getTokenLargestAccounts
retrieves the top 20 largest SPL token accounts in one request.getTokenLargestAccounts
method emerges as a pivotal tool for gleaning insights into the distribution of SPL (Solana Program Library) Tokens.
The getTokenLargestAccounts
RPC method offers a window into the Solana blockchain, allowing users to retrieve information about the 20 largest accounts for a specific SPL Token in one go, making it one of the most efficient methods for token distribution analysis.
This guide is designed to walk you through the essentials of the getTokenLargestAccounts
method, from understanding its parameters and responses to implementing basic examples in JavaScript. Python, and exploring real-life use cases. Let’s start with the basics first.
getTokenLargestAccounts
method, you must ensure access to a Solana node. Chainstack provides a seamless and effective platform to deploy and manage Solana nodes. Here’s how you get started:
getTokenLargestAccounts
RPC methodgetTokenLargestAccounts
method stands as an integral part of the Solana blockchain’s suite of RPC calls, designed specifically for identifying the major token holders of any given SPL Token. This method is instrumental for those seeking to analyze token distribution, providing a clear view of top token accounts at a glance.
Method structure:
getTokenLargestAccounts
endpoint within the Solana JSON RPC API, facilitating an efficient query process for retrieving SPL Token holder information.
finalized
: Targets the latest block recognized as finalized by a supermajority, offering the highest level of data reliability.confirmed
: Queries the most recent block voted on by a supermajority, balancing speed with a reasonable level of certainty.processed
: Provides data from the most recent block in the node’s ledger, prioritizing real-time information over completeness.getTokenLargestAccounts
is by using cURL
. Run the following command to retrieve the top 20 holders of the Ray token at the finalized
commitment:
jsonrpc
: Indicates the JSON RPC version used for the query.
result
: The core component of the response, which includes:
value
: An array of objects, each representing one of the top 20 largest token accounts, with fields such as:
address
: The base58 encoded string of the token account’s address.amount
: The token balance of the account, represented as a string of u64, not adjusted for decimals.decimals
: The number of decimal places for the token, aiding in accurately representing the amount.uiAmountString
: The token balance adjusted for decimals, providing a more user-friendly representation of the amount.getTokenLargestAccounts
into JavaScript and Python projectscURL
is an excellent tool for initial tests, but DApps demand more sophisticated frameworks. JavaScript and Python, two of the most widely used languages in blockchain development, offer the robustness and flexibility required for such tasks. This section showcases the development workflow by guiding you through the setup process and providing practical examples in both languages.
npm
:
'YOUR_CHAINSTACK_ENDPOINT'
with your specific Solana endpoint. Executing this script will yield results similar to those obtained through cURL
but in a format that’s easier to process and analyze.
pip
:
python3 -m venv solana-project
, then activate it with source/solana-project/bin/activate
.'YOUR_CHAINSTACK_ENDPOINT'
, this script includes some processing to display the result in a more friendly way.
By following these examples, you can effectively employ the getTokenLargestAccounts
method in both JavaScript and Python to simplify the integration of this functionality into blockchain applications or data analyses significantly.
getTokenLargestAccounts
use casesgetTokenLargestAccounts
method within the Solana ecosystem, we now pivot to a practical, real-life use case that demonstrates the method’s utility in action.
This section will guide you through a Python project designed to fetch and visualize the distribution of SPL Token holdings among the largest accounts. This real-world application bridges the gap between theoretical knowledge and practical implementation, showcasing how developers can utilize Solana’s blockchain data to generate insightful visualizations.
fetch_largest_accounts
function:
get_token_largest_accounts
method of the Solana Python client. It retrieves data on the 20 largest accounts holding the specified SPL Token, focusing on the finalized state for reliability.plot_token_balances
function:
matplotlib
library to plot the token balances of the largest accounts. It creates a bar chart where each bar represents the token balance of an account, providing a visual comparison across the top holders. Account addresses are used as labels on the x-axis, with their corresponding token balances displayed on the y-axis. The y-axis labels are formatted for readability, showing large numbers in a concise format.main
function:
fetch_largest_accounts
function. It extracts the necessary information from the response (addresses and UI amounts) and passes it to the plot_token_balances
function for visualization.matplotlib

getTokenLargestAccounts
method within the Solana ecosystem, a tool of paramount importance for developers, investors, and analysts alike. From setting up a Solana RPC endpoint with Chainstack to diving deep into the method’s structure and integrating it into development projects to a hands-on, real-life application, we’ve explored the multifaceted utility of this method in unlocking insights into SPL Token distribution.
