Inside ChangeNOW’s Trading Engine: How It Makes Crypto Swaps Look Easy

Crypto swaps look dead simple on ChangeNOW. Pick two tokens, send one, receive the other. Usually done in minutes across 110+ blockchains. But what’s underneath?

A trading engine that acts as middleman between you and the exchanges — executing trades from its own liquidity so customers never touch order books or fees.

Pauline Shangett, ChangeNOW’s CSO, explains it plainly: “We mostly operate in our own liquidity when it comes to swaps.” The platform prices trades off exchange order books, market-data feeds, and an in-house liquidity engine of wallets holding balances for specific pairs. Running off its own reserves means network congestion isn’t as big a liability.

Swapzone benchmarked 150,000 transactions and found ChangeNOW’s median USDT-to-ETH settlement clocked in under a minute. Industry median? About 45 minutes.

Fiat support runs through Transak, Simplex, Banxa, and Guardarian — Visa, MasterCard, Google Pay, Apple Pay, all in.

New features include private transfers that hide sender wallet addresses from recipients (while keeping AML monitoring), a Permanent Exchange Address for recurring conversions, crypto payment links, and a prediction markets hub tracking Polymarket, Kalshi, and Robinhood markets.

Demand shocks get managed by geography. The team spans time zones and pre-positions inventory. “We get extra liquidity for that particular token for when American users wake up,” Shangett said.

Support runs four deep: community team on social, chat and email tickets, then escalation to L2 and L3 engineers on call 24/7. The platform’s got a 4.6 Trustpilot rating off over 13,000 reviews.

Simple on the surface. Not so simple underneath.
