# MetaDAO AMM migration reduces state rent costs from 135-225 SOL annually to near-zero

MetaDAO's migration from OpenBook to a custom AMM is projected to reduce state rent costs from 135-225 SOL annually (36-60 proposals at 3.75 SOL each) to approximately 3.75 SOL annually (for a single liquidity pool). The cost reduction comes from replacing per-proposal OpenBook markets (which require separate order books and state accounts) with a single AMM pool that can serve all proposals.

## Evidence

From the proposal's cost analysis:
> "Currently, we spend ~3.75 SOL per proposal on state rent for OpenBook markets. If we have 36 proposals per year, that's 135 SOL per year. If we have 60 proposals per year, that's 225 SOL per year. With an AMM, we would only need to pay state rent for the AMM itself, which would be almost nothing."

The proposal contrasts this with the 30 SOL development cost:
> "This is a one-time cost, and it will save us a lot of money in the long run."

## Limitations

- The 3.75 SOL per-proposal figure and "almost nothing" AMM cost are unverified estimates from the proposer, not measured data from deployed systems
- Actual costs will depend on the final AMM implementation and Solana's state rent pricing
- The cost comparison assumes similar functionality between OpenBook markets and the AMM
- Does not account for potential additional costs (monitoring, maintenance, upgrades) of custom AMM infrastructure
