Bridge manages the underlying reserves backing your stablecoin to ensure it is always at least 100% collateralized with equivalent fiat value, as well as to optimize rewards. As a developer, you have the flexibility to choose how the reserves backing a custom stablecoin are split between liquid assets and treasuries. 
  • Liquid: Reserves allocated to liquid assets such as fiat and stablecoins available for rapid redemptions to all of Bridge’s supported currencies, but earn a lower rewards rate than treasuries.
  • Treasuries: Reserves allocated to treasuries earn maximum rewards, and can be redeemed within 1 business day. Bridge will manage the distribution among our custodians to optimize earnings and redemption speed.
You configure your allocation and Bridge manages directly with our custodians.

​
Choosing Your Reserve Allocation

When issuing a stablecoin with Bridge, you can choose to allocate reserves between USD, stablecoins*, and treasuries. Each asset has their own redemption and reward profiles, see the table below for more information. There are 2 key choices you need to make to set your reserves:
  1. Percentage of reserves to be held in on-demand assets versus treasuries
  2. Of the on-demand assets, how you want to distribute them between USD for instant business hours liquidity versus in stablecoins* for 24/7 and instant on-chain liquidity
    1. You can select both a percentage distribution and a minimum
    2. If both on-demand balances are below their respective minimums, reserve allocations will be rebalanced accordingly
After these choices are made, Bridge will allocate the remaining percentage of reserves to treasuries.   This allocation can be changed at any time to balance needs across rapid redemption and reward generation.
