A valid address doesn’t tell you the receiving network.
“EIP-55 checksum passes” is a useful format result. It is not confirmation that a transfer will reach the intended recipient.
What the checksum actually checks
An Ethereum-style address contains 40 hexadecimal characters after 0x. EIP-55 derives a pattern of uppercase and lowercase letters from the address itself. ChainKit checks that pattern for mixed-case addresses, which can help catch a typing mistake. It also accepts lowercase and uppercase addresses as unchecksummed formats and labels that limitation.
A checksum is not a lookup. No blockchain is contacted. A correctly formed address might be unused, controlled by someone else, or unsupported by the service you intend to pay. A format checker cannot discover the intended owner.
Why Ethereum, Base and other EVM chains look alike
Multiple EVM networks use the same address representation. Seeing 0x therefore does not establish Ethereum mainnet, Base, BNB Chain, Polygon or another EVM network. It also does not prove which tokens an exchange or recipient will credit. Follow the recipient’s instructions for the exact asset and network.
ERC20 and TRC20 are not interchangeable instructions
A typical TRON receiving address uses Base58Check and starts with T. ChainKit supports that format separately from EVM addresses. If the recipient specifies USDT on Ethereum mainnet ERC20, do not substitute TRON/TRC20 just because the token symbol is also USDT. Network compatibility must be confirmed independently; ChainKit never converts a receiving address between networks.
Compare the whole destination
Two addresses can share the same beginning and ending while differing in the middle. Obtain the original through a trusted channel and compare every character. ChainKit’s comparison tool highlights differing positions. It ignores EVM letter case only after validating both inputs; TRON comparison is case-sensitive.
Try the checks privately
ChainKit runs these checks in your browser without an account, wallet connection or input upload. Built-in examples demonstrate the format checks without needing your real address. A standalone HTML download works offline. Do not paste private keys or recovery phrases.
