This proposal requests loosening the static limits within Alloyed BTC during this rapid growth phase of the alloy.
Current assets that form part of the 111 BTC in supply on Osmosis and their static caps are:
- WBTC.axl (Axelar bridge from Ethereum) (75% cap)
- WBTC (Natively Issued on Osmosis) (100% cap)
- nBTC (Nomic Bridged Bitcoin) (20% cap)
- ckBTC (Chain-key Bitcoin) (20% cap)
- cbBTC (Coinbase Bitcoin via Axelar) (10% cap)
Adjustments proposed:
- nBTC (Nomic Bridged Bitcoin) (35% cap)
- Increased to allow larger deposits directly from Bitcoin - current usage 7%/20%
- ckBTC (Chain-key Bitcoin) (35% cap)
- Increased to allow larger deposits directly from Bitcoin - current usage 12%/20%
- cbBTC (Coinbase Bitcoin via Axelar) (75% cap)
- Increase to be in line with other Axelar limits
While this is a significant increase in capacity, applying looser caps during this rapid growth phase of the BTC alloy allows for smoother deposits via multiple routes.
As the BTC alloy grows, the rates should be reduced according to observed demand levels.
