How Definitive uses Privy to deliver best-in-class security and seamless onboarding to power a next-gen trading experience

Decentralized exchanges (DEXs) now process $10B+ in trades every day, and they’re gaining ground fast. In Q2 2025, DEX volume jumped 25% while centralized exchange (CEX) volume fell nearly 30%. Today, a record 1 in 4 spot crypto trades happen onchain on DEXs, according to CoinGecko.
Despite this momentum, the trading experience onchain can remain fragmented and frustrating. Users bounce between chains, interfaces, and wallets, and have to wrestle with gas fees and potentially failed or delayed transactions. Advanced order types like time-weighted average price (TWAP), stop loss, or limit orders, which are features traders take for granted in centralized platforms, are also harder to access on DEXs while preserving a seamless user flow.
The result is a trading experience that falls short of user expectations, limiting the pace of adoption even as onchain volumes scale rapidly.
Definitive, a trading platform designed to deliver CEX-level execution on DEX rails, set out to change this.
Definitive was built to deliver the kind of trading experience users expect from the best centralized exchanges, without sacrificing the openness of DeFi. The result is a multichain trading platform that brings advanced execution, seamless UX, and gasless flows together in one place.
Definitive provides:
Advanced trading on every chain: Definitive supports Market, Limit, Stop Loss, Take Profit, and TWAP orders, unlocking precise trading actions that have long been missing from DEXs.
Institutional-grade tech, built for the masses: With pre-simulated quoting and algorithm-optimized routing, Definitive ensures users always get best execution and deeper liquidity, no matter the chain.
Multichain by design: Built for both EVM chains and Solana, Definitive integrates native bridging and cross-chain swaps so traders never have to leave the platform.
Gasless trading: Network fees are abstracted away, making every trade frictionless across chains.
CEX-like experience, onchain: By combining an intuitive interface with one-click orders that don’t require repetitive approvals, Definitive delivers a trading flow that feels on par with centralized platforms, while staying fully onchain.
And the results speak for themselves. Institutional investors like Starkiller and BlockFills are using Definitive because it gives them efficient access to assets that would otherwise be impractical on CeFi or OTC desks. At the same time, the identity behind the trades they make is protected, and market impact is minimized.
To deliver a seamless, CEX-like experience onchain, Definitive needed infrastructure that could combine simple onboarding, strong security, and powerful wallet capabilities.
By building on Privy, Definitive benefits from:
All-in-one infra that includes authentication, wallet connectors, and embedded wallets through a single integration
Drop-in UI components that streamline account creation, login, and external wallet connections
Passkey support that delivers best-in-class security
Fine-grained policy controls that enable advanced capabilities, like session signers and time-bound permissions, giving Definitive the flexibility to evolve their product over time
Hands-on support from the Privy team that keeps engineering velocity high
Definitive isn’t stopping here. The team is preparing to launch a retail-focused trading experience alongside a new version of their mobile app in Q4 of 2025, which is designed to bring the platform’s powerful infrastructure to an even wider audience.
This next chapter will introduce their fastest trade execution yet. It will also be paired with instant onboarding, customizable discovery, and new growth mechanics that directly reward Definitive users.
As Definitive continues to scale, Privy remains committed to supporting their journey — providing the underlying wallet infrastructure on a secure foundation that is needed to power seamless, gasless, and truly accessible onchain trading at global scale.
