DevSOL

Solana devnet SOL marketplace. Buy and sell devnet SOL instantly via x402 payments.

Problem

Solana devnet faucets are unreliable and heavily rate-limited. Developers waste valuable time waiting for devnet SOL instead of building. DevSOL provides instant, reliable access to devnet SOL for a small fee.

How It Works

  • Buy: Pay USDC (Solana mainnet) via x402 protocol → receive devnet SOL instantly
  • Sell: Send devnet SOL to treasury → receive USDC on Solana mainnet

Pricing

Action Rate
Buy 1 SOL devnet = 1.05 USDC
Sell 1 SOL devnet = 0.95 USDC

Stack

  • Runtime: Node.js + Hono
  • Payments: x402 protocol (@x402/svm, @x402/hono)
  • Blockchain: @solana/kit (mainnet + devnet)
  • Database: SQLite (transaction log)
  • Deployment: Docker on VPS, nginx reverse proxy
