How to Validate a Crypto Address

01Choose networkSelect Auto-detect to let the tool infer the address format based on prefix patterns, or explicitly choose Bitcoin or EVM if you know the target chain. Auto-detection checks for the 0x prefix (EVM), bc1 prefix (Bech32 SegWit), or 1/3 prefix (Base58 legacy). Choosing the correct network prevents misvalidation — some formats look similar across chains but have different checksum algorithms.

02Paste addressPaste the full address into the input field. For EVM addresses, the tool verifies the 0x + 40 hex character format (EIP-55 defines a mixed-case checksum using keccak256 hashing, though this tool only checks format). For Bitcoin, it performs Base58Check validation by double-SHA256 hashing the payload and comparing the first 4 bytes against the embedded checksum. For Bech32 (SegWit bc1…), it runs a polymod checksum verification using the Bech32 specification with the human-readable part "bc".

03Open explorerAfter validation, a safe explorer link is provided so you can verify the address on-chain before sending funds. This is an essential security step — even if the checksum is valid, the address may belong to someone else or be a known scam address. Always cross-reference the address through a second trusted channel (phone call, in-person verification) for large transfers.

Privacy & Security

Runs locally in your browser. No API calls. No wallet connection. All validation is performed client-side using Web Crypto API for SHA-256 hashing.

About Address Validator

This tool validates formatting and checksums for Bitcoin (Base58Check and Bech32/SegWit) and EVM-style addresses (0x hex). Address validation is critical because crypto transactions are irreversible — sending to an invalid or mistyped address means permanent loss of funds. Each format uses a different checksum algorithm: Base58Check uses double-SHA256 (4-byte checksum appended to the payload), Bech32 uses a polymod checksum with generator polynomials for error detection, and EIP-55 encodes checksum information in the mixed-case of hex characters. All validation runs client-side using Web Crypto API — no data leaves your browser.

When to use it

Use this before sending funds to an address, when reviewing an address in a message or invoice, or when auditing addresses in a spreadsheet. Essential when copying addresses manually or verifying addresses received via untrusted channels. One wrong character in a crypto address means permanent loss.

Tips & Tricks

•Bech32 addresses (bc1…) are case-insensitive, but mixed-case is always invalid — the encoding is designed for lowercase-only display.
•EVM mixed-case checksum (EIP-55) is not verified here — lowercase addresses are always valid. Etherscan shows the checksummed version.
•If Auto-detect fails, try selecting the network manually — some formats are ambiguous (e.g., a short address starting with "1" could be BTC or another chain).
•Never trust an address from an unsolicited message — always verify it through a second channel. Scammers commonly replace addresses in copy-paste buffers.
