AI & Code Generation

Overview

At the heart of SynthFi is a purpose-built AI engine that turns plain-language prompts into real, deployable smart contracts on Solana, using the Anchor framework.

This section explains how SynthFi's AI layer works, what it produces, and how we ensure the code is accurate, readable, and safe to use.

How It Works

1. You enter a natural language prompt (e.g., “create a staking contract with 30-day lock and 10% APR”)

2. The prompt is parsed and interpreted by a large language model (LLM), customized for DeFi + Solana logic

3. The AI generates:

   • A complete smart contract (lib.rs) written in Rust + Anchor

   • Supporting files like Cargo.toml, instruction definitions, and account layouts

   • Optional program constraints (PDAs, access control, time locks)

   • A matching React frontend with wallet connect + contract interaction UI

4. You can then send the generated code to the Launchpad to prepare for deployment and review

What the AI Produces

Output	Description
Smart Contract	Anchor program including instructions, accounts, events, constraints
IDL (optional)	JSON interface used to connect frontend to contract
Frontend DApp	Next.js + Tailwind React app wired to Phantom Wallet
Launchpad Draft	Bundled metadata, ready to preview, configure, and deploy

---

Supported Logic (Current)

• Token staking (APR or fixed)

• Time-locked vaults (with penalties or unlock schedules)

• Vesting contracts (linear, cliff)

• Admin-controlled reward pools

• Custom access roles (via has_one, signer, or PDA authorities)

• Reward claiming or airdrop contracts (in progress)

---

AI Design Goals

• ✅ Readable, modifiable Anchor code

• ✅ Predictable structure (init/stake/withdraw patterns)

• ✅ Compatibility with Phantom and Solana Devnet

• ✅ Generation transparency — you see and own your code

---

Limitations

While SynthFi generates high-quality starter contracts, it's not a replacement for:

• Full audits

• Complex composability (multi-program CPIs, DAO logic)

• Mainnet-ready production code without developer review

You should always review the generated logic before deploy.

---

Risk Flagging

After generation, SynthFi performs a risk scan on the contract to flag common dangers like:

• Withdrawals only callable by admin

• Locked funds with no release function

• Improper signer checks on close_account

• Hardcoded authorities

These warnings are shown in the Launchpad UI before allowing deployment (or in simulated flow).

Coming Soon

• GPT-powered function-by-function audit notes

• Prompt templates with guided examples (staking, vesting, airdrop, DAO)

• Contract explanations ("Explain what this contract does in plain English")

• Prompt feedback scoring (clarity, risk, precision)
