On-chain proof
Verify the cold storage
Every quarter, the accumulated daily buys are moved from Cash App into a Bitkey hardware wallet. The integrated Cash App → Bitkey transfer creates a new receiving address each time, so the cold storage lives across several addresses. All of them are listed below. Balances are fetched live from the Bitcoin network via mempool.space — click any address or transaction to check it yourself.

Sweeps happen at the end of each quarter (Mar / Jun / Sep / Dec). Between sweeps, the most recent daily buys sit in Cash App until the next transfer, so the on-chain total lags the “$ stacked” count by design. New addresses are appended here after each sweep confirms.
