Short, practical guides to Ethereum, gas, block explorers and the tools around them — by ChainGate.
Binance closes its mining pool, Pool Savings, Cloud Mining and the BTC Transaction Accelerator at 07:00 UTC on November 10, 2026. What miners must do before the cutoff, how final payouts work, and how to speed up a stuck transaction without the accelerator, with live pool and fee data.
Sepolia forked on October 6, Hoodi forks on October 26 with a 200M gas limit, and mainnet has two candidate dates on the table, December 1 or December 8, with no decision yet. What the upgrade does to gas fees, contracts and validators, with today's live Ethereum numbers.
Send Bitcoin, Ethereum, Litecoin, Dogecoin and Bitcoin Cash from one SDK — five lines per chain, fee estimation and balance checks built in, Node.js and browser ready.
What a gas fee is, what gwei means, who gets the money, and how much an Ethereum transfer costs right now compared with Base, Arbitrum and Optimism.
The Ethereum block explorer, explained. What it does, how to look up transactions and addresses, how to read a verified smart contract, and which free tools complement it.
Bitcoin has no gas, it charges per virtual byte. Today's fee in sat/vB and dollars, how the number is built, why a small payment can cost more than a large one, and what Litecoin, Dogecoin and Bitcoin Cash charge.
The ID every wallet and exchange asks for: what it looks like on Bitcoin, Ethereum, Solana and XRP, where to copy yours, how to check it on a block explorer and why it sometimes stops working.
The chain IDs of Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Smart Chain, Avalanche and 30 more networks and testnets, in decimal and hex, with what the number does, how to look one up and why a wallet rejects the wrong one.
viem, ethers.js, wagmi, web3.js, bitcoinjs-lib, thirdweb, Tatum and ChainGate side by side: which chains each one covers, who brings the RPC, how they handle keys, and which to pick for an EVM dApp, a Bitcoin wallet or a multi-chain app.
When you are ready to put the ideas into code, ChainGate gives you wallets, transactions and managed RPC for Ethereum and 20+ other blockchains from a single TypeScript library.
