fee switches, upgrades, token distributions, and emergency actions. AMMs removed a particular market intermediary. They did not remove governance or unequal information; they relocated both to code ownership, token concentration, and the interfaces through which users saw the pool.
