The probability of two users generating the exact same private keys is extremely low, but not impossible. This is the only explanation I could think of considering that you never used or exposed your wallet to some vulnerabilities or exploits.

There are 2^160 Ethereum addresses. That’s 1 followed by 48 zeroes. There is no chance in this universe that a genuine collision happened. I’d rather believe that @cassie broke prime factorization and is secretly draining our wallets Or that @farcasteradmin.eth was the victim of a much more mundane but sly attack

Per the birthday paradox, assuming all addresses are equally likely to occur (which theoretically, it should be), the likelihood of any two collisions occurring is 50% when about 1.42*10^24 addresses are generated. This is why I put it as the least likely scenario, because it’s highly improbable, but not impossible.

Our universe exists because of smaller than that probabilities happening every day. not that there might have been a collision, not at all, just pointing out probabilities are counter intuitive to our human experience and lifespan.

Two caveats: - The best discrete log algos result in n/2 bits of security, so addrs have ~80 bits of security - Since keys are 256 bits there's 2^96 keys per address, and you only need an address collision, not a key collision There's been research into how to extend address space to 256 bits partly because of this :)
