Bypassing the bank: How to set up a direct-to-custody payroll DCA

Description and use

The author explains how to set up a direct‑to‑custody payroll DCA, eliminating bank intermediaries, reducing fees, and automating the process with safety rules.

Problem

Monthly salary is routed through multiple intermediaries, incurring fees, delays, and risk of bank censorship, making dollar‑cost averaging (DCA) inefficient and error‑prone.

Outcome

The workflow eliminates bank‑related friction, reduces fees from 1.5–3% to near zero, and automates the entire DCA process, allowing the author to keep 10–15% of each paycheck in Bitcoin and cold storage without manual intervention.

Workflow

• 1. Verify employer payroll supports split direct deposits (e.g., Gusto, ADP, Workday).
• 2. Allocate a percentage (e.g., 10%) of paycheck to a secondary bank account or directly to a crypto exchange that accepts direct deposits (Coinbase in the US, Coinmate in Europe).
• 3. Set up an automated buy on the exchange using the deposited fiat (via direct deposit or standing order).
• 4. Use API keys with only trade permissions to trigger the purchase and immediately sweep the Bitcoin to a hardware wallet (e.g., Trezor).
• 5. Apply the author’s three rules: keep allocation ≤10–15%, consolidate UTXOs by sweeping only when a threshold (≥$500–$1,000) is reached, and never store withdrawal‑permitted API keys on third‑party servers.

Evidence

Every month, my salary used to take a scenic route. It went from my employer's bank, to my bank, to a crypto exchange, and finally—if I didn't get lazy or greedy—into my hardware wallet.

I once had a bank block a perfectly legal transfer to an exchange for "security reasons," forcing me to spend 45 minutes on the phone with customer service explaining that yes, I actually wanted to buy Bitcoin with my own money.

When you get paid, your money sits idle. If you use a standard recurring buy on a major retail app, you're likely paying 1.5% to 3% in convenience fees.

First, you need to check if your employer's payroll system supports split direct deposits. Most modern platforms like Gusto, ADP, or Workday allow you to split your paycheck by percentage or dollar amount across multiple bank accounts.

Once the fiat lands on the exchange, the magic happens. You don't want the cash sitting there. You want an automated system to execute the buy and immediately sweep the funds to your custody.

The 10% threshold: Never allocate more than 10-15% of your paycheck directly to this automated pipeline.
