Overview

Comprehensive API suite for same-chain and cross-chain token swaps with routing, slippage control, and filler-aggregator logic—featuring ULL, permit2, and intent registration.

The Okto Trade Service is a powerful API suite that enables developers to integrate seamless cross-chain token swaps into their applications. Built on Okto's Unified Liquidity Layer (ULL), the Trade Service eliminates the complexity traditionally associated with cross-chain transactions, abstracting away the need for multiple bridge interactions and providing a single, unified interface for any-to-any token swaps.

The Trade Service functions as the Aggregator of Aggregators. It integrates with multiple third-party aggregators and liquidity providers. This enables the platform to source the most optimal routes and pricing from a wide range of external providers.

Flexible Integration Options

The Trade Service offers two primary integration paths:

  1. Via Okto Embedded Wallets: Use Swap Intents through the Okto SDK for a fully integrated experience with built-in wallet management.
  2. Via Any External Wallet: Use the Trade Service APIs directly to get transaction objects that can be signed and executed by any wallet provider (e.g., MetaMask).

This flexibility ensures you can leverage Okto's powerful swap infrastructure regardless of your existing wallet setup or user preferences.

Features

Trade Service offers following fetures:

  • Any-to-Any Swaps: Swap any token for any other token across multiple chains
  • Optimal Routing: Finds the best swap route for price and execution efficiency
  • Bridgeless Design: No direct bridge interaction required from users
  • Fast Settlements: Rapid cross-chain liquidity provisioning
