Acorns for your crypto wallet on Base. Auto save the spare change from any incoming ERC-20 payment into cbBTC. For example, if you receive $1.50 in USDC on Base, then $0.50 gets set aside in a spare change pot. Once your pot hits your chosen threshold, it auto-swaps to cbBTC. Tiny transfers below your desired minimum are ignored, so dust and spam payments don't clutter your savings.
