​

Request with Filters

curl https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getProgramAccounts",

            "offset": 0,
            "bytes": "BASE58_ENCODED_BYTES"

Using web3.js

import { Connection, PublicKey } from '@solana/web3.js';

const connection = new Connection('https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY');

// Get all program accounts
const accounts = await connection.getProgramAccounts(
  new PublicKey('PROGRAM_ID')
);
console.log('Accounts:', accounts);

// Get filtered program accounts
async function getFilteredProgramAccounts(
  programId: PublicKey,
  filters: any[]
) {
  const accounts = await connection.getProgramAccounts(programId, {
    filters
  });
  
  return accounts.map(({ pubkey, account }) => ({
    pubkey: pubkey.toBase58(),
    data: account.data,
    lamports: account.lamports,
    owner: account.owner.toBase58(),
    executable: account.executable
  }));
}

​

Notes

1. Returns all accounts owned by a specific program
2. Filters can be applied to narrow down results
3. Account data can be sliced to reduce response size
4. The response is immediate as it reads from the current state
5. Different encodings can be specified for account data

​

Best Practices

1. Use filters to efficiently query specific accounts
2. Consider using dataSlice to reduce response size
3. Cache results when appropriate to reduce RPC load
4. Handle large result sets with pagination
5. Use appropriate encoding based on your needs

Use Cases

1. Program Account Analysis
   interface ProgramAccountAnalysis {
     pubkey: string;
     dataSize: number;
     dataHash: string;
     lamports: number;
     metadata: {
       timestamp: number;
     };
   }
   
   async function analyzeProgramAccounts(
     programId: PublicKey,
     filters?: any[]
   ): Promise<ProgramAccountAnalysis[]> {
     const accounts = await connection.getProgramAccounts(programId, {
       filters,
       encoding: 'base64'
     });
     
     return accounts.map(({ pubkey, account }) => {
       const data = account.data[0];
       const dataSize = Buffer.from(data, 'base64').length;
       
       return {
         pubkey: pubkey.toBase58(),
         dataSize,
         dataHash: require('crypto')
           .createHash('sha256')
           .update(data)
           .digest('hex'),
         lamports: account.lamports,
         metadata: {
           timestamp: Date.now()
         }
       };
     });
   }
   
2. Program Account Monitoring
   interface ProgramAccountChange {
     pubkey: string;
     type: 'created' | 'deleted' | 'modified';
     previous: any;
     current: any;
     difference: number;
   }
   
   class ProgramAccountMonitor {
     private previousAccounts: Map<string, any> = new Map();
     
     async monitorProgramAccounts(
       programId: PublicKey,
       filters?: any[],
       interval: number = 5000
     ): Promise<ProgramAccountChange[]> {
       const accounts = await connection.getProgramAccounts(programId, {
         filters
       });
       const changes: ProgramAccountChange[] = [];
       
       accounts.forEach(({ pubkey, account }) => {
         const address = pubkey.toBase58();
         const current = account;
         const previous = this.previousAccounts.get(address);
         
         if (!previous && current) {
           changes.push({
             pubkey: address,
             type: 'created',
             previous: null,
             current,
             difference: current.lamports
           });
         } else if (previous && !current) {
           changes.push({
             pubkey: address,
             type: 'deleted',
             previous,
             current: null,
             difference: -previous.lamports
           });
         } else if (previous && current) {
           const difference = current.lamports - previous.lamports;
           if (difference !== 0 || current.data[0] !== previous.data[0]) {
             changes.push({
               pubkey: address,
               type: 'modified',
               previous,
               current,
               difference
             });
           }
         }
         
         this.previousAccounts.set(address, current);
       });
       
       return changes;
     }
   }
   
3. Program Account Pagination
   interface ProgramAccountPage {
     accounts: Array<{
       pubkey: string;
       data: any;
       lamports: number;
     }>;
     total: number;
     page: number;
     pageSize: number;
     metadata: {
       timestamp: number;
     };
   }
   
   async function getProgramAccountPage(
     programId: PublicKey,
     page: number = 1,
     pageSize: number = 100,
     filters?: any[]
   ): Promise<ProgramAccountPage> {
     const accounts = await connection.getProgramAccounts(programId, {
       filters,
       encoding: 'base64'
     });
     
     const start = (page - 1) * pageSize;
     const end = start + pageSize;
     const pageAccounts = accounts.slice(start, end);
     
     return {
       accounts: pageAccounts.map(({ pubkey, account }) => ({
         pubkey: pubkey.toBase58(),
         data: account.data[0],
         lamports: account.lamports
       })),
       total: accounts.length,
       page,
       pageSize,
       metadata: {
         timestamp: Date.now()
       }
     };
   }
