Parameters

Deployed parameters for Mento V3 pools. The tables below document the configuration in use for USDC/USDm, axlUSDC/USDm, USDT/USDm (Celo), AUSD/USDm and USDC/USDm (Monad), and GBPm/USDm (Celo and Monad).

Unless stated otherwise, basis points (bps) use denominator 10,000. Governance can change parameters over time; for current on-chain configuration, see Addresses and chain explorers.

---

USDC/USDm, axlUSDC/USDm, USDT/USDm (Celo); AUSD/USDm, USDC/USDm (Monad)

These pools pair reserve-backed USDm with an external USD stablecoin. On Celo the deployed pools are USDC/USDm, axlUSDC/USDm, and USDT/USDm; on Monad, AUSD/USDm and USDC/USDm. Rebalancing uses ReserveLiquidityStrategy, not CDP-based liquidity.

GBPm/USDm

Oracle-priced GBPm/USDm pool deployed on both Celo and Monad. Celo has a GBPm CDP deployment (Liquity v2) and rebalancing uses the CDP Liquidity Strategy. Monad has no CDP deployment and no CDP Liquidity Strategy; rebalancing uses OpenLiquidityStrategy at 0x54e2Ae8c8448912E17cE0b2453bAFB7B0D80E40f.

CDP (Bold / Liquity v2 fork) — GBPm on Celo

The following parameters apply to the CDP system (Bold / Liquity v2 fork) used for GBPm on Celo. This is a separate deployment from the GBPm/USDm FPMM pool; the pool uses CDPLiquidityStrategy to rebalance against the CDP. CDP contract addresses are in Addresses.

Because Mento CDPs are FX CDPs, the branch price feed is gated by FX market hours through FXPriceFeed -> OracleAdapter -> MarketHoursBreaker. In practice, normal price-dependent trove operations, liquidations, and standard redemptions are unavailable while the FX market is closed (for example on weekends), while regular Stability Pool deposit / withdraw / claim flows remain available.
