Free Solana developer tools — token lookup, wallet checker, rug scanner (all browser-based)

#solana #blockchain #webdev #crypto

I've been building free developer tools at DevTools.run and just shipped three Solana-specific tools that I think the crypto dev community will find useful.

Solana Token Lookup

devtools-site-delta.vercel.app/sol-token

Paste any SPL token mint address and instantly see:

Token name, symbol, and logo (from Jupiter API)
Current price in USD
Total supply and decimals
Direct link to Solscan

Includes quick-fill buttons for SOL, USDC, and BONK.

Solana Wallet Checker

devtools-site-delta.vercel.app/sol-wallet

Enter any Solana wallet address to see:

SOL balance with live USD value
All SPL token holdings
Last 10 transactions with status
Links to Solscan for everything

CLI Version: solcheck-cli

If you prefer the terminal:

npm install -g solcheck-cli

# Check a wallet
solcheck <wallet-address>

# Look up a token
solcheck token <mint-address>

Zero dependencies, pure Node.js. Shows balance, tokens, transactions with colored output.

npm: npmjs.com/package/solcheck-cli
GitHub: github.com/TateLyman/solcheck-cli

How it works

Everything runs client-side in your browser using:

Solana mainnet RPC (api.mainnet-beta.solana.com) for on-chain data
Jupiter API for token metadata and prices
CoinGecko for SOL/USD price

No data is sent to any server I control. Your wallet addresses and queries stay on your machine.

Tech stack

Next.js + TypeScript + Tailwind CSS
@solana/web3.js for RPC calls
All client-side, deployed on Vercel

The whole site (22 tools total) is open source: github.com/TateLyman/devtools-run

Building more Solana tools — what would be useful? Token safety scanner / rug checker is coming next.
