How this service works
opentools utility endpoint
Output
Returns the EIP-55 mixed-case checksummed representation of the provided Ethereum address, which encodes a checksum in the capitalization pattern of the hex characters to allow detection of mistyped addresses
Example use cases
Validate wallet address before transfer
“Before I send funds, can you checksum this Ethereum address to make sure it's properly formatted: 0xab5801a7d398351b8be11c439e05c5b3259aec9b?”
Normalize address for smart contract input
“I need to pass an Ethereum address into a smart contract call — can you convert 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae to its EIP-55 checksum form so it's safe to use?”
Check if address meets EIP-55 standard
“Is this wallet address already in valid EIP-55 checksum format, and if not, what should it look like: 0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359?”
