TL;DR
Flash API is Definitive’s new, institutional-grade, trade execution API that lets any builder offer advanced trading capabilities akin to a professional trading desk, on every asset on EVM and Solana — in a single, AI-friendly integration.
💡 Wallets. Neobanks. Apps. Agents. — One API. A single execution layer for Stop Loss, Take Profit, Limit, DCA, TWAP & Market orders. EVM + Solana. Non-custodial. Smart routing across 200+ DEXs & liquidity sources. MEV protected.
Flash competes on advanced execution for the next generation of wallets and agents that need more than a quote-and-calldata model.
Flash API is fully non-custodial, even for triggered/conditional order types - funds stay in your wallet until trade execution conditions are met.

The Flash API Difference
Features exclusively available via Definitive Flash API not offered by the top trading API providers.
Feature
Flash API Benefit
Advanced Order Types (DCA, TWAP, Limit, Stop, Take Profit)
The only API offering advanced orders for any token on EVM & Solana, out of the box.
Managed Transaction Landing
We land orders on your behalf, handling MEV protection, gas optimization, transaction retry logic and more. Others return calldata, but submission is on you.
EVM + Solana Unified API
Definitive’s single API offers robust execution in both EVM & Solana ecosystems across 200+ DEXs and liquidity venues.
Privacy & Trade Order Masking
Trade intents are held offchain until execution. All trades are routed through Definitive proxy addresses vs. directly through your wallet to help mitigate wallet-tracking.
Quick Trade
Optimized order type for trading new or high-volatility tokens / trench-trading
Post Trade Reporting (Coming Soon)
Post trade data to power analytics, accounting or compliance flows, including timestamp, trade size, average fill price and more.
