VOOI is a non-custodial trading terminal aggregating spot, perpetual, and real-world asset markets across major blockchains. The challenge: users' funds are fragmented across chains, and the best markets are spread across marketplaces. VOOI integrated OneBalance to handle cross-chain execution, turning trading across any marketplace into a simple one-click experience.
The result: weekly trading volume peaked at $3.2B, volume per user grew 3-5x, and the platform now supports 100,000+ active users who can trade any market onchain with one click.
The challenge: Liquidity is everywhere, but users are not
VOOI’s v1 proved demand, but scaling across chains exposed a constraint: every new market and network increased operational complexity and added steps to the trading workflow. The result was higher drop-off and slower trading whenever users needed to move across chains or venues. This showed up in five ways:
- Fragmented liquidity: the best opportunities were spread across venues, and timing mattered.
- User drop-off: slow, multi-step deposit and trading flows reduced conversion and retention.
- Operational overhead: bridging, network switching, gas handling, and edge cases increased failure points and support burden.
- Gas management: each network required its own native gas token, adding another prerequisite before a trade could be placed.
- Split balances: funds were scattered across chains, limiting users’ ability to deploy their full portfolio when trading.
VOOI’s v1 validated demand, driving billions in order flow. But to scale, they needed a unified experience where cross-chain complexity stayed behind the scenes. That became the foundation for v2, built with OneBalance.
The solution: OneBalance for a unified, non-custodial trading experience
VOOI's v2 turned their vision into reality, becoming a unified trading terminal that allows users to trade across every supported marketplace, chain, and market using a single stablecoin balance.
To make that possible, VOOI integrated OneBalance's APIs to handle the underlying blockchain complexity and cross-chain execution, removing it entirely from the user experience.
In practice, this means:
- Any market, one balance: Stablecoin balances (e.g. USDC or USDT) are unified into a single balance, even if split across multiple chains and venues.
- Deposit once, trade everywhere: Funds deposited from any major EVM chain or Solana are available for trading immediately, without manual bridging between networks.
- Trade without managing gas: Gas fees are paid in the asset being traded, so users never need to hold separate native gas tokens.
- CEX simplicity, built on blockchain rails: VOOI’s user experience feels akin to a centralized exchange, with instant execution, and no blockchain complexity for users, while remaining fully non-custodial.
Expand to new chains without rebuilding: VOOI can add new chains and marketplaces without any additional operational overhead or redesigning the user experience each time, saving time for every new integration.
The results: From $200M to $3.2B in weekly volume
Since launching v2 with OneBalance on July 1, VOOI hit a series of measurable milestones:
- $25B+ in total trading volume.
- New all-time highs across every timeframe: $429M peak daily volume, $3.2B peak weekly volume.
- 100,000+ new active users.
- Added 5+ chains, including non‑EVM networks like Solana.
- Expanded to 4 new marketplaces, without any additional operational overhead.
The biggest unlock came from removing the barriers that caused users to drop off. By turning cross-chain complexity into a centralised exchange-like experience, while remaining fully non-custodial, VOOI was able to:
- Turn one-time depositors into active traders: Post-V2 user activity shifted from event-driven spikes to a sustained daily baseline.
- Drive ~10x growth in weekly volume: Pre-V2 weekly volumes rarely exceeded $200M; post-V2 weeks consistently scaled past $2B.
- Increase volume per user by 3-5x: Average lifetime volume per user grew from an estimated $25-40k pre-V2 to around $132k post-V2.
What this means for teams building a non-custodial trading product
OneBalance is proud to work with VOOI as they expand across chains and marketplaces. VOOI’s v2 shows that cross-chain execution can operate at scale, processing billions of dollars in cross-chain volume without imposing multichain complexity on users, while delivering an experience that keeps users coming back.
Under the hood, OneBalance provides high‑throughput, reliable onchain execution infrastructure. Powered by our DvP‑like model, we make cross‑chain settlement predictable and consistent at scale. If you’re integrating digital assets or stablecoins into your product, we can provide the institutional-grade execution infrastructure to help reduce friction, improve conversion rates, and grow volume.
