TL;DR: By integrating Zerion API’s tokens endpoint, Bungee reduced 3–4 second token load times, expanded token coverage beyond the top 1000, and simplified infrastructure, delivering a smoother user experience and freeing developer time.
When building a seamless bridging experience, every detail matters, especially how tokens show up in a user’s profile. Bungee Exchange is an Open Liquidity Marketplace built on SOCKET Protocol that delivers chain-abstracted swaps through permissionless agents. For them, slow token balances were more than just an annoyance. This added friction at the very first step of the user journey.
To solve this, Bungee turned to Zerion API’s multichain tokens endpoint. The result was faster token discovery and a smoother experience for every Bungee user profile.
What is Bungee?
Bungee is an Open Liquidity Marketplace that makes moving assets between blockchains simple, fast, and reliable. Instead of users needing to compare multiple DEXes or bridges, Bungee provides the best routes to the user.
Bungee gives its users access to seamless swaps and bridging across dozens of networks. For end users, this means less time juggling different tools and more confidence that their transfers will just work.
Bungee has become a core part of the user experience in the increasingly multichain world. Token visibility plays a crucial role in making swapping frictionless.
The Challenge: Showing All Tokens Users Have
For Bungee, the swapping experience begins with a simple question: does the user see all their tokens right away? But making that happen wasn’t simple.
The team’s initial approach combined RPC calls for each chain with Coingecko’s token lists. While workable, it came with two major drawbacks:
- Slow load times — token balances could take up to 3–4 seconds to appear, creating noticeable friction.
- Limited coverage — only the top ~1000 tokens per network were supported, leaving out many long-tail and newer “exotic” tokens.
This meant users sometimes had to wait, refresh, or wonder why certain tokens didn’t show up at all. For a product built around a seamless cross-chain experience, even small points of friction risked undermining trust in the overall experience.
The Solution: Zerion API’s Multichain Tokens Endpoint
To remove latency and expand token coverage, the Bungee team integrated Zerion API’s multichain tokens endpoint into their user profiles.
Given an EVM wallet address, Zerion API fetches all token positions across 26+ chains with a single call. The positions are enriched with token metadata and real-time prices.
Instead of juggling CoinGecko lists and custom RPC calls, the integration provided:
- Instant token discovery — balances load with a P99 latency of 2 seconds, a noticeable improvement over the 3–4 second delay.
- Comprehensive coverage — beyond the top 1,000, including even the most exotic tokens across all networks.
- Fallback flexibility — Zerion API became the default option, with existing methods remaining as backup if needed.
With one integration, Bungee delivered a smoother, more reliable profile experience while reducing the overhead of maintaining custom token listing logic.
The Impact: Better UX for Swaps
Integrating Zerion API transformed the way token balances appear in Bungee user profiles.
For end users, the change was immediate and contributed to greater conversions into swaps through:
- Faster token lists in profiles — token balances now load without noticeable delay.
- No ‘invisible’ tokens — even niche or exotic tokens show up, removing confusion and missed opportunities.
For the Bungee team, the benefits went beyond UX:
- Reduced infrastructure complexity — no need to maintain custom token lists or juggle multiple providers.
- Developer focus — freed up engineering time to work on core bridging features rather than blockchain plumbing.
By removing these small but significant friction points, the team ensured that Bungee’s swapping experience felt seamless from the first click.
“With Zerion API, we no longer worry about token coverage or slow load times. Token lists just work, and our team can stay focused on building the core chain abstraction experience.” — Dimitri Golecko, Product Manager at Bungee Exchange.
Time to Build
By switching from custom token lists to Zerion API, Bungee solved two key problems at once: slow token loading and incomplete coverage. The result was a smoother user experience, faster token lists, and less infrastructure complexity for the team.
For a fast-moving product like Bungee, the speed of implementation mattered. It meant less time spent on infrastructure and more focused on delivering a smooth, reliable bridging experience.
