Solana HTTP Server

A Rust-based HTTP server providing Solana blockchain functionality through RESTful endpoints

Features

• Generate Solana keypairs
• Create SPL token mint instructions
• Create token minting instructions
• Sign and verify messages using Ed25519
• Create SOL transfer instructions
• Create SPL token transfer instructions

Setup

1. Install Rust and Cargo

2. Clone this repository

3. Install dependencies:

   cargo build

4. Run the server:

   cargo run

The server will start on http://localhost:3000

API Endpoints

Health Check

curl http://localhost:3000/

Generate Keypair

curl -X POST http://localhost:3000/keypair

Create Token Mint

curl -X POST http://localhost:3000/token/create \
  -H "Content-Type: application/json" \
  -d '{
    "mintAuthority": "11111111111111111111111111111112",
    "mint": "11111111111111111111111111111113",
    "decimals": 6
  }'

Mint Tokens

curl -X POST http://localhost:3000/token/mint \
  -H "Content-Type: application/json" \
  -d '{
    "mint": "mint-address",
    "destination": "destination-address", 
    "authority": "authority-address",
    "amount": 1000000
  }'

Sign Message

curl -X POST http://localhost:3000/message/sign \
  -H "Content-Type: application/json" \
  -d '{
    "message": "Hello, Solana!",
    "secret": "base58-encoded-secret-key"
  }'

Verify Message

curl -X POST http://localhost:3000/message/verify \
  -H "Content-Type: application/json" \
  -d '{
    "message": "Hello, Solana!",
    "signature": "base64-encoded-signature",
    "pubkey": "base58-encoded-public-key"
  }'

Send SOL

curl -X POST http://localhost:3000/send/sol \
  -H "Content-Type: application/json" \
  -d '{
    "from": "sender-address",
    "to": "recipient-address",
    "lamports": 100000
  }'

Send Tokens

curl -X POST http://localhost:3000/send/token \
  -H "Content-Type: application/json" \
  -d '{
    "destination": "destination-address",
    "mint": "mint-address",
    "owner": "owner-address", 
    "amount": 100000
  }'

Response Format

All endpoints return JSON responses with this structure:

Success (200):

{
  "success": true,
  "data": { /* endpoint-specific data */ }
}

Error (400):

{
  "success": false,
  "error": "Error description"
}

Security Notes

• Private keys are never stored on the server
• All cryptographic operations use standard, audited libraries
• Input validation is performed on all endpoints
• Ed25519 signatures are used for message signing/verification
