# 合约 ABI

## 直接从 forge build 拿

```bash
cd contracts && forge build
ls out/PoBRegistry.sol/PoBRegistry.json # 含 abi 字段
```

## TypeScript import

```typescript
import PoBRegistryAbi from 'contracts/out/PoBRegistry.sol/PoBRegistry.json';
const abi = PoBRegistryAbi.abi;
```

或用 wagmi cli 自动生成 typed ABI。

## Cast interface 导出

```bash
cast interface 0xdD7870A759Cbe9B755e33ce10Fbc16962c6b44B7 \
    --rpc-url https://rpc-testnet.axblade.io \
    > IPoBRegistry.sol
```

## SDK 内置

`@babydriver/sdk` 已 bundle 9 个核心合约 ABI + Typed client。详见 [TypeScript SDK](/integration-jie-ru-fang-shi/sdk-typescript.md)。
