To send an EIP-1559 transaction in Python, you build a Type 2 transaction with two fee fields — maxFeePerGas and maxPriorityFeePerGas — sign it with your private key, and broadcast it using web3.py’s send_raw_transaction. That’s the whole flow. What trips…
eth_getLogs is the Ethereum JSON-RPC method that returns every event log matching a filter you supply — a contract address, a block range, and a set of topics. It’s the standard way to pull historical crypto logs after the fact:…
A stuck Ethereum transaction is one that has been broadcast but sits unconfirmed in the mempool — the pool of pending transactions waiting to be included in a block — because its fee is too low for current demand. You…
Forking Ethereum mainnet means running a local copy of the live chain on your own machine, seeded with real mainnet data. You get the actual deployed contracts, token balances, and protocol state, but every transaction you send stays local and…
A batch request packs several blockchain queries into one HTTP call instead of sending them one at a time. On Ethereum that means fewer round trips, lower latency, and code that finishes a wall of reads in a single network…
A blockchain indexer reads data straight from a chain, decodes it into structured records, and stores those records in a database your application can query in milliseconds. Without one, answering a question as simple as “what tokens does this wallet…
The best Polkadot wallet for most people is Nova Wallet on mobile or Talisman on desktop, paired with a Ledger device if you hold a large amount of DOT. That short answer covers the majority of use cases. The longer…
To integrate Solana into a Web3 project, you point your application at a node connection and send it JSON-RPC calls. Reads like account balances, writes like signed transactions, block lookups — all of it travels over that one connection. You…
There is no single best Ethereum wallet. The right one depends on what you actually do with ETH: minting an NFT, farming yield in DeFi, holding for years, or sharing control of a team treasury all point to different tools.…
The two largest decentralized exchanges on TON are STON.fi and DeDust, and the main venue for leveraged trading is Storm Trade. But “best” is the wrong question until you know what you’re trying to do. Swapping one jetton for another,…
