NEAR CLI - Basics

After your contract is ready you can deploy it in the NEAR network for everyone to use it.

Let us guide you on how to use the NEAR CLI to deploy your contract and call its methods.


Deploying a Contract

Thanks to the NEAR CLI deploying a contract is as simple as:

  1. Compiling the contract to wasm (done automatically through yarn build in our templates).
  2. Deploy it into the desired account using the NEAR CLI:
# Login to NEAR
near login

# Deploy wasm to the <accountId> account
near deploy <accountId> <route_to_wasm>
By default the contract will be deployed to the testnet. To deploy into mainnet you can set the NEAR_ENV variable to mainnet (export NEAR_ENV=mainnet). :::

Calling the Contract

Once your contract is deployed you can interact with it using your favorite shell. For this, you can use the NEAR CLI. Please notice that in this page we will only touch on how to use NEAR CLI to call methods in a contract. For the full documentation please visit the NEAR CLI documentation page.


View methods

View methods are those that perform read-only operations. Calling these methods is free, and do not require to specify which account is being used to make the call:

near view <accountId> <methodName>

Change methods

Change methods are those that perform both read and write operations. For these methods we do need to specify the account being used to make the call, since that account will expend GAS in the call.

near call <contractId> <methodName> <jsonArgs> --accountId <yourAccount> [--attachDeposit <amount>] [--gas <GAS>]
