Market Parameters

Each market has precision parameters that control valid order sizes and prices, returned from GET /api/v1/markets. For conversion formulas, see Formatting Prices and Sizes.

These values reflect mainnet at the time of writing. Always fetch live values from GET /api/v1/markets — parameters can change via governance.

Order Size

human = chain_value / 10^sz_decimals — sizes must be a multiple of Lot Size and at least Min Size.

Market	sz_decimals	Min Size	Lot Size
APT/USD	5	1 APT `(100,000)`	0.1 APT `(10,000)`
BNB/USD	7	0.002 BNB `(20,000)`	0.001 BNB `(10,000)`
BTC/USD	8	0.00002 BTC `(2,000)`	0.00001 BTC `(1,000)`
DOGE/USD	4	20 DOGE `(200,000)`	1 DOGE `(10,000)`
ETH/USD	8	0.0005 ETH `(50,000)`	0.0001 ETH `(10,000)`
HYPE/USD	6	0.05 HYPE `(50,000)`	0.01 HYPE `(10,000)`
SOL/USD	7	0.02 SOL `(200,000)`	0.001 SOL `(10,000)`
SUI/USD	5	1 SUI `(100,000)`	0.1 SUI `(10,000)`
XRP/USD	5	1 XRP `(100,000)`	0.1 XRP `(10,000)`
ZEC/USD	7	0.005 ZEC `(50,000)`	0.001 ZEC `(10,000)`

Price

human = chain_value / 10^6 (prices are in USDC, px_decimals = 6) — prices must be a multiple of Tick Size.

Market	Tick Size
APT/USD	$0.0001 `(100)`
BNB/USD	$0.01 `(10,000)`
BTC/USD	$0.10 `(100,000)`
DOGE/USD	$0.00001 `(10)`
ETH/USD	$0.10 `(100,000)`
HYPE/USD	$0.001 `(1,000)`
SOL/USD	$0.01 `(10,000)`
SUI/USD	$0.0001 `(100)`
XRP/USD	$0.0001 `(100)`
ZEC/USD	$0.01 `(10,000)`

Fetching Live Values

import { DecibelReadDex, MAINNET_CONFIG } from "@decibeltrade/sdk";

const sdk = new DecibelReadDex({ config: MAINNET_CONFIG });
const markets = await sdk.getMarkets();

for (const market of markets) {
  const minSize = market.min_size / 10 ** market.sz_decimals;
  const lotSize = market.lot_size / 10 ** market.sz_decimals;
  const tickSize = market.tick_size / 10 ** market.px_decimals;

  console.log(`${market.market_name}: min=${minSize}, lot=${lotSize}, tick=$${tickSize}`);
}
