Blockchain Tools & Resources
Welcome to the Blockchain Tools & Resources Hub — your one-stop destination to explore essential tools, platforms, and references that every blockchain learner, enthusiast, or developer should know about.
This page is designed to equip you with the practical resources you need to learn faster, build confidently, and stay safe in the blockchain space.
A blockchain wallet is your digital key to interacting with blockchain networks. Whether you’re learning, investing, or developing, you’ll need a wallet to store cryptocurrencies and digital assets.
MetaMask (Ethereum & EVM-compatible)
Trust Wallet (Multi-chain mobile wallet)
Ledger Nano X (Hardware wallet for cold storage)
Phantom (Solana wallet)
Keplr (Cosmos ecosystem wallet)
Tip: Always back up your seed phrase safely and never share your private keys.
A blockchain explorer is like Google for blockchains — it lets you see transactions, wallet addresses, smart contracts, and network activity in real-time.
Etherscan — Ethereum explorer
https://etherscan.io
Blockchain.com Explorer — Bitcoin & Bitcoin Cash
https://www.blockchain.com/explorer
BscScan — Binance Smart Chain
https://bscscan.com
Solscan — Solana explorer
https://solscan.io
Polygonscan — Polygon network
https://polygonscan.com
Use Case:
Track transactions, check block confirmations, and verify smart contract activity.
When dealing with tokens, you'll often hear about different standards. Here are key references:
ERC-20 — Fungible tokens (Ethereum)
ERC-721 — Non-Fungible Tokens (NFTs)
ERC-1155 — Multi-token standard (fungible & non-fungible)
BEP-20 — Binance Smart Chain equivalent of ERC-20
SPL Token — Token standard on Solana
Official References:
Blockchain networks charge transaction fees, often referred to as gas fees. These fees can vary significantly based on network congestion.
Ethereum Gas Tracker — https://etherscan.io/gastracker
Polygon Gas Station — https://polygonscan.com/gastracker
Solana Fee Estimator — Available via Solana Explorer
Why it matters:
Understanding gas fees helps you avoid overpaying or being stuck with slow transactions.
Testnets are blockchain environments where you can practice, experiment, or develop without using real cryptocurrency.
Ethereum Goerli (soon deprecated) → Transitioning to Holesky
Polygon Mumbai
BNB Chain Testnet
Solana Devnet

Important:
Testnet tokens do not have real value and are used only for development & learning purposes.
