Flash API (coming May 2026)

Integrate Definitive's advanced trading into your wallet, trading agent, or app with a few lines of agent-friendly code

TL;DR

Flash API is Definitive’s new, institutional-grade, trade execution API that lets any wallet, app, or AI agent offer advanced onchain trading — without building it themselves.

💡 Wallets. Exchanges. Apps. Agents. — One API. Single execution layer for Stop Loss, Take Profit, Limit, TWAP, Quick Trade & Market orders. EVM + Solana. Non-custodial. Smart routing for 200+ DEXs & MMs. MEV protected.

Flash competes on advanced execution for the next generation of wallets and agents that need more than a quote-and-calldata model.

Unlike our Existing Client API, Flash API does not require you to deposit into Definitive’s trading vault wallet infrastructure.

Who Flash API Is For

• Crypto wallets looking to add advanced order types (TWAP, Limit, Stop, Take Profit, Quick Trade) as an additional revenue stream without a 6+ month engineering sprint

• AI Trading Agents that need a simple, reliable execution layer for autonomous trades on EVM + Solana

• Embedded wallet apps where trading is one feature, not a core product you want to spend 6+ months building

• Fintech and neobanks that need onchain trading-as-a-feature as an additional revenue stream or differentiator
