drift

Use driftClient.placePerpOrder with OrderType, marketIndex, PositionDirection, and baseAssetAmount converted via convertToPerpPrecision. Limit orders also require a price converted with convertToPricePrecision, and trigger orders need triggerPrice and triggerCondition.

Install @drift-labs/sdk, @solana/web3.js, and @coral-xyz/anchor, then create a DriftClient with a Connection, Wallet, and env set to mainnet-beta or devnet. Call subscribe() before querying accounts, and initialize a user account if one does not exist.

Yes, the driftpy package provides a Python DriftClient with async methods for subscribing, initializing user accounts, and trading. Install it with pip install driftpy and use it with solders and anchorpy for wallet handling.

This error occurs when a post-only limit order would execute as a taker by crossing the spread. Adjust the price away from the current ask, use PostOnlyParams.TRY_POST_ONLY to skip silently, or PostOnlyParams.SLIDE to auto-adjust the price.

Use driftClient.convertToPerpPrecision for perp sizes, convertToSpotPrecision with the market index for spot tokens, and convertToPricePrecision for prices. For reading values, use convertToNumber with constants like QUOTE_PRECISION (10^6) and BASE_PRECISION (10^9).

Depositors call requestWithdraw with a share amount, wait for the vault's redeem period, then call withdraw to complete the process. Managers cannot bypass the redeem period or directly withdraw user funds.
