Robinhood Chain support refers to the blockchain. MemeTag does not connect to a Robinhood brokerage account or place stock orders in the Robinhood app.
Routing depends on the token, available pools, amount, and network conditions. Not every listed token or pool has an executable route.
What a trade costs
MemeTag adds no platform fee in extension version 1.4.8. Other costs still apply.
| Cost | How it applies |
|---|---|
| Pool and route fees | Included in the selected route’s quote. |
| PumpPortal fallback | 0.5% local-route fee plus applicable pool and network costs when used. |
| Network transaction fee | Paid to the relevant network; failed transactions may still incur fees. |
| Solana account rent | An account-creation deposit may be needed for a token or temporary account. |
| ERC-20 approvals | Separate transactions may consume ETH before the swap. |
The order shows a minimum output and a maximum reserve for network costs and, where applicable, account rent. Unused reserve remains in the wallet. The swap minimum does not describe the total change across every wallet balance.
Network connections
The default endpoints are Vibe Station for Solana and PublicNode for Robinhood Chain. They work without entering an API key. Requests to the shared Solana endpoint are paced; public providers can still apply limits. You can choose your own HTTPS mainnet endpoints in Settings; the browser requests permission to connect to each chosen host.
MemeTag checks the Solana mainnet genesis hash or Robinhood Chain ID before preparing relevant network actions. An endpoint must support the account reads, simulations, transaction submission, and status queries the route needs.
Your RPC provider can see network requests and your IP address. Read Privacy for the data sent to outside services.
Route limitations
Some transfer-tax tokens, Token-2022 extensions, transfer hooks, unsupported pools, and routes that need multiple transactions may be rejected. A route being discoverable does not mean it will execute.
A simulation checks a proposed transaction at a point in time. Prices, liquidity, or network conditions may change before confirmation.
