Get started in seconds — no signup required
The Base58 Encoder/Decoder converts data to and from Base58 encoding — a modified form of Base64 that removes visually ambiguous characters: zero (0), uppercase O, uppercase I, and lowercase l. Base58 was invented for Bitcoin wallet addresses and has become the standard encoding for cryptocurrency addresses, IPFS content identifiers (CIDv0), and distributed ledger applications. Base58Check adds a 4-byte checksum to detect transcription errors in manually entered addresses.
