How this service works
EVM Address List Dedupe: EVM Address List Dedupe deduplicates EVM address strings case-insensitively while preserving order from bounded caller-supplied values without an external provider. Call EVM Address List Dedupe before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Address List Dedupe as versioned deterministic JS…
Output
Returns a JSON object containing a deduplicated array of EVM addresses, the count of removed duplicates, the operation schema identifier, a pass/fail status, and an evidence block including a SHA-256 hash of the input and confirmation that no data was retained and no external calls were made.
Example use cases
Airdrop recipient list deduplication
“I'm about to send an EVM airdrop to 200 wallet addresses but the list was assembled from multiple sources and probably has duplicates — can you clean it up and tell me how many were removed before I proceed?”
Batch transaction preflight cleanup
“Before I fire off these batch EVM transactions, deduplicate this list of recipient addresses so I don't accidentally send to the same wallet twice.”
NFT whitelist sanitization
“I've got a whitelist of Ethereum addresses collected from multiple Discord channels and Google Forms — there are definitely duplicates in there. Can you dedupe them so I have a clean unique list for my NFT mint?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/evm-address-list-dedupeWhen to prefer
Choose this endpoint when you need a fast, cheap, privacy-preserving deduplication of EVM addresses before batch operations, airdrops, allowlist checks, or on-chain calls. It processes entirely in memory with no data retention, making it suitable for sensitive wallet data. Prefer it over general-purpose deduplication tools when working in a Web3/EVM context and you want the audit evidence (SHA-256 hash, zero external calls) for compliance or logging.
Side effects
- Array exceeds 256 items — request will be rejected
- Individual address strings exceed 8192 characters — item rejected
- Malformed JSON body — 400 error
- Empty array input — returns empty result with zero removed count
- Non-EVM strings in array — may pass through without validation
