Pool Admin Control

​

setPoolState

use hadron_sdk_v2::types::{SetPoolStateParams, PoolState};

let ix = pool.set_pool_state(&authority, &SetPoolStateParams {
    new_state: PoolState::Initialized,
});

​

nominateAuthority / acceptAuthority

use hadron_sdk_v2::types::NominateAuthorityParams;

// Step 1: current authority nominates a new one
let ix1 = pool.nominate_authority(&authority, &NominateAuthorityParams {
    new_authority: new_pk,
    expiry_slot: current_slot + 50_000, // nomination expires after ~6 hours
});

// Step 2: new authority accepts
let ix2 = pool.accept_authority(&new_pk);

Authority types The pool has three distinct authority roles: Pool Authority (full admin — can do everything), Quoting Authority (can push oracle updates and switch pool to RejectSwaps), and Pauser Authority (can pause and unpause the pool). Each can be delegated to a different wallet using nominate_authority for the relevant role.

​

closePool

let ix = pool.close_pool(&authority);

Drain vaults first Call withdraw with the full vault balance for both token X and token Y before closing. The transaction will fail with error VaultsNotEmpty (code 52) if any balance remains.
