Quick Start
This guide will help you get started with such essential Everscale tools as:
You will learn how to:
- Create and compile your first Solidity contract
- Run Local blockchain for testing
- Deploy your first contract
- Run it on-chain
- Run a getter-function
- Make a transfer
- Explore contract data in Explorer and GraphQL playground
- Switch to the developer network
- Configure Evercloud access
- Configure devnet giver
$ npm install -g everdev
$ everdev sol create helloWorld
Using Solidity compiler:
$ everdev sol compile helloWorld.sol
$ everdev sold install
$ export PATH="/home/<username>/.everdev/sold:$PATH"
$ sold helloWorld.sol
Attention: Docker should be running.
$ everdev se start
$ everdev network default se
Note: it may be already configured if you make a clean install of the latest Everdev. Then you can skip this step. If you are updating from some old version, it is necessary.
$ everdev signer add seGiver 172af540e43a524763dd53b26a066d472a97c4de37d5498170564510608250c3

Attention! This giver is available only in SE. If you work in mainnet or devnet, you need to deploy your own giver - more details below.

$ everdev signer default owner_keys

*Note that there are shortcuts for all the commands: s l = signer list :)
**Don't forget to make the owner key default otherwise giver keys will be used as default.
$ everdev c i helloWorld
Configuration
Network: se (http://localhost)
Signer: owner_keys (public 3826202b129ea8c041b8d49a655512648fc94377d1958a7a4fc9f4b3051ecf7b)
Address: 0:e74c4258496e79e62e014ca96911acbf5cb0e286fd55dd6f4e3da54e4197ddf5 (calculated from TVC and signer public)
Code Hash: c517820144a4daf5a3414c9233556b2b0ad34cdd228f200ea68a4c0327e0bd29 (from TVC file)
Account: Doesn't exist
You can see that the contract does not exist yet (is not deployed) but you can already see its future address.
Here we deploy the contract, sponsoring it with 10 Tokens (Everscale native currency has 9 decimals). The money for deploy are taken from the giver we configured in the previous steps.
$ everdev contract deploy -v 10000000000 helloWorld
Configuration
Network: se (http://localhost)
Signer: owner_keys (public 3826202b129ea8c041b8d49a655512648fc94377d1958a7a4fc9f4b3051ecf7b)

Deploying...
Contract has deployed at address: 0:e74c4258496e79e62e014ca96911acbf5cb0e286fd55dd6f4e3da54e4197ddf5
Go to localhost and search for your contract address in search bar. Open your account page. You will need it later to see its transactions and messages, that we will produce in the next steps.
Go to localhost/graphql. Enter in the left pane and click Run button (replace the contract's address with the one you got in the previous steps).
query {
accounts(
filter: {
id: {
eq: "0:e74c4258496e79e62e014ca96911acbf5cb0e286fd55dd6f4e3da54e4197ddf5"
}

You can specify any other fields in the result section that are available in GraphQL Schema. (Click
Docs on the right side of your screen to explore it).What is GraphQL? This is the API of blockchain, to retrieve data from it and to send data into it. You can use this playground later, if you will need need to test some queries.
Let's move on and run an on-chain method.
$ everdev c run helloWorld
Configuration
Network: se (http://localhost)
Signer: owner_keys (public 83cb989d99bce34dd7c04dd05a8a155f2a268d241ef8ec41c4c431cce0827f2d)

Available functions:
1) renderHelloWorld
2) touch
3) sendValue
4) timestamp
Select function (number):
Let's enter 3. You will see the transaction ID of the operation.
"transaction": {
"json_version": 5,
"id": "8087f774d4b8b4d4716cb31a74deea32550a04b40e853f55c64579fa3897108f",
"boc": "te6ccgECBw......
........................
You can also execute it inline like this:
$ everdev c run helloWorld touchIn the result you can see the transaction_id. Search for it on your Contract's page in Explorer and in GraphQL playground (use
transactions collection instead of accounts).$ everdev c run-local helloWorld timestamp

Running...
Execution has finished with result: {
"transaction": {

Attention!
- Contracts take value in nanotokens, so in this step we transferred 1 token.
- Bounce = true means that if the recipient does not exist, money will be returned back. If you plan to transfer money for deploy, specify Bounce = false!
Again, now you can find this transaction in Explorer or GraphQL API.
The Development Network, aka devnet is the Everscale test network with free test tokens that has an identical configuration to mainnet. You can test your contracts in a live environment on it.
To access devnet, you need to create an account and a project on https://dashboard.evercloud.dev/. Follow this guide to do it.
You will get your personal project ID, optional secret key and an endpoint of the following format:
https://devnet.evercloud.dev/<projectID>/graphql
To set devnet up as the default network in everdev, do the following:
everdev network default dev
Go to your Evercloud dashboard, find your "Project Id" and "Secret" (optional) on the "Security" tab, and pass them as parameters:
everdev network credentials network_name --project <Project Id> --access-key <Secret>
Example:
everdev network credentials dev --project 01234567890123456789012345678901 --access-key 98765432109876543210987654321098
While working with SE network, you already have a preset giver. In Devnet you need to configure your own.
This contract can be some multisig wallet, for example your Surf account (don't forget to switch it to devnet too!).
To get test tokens to your future giver, go to your Evercloud dashboard, open the Endpoints tab of your project, and click the faucet button next to Development Network. Specify the address and you will get some free test tokens.
Save the keys of your giver account into a signer that will be used to sign giver transactions:
everdev signer add giver_sign signer_secret_key_or_seed_phrase_in_quotes
Then add the giver address specifying the signer to be used with it.
everdev network giver dev giver_address --signer giver_sign --type giver_type
Where
giver_type is the type of the giver contract you selected (GiverV1 | GiverV2 | GiverV3 | SafeMultisigWallet | SetcodeMultisigWallet) - for Surf use SetcodeMultisigWallet.
Now you can do all the steps of this guide on devnet and see your transactions on your GraphQL playground at https://devnet.evercloud.dev/<projectID>/graphql and ever.live!
