# Send Transactions in Near

Transactions are a formal action on a blockchain. They can be initiated in Sender with a call to NEAR's RPC node. They can be a simple sending of $NEAR, may result in sending fungible tokens, creating a new account, or changing state on the blockchain in any number of ways. They are always initiated by a signature from an NEAR account, usually with [a function call key or full access key](https://docs.near.org/docs/concepts/account#access-keys). 

### Sign and Send a Single Transaction

With Sender, you could sign and send a single transaction with one or multiple actions. 

```javascript
// Call wNEAR contract method 
// Register the 'xxx.testnet' account to wNEAR on testnet (wrap.testnet)
const tx = {
  receiverId: 'wrap.testnet',
  actions: [
    { 
      methodName: 'storage_deposit',
      args: {
        account_id: 'alice.testnet',
        registration_only: true,
      },
      gas: parseNearAmount('0.003'),
      deposit: parseNearAmount('0.00125'),
    },
  ],
}
const res = await window.near.signAndSendTransaction(tx);
```

```javascript
// Call multiple methods from wNEAR contract
// Swap NEAR to wNEAR, then transfer wNEAR to others
const tx = {
  receiverId: 'wrap.testnet',
  actions: [
    {
      methodName: 'near_deposit',
      args: {},
      deposit: parseNearAmount('1'),
    },
    { 
      methodName: 'storage_deposit',
      args: {
        account_id: 'bob.testnet',
        registration_only: true,
      },
      gas: parseNearAmount('0.003'),
      deposit: parseNearAmount('0.00125'),
    },
    {
      methodName: 'ft_transfer',
      args: {
        received_id: 'bob.testnet',
        amount: '1000000000000000000',
      },
      gas: parseNearAmount('0.003')
    }
  ]
}
const res = await window.near.signAndSendTransaction(tx);
```

### Sign and Send Multiple Transactions

Sender also supports sign and send multiple transactions when needed.

```javascript
const transactions = [
  {
    receiverId: wNearContractId,
    actions: [
      {
        methodName: 'near_deposit',
        args: {},
        amount: '100000000000000000000000',
      },
    ]
  },
  {
    receiverId: RefFinanceContractId,
    actions: [
      {
        methodName: 'add_liquidity',
        args: {
          tokens_ids: ['wrap.testnet', 'token.paras.testnet'],
          amounts: ['1000000000000000000', '1000000000000000000'],
        },
      }
    ]
  }
];

const res = await window.near.requestSignTransactions({ transactions });

console.log('Swap and Send wNEAR with requestSignTransactions response: ', res);
```
