Quotes and amounts
A buy quote takes gross USDC input and returns estimated tokens, the fee, post-trade reserve, price, market cap, and whether the trade reaches graduation. A sell quote takes token input and returns net USDC. Quotes are read from the contract through the configured Arc RPC; they are not a promise of execution.
The minimum-received value applies the selected slippage tolerance to estimated output. A transaction reverts if actual output falls below that limit before the deadline. Presets are available at 0.5%, 1%, and 2%; the custom field accepts 0.01% through 50%. Lotus converts the value to basis points and uses the displayed minimum as the transaction’s exact bound.
Approvals and settlement
Buying requires a USDC allowance for the curve. Selling requires a token allowance. Approval and trade are separate wallet transactions. Lotus waits for approval confirmation before submitting the trade and waits for the trade receipt before showing success.
Approval safety
Post-bond trading
After graduation the curve rejects further trades. When the Arc registry contains a graduated pool record, the token page uses the deployment manifest’s Uniswap v3 QuoterV2 and SwapRouter, with the user’s selected slippage supplied as the exact amountOutMinimum. If the pool record or route is absent, the interface fails closed instead of sending a curve trade.
The V4 vault and route are deployed on Arc Mainnet. The production registry is initially empty, so the canonical $50,000 lifecycle canary remains a separately tracked production-readiness check.
Candles, intervals, and empty time
Candles are the default chart style. Every OHLCV candle is built from real TradeExecuted logs in its interval. Open is the first trade, high and low are extrema, close is the last trade, and volume is the sum of real fills.
No invented candles
Confirmed candles are merged by timestamp. A shorter or temporarily empty refresh cannot delete candles already shown, and a late response for a previous token or interval is discarded. The active candle may update while new trades enter its bucket; closed candles remain stable.
On Arc, the first chart response reads the configured Blockscout explorer’s indexed TradeExecuted logs and verifies every row against the curve ABI and requested token. A raw RPC log scan remains the fallback. Short CDN and per-tab caches make repeat views immediate without hiding newly confirmed trades.
The default viewport keeps sparse launches zoomed out with surrounding context. New candles update the series without resetting a user’s horizontal zoom. Right-click inside the plot and choose Reset chart view to return to the default range and automatic price scale.
