The problem MeNabung solves
The Silent Crisis of Saving
In Indonesia, saving money the traditional way feels like fighting a losing battle. With inflation at 2.9% and bank interest stuck at 0.4%, keeping money in a bank account means you are literally paying for the privilege of losing value.
We all know DeFi has the answer, yields of 5% to 15%, but actually accessing it is terrifying for normal people. I tried explaining "liquidity pools" and "impermanent loss" to my friends, and I saw them give up immediately. The existing tools don't help either; they are just chatbots giving generic textbook advice like "diversify your portfolio," without knowing if you have $10 or $10,000.
MeNabung bridges this gap.
We built a "wallet-aware" AI on Base. It doesn't just chat; it reads your on-chain IDRX balance, profiles your risk, and executes the strategy for you. It turns a complex, 10-step DeFi process into a simple, safe conversation, allowing everyday Indonesians to beat inflation without needing a degree in finance.
Challenges I ran into
The "Blind Advisor" Problem
The biggest hurdle wasn't the smart contracts, it was the AI's context. In our first build, the AI was "blind." A user would ask, "How much should I deposit?" and the AI would give a generic Wikipedia-style answer like "Financial experts recommend 20%..." It was frustrating because it felt robotic.
The Fix: We realized we couldn't just use a standard LLM call. We had to build a dynamic WalletContext system. We essentially "incepted" the system prompt with live on-chain data (User Balance: 978 IDRX, Current Vault APY: 12%) before the user even sent their first message. Suddenly, the AI went from a generic chatbot to a personalized advisor that said, "You have 978 IDRX sitting idle; let's put that to work."
The IDRX Decimal Trap
This one gave us a mini heart attack. We are used to working with ETH (18 decimals) or USDC (6 decimals). IDRX uses 2 decimals.
During our first integration test, the dashboard showed users having millions of dollars in savings because the math was off by a factor of 10^16. It was a mess.
The Fix: We had to audit every single line of our frontend code. We implemented a strict utility function that checks the token contract's decimals before doing any formatting. No assumptions allowed.
Making "Let's Go" Actually Work
We noticed a funny UX issue: users would chat with the AI, get excited, and type "Okay, let's do it!"... and nothing would happen. The strategy card wouldn't pop up because our code was strictly looking for a number (e.g., "Deposit 500").
The Fix: We wrote a detectActionIntent() function. Now, if the AI detects strong intent keywords (like "ready," "let's go," or "invest"), it assumes the user wants to deposit their current liquid balance and triggers the transaction UI automatically. It made the experience feel 10x more magical.
