Deploying the escrow contract

1.1 Set up project

Clone project:

$ git clone https://github.com/tashigg/tce-escrow-contract.git

Build:

$ npm i

$ forge build

Test:

$ forge test

Create file .env:

$ cd tce-escrow-contract

$ cp .env.example .env

1.2 Set up wallet

1.2.1 Create wallet

You must have an account in the EVM platform to deploy smart contracts. To have an account, you need to create a wallet. There are many E-Wallet Apps that allow you to create an account:

• Metamask

• Phantom

• AgentX

But the most popular is metamask. We will use metamask in this tutorial.

Steps:

1. Install: https://metamask.io/download/

   
2. Add extension to your browser

   
3. Create a new wallet. Accept agreements, follow prompts and create a password.

   

   

   
4. Secure wallet

   
5. Show Secret Recovery Phrase

   
6. Take a screenshot to save the secret recovery phrase. Any party who knows this recovery phrase can control the account, and can withdraw or transfer all tokens in the account, so keep the recovery phrase secret. Follow prompts to confirm that you have saved the secret recovery phrase.

   

   

   
7. You have successfully created a Metamask wallet with a new account. You should pin the Metamask wallet to your web browser.

   

1.2.2 Get Private Key

You will need the account's private key to deploy smart contracts. Like the secret recovery phrase, any party who knows this private key can control the account, so keep it secret.

Steps:

1. Open Metamask, select the desired account

   
2. Open account details

   
3. Show private key. Enter your wallet password and follow prompts to show the key.

   

   

   
4. Copy the private key

   

1.2.3 Get Public Key

Open Metamask and copy the public key:

1.2.4 Faucet

Your account balance must be sufficient to pay the smart contract deployment fee. If your balance account is sufficient, you can skip this section.

Network	Faucet Link
Polygon	https://faucet.polygon.technology
Bsc	https://www.bnbchain.org/en/testnet-faucet
Base	https://console.optimism.io/faucet
Blast	https://blastapi.io/faucets/blastl2-testnet
Avalanche	https://faucets.chain.link/fuji
Arbitrum	https://faucets.chain.link/arbitrum-sepolia
Optimism	https://console.optimism.io/faucet
ImmutableX	https://hub.immutable.com/faucet
Ronin	https://faucet.roninchain.com

We will use the Polygon network in this tutorial. The faucet for the polygon network can be found here: https://faucet.polygon.technology/

1.3 RPC Endpoints

Different networks have different RPC endpoints. We've listed them here, but you shouldn't need to manually input any of these because we've provided user-friendly aliases to these endpoints in the foundry.toml file. For more info, see section 1.6

Network	Mainnet	Testnet
Polygon	https://polygon-rpc.com	https://rpc-amoy.polygon.technology https://rpc-mumbai.polygon.technology
Bsc	https://bsc-dataseed-public.bnbchain.org	https://bsc-testnet-dataseed.bnbchain.org
Base	https://mainnet.base.org	https://sepolia.base.org
Blast	https://rpc.blast.io	https://sepolia.blast.io

Arbitrum	https://arb1.arbitrum.io/rpc https://nova.arbitrum.io/rpc	https://sepolia-rollup.arbitrum.io/rpc

ImmutableX	https://rpc.immutable.com	https://rpc.testnet.immutable.com

1.4 Set Up API Scan Key

You will need an API key to verify smart contracts.

Network	Scan
Polygon	https://polygonscan.com
Bsc	https://bscscan.com
Base	https://basescan.org
Blast	https://blastscan.io
Avalanche	https://snowtrace.io
Arbitrum	https://arbiscan.io
Optimism	https://optimistic.etherscan.io
ImmutableX	https://explorer.immutable.com
Ronin	https://app.roninchain.com

In this tutorial we will use the Polygon network. If you already have an API key or don’t need to verify your smart contract, you can skip this section.

Steps:

1. Login: https://polygonscan.com -> Sign In

   
2. Create API Key:

   
3. Generate API key. You need to enter your app name.

   
4. Get API Key

   

1.5 Config

Configure the .env file:

API_KEY_POLYGONSCAN = "Your_PolygonScan_API_Key" PRIVATE_KEY = "Your_Private_Key"

• API_KEY_POLYGONSCAN: Your Polygon scan API Key.

• PRIVATE_KEY: Your account private key. Copy and Paste private key. (Note: you may need to add "0x" to head of string)

1.6 Deploy & Verify Smart Contract

The foundry.toml file provides user-friendly aliases for the RPC endpoints of various networks. This means you won't need to manually type the endpoint URL in any commands.

Network	Mainnet Alias	Testnet Alias
Polygon	polygon	polygon_amoy
Bsc	bsc	bsc_testnet
Base	base	base_sepolia
Blast	blast	blase_sepolia
Avalanche	avalanche	avalanche_fuji
Arbitrum	arbitrum	arbitrum_sepolia
Optimism	optimism	optimism_sepolia
ImmutableX	immutableX	immutable_testnet
Ronin	ronin	ronin_saigon

Deploy:

$ forge script script/SessionManager.s.sol:SessionManagerScript --broadcast --rpc-url <network alias>

Deploy and Verify:

$ forge script script/SessionManager.s.sol:SessionManagerScript --broadcast --rpc-url <alias network> --verify

Example:

Deploy:

$ forge script script/SessionManager.s.sol:SessionManagerScript --broadcast --rpc-url polygon_amoy

Deploy & verify

$ forge script script/SessionManager.s.sol:SessionManagerScript --broadcast --rpc-url polygon_amoy --verify
