# Smart Contract API

Integration of smart contracts into legacy systems or other applications can be a difficult task if done the first time. This is why we created the ONINO Smart Contract API - a simple way for any developer to integrate smart contract interaction within their systems.

API wallets are used in the ONINO backend to interact with your deployed smart contracts. To get started and explore the API quickly, you can create a testnet wallet with one click. For production use, you can securely import an AWS KMS wallet.

API keys are used to authenticate your application with the API and allow you to interact with your deployed smart contracts using your API wallets. Below you can create and manage your API keys.
