Function build_unwrap_bundle 

pub fn build_unwrap_bundle(
    _signer: Pubkey,
    _mint_stable: Pubkey,
    _amount: u64,
    _protocols: &[ProtocolAllocation],
) -> Vec<Instruction>

Builds a bundle of unwrap instructions for withdrawing across multiple protocols.

For large withdrawals that span multiple protocols, this function calculates the optimal split and returns multiple instructions that should be submitted as a Jito bundle for atomic execution.

Arguments

• signer - The user’s wallet address
• mint_stable - The stablecoin mint address
• amount - Total amount of stablecoins to unwrap
• protocols - List of protocols with their available USDC balances

Returns

A vector of instructions, one per protocol that needs to be withdrawn from. Submit these as a Jito bundle for atomic execution.

Example

let protocols = vec![
    ProtocolAllocation { protocol_id: PROTOCOL_KAMINO, usdc_available: 1000_000000 },
    ProtocolAllocation { protocol_id: PROTOCOL_PERENA, usdc_available: 500_000000 },
];
let bundle = build_unwrap_bundle(signer, mint, 1200_000000, &protocols);
// bundle[0] = unwrap 1000 USDC from Kamino
// bundle[1] = unwrap 200 USDC from Perena
