Crypto Paper Trading: Practice First, Then Let an AI Agent Trade Small
Moby has no paper trading mode. When you go live, fund the agent wallet with a small amount of USDC and set a max per trade, a daily buy limit and a market-cap range in the Moby app. Moby checks those limits on every buy.
What paper trading is, and what it misses
Paper trading is practice with simulated money. You place orders and watch a balance that is not cash you can withdraw. People use it to learn a screen, a bot, or a set of rules before a live order.
A paper fill often skips what a live swap does. Slippage moves the price between the quote and the fill. Fees come out of the trade. A live order can fill in part, or not fill. A losing trade on a demo balance does not feel like a losing trade with money you funded. Treat a clean paper result as practice, then decide the size you can lose before any live swap.
Ways to paper trade
Some exchanges publish a demo mode with a simulated balance. Read that exchange's own help page for which markets the demo covers and what a demo fill skips.
Alpaca's MCP server README, read on November 11, 2026, says you create a free paper trading account, and that ALPACA_PAPER_TRADE defaults to true. Set it to false for live trading. The same README says the paper trading API does not require real money. That mode is Alpaca's. It is not a Moby mode, and this page does not claim it paper-trades Solana tokens. The comparison is on Moby vs Alpaca MCP.
A backtest is a different check. It replays rules on prices that already happened. Moby does not run backtests. How to do that with an assistant, and the traps to look for, is on backtesting with AI.
Go live small with an agent
When you trade with a Moby agent, the orders are live. Start with a small amount of USDC in the agent wallet. In the Moby app, set three limits: max per trade, daily buy limit and market-cap range. Moby checks them server-side on every buy. Leave Ask before every trade on, so a buy waits for your yes. Moby refuses agent buys on red-rated tokens, and a refusal is final. There is no transfer tool. The agent cannot withdraw or send funds.
Agent trading is Solana only. The agent wallet is funded in USDC. How the three limits fit a wider set of rules is on AI agent guardrails and AI trading risk management. What changes when an agent can trade is on let AI trade for you.

Fees
A 0.75% swap fee (minimum $0.90 per swap), plus onchain fees. Put that fee in any practice test you run elsewhere. A result that ignores it is not the swap you would place.
FAQ
Does Moby have paper trading?
No. Moby has no paper trading mode. A swap from a Moby agent uses the USDC in the agent wallet.
Can an AI agent paper trade crypto?
Only when the product it connects to has a paper or demo mode. Moby has no paper trading mode, so a Moby agent places live swaps. Alpaca's MCP server README, read on November 11, 2026, says ALPACA_PAPER_TRADE defaults to true and that you can create a free paper trading account. That paper mode is Alpaca's, not Moby's. A backtest on past prices is a separate check, and Moby does not run one.
What does paper trading miss?
Slippage, fees, how a live order fills, and how a losing trade feels. A simulated fill can look cleaner than a live swap on Solana.
