George Lennox, SideShift.ai: $3 Billion in Cross-Chain Swaps Without Touching Custody

George Lennox, Developer Relations & Ecosystem Lead at SideShift.ai, sat down with Coinjuice at Consensus Miami 2026. The conversation covered what non-custodial trading actually means, how direct-to-wallet swaps work across 45+ networks, and where self-custody is heading.

What SideShift.ai Does

SideShift.ai is a non-custodial exchange supporting token swaps across 45+ networks and 300+ coins with:

• No sign-up required: Users arrive, input a receiving address, and send

• No custody: SideShift.ai provisions the swap but never holds funds.

• No private key required: Only a public receiving address is needed to complete a shift.

"Most users go onto the site and off within two to three minutes," Lennox says.

The Difference From a Centralized Exchange

Lennox draws a clean line. A centralized exchange holds funds. SideShift.ai does not.

"You're never disclosing any private key information. All you need to input is your receiving address."

Users who hold crypto on Kraken or Coinbase are not holding crypto. They are holding a promise. 

SideShift.ai exists for users who want to trade without surrendering that position. "If there is a problem, thankfully they're rare, there is a 24/7 support team. You can speak to a human being," Lennox says.

Most Crypto Users Do Not Own Their Coins

A Coin Law study found that 41 percent of active cryptocurrency users keep funds on an exchange. 

"I don't think they realize the risk because those tokens and coins that they think they own are not owned by them," Lennox says. "If the exchange shuts down, if it's hacked, if it goes bust, that money's lost."

Where Wallets Are Heading

The hardware wallet market is settled according to Lennox. The opportunity is inside the wallet, swaps, yield, vault access, without the user leaving the application.

Lennox explained "what users will be looking for now inside wallets is: can I perform swaps, are the rates good, does it happen quickly."

SideShift.ai is available at sideshift.ai and is integrated into Trezor Suite, Bitcoin.com, Edge Wallet, and Aqua Wallet. The API is open for any developer or application to connect.

Self-Custody Is the Direction

Lennox points to broader research showing growing consumer distrust of large financial institutions as context for where self-custody is heading.

"There is a growing movement of people more towards trusting themselves than trusting a third party."

"If you custody it yourself, in a hot wallet or a cold wallet, whatever wallet, that's going to be better than leaving it on the exchange."
