Spark is back at it again, giving a live lesson on risk management to all the DeFi protocols. On April 1st, wBTC was re-added to Spark's collateral list. Since it's a wrapped Bitcoin, Spark set a deposit cap of 3,000 wBTC. So far, 2,741 have been used. As the cap nears its limit, the system has activated an automatic quota management mechanism, adding up to 500 wBTC every 12 hours, gradually increasing the cap based on demand. In contrast, many lending protocols, including AAVE, previously added a ton of wrapped tokens and altcoins to their collateral lists all at once, often without any limits, leading to repeated disasters. Spark's restraint demonstrates the principle of 'less is more, slow is fast.' #DeFi #RiskManagement #wBTC
