How this service works
Validate a crypto address offline: format and checksum for EVM EIP-55, Bitcoin, Litecoin, Tron, XRP, Solana, TON, Sui, Cosmos and Cardano, with network detection.
Output
A JSON object containing the original address, a boolean valid flag, a boolean checksum_failure flag, a verdict string summarizing the assessment, an array of matching blockchain networks, a short summary string, a note with caveats or context, and a source field indicating data provenance. All validation is performed offline without network calls.
Example use cases
Validate withdrawal address before payout
“Before I send funds, can you validate this withdrawal address and confirm it's a properly checksummed EVM address: 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe?”
Detect network for unknown address
“I have this crypto address and I'm not sure what blockchain it's for — can you figure out the network and tell me if the format is correct: TNPeeaaFB7K9cmo4uQpcU32zGK8G1NYqeL?”
Verify Cardano address before DeFi interaction
“Can you verify that this Cardano address is valid before I use it in a smart contract: addr1qx2fxv2umyhttkxyxp8x0dlpdt3k6cwng5pxj3jhsydzer3jcu5d8ps7zex2k2xt3uqxgjqnnj0vs68szgafdrqgkq8t5scnk?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/crypto/address-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, offline, multi-chain crypto address validation without making on-chain RPC calls. It is ideal for pre-flight checks before sending payments, sanitizing user-submitted wallet addresses, or determining which blockchain network an address belongs to. It covers the major chains (EVM, Bitcoin, Litecoin, Tron, XRP, Solana, TON, Sui, Cosmos, Cardano) in a single call, making it preferable over chain-specific validators when the network is unknown.
Side effects
- Missing required 'address' query parameter returns an error
- Completely unrecognizable string format returns valid=false with no matches
- Partial or truncated addresses may return valid=false even for real networks
- Mixed-case EVM addresses with wrong checksum return checksum_failure=true
- Non-standard or newer blockchain address formats not in the supported list return no match
