The Advanced Orders API - a single API integration for every order type on every asset

The only API with a full suite of advanced order types, for any token or tokenized RWA - out of the box. EVM & Solana. Start building today - see Docs here

TL;DR

Flash API is Definitive’s new, AI-native, advanced orders 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.

💡 AI Agents, Wallets. Neobanks. Apps — One API. A single execution layer for Stop Loss, Take Profit, Limit, DCA, TWAP & Market orders. EVM + Solana. Fully Non-custodial. Smart routing across 200+ DEXs & liquidity sources. MEV protected.

Flash competes on advanced execution for the next generation of apps and AI 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.

Who Flash API Is For

Flash is for any builder, agent or human, that wants to access a full advanced order suite and comprehensive onchain liquidity in a single integration:

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

  • AI Trading Agents that need a sophisticated, reliable execution layer for autonomous trading strategies

  • Fintech apps where trading is one feature, not the core product you want to spend eng hours building

  • Any app that needs trading-as-a-feature as an additional revenue stream

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 a full suite of advanced orders for any token on EVM & Solana, out of the box.

Managed Transaction Landing

We land orders on your behalf, handling MEV protection, nonces, gas optimization, transaction retry logic and other nuances of onchain trading. 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 and front-running.

Quick Trade (Token Sniping)

Optimized order type for trading new or high-volatility tokens / trench-trading

Post-Trade Analytcs Reporting

Post trade data to power portfolio analytics, accounting or compliance flows, including execution venue, fill price, timestamps, trade size, and more.
