A 0x01 byte appended if the key is intended for a compressed public key . wallet import format (wif)
WIF keys are distinguishable by their length and starting characters, which indicate the key's type and intended network: (Essential, but not for daily use) A 0x01
In conclusion, Wallet Import Format is more than just a string of characters; it is a foundational piece of cryptocurrency infrastructure designed to humanize cryptographic complexity. By introducing versioning, compression flags, and error-checking checksums, WIF mitigated the risks associated with raw private key management. While modern wallets have evolved to use more intuitive mnemonic seeds, WIF remains the enduring standard for the portability of individual keys, standing as a testament to the early engineering solutions that made the secure self-custody of digital assets possible for the average user.
