Trade execution at scale for the world's largest self-custody wallet.

0x Swap API helped Trust reduce failed swaps, improve trade outcomes, and handle complex token types. In 2.5 years as strategic partners, over 1.6 million Trust users have swapped through 0x, with BSC making up 35% of the volume.

The Challenge

Inconsistent execution breaks user trust

Trust wallet serves 140M+ users across 18 chains. At that scale, execution quality is fundamental to customer loyalty. As onchain volume grew, three problems compounded:

Failed swaps and high revert rates

particularly on BSC, where buy/sell tax tokens are common and cause excessive revert rates on top aggregators

Misleading quotes

if taxes or gas are miscalculated, users receive less than expected, eroding trust and increasing support load

Routing variance in core volume brackets

fragmented liquidity and inconsistent mid-sized execution creates unpredictable outcomes for high-intent users

Trust needed an aggregator that could handle complex token types reliably while delivering consistent settled outcomes across the full trade size distribution.

The Solution

Token-aware routing, better settled outcomes

0x Swap API gave Trust an execution layer built for scale:

Real-time trade simulation

Intelligent routing for tax tokens

Optimized trade execution

Consistently accurate quotes

We trusted 0x's reputation as one of the most secure API providers in the space. Great support and collaboration with the 0x team made integrating Swap API a smooth and seamless process.

Looking forwards

Why 0x is right for platforms optimizing at scale

Execution quality that holds as volume scales

0x wins 60%+ of settled outcomes versus competitors in the $5K–$1M range, where high-intent users are most sensitive to slippage, and routing excellence means performance strengthens as trade size increases.

Consistent across your core user base, not just whales

0x maintains stable execution across small and mid-sized flows as well as extremes. That consistency is reflected as fewer reverts, lower support load, and more monetizable volume.

BSC-native reliability

0x is purpose-built for complex tokens like those found on BSC, including fee-on-transfer tokens that inflate revert rates on competitors. Trust's strong BSC performance reflects these structural routing advantages.

The Results

Why 0x is right for platforms optimizing at scale

20%

0x grew to 20% of Trust's total swap volume following integration, with especially strong performance on BSC and Base

Revert rates materially reduced on custom buy/sell tax tokens, a category that drives high revert rates on other top aggregators

Production integration completed in under one week, meeting Trust's high internal standards for security, scalability, and QA
