# ENS Workshop
O objetivo do workshop é que possamos deployar um contrato de Resolver da ENS com algumas informações pessoais, criar um domínio da ENS e depois usar esse proprio contrato que deployamos junto a interface frontend da ENS.
## Mint de eth na Sepholia
Para assinar a transação e criar um domínio de teste ENS, é necessário obter um pouco de ether na carteira. Para fazer isso, siga os próximos passos:
- Acesse um dos faucets da Sepolia, como https://sepolia-faucet.pk910.de/#/
Resolva o captcha e insira o endereço da sua carteira:
![]()
- Start mining to get founds:
![]()
- Depois de um minuto, clique em Parar de mineirar, e então os fundos vão ser transferidos para o seu endereço.
![]()
## Create ENS domain
Agora que já temos fundos na cadeia da Sepolia, é possível comprar nosso domínio de teste na ENS.
- Acesse o aplicativo da ENS (https://app.ens.domains/) e conecte sua carteira:
![]()
- Selecione sua conta com seploliaETH minerado.
![]()
- Escolha um nome para o seu domínio ENS.
![]()
- Selecione a duração do domínio.
![]()
- Inicie a transação.
![]()
- Aguarde a conclusão da transação.
![]()
- Confirmar transação.
![]()
- Profile criado!
## Deploy do Resolver
### Requirements
- [Metamask](https://metamask.io)
- [Foundry](https://book.getfoundry.sh/)
## Remix Deploy
[Remix Ethereum IDE](https://remix.ethereum.org)
```solidity
// SPDX-License-Identifier: GPL-3.0
pragma solidity >=0.8.2 <0.9.0;
import "https://github.com/ensdomains/ens-contracts/blob/staging/contracts/resolvers/PublicResolver.sol";
contract MyResolver is PublicResolver {
constructor(
ENS _ens,
INameWrapper wrapperAddress,
address _trustedETHController,
address _trustedReverseRegistrar
) PublicResolver(
_ens,
wrapperAddress,
_trustedETHController,
_trustedReverseRegistrar
) {
}
}
```
## Local deploy
### Installation
```shell
curl -L https://foundry.paradigm.xyz | bash
foundryup
```
### Start project
```shell
forge init eth-samba-ens
```
Remove `lib/forge-std` and add it as a submodule:
```shell
rm -rf lib/forge-std
forge install https://github.com/foundry-rs/forge-std --no-commit
```
Create `.gitignore`
```gitignore
.env
out/
cache/
```
### Deploy Public Resolver on localhost
```shell
forge create src/Counter.sol:Counter \
--rpc-url http://localhost:8545 \
--private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
```
#### Interact
```shell
# Set number
cast send 0x5fbdb2315678afecb367f032d93f642f64180aa3 "function setNumber(uint256 newNumber)" \
