about this tool
Check whether an Ethereum address is valid and convert it to the EIP-55 mixed-case checksum format. Catches typos before they cost you.
good to know
what is an eip-55 checksum?
the address with some letters uppercased according to keccak256 of the lowercase address. wallets use it to catch typos: a single wrong character almost always breaks the casing.
is a lowercase address wrong?
no. all-lowercase and all-uppercase addresses are valid, they just carry no checksum. mixed case that does not match the checksum is a red flag.
does the checksum work across chains?
eip-55 is the same on every evm chain. a few chains (rsk) use a chain-specific variant (eip-1191), which this does not apply.
