Apply Solana development patterns used throughout the Pump SDK: Anchor IDL-based program interaction, SPL Token and Token-2022 account management, transaction construction with instruction composition, RPC batching, and cross-program account coordination.

Anchor Program Initialization

import { Program, AnchorProvider } from '@coral-xyz/anchor';

function getPumpProgram(connection: Connection): Program<Pump> {
    const provider = new AnchorProvider(
        connection,
        { publicKey: PublicKey.default, signTransaction: async (tx) => tx, signAllTransactions: async (txs) => txs },
        { commitment: 'confirmed' }
    );
    return new Program(pumpIdl as Pump, PUMP_PROGRAM_ID, provider);
}
