Check crypto addresses.
Convert token amounts.
Check EVM and TRON address formats, compare full addresses, convert token units and split amounts exactly.
Every tool is free, and your inputs stay in this browser.
Check an address
Catch format mistakes and checksum errors before opening your wallet.
Compare every character
Matching the first and last few characters is not enough. Compare a destination against a trusted address.
Token units, without rounding
Convert a token amount to its smallest units, or turn an integer from a transaction into a readable amount.
Split an amount precisely
Divide a token amount into equal shares and account for every last unit. Useful for shared expenses and payout planning.
Useful tools should be easy to reach.

Convert 1.25 tokens into 1,250,000 units.
For a token with six decimal places, the conversion is exact: 1.25 × 1,000,000 = 1,250,000 smallest units. This is arithmetic, not a lookup of a real token.
- Choose the Token units tab and Token amount → smallest units.
- Set decimal places to 6, enter 1.25, and choose Convert exactly.
- Expect 1250000. In the reverse direction, the same integer and decimal setting produce 1.25.
Verify the decimal setting against the exact token contract and network. ChainKit does not fetch balances, determine token decimals or submit transactions.
Three things to confirm.
- The recipient. Obtain the address through a trusted channel, not a lookalike entry in your transaction history.
- The asset and network. Both sender and recipient must support the same token on the same network. An EVM address alone cannot identify that network.
- The full destination. Compare every character and check the final confirmation in your wallet. Consider a small test transfer when appropriate.

Clear answers. Clear limits.
Does a passing check mean an address is safe?
No. ChainKit validates address syntax and checksums. It does not query blockchains, check balances, identify scams, verify who controls an address, or verify an exchange’s deposit support. Ethereum/EVM and TRON Base58Check are supported; Bitcoin, Solana, ENS names and payment URIs are not.
Where does my data go?
Tool inputs stay in this tab’s memory. Tool input is never uploaded. Optional anonymous action counts are sent only after permission; no cookies or visitor IDs. Measurement details. The hosting provider may log ordinary page and asset requests. Clicking an external reference opens that other site. Reloading clears your inputs.
Why is ChainKit free?
This is an independent First Fold project supported by voluntary donations. Every feature works without paying. Donations do not buy a service or guarantee future features.
Can I use it for a real transaction?
Use it as one check alongside your wallet and the recipient’s instructions. It does not connect to wallets, create transactions or sign anything. These utilities are not a guarantee against financial loss.
Which standards does it use?
Ethereum case checks follow EIP-55. TRON checks follow its Base58Check address format. Hashing uses noble-hashes and encoding uses scure-base. QR codes contain the address only; select the network yourself.
