Solana: Retrieving Token Deployers and Previous Deployments with JavaScript and Python

Introduction

Solana is a decentralized, open-source blockchain platform that enables fast, secure, and scalable smart contract deployment. One of Solana’s key features is its ability to efficiently manage token deployments, including retrieving a token’s deployer and previously deployed tokens.

Retrieving Token Deployer with JavaScript

The Solana SDK provides a “deploy” function that can be used to retrieve the deployer of a token. However, this function only returns the current deployer, not the previous one.

import { deploy } from “@solana/web3.js”;
const deployer = await deploy('my-token', {
programId: “my-program-id”,
});
console.log(Deployer: ${deployer.deployer});

To retrieve previously deployed tokens, you need to use the get function provided by the Solana SDK. This function returns an array of all deployed programs, including the deployer.

import { get } from `@solana/web3.js';
const programId = 'my-program-id';
const deployer = await deploy(programId);
console.log(Deployer: ${deployer.deployer});
const deployedPrograms = await get(programId);
// Iterate through the programs array to find the previous one
for (const program of deployedPrograms) {
if (program.programId === programId && program Deployers.length > 0) {
const deployerProgram = program.Deployers[0];
console.log(Previous device: ${deployerProgram.deployer});
}
}

You can use the get_programsfunction provided by Solana to retrieve a list of programs, including their implementors and previous implementations.

import solana
def get_previous_deployments(program_id):
program = solana-program-client.client.get_program(program_id)
deployed_programs = solana-program-client.client.get_programs(program.id)









Find the previous deployment
for deployed in deployed_programs:
if deployed.program_id == program_id and deployed.Deployers[0].is_deployer:
return deployers [0]
return None

Replacemy-token'' with the program ID of your token
previous_deployer = get_previous_deployments('my-token')

Retrieving the deployer of a Solana token and previously deployed tokens can be done using the deployfunction, thegetfunction, or theget_programs` function provided by Solana SDK. By understanding these features, you can efficiently manage token deployments on your Solana-based smart contract.

Use Case Examples

• Retrieve implementors for multiple tokens in a single script

• Identify previously deployed programs to maintain historical data

• Optimize token deployment strategies based on implementor availability
