Swapping Through Hadron

Build a swap instruction.

use hadron_sdk_v2::types::SwapParams;

let ix = pool.swap(&user, &SwapParams {
    is_x: true,            // true = sell X for Y, false = sell Y for X
    amount_in: 1_000_000,  // in atoms
    min_out: 950_000,      // minimum acceptable output — set this to protect against slippage
    fee_recipient,
    expiration: None,
});

Param	Type	Description
`user`	`&Pubkey`	The user’s wallet
`params.is_x`	`bool`	Direction: `true` = X→Y, `false` = Y→X
`params.amount_in`	`u64`	Input amount in token atoms
`params.min_out`	`u64`	Minimum output amount. The transaction fails with `SlippageExceeded` (error 8) if the pool cannot fill at this level or better. Set to `0` only in tests.
`params.fee_recipient`	`Pubkey`	Address that receives the operator’s fee portion of the spread
`params.expiration`	`Option<i64>`	Optional slot deadline — transaction fails with `Expired` (error 38) after this slot

Multi-pool routing Hadron does not currently support native matching across multiple propAMMs for the same asset. For multi-pool routing, use one of the supported aggregators or contact the Hadron team.
