Lighter review

Matching follows price-time priority and executes at the maker price. A crossing order takes liquidity; a non-crossing limit can rest. Unlike an AMM curve, available levels and order arrival determine the process.

Post-only cancels an order that would become taker. It controls execution role, but may leave you without the intended trade. Reduce-only restricts execution towards zero exposure, helping prevent an exit order from reversing the position. Neither feature guarantees an execution price.

Regular Standard pricing covers both spot and perpetuals, but they serve different goals. Spot buys assets; perpetuals maintain collateralised exposure. Up/Down binary options are a third product with another fee formula and should not be budgeted using perpetual maker/taker pricing.

A regular Standard order on 1,000 units of notional has no maker/taker execution charge. Buying and immediately selling can still lose value through spread or changing prices. Zero execution fees do not guarantee an unchanged balance.

Advanced Standard, TWAP and RFQ orders cost 1 basis point, or 0.01%. That is 0.10 USDT on a hypothetical 1,000 USDT fill. Spreading execution over time can serve a strategy without guaranteeing a better average price.

Optional Plus costs 0.5 basis points, or 0.005%, on maker and taker execution: 0.05 USDT on 1,000 USDT. It is an account choice, not simply another name for a volume tier. Do not carry Standard’s zero rate into its calculation.

Premium without LIT is 0.0040% maker and 0.0280% taker, or 0.04 and 0.28 USDT on 1,000 USDT. Staking 1,000 LIT gives a 2.5% discount, resulting in 0.0039% and 0.0273%. The 30% discount at 500,000 LIT is not ordinary pricing for every user. Consider token capital and price exposure before pursuing a reduction.

Standard documents 300 ms taker and cancellation/modification latency, versus 0 ms maker latency. This is a service condition, not a guarantee of end-to-end time from your device. Network connection and market conditions still matter.

Standard supports up to four subaccounts, which cannot be deleted. Plus supports sixteen with higher API limits; Premium documents 140 ms taker latency. Identify the actual constraint before paying for another account. More capacity is not useful merely because it exists.

API account management and transaction submission have defined limits. An integration should distinguish submitting a request from a completed trade. Retrying without checking state can duplicate an intention. Automated execution still needs balance, sizing and outstanding-order checks.

Binary option fees depend on size and P × (1 − P), with P representing price. The collected Up/Down terms show maximum maker zero and maximum taker 1%. Applying that maximum as a flat perpetual rate ignores the formula.

A binary position is neither spot ownership nor the same exposure as a funded perpetual. Choose the payoff you need before assessing its charges. The existence of another product does not automatically improve a simple token-swap use case.

Account tier does not determine the correct deposit route. Follow the asset, network and destination presented by the application. A bridge or associated liquidity product does not by itself establish the funding network for every trading account.

For funds coming from a centralised exchange, match its withdrawal route to the destination and retain network-cost balance. The transfer guide separates sender, blockchain and receiver. Once credited, keep capital available for margin or a planned exit rather than allocating everything automatically.

Before withdrawing, review exposure, pending orders and free balance. Disconnecting does not close a perpetual. No flat withdrawal or fixed funding rate is invented here; these inputs belong to the concrete transaction, outside Standard’s maker/taker zero.

Lighter describes SNARK proofs of price-time matching. This relates to order execution rather than a guarantee covering every contract, permission or external tool. Limit capital per strategy and understand an integration’s authority.

Keep recovery independent of the interface and review granted permissions. If subaccounts separate strategies, also record the tool controlling each one. The security guide provides useful habits, while DEX signatures require attention beyond a device password.

Hyperliquid supplies another spot/perpetual book with volume tiers and HYPE discounts. Aster combines zero perpetual maker with market-specific taker categories. Compare equivalent orders and notional rather than each platform’s cheapest unrelated figure.

For centralised account tools, see Bybit. For another spot buying route, consider Kraken. Lighter is most compelling when regular Standard execution matches your activity; paid accounts should be evaluated as complete packages.
