Function orca_whirlpools_docs::orca_whirlpools::create_splash_pool_instructions

pub async fn create_splash_pool_instructions(
    rpc: &RpcClient,
    token_a: Pubkey,
    token_b: Pubkey,
    initial_price: Option<f64>,
    funder: Option<Pubkey>,
) -> Result<CreatePoolInstructions, Box<dyn Error>>

Creates the necessary instructions to initialize a Splash Pool.

Arguments

• rpc - A reference to a Solana RPC client for communicating with the blockchain.
• token_a - The public key of the first token mint address to include in the pool.
• token_b - The public key of the second token mint address to include in the pool.
• initial_price - An optional initial price of token A in terms of token B. Defaults to 1.0 if not provided.
• funder - An optional public key of the account funding the initialization process. Defaults to the global funder if not provided.

Returns

A Result containing CreatePoolInstructions on success:

• instructions - A vector of Solana instructions needed to initialize the pool.
• initialization_cost - The estimated rent exemption cost for initializing the pool, in lamports.
• pool_address - The public key of the newly created pool.
• additional_signers - A vector of Keypair objects representing additional signers required for the instructions.

Errors

This function will return an error if:

• The funder account is invalid.
• Token mints are not found or have invalid data.
• The token mint order does not match the canonical byte order.
• Any RPC request to the blockchain fails.

let token_b = Pubkey::from_str("TOKEN_MINT_ADDRESS_B").unwrap();
let initial_price = Some(0.01);

let wallet = Keypair::new();
let funder = Some(wallet.pubkey());

let create_pool_instructions = create_splash_pool_instructions(

    funder,
).unwrap();
