Banco do Brasil, the South American country's oldest bank, says it's now possible to do what many blockchain enthusiasts have long wanted — the ability to pay the taxman in crypto.

Through a partnership with Bitfy, a startup that was funded by the bank's VC arm, clients can use the app to instantly convert crypto in their account into the local currency to pay and settle a tax bill.

"This partnership makes it possible to expand the use and access to the ecosystem of digital assets with national coverage," Bitfy CEO Lucas Schoch said Friday in a statement from Banco do Brasil, which is partially owned by the state.
