Seamlessly bridge your institutional liquidity with automated onchain execution by integrating Coinbase Business with B3OS Wallet. Automate high-volume crypto transfers, manage payment links, and trigger secure, wallet-signed transactions through a single, unified workflow engine.
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. ### Quick Setup: 1. Import your wallet or use your B3OS Treasury Wallet 2. Pick the Base tokens you want to round down 3. Set a minimum - transfers under this amount are ignored, so dust and spam don't clutter your savings 4. Test and publish!
