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.

Configuration: ../config/pool-matrix.json, ../config/chains.json.
