How can you confirm on-chain that a transaction was really sent by you?
Bitcoin and Ethereum both use ECDSA signatures on the secp256k1 elliptic curve. Bitcoin also added Schnorr signatures with the Taproot upgrade.
Digital signatures use a pair of keys: the private key generates the signature, and the public key verifies it. The private key cannot be derived from the public key.
When managing your positions, the most important thing to remember is this: anyone asking you to provide your private key or seed phrase to “verify a signature” is trying to scam you. A genuine signature never requires you to hand over your private key.
