Crypto products often lose money not during the initial API integration but afterward, when users encounter missing assets, worse rates, or failed transactions. According to data from ChangeNOW, the real cost comes from users leaving for competitors or turning into support tickets. The exchange's business API, supporting over 1,500 coins across 110+ networks, aims to plug those leaks.
The four loss points
ChangeNOW identifies four main places where products bleed users after launch. Missing assets top the list — every token, network, or pair that isn't available gives a competitor a chance to establish a new habit. Fiat on-ramp barriers are next: if users have to leave the product to buy crypto elsewhere, many won't come back. Worse rates and slow execution give users time to compare alternatives, and liquidity depth directly affects both price and reliability. Finally, failed transactions — wrong network, missing memo, or other errors — shift users from revenue flow to support costs, reducing repeat activity.
Why post-launch performance matters
The size of the initial feature list matters less than what happens after the API goes live. A product can launch with hundreds of pairs, but if users can't find the asset they want or the swap fails, they'll go elsewhere. ChangeNOW's data suggests that post-launch performance — not the launch itself — determines whether a product retains users or bleeds them.
ChangeNOW's approach
ChangeNOW's business API covers over 2.25 million pairs, with all assets inter-exchangeable. It sources liquidity from both centralized and decentralized exchanges, supports fixed-rate and standard-rate swaps, and reports 99.99% availability with a 350 ms API response time. The company also provides 24/7 support, a personal manager, and assistance with recoverable exchange issues — aiming to turn failed transactions into resolved ones rather than lost users.
Metrics that keep users from churning
ChangeNOW tracks several post-launch measures to catch problems early: the share of asset or network searches that return no route, quote-to-completion conversion rates, fiat purchase completion rates, transaction exception rates, and repeat activity after a failure. The idea is to spot a leak before it becomes a habit for users to go elsewhere. For products integrating crypto, the difference between a successful launch and a costly one often comes down to what happens after the first swap.
