通俗易懂
加密术语
订单类型, fee tiers, custody terms — the jargon you'll run into, defined without the buzzwords.
A
API key
A pair of strings (key + secret) that lets a bot or third-party tool act on your account. Every key is scoped (read-only / trade / withdraw) and can be locked to specific IP addresses. Generate from Account → 安全 → API keys.
C
冷存储
Keys held offline, typically in geographically distributed multi-sig hardware wallets. 提取als from cold storage to hot wallets require manual approval and rate-limit signing.
F
资金费率
A periodic payment between long and short holders of a perpetual contract, sized to keep the perp's price tethered to spot. Positive funding means longs pay shorts; negative means the reverse. We update funding every 8 hours.
L
限价单
按指定价格或更优价格買賣的订单。停留在订单簿中,直至撮合或取消。本身不会推动市場; be partially filled.
清算
Forced closing of a margin position when its collateral falls below maintenance margin. The exchange's liquidation engine takes over the position and unwinds it; any deficit is covered by the insurance fund.
M
Maker / Taker
A maker order adds liquidity to the order book (it sits there waiting). A taker order removes liquidity (it crosses the spread and fills immediately). Maker fees are usually lower because makers improve the book.
杠杆(全仓 / 逐仓)
全仓:杠杆钱包中的所有抵押品共同支持每个头寸;一笔亏损交易可能侵蚀另一笔的保证金。 Isolated:每个头寸有獨立隔离的抵押品;最坏情况是仅損失该头寸的保证金。
O
订单簿
The list of all unfilled buy orders (bids) and sell orders (asks) on a market, sorted by price. The top of the book is the best bid and best ask; their difference is the spread.
S
Slashing
A penalty applied to a staking validator that misbehaves (downtime, double-signing). A portion of the validator's stake — and your delegated stake — is destroyed by the protocol.
滑点
The difference between the expected price of a market order 与 price at which it actually fills, caused by the order eating through multiple book levels. Bigger orders → more slippage.
現貨交易
Buying or selling a crypto asset for immediate settlement at the current market price. No leverage, no liquidations, no funding — just the asset for cash (or another asset).
U
利用率
For lending markets: the fraction of supplied funds that's currently borrowed. Higher utilization → higher borrow APY → higher supply APY → equilibrium. Stablecoins typically run at 75–85% utilization.
W
WebSocket
A bidirectional connection that pushes order book updates and trade events to a client in real time. Faster than polling REST, 与 canonical way to consume live market data on bitexasia.
