Avantis - Place Order (Client-Side Execution)

Avantis trades are executed client-side via on-chain transactions on the Base network. Unlike other exchanges, orders are not routed through the Tide backend — the frontend signs and submits transactions directly to Avantis smart contracts.

Avantis execution uses client-side wallet signing via the useAvantisTrade React hook. The Tide backend provides data only (positions, orders, history, balances). Trade execution happens on-chain.

Open Position

useAvantisTrade().openPosition({
  symbol: "ETH",                    // Pair from PAIR_INDEX_MAP
  direction: "LONG",                // "LONG" or "SHORT"
  positionSizeUsd: "100.00",        // Collateral in USDC
  leverage: 10,                     // See leverage rules below
  openPrice: "3420.50",             // Required for all order types
  orderType: "MARKET",              // MARKET, LIMIT, STOP_LIMIT, or MARKET_ZERO_FEE
  slippagePercent: 0.3,             // Default: 0.3
  tp: "4000",                       // Take-profit price (optional)
  sl: "3000"                        // Stop-loss price (optional)
})
// Returns: { txHash, symbol, direction, size, leverage }
