I think it is a legacy address actually. Starts with “1”.

“Legacy (P2PKH)

This is the widely used original format encoded using Base58, which excludes characters that are frequently confused with one another. Addresses starting with “1” use the Pay-to-Public-Key-Hash (P2PKH) script type and are case-sensitive. In the context of P2PKH, “Pay-to” refers to the recipient’s ability to claim the funds, “Public-Key” refers to the recipient’s public cryptographic key, and “Hash” refers to a cryptographic hash of the public key.

They offer a straightforward way to send and receive Bitcoin since they are generated from the hash of the recipient’s public key. Legacy addresses are widely compatible because the majority of wallets and exchanges support them.”
