QUESTIONS AND ANSWERS

What's the difference between taker and maker?
Taker is someone who "takes" liquidity from the order book, executing a market order at current price. Maker is someone who "creates" liquidity by placing a limit order and waiting for execution. Takers usually pay higher fees but get instant execution. Makers pay less but risk waiting and not getting filled.
Why account for price slippage?
When you make a trade (especially large), execution price is usually worse than quoted — this is called slippage. It's more noticeable on market orders, less on limit orders, but there's non-execution risk. We show this component separately so you see the real operation cost.
Why is 5 USDT withdrawal important?
Fixed USDT withdrawal fee in ERC-20 network on exchanges is 5 USDT (~392₽). This is a significant amount, especially for smaller transactions. Via tetris.money there's no such fee — you receive USDT (ERC-20) directly, no need to withdraw from exchange wallet.
Why isn't P2P 0%?
On P2P platforms, platform commission may be 0% for buyer, but real cost is "embedded" in the listing rate. Sellers factor in their margin (usually 1–3%) into the price. So when calculating total cost, we account for this "rate markup" as a separate component.
What's included in 0.10% tetris.money?
0.10% is the sum of two fixed fees: 0.05% for RUB deposit/withdrawal to OIS Platform + 0.05% for RUBT/USDT conversion in Uniswap pool (pool fee tier). This is the base, to which market factors are added: pool slippage (~0.05% typical) and gas (~80₽).
What about gas, liquidity and risks?
Gas (Ethereum network fee) depends on network congestion, usually ≤1 USD. Liquidity in RUBT/USDT pool determines price loss: more liquidity = less slippage. Market risk — RUBT/USDT rate may change between decision and execution.
