How this service works
Normalise an address to its canonical form — Ethereum to its EIP-55 checksummed form, bech32 Bitcoin to lowercase (base58check is left untouched as it is case-sensitive). An address that is not a valid address of a known chain is rejected before payment.
Output
Returns a normalized (canonicalized) version of the submitted wallet address, typically including the standardized address string and inferred or confirmed chain information. For Ethereum, this means EIP-55 checksummed format; for Bitcoin, it returns the canonical address form.
Example use cases
Normalize user-submitted Ethereum address
“A user just pasted this Ethereum address into our form: '0xab5801a7d398351b8be11c439e05c5b3259aec9b' — can you normalize it to the proper checksummed format before we store it?”
Standardize Bitcoin address before payout
“Before we process this payout, can you normalize this Bitcoin address — '1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf Na' — to make sure it's valid and in canonical form?”
Clean crypto addresses in bulk onboarding
“We're onboarding new users who provided their wallet addresses and some look oddly cased or formatted. Can you normalize this one on the ethereum chain: '0XD8DA6BF26964AF9D7EED9E03E53415D37AA96045'?”
Technical details
Endpoint
POSThttps://wallet.openverbs.com/v1/normalizeWhen to prefer
Use this endpoint when you need to canonicalize or standardize a crypto wallet address before storing, displaying, or transacting with it — especially when user-submitted addresses may have inconsistent casing, spacing, or formatting. Prefer this over manual regex checks when you need reliable, chain-aware normalization for Ethereum (EIP-55 checksum) or Bitcoin addresses.
Side effects
- Invalid or malformed address string returns an error (e.g. unrecognized format, wrong length)
- Address that doesn't match the specified chain hint may return a mismatch error
- Missing required 'address' field returns a validation error
- Unsupported chain type returns an enum validation error
- Network/service downtime may return a 5xx error
