Getting account information

Getting Account Balance

To retrieve the balance of an XRP Ledger account, you can use the following method:

const res = await provider.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:xrpl-snap',
    request: {
      method: 'xrpl_request',
      params: {
        command: 'account_info',
        account: 'rYourXRPAccountHere',
      },
    },
  },
})
console.log(res.account_data.Balance);
console.log(res.account_data.OwnerCount);

In the XRP Ledger you need 10 XRP to active your account.

The Balance will be returned in drops

Getting the available balance

The balance you get from the response is not the available balance that the account has to spend.

Each account has a reserve:

• Base reserve: 10 XRP

• Owner reserve: 2 XRP per item

So to get the available balance in drops:

$$available = Max(0, Balance - 10*10^6-2*10^6*OwnerCount)$$

Converting drops to XRP

A drop is the minimum amount valid in the XRP Ledger, each drop is equal to 0.000001 XRP.

You can easily convert drops to xrp with xrpl.js.

Submitting Transactions

Making a Payment

To send XRP from one account to another, you can submit a payment transaction:

provider.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:xrpl-snap',
    request: {
      method: 'xrpl_signAndSubmit',
      params: {
        TransactionType: 'Payment',
        Account: 'rYourXRPAccountHere', // The Snap's XRP account
        Destination: 'rRecipientXRPAccountHere',
        Amount: '1000000', // 1 XRP in drops
      },
    },
  },
})

This transaction sends 1 XRP from your account to the specified destination account.

Creating a Trustline

A trustline is required to hold tokens issued by other accounts on the XRP Ledger. Here’s how to create a trustline:

provider.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:xrpl-snap',
    request: {
      method: 'xrpl_signAndSubmit',
      params: {
        TransactionType: 'TrustSet',
        Account: 'rYourXRPAccountHere',
        LimitAmount: {
          currency: 'TOKEN', // Add the currency of the Token fe. USD
          issuer: 'rIssuerAccountHere',
          value: '1000', // Maximum amount of the token you can hold
        },
      },
    },
  },
})

This transaction establishes a trustline allowing your account to hold up to 1000 units of a specified token issued by another account.

Sending a Token

Once a trustline is established, you can send tokens to another account as follows:

provider.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:xrpl-snap',
    request: {
      method: 'xrpl_signAndSubmit',
      params: {
        TransactionType: 'Payment',
        Account: 'rYourXRPAccountHere',
        Destination: 'rRecipientXRPAccountHere',
        Amount: {
          currency: 'TOKEN',
          value: '10', // Number of tokens to send
          issuer: 'rIssuerAccountHere',
        },
      },
    },
  },
})

This transaction sends 10 units of the specified token from your account to the recipient's account.
