2. fun.xyz SDK

3. Rollupid is defining our AA feature for developers.

How we think it should work:

• • Developers issue session keys and sponsor gas fees

• • Session keys are assigned the user role and have configurable limits

• • Bring your own AA provider for paymaster and bundlers

Rollupid 在平台里定义了AA的一些特性：

• • 开发者会话密钥和支付gas

• • 会话密码赋予用户角色和限制

• • 提供AA的paymaster和bundlers
