SSO - Auth provider powered by Ethereum & Next.js .

Sign-In with Ethereum.

使用以太坊对加签后在服务端验证签名并存储在 Session & Cookies 中，进而实现同级域名下的 SSO 认证。

use ethereum to sign your signature, verify by your backend app, then store it to session & cookies, then you can auth with SSO.

• SSO Authentication with iron-session .
• Mapping Roles by SPSR NFT (BSC Test Network) .

Authentication

share session fields.

export interface Credential {
  siwe?: any;
  roles?: string[];
}

after login with https://next.implements.io . we can get roles and wallet address by cookie-session under .implements.io with the fields.

// app/middleware/iron.ts
import { EggAppConfig, Context } from 'egg';
import { getIronSession } from 'iron-session';

export default (iron: EggAppConfig['iron']) => {
  return async (ctx: Context, next: () => Promise<any>) => {
    const options = iron.options;

    // @ts-ignore
    const ironSession = await getIronSession(ctx.req, ctx.res, options);

    // @ts-ignore
    const { credential } = ironSession;

    if (credential) {
      ctx.session.siwe = credential.siwe;
      ctx.session.roles = credential.roles;
    }

    await next();
  };
};
