0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359A valid format does not mean the address belongs to the right person. It only means the address is well-formed. Compare the whole address with the source and send a small test amount first.
FAQ
What is an EIP-55 checksum address?
The same 0x address with some letters in upper case. Which letters is decided by a Keccak-256 hash of the address, so a changed character almost always breaks the pattern.
Does EIP-55 change the address?
No. Upper and lower case are the same address. The case only adds a check against typos.
Does it work for BNB Smart Chain, Polygon and Arbitrum?
Yes. Every EVM chain uses the same address and the same EIP-55 rule.
