An AI Agent for crypto wallet workflows: chat, analyze, transact, and accept fiat payments without forcing users through complex wallet menus.
Nova AI Wallet is not a new wallet and not just a chatbot. It is an agentic wallet orchestration layer that sits on top of existing wallets such as MetaMask and WalletConnect-compatible EVM wallets. The agent understands user intent, chooses the right tool, fetches real wallet/on-chain/payment data, prepares safe next actions, and leaves final transaction signing to the connected wallet.
The product is Lisk-first, while the codebase already explores a broader multi-chain experience across Ethereum, Mantle, Polygon, Optimism, Arbitrum, Base, and testnets.
Nova AI Wallet was recognized in the SEA Lisk Builders Challenge 3 and won two categories:
- 1st Notable Mention - SEA Lisk Builders Challenge 3
- 1st Social Media Challenge
Nova was developed as an AI agent because it can reason over user intent, call tools, use external data, and prepare actions with guardrails. It is designed around an agent loop:
flowchart TD
A["Natural-language user prompt"] --> B["Intent understanding"]
B --> C["Tool / action selection"]
C --> D["Live wallet, on-chain, payment, or cost data"]
D --> E["Smart response, card, or form"]
E --> F["User confirmation"]
F --> G["Wallet signing / payment flow"]
Agent capabilities implemented in this repository:
- Intent understanding: maps natural-language prompts into wallet actions such as balance checks, transfers, swaps, and analysis.
- Tool use: calls balance, portfolio, token activity, whale activity, counterparty, payment, and cost prediction tools.
- Live data grounding: fetches blockchain, wallet, payment, and price/cost data before answering.
- Generative UI: returns smart cards, forms, and transaction previews instead of only plain text.
- Human-in-the-loop safety: prepares transactions but never signs or executes without explicit wallet confirmation.
Implementation evidence:
| Agent capability | Evidence in code |
|---|---|
| Intent parser | app/lib/intentParser.ts |
| CopilotKit tool/actions layer | app/chat/actions/useNovaActions.tsx |
| Manual LLM tool-calling route | app/api/ai/chat/route.ts |
| Copilot runtime endpoint | app/api/copilotkit/route.ts |
| On-chain analysis tools | app/lib/blockchainAgentWrapper.ts, app/lib/blockchain/aggregators |
| Wallet and transaction UX | app/chat/page.tsx, app/components/chat |
| Fiat-to-crypto payment tools | app/lib/services/payment.service.ts, app/lib/services/midtrans.service.ts, app/lib/services/transak.service.ts |
Most crypto wallets still assume users already understand networks, gas, addresses, bridges, explorers, token approvals, and transaction previews. Nova turns those workflows into natural-language conversations.
The core problem:
- Wallet interfaces are too manual. Even simple tasks like checking a balance or sending funds require several screens.
- Addresses are hard to trust. A raw
0x...address tells users almost nothing before they send money. - On-chain data is powerful but unreadable. Users jump between explorers, dashboards, and price tools just to answer one question.
- Transaction costs are unclear. Gas, route quality, fees, and slippage often appear too late.
- Crypto payments are still hard for non-crypto clients. Freelancers can receive crypto, but clients may only want to pay with fiat rails.
Nova's answer is simple: an AI agent first, smart cards second, wallet signing only after explicit confirmation.
Users can ask Nova to check balances, explain concepts, prepare transactions, or analyze wallet activity in plain language. Nova behaves like a crypto workflow agent: it chooses the right action, fetches the required data, and returns a safe next step.
Example prompts:
Cek saldo aku di Mantle SepoliaAnalyze address 0xd8dA...Kirim 0.01 ETH ke 0x...Berapa gas yang sudah aku habiskan?
Nova parses intent, calls the right data source or action, then renders a readable response or an embedded transaction card.
Nova helps users understand wallet behavior, not just raw balances.
Supported analysis areas in the current codebase:
- Native token balance checks
- Portfolio overview
- Token activity and P&L style summaries
- Transaction statistics
- Whale activity detection
- Counterparty and interaction analysis
Nova includes an execution-cost prediction flow for trade cost, slippage, and exchange comparison. The companion API documentation lives in api.md.
Use cases:
- Estimate real execution cost before a trade
- Compare venues such as Binance, Kraken, Coinbase, and OKX
- Explain slippage and fees in user-friendly language
Nova Paylink lets freelancers and creators generate a payment link where clients pay in fiat and the receiver gets crypto.
Payment rails:
- Indonesia: QRIS via Midtrans
- Global: Card/on-ramp flow via Transak
Example prompt:
Buat paylink 0.1 ETH
Nova opens a payment form, creates the payment request, and shows a payment status card.
Nova uses a chat-first agent architecture where the AI layer chooses the right action, fetches real blockchain or payment data, and returns a human-readable answer or UI card.
How the flow works:
- User prompt: The user asks a natural-language question or command.
- Agent reasoning: Nova classifies intent and decides which capability is needed.
- Tool/API call: The agent fetches wallet, chain, payment, or prediction data.
- Smart response: Nova renders the result as chat text, cards, forms, or transaction previews.
- Human approval: Transactions are never executed without explicit user confirmation through the connected wallet.
- Frontend: Next.js App Router, React, Tailwind CSS, Radix UI, shadcn-style components
- Wallet: Wagmi, Viem, RainbowKit, WalletConnect
- AI Agent: CopilotKit actions, Gemini-based tool-calling route, custom intent parsing, generative UI cards
- Blockchain: RPC reads, Etherscan/Blockscout-style clients, custom on-chain aggregators
- Payments: Prisma, PostgreSQL, Midtrans QRIS, Transak
- Utilities: Zod, Axios, Upstash rate limiting, Recharts

Nova is being shaped into an AI agent wallet experience: first as a chat-to-action interface, then as an intelligence layer, and eventually as an automation layer for crypto workflows.
The project includes early usability framing and beta testing references in the product documentation.

Nova's strongest product direction is:
An AI Agent for users who want to understand and act on crypto without opening five different tools first.
The most important next polish areas are payment reliability, clearer production/demo separation, faster on-chain analysis, and tighter README/demo assets.
