Anchor IDL

https://github.com/raydium-io/raydium-idl

anchor idl fetch <PROGRAM_ID> --provider.cluster mainnet

# 使用 anchor CLI
anchor build
anchor idl parse \
  --file target/idl/cpmm.json \
  --out target/types/cpmm.ts

# 或使用 `@anchor-lang/core` TS 幫助程式在執行時：

import { Program, AnchorProvider } from "@anchor-lang/core";
// 直接從 raydium-idl 儲存庫拉取 IDL（或將其供應到你的專案中）。
import cpmmIdl from "./idls/raydium_cp_swap.json";

const provider = new AnchorProvider(connection, wallet, {});
// Anchor >= 0.30 從 `idl.address` 讀取程式 id——這些 IDL 是規格 0.1.0
// 並攜帶它。三參數形式 `new Program(idl, programId, provider)` 是
// pre-0.30 並拋出。
const program  = new Program(cpmmIdl as any, provider);

// 自動產生的類型化方法建構器：
await program.methods
  .swapBaseInput(new BN(amountIn), new BN(minAmountOut))
  .accounts({ ... })
  .rpc();
