# Pool Topology (Single-Sided PMM)

## A. Public “Edge Pools” (primary stabilization rails)

On **each public chain**, for each **cW\*** token, create **single-sided PMM pools** against the chain’s most liquid stables.

For each chain `C` and each wrapped token `T ∈ {cWUSDT, cWUSDC, cWAUSDT, cWEURC, cWEURT, cWUSDW}`:

Create pools such as:

- `T / USDC`
- `T / USDT`
- `T / DAI`
- `T / BUSD` (where relevant)
- `T / mUSD` (where relevant)

**Single-sided deposit is on the cW\*** side** (controllable inventory). The market provides the quote side via traders/arbs.

Benefits:

- Tight peg corridor around oracle price
- Arbitrage can “heal” cross-chain drifts
- Inventory-based signals for bridge flow pressure

## B. Optional “Cross-Stable Hub” Pools

To reduce quote fragmentation and pool count:

- Pick **one quote stable per chain** as the “hub” (usually USDC, or USDT on some chains).
- Deploy only `T / HUB` for each `T`.
- Rely on existing deep markets (USDC/USDT/DAI) on that chain for secondary conversion.
