Your balance earns 4% APY by default through Instant-access investing, our anytime-withdrawal investment account. If you’d prefer not to use Instant-access investing, you can disable it from your Accounts page (under Accounts detail).

Disabling Instant-access investing means your money will remain with Prime Trust, our accredited US custodian, who will store your funds across multiple insured bank accounts to an aggregate limit of $130,000,000. You will be able to withdraw uninvested funds at anytime for free, but you won’t earn any interest on your balance.

We currently support ACH transfers for linked US accounts up to $5,000 per transaction, and wire transfers which are unlimited.

In the interest of security, we’re in the process of moving all cash management to our custodial partner, Prime Trust. This means in the future we won’t need to handle your funds at all.

However, we’re somewhat limited by the deposit methods Prime Trust accept, and it’s likely Zelle will be phased out in the next few months.
