Nemo

Problem Statement

Nemo is a developer tool that bridgesCoinbase’s Agent KitwithNillion’s SecretVaultto provide secure, decentralized data storage and retrieval.This tool allows developers to securely store agent-related data—such asagent names, unique IDs, API keys, and task logs—on Nillion nodes while enabling seamless retrieval for executing transactions and interacting with Coinbase APIs.Nemo ensures thatsensitive agent data is encrypted and distributedacross Nillion nodes, preventing single points of failure. Using this system, developers canmanage agent identities, retrieve API keys dynamically, and execute transactionswithout directly exposing sensitive credentials.Key Features✅Securely store & encrypt agent data(Agent Name, ID, API Key, Task Logs)✅Retrieve stored datausing simple API calls✅Integrate seamlessly with Coinbasefor transactions✅Utilize Nillion's SecretVaultfor decentralized, trustless security✅Supports both JSON-based API & CURL requestsfor flexibility
