  • Safe multisigStablecoins and native tokens on six networks, signed to your threshold.

Payments from a Universal Account or a Safe wait for your approval rules first, and a wallet payment can go through the same rules. How approval rules work

Built to see

  • Banks through PlaidBalances, history, and their own receiving details.
  • Addresses you watchBalances, and an address to be paid at.
  • ExchangesBalances, through a key that can't move a thing.
  • Custodians and anything elseAdded by hand, so they still count in your totals.
