Moby vs Griffain: Solana AI Agent Trading Compared
Moby and Griffain both let an AI agent act on Solana. Griffain's Agent Engine runs agents in its own app, with a wallet you unlock and energy you buy. A Moby Agent trades Solana spot from its own wallet, funded in USDC, and the Moby app checks limits on every buy.
Who each is for
- Griffain if you want to build a custom agent in Agent Studio, upload sources, pick actions, and share a link so people use that agent inside Griffain.
- Moby if you want one agent that trades Solana spot from USDC, with buy limits checked in the Moby app, from the hosts Moby documents.
They can sit next to each other. Each product has its own wallet and its own account.
Side-by-side
Checked November 6, 2026 against Griffain's docs at pricing, energy, wallets, build an agent, exchanges, and getting started. Those pages change. Read them again before you fund a wallet.
| Dimension | Griffain | Moby Agent |
|---|---|---|
| What it is | The Agent Engine. Agents run in the Griffain interface. A public share link lets someone open your agent. | One hosted agent per user, with its own Solana wallet, connected from the hosts below. |
| Custody | A Griffain wallet, locked until you unlock it. Unlocking grants agents permission to sign and send. Locking revokes that. The wallet doc says Privy manages the keys, and that you can export the private key. | One agent wallet, separate from the main in-app wallet. The agent cannot withdraw or send funds. |
| Limits | The pages checked here describe energy, gating, and a wallet you can lock. They do not describe a server-side cap on trade size. | You set your agent's limits on max per trade, daily buy volume and market-cap range from the Moby app, and Moby checks them server-side on every buy your agent makes. Moby refuses agent buys on red-rated tokens. |
| What the agent can do | Agent Studio actions include answering from uploaded sources, onchain transactions such as swaps, mints, or deposits, and fetching data. Tasks can repeat on an interval. | Research and Solana spot trading through Moby MCP, inside the limits above. Tell your agent your exits and it places real take-profit and stop-loss orders on Moby, including a one-call bracket. |
| Hosts | Agents run in the Griffain UI. The build guide says you share a public link. It does not list Codex, Claude Code, or Grok CLI as hosts. | Codex, Claude Code (CLI), Gemini CLI (with a paid Gemini API key or enterprise access) and Grok CLI with the agent key. In ChatGPT, paste your personal Moby connector URL from the app. ChatGPT: works on Business, Enterprise and Edu workspaces that allow custom MCP servers (web). |
| Exchanges | The exchanges page says Griffain supports trading on Robinhood Crypto and Backpack Exchange. A linked account lets agents get account information, view order history, and manage holdings. | Solana spot only, funded in USDC, including tokenized stocks. Agent trading on Base, BNB Chain and Robinhood Chain is coming soon. Moby Agents do not trade perps. |
| Who can use a custom agent | Optional gates: a token, an NFT, a minimum SOL balance, or a verified email. A creator can sponsor energy so users are not charged. | Your own agent, tied to your Moby account. There is no public share link for a second person's agent. |
| Fees | A one-time 1 SOL fee to initialize a custom agent. Energy is priced at $1 each on the pricing page, and at 1 USDC each on the getting-started page, with a 10 Energy minimum. Energy expires 1 year after purchase and is non-refundable. Transactions are 0.0015 SOL each, plus 1% of the SOL amount when the transaction is a trade. | A 0.75% swap fee (minimum $0.90 per swap), plus onchain fees. |
When to pick which
Pick Griffain when the job is a custom agent for a product or protocol: uploaded sources, chosen actions, gates, and a link you can post. Pick Moby when the job is Solana spot trading from USDC, with buy limits the app enforces, from Codex, Claude Code (CLI), Gemini CLI (with a paid Gemini API key or enterprise access) and Grok CLI with the agent key. In ChatGPT, paste your personal Moby connector URL from the app. ChatGPT: works on Business, Enterprise and Edu workspaces that allow custom MCP servers (web).
