Otim SDK provides a complete toolkit for integrating Otim’s smart automation capabilities into your app. Built with TypeScript-first design, the SDK offers intuitive APIs for authentication, delegation, instruction building, and activation.

​
Key Features

  • SIWE Authentication – Sign In With Ethereum for Secure EOA Delegation.
  • Instruction Builder – Type-safe APIs for transfers, swaps, sweeps, and refuels.
  • Configuration Data – Chain support, token lists, and fee estimation.
  • Universal Module Support – CommonJS and ES modules for any JavaScript environment.

​
Architecture

The Otim ecosystem is composed of clearly defined layers. The SDK represents the client layer running inside your application and orchestrates communication with off-chain services and on-chain smart contracts.
  • Client Layer (Your App using Otim SDK). Runs in browser, Node.js, or React Native apps. Handles authentication, instruction building, and signing.
  • Off-chain Services (API & Executor). The API receives the signed instructions from the SDK. A backend Executor service then monitors the blockchain for the instruction’s specific conditions. When conditions are met, it submits the transaction to the network to be executed.
  • On-chain Protocol (Smart Contracts). A set of audited smart contracts (OtimDelegate, InstructionStorage, ActionManager) forms the trustless execution layer. They validate the incoming transaction from the Executor, manage the instruction’s state, and call the appropriate Action contract (e.g., for a transfer or swap) to complete the user’s request.
