Tender

Layer 2 for IPFS / API Renderer for Web3 / Serverless for Ethereum

Tender is dynamic content serving P2P Protocol for Ethereum.

V1 Design

• A Code is hosted on IPFS
• The code runs on Deno
  • The runtime is sandboxed and stateless: Any side effects or state mutations are prohibited
• You can only query Ethereum, using as a state repository
• You can render responses as any format

import { render, web3 } from 'https://tender.dev/lib/mod.ts';

const uniToken = web3.eth.Contract(
  ethereum.abis.ERC20,
  'uni.uniswap.eth',
);

render({
  block: await web3.eth.getBlockNumber(),
  balance: await uniToken.balanceOf('hyojun.eth'),
});

After deploying the code on IPFS, you can render it with servin:

curl -XGET https://servin.io/ipfs/QmbWqxBEKC3P8tqsKc98xmWNzrzDtRLMiMPL8wBuTGsMnR
