+title: Deploy VELODROME and S to Perps V3 Base
+network: Base
+status: Vote_Pending
+type: Governance
+created: 2025-01-23
+author: Kaleb
+---
+
+# Simple Summary
+
+This SCCP proposes to deploy the below markets on Perps V3 on Base:
+
+| **Market** | **minimumInitialMarginRatio** | **initialMarginRatio** | **maintenanceMarginScalar** | **skewScale** | **maxMarketValue** | **maxMarketSize** |
+|:----------:|:-----------------------------:|:----------------------:|:---------------------------:|:-------------:|:------------------:|:-----------------:|
+|      S     |             5.00%             |          1.159         |            0.317            |   12,000,000  |      1,000,000     |     3,000,000     |
+|  Velodrome |             5.00%             |          0.437         |            0.317            |   12,000,000  |       300,000      |     6,000,000     |
+
+Aside from the above parameters , the perps markets will have the following configurations as well:
+- TakerFeeRatio: 10 bp 
+- MakerFeeRatio: 2 bp
+- maxFundingVelocity: 36
+- flagRewardRatio: 3 bp
+- minimumPositionMargin: 15
+- lockedOiRatio: 0.1
+- maxLiquidationLimitMultiplier: 1.5
+- maxLiquidationPD: 5 bp
+- endorsedLiquidator: "0x11233749514Ab8d00C0A5873DF7428b3db70030f"
+
+
+# Abstract
+
+The parameters configurations description is as follows:
+- initialMarginRatio is a scalar applied on the minimumInitialMarginRatio to determine the minimum initial margin required to support a given portfolio of positions
+- maintenanceMarginScalar is a scalar applied on the initialMargin in order to obtain the maintenanceMargin. When traders fall below the maintenance margin, they are liquidated.
+- skewScale is the scaling factor of the relevant market in the underlying currency for computing price impact and funding rates
+- maxMarketSize is the max market value of the relevant market in the underlying currency
+- maxMarketValue is the max market value of the relevant market in USD
+- maker/taker fees pertain to fees charged when trading
+- maxFundingVelocity is the main parameter that allows to nudge funding rates
+- minimumPositionMargin is the minimum margin required
+- lockedOiRatio is the multiplier that determines the minimum amount of perp collateral required to back a given perp market
+- maxLiquidationLimitMultiplier is a parameter that rate limits liquidations. It is applied on the sum of maker and taker fees with a liquidation rate limit being triggered if pd exceeds that value
+- maxLiquidationPD is the minimum pd that triggers a reset of the liquidation capacity
+- endorsedLiquidator is a liquidator address that can bypass the rate limit
+- the collateral liquidation penalty is the penalty paid to the liquidator for executing a liquidation
+
+
+# Motivation
+
+The more options traders have via Synthetix Perps, the less likely they will move their margin to other trading venues to trade markets we don't provide.

+title: Enable sUSDC As Margin
+network: Base
+status: Vote_Pending
+type: Governance
+created: 2025-01-23
+author: Kaleb
+---
+
+# Simple Summary
+
+Currently the base deploy allows for the below margins to be used as margin:
+- snxUSD
+- scbBTC
+- scbETH
+- sWETH
+- swstETH
+
+This sccp proposes to add the ability to use sUSDC as margin on base.
+
+# Abstract
+
+The main configurations of this margin are as follows:
+- maxCollateralAmount: 100m$
+- synth_usdc_upper_limit_discount: 0
+- synth_usdc_lower_limit_discount: 0
+- synth_usdc_discount_scalar: 1
+
+With the above configuration the margin would have no discount imposed.
+
+# Motivation
+
+This was requested by a partner integrator who wishes to use sUSDC for margining in order to avoid having the procure snxUSD via a buy/sell in their implementation. Note that snxUSD can be swapped into sUSDC and back without any fees atomically at parity on base, but using sUSDC can facilitate the onboarding as the implementation would not need to buy snxUSD when adding as margin. Nevertheless, the integrator would still have to deal with snx, as that is the only margin accepted to settle outstanding debt in order to withdraw a margin.
