Understanding Ethereum Addresses & EIP-55 Checksums
An Ethereum address is a 160-bit hash represented as a 42-character hexadecimal string beginning with 0x. It is derived by calculating the Keccak-256 cryptographic hash of an ECDSA public key on the secp256k1 elliptic curve and taking the last 20 bytes.
Because hex strings are case-insensitive, simple typos can lead to irreversible loss of funds. In 2016, Vitalik Buterin introduced EIP-55, which encodes a checksum into the capitalization of alphabetical letters (A-F). The i-th character is capitalized if the i-th nibble of the address's Keccak hash is greater than or equal to 8. This ensures that any single-character typo has a 99.986% chance of failing checksum validation.
Ethereum Gas Mechanics & EIP-1559
Every computation executed on the Ethereum Virtual Machine (EVM)—from sending native ETH to interacting with complex DeFi liquidity pools—requires computational resources measured in units of Gas:
- Base Fee: Automatically determined by block congestion under EIP-1559 and burned completely from circulation.
- Priority Fee (Tip): Optional incentive paid directly to block validators to prioritize inclusion in the next block.
- Gas Limit: The maximum amount of gas units a user authorizes for a transaction (standard ETH transfers require exactly 21,000 gas units; ERC-20 token transfers typically require 45,000 to 65,000 gas units).
Frequently Asked Questions
- Can a lost Ethereum transaction be reversed?
- No. The Ethereum blockchain is an immutable distributed ledger. Once a transaction is confirmed and included in a finalized block, it cannot be canceled, refunded, or altered by any central authority.
- What is an ENS (.eth) domain?
- The Ethereum Name Service (ENS) is a decentralized domain naming protocol built on smart contracts. It maps human-readable names like
vitalik.ethto complex hexadecimal machine addresses, eliminating the need to copy 42-character hashes. - How does client-side Keccak-256 verification work?
- The browser executes a pure JavaScript implementation of the original Keccak-256 algorithm (NIST SHA-3 precursor used by Ethereum) across the lowercase address string, verifying each letter's case against the resulting hash bits entirely inside memory.

Why it matters
Public blockchain ledgers are completely transparent, but raw hexadecimal hashes and Wei values can be cumbersome to decipher. This client-side explorer translates raw Ethereum addresses and logs into clean, readable financial overviews with EIP-55 checksum validation, interactive Wei/Gwei converters, and wallet QR codes without tracking your IP or connecting your Web3 wallet.
When to use it
Use this tool to audit Ethereum wallet balances, verify mixed-case EIP-55 checksums before sending crypto transactions, convert Wei and Gwei gas units, or inspect smart contract deployment parameters safely and privately.
