What blockchains does this tool support?

This tool supports Ethereum and all EVM-compatible chains (Polygon, BSC, Arbitrum, Base, Optimism), Bitcoin (P2PKH, SegWit Bech32, Taproot), Solana (Ed25519), and Tron (Base58Check). It also includes a built-in RPC client for querying Ethereum and Solana nodes directly. All operations run 100% in your browser.

What is the difference between P2PKH, SegWit, and Taproot Bitcoin addresses?

P2PKH (Pay-to-Public-Key-Hash) addresses start with 1 and are the original Bitcoin address format. SegWit (P2WPKH) addresses start with bc1q and offer lower transaction fees. Taproot (P2TR) addresses start with bc1p, support Schnorr signatures, and enable advanced smart contract capabilities.

How does the address validator auto-detect the blockchain?

The validator uses prefix and format heuristics: 0x-prefixed 42-char hex for EVM, Base58Check with version byte analysis for Bitcoin P2PKH/P2SH, bech32/bech32m for SegWit/Taproot, 32-44 char Base58 for Solana, and T-prefixed Base58Check for Tron. It then verifies checksums specific to each format.

What is ABI encoding and when do I need it?

ABI (Application Binary Interface) encoding converts human-readable function calls into hexadecimal calldata that the EVM understands. You need it when interacting with smart contracts directly, crafting raw transactions, or debugging contract calls. For example, an ERC-20 transfer encodes the recipient address and amount into a 68-byte hex payload.

How are Tron addresses derived from Ethereum keys?

Tron uses the same secp256k1 elliptic curve as Ethereum. A Tron address is derived by taking the raw 20-byte Ethereum address, prepending a 0x41 version byte, computing a double-SHA256 checksum, and encoding with Base58Check. The result always starts with the letter T.

What units does the converter support?

For Ethereum: Wei, Gwei, Finney, Szabo, and ETH. For Bitcoin: Satoshi, microBTC, milliBTC, and BTC. For Solana: Lamport and SOL. All conversions happen instantly as you type with full BigNumber precision.

What can the built-in RPC client do?

The RPC client queries EVM chains (Ethereum, Polygon, Arbitrum, Base, BSC) and Solana directly from your browser. For EVM: check balances, gas prices, blocks, transactions, and call smart contracts via ABI. For Solana: query slot, block height, accounts, balances, transactions, and rent exemption. Choose a preset chain or enter any custom RPC endpoint URL.

What are Blockchain Addresses?

A blockchain address is a unique identifier derived from a public key using cryptographic hash functions. Each blockchain uses a different derivation path and encoding scheme, but the core concept is the same: your private key generates a public key, and the public key is hashed and encoded into an address that others can use to send you assets.

Ethereum and other EVM chains use the last 20 bytes of the Keccak-256 hash of the public key, displayed as a 0x-prefixed hex string with EIP-55 mixed-case checksum. Bitcoin uses SHA-256 followed by RIPEMD-160 (hash160) with Base58Check or Bech32 encoding. Solana uses Ed25519 public keys encoded in Base58. Tron uses the same secp256k1 curve as Ethereum but encodes addresses with a 0x41 prefix and Base58Check.

Multi-Chain Address Formats

Chain	Format	Example Prefix	Curve
Ethereum/EVM	Hex + EIP-55	0x	secp256k1
Bitcoin P2PKH	Base58Check	1	secp256k1
Bitcoin SegWit	Bech32	bc1q	secp256k1
Bitcoin Taproot	Bech32m	bc1p	secp256k1
Solana	Base58	(varies)	Ed25519
Tron	Base58Check	T	secp256k1

Security Best Practices

Never share your private key. Anyone with your private key has full control over your assets on that chain.
Use test keys for experimentation. Generate throwaway keypairs with this tool for learning purposes only.
Verify client-side operation. Open your browser Network tab to confirm no data leaves your device.
Use hardware wallets for real funds. Browser-based key generation should never be used for storing significant value.
Validate addresses before sending. Always double-check chain detection and checksum verification before sending transactions.

Frequently Asked Questions

This tool supports Ethereum and all EVM-compatible chains (Polygon, BSC, Arbitrum, Base, Optimism), Bitcoin (P2PKH, SegWit P2WPKH, Taproot P2TR), Solana (Ed25519), and Tron (Base58Check). It also includes a built-in RPC client for querying Ethereum and Solana nodes. All operations run entirely in your browser.

This tool runs 100% client-side. No keys are transmitted to any server. Verify by checking the Network tab in DevTools. For maximum security, disconnect from the internet after loading, or use generated keys only for testing and learning.

P2PKH (starts with 1) is the original Bitcoin format. SegWit P2WPKH (starts with bc1q) reduces fees by ~40%. Taproot P2TR (starts with bc1p) uses Schnorr signatures for advanced smart contracts and improved privacy. Modern wallets default to SegWit or Taproot.

The validator checks prefix patterns: 0x + 40 hex chars = EVM, starts with 1/3 with Base58Check = Bitcoin legacy, bc1q/bc1p = Bitcoin SegWit/Taproot, T + 33 Base58 chars = Tron, and 32-44 Base58 chars = Solana. Checksums are then verified for each detected format.

ABI (Application Binary Interface) encoding converts function calls into hex calldata for the Ethereum Virtual Machine. The first 4 bytes are the function selector (keccak256 hash of the signature), followed by 32-byte ABI-encoded parameters. This tool encodes and decodes calldata for any function signature.

Tron uses the same secp256k1 curve and key derivation as Ethereum. A Tron address is derived by taking the 20-byte Ethereum address, prepending version byte 0x41, computing a double-SHA256 checksum (first 4 bytes), appending it, and encoding with Base58. Every Ethereum keypair has a corresponding Tron address.

The built-in RPC client lets you query EVM chains (Ethereum, Polygon, Arbitrum, Base, BSC) and Solana directly from your browser. For EVM chains you can check balances, gas prices, block data, transaction details, and call smart contracts via ABI. For Solana you can query slot, block height, account info, balances, transactions, and rent exemption. Choose a preset chain or enter any custom RPC endpoint.

Yes, for address generation, validation, unit conversion, and ABI encoding/decoding. Once JavaScript libraries have loaded, these features work without network access. RPC queries require a network connection to communicate with blockchain nodes, but no private data is sent — only public read requests.
