Address Verification

Address verification is in Developer Preview. Endpoints and schemas are subject to change. To participate, contact Paxos Support.

Address verification confirms that a user or partner controls a blockchain address. Verified addresses can establish reward claim eligibility, unlock crypto withdrawals to private wallets for Paxos Global (PTE) customers, and support other compliance workflows.

The API represents each verification attempt as a verification record. A verification record is the API resource you create, retrieve, list, and complete. It confirms address control for the requested Paxos use case; it does not determine custody, title, or legal rights.

Verifying addresses through the Paxos Dashboard instead of the API? See Ownership Verification, as the Dashboard calls this flow.

How Verification Works

Paxos supports two API verification methods and an off-platform manual review path. Choose based on what the address holder can do, then follow the Verify an Address guide.

Method	When to use	How it works
`SIGNATURE`	The address holder can sign a message directly or through a wallet integration	Create a verification record, collect the signed message, then submit the signature via Submit Signature
`SMALL_DEPOSIT`	The address holder can send a transaction from the address but cannot sign a message	Send the exact amount specified in the response from the address under verification to a Paxos-controlled address
`MANUAL`	Additional verification requirements have not yet been automated	Contact Support for requirements. Manual review is handled off-platform and is not created through the public API.

Verification Lifecycle

Status	Meaning	Next step
`PENDING`	In progress	Poll Get Address Verification with the returned `id`. For `SIGNATURE`, submit the collected signature via Submit Signature. For `SMALL_DEPOSIT`, wait for on-chain confirmation or send again from the same address.
`APPROVED`	Address control confirmed	Done
`EXPIRED`	Verification window elapsed	Create a new verification and retry

API-created SIGNATURE and SMALL_DEPOSIT verifications expire after 48 hours. Check expires_at in the response and create a new verification if the window elapses. Manual review is handled off-platform and does not expire through the public API.

Supported Networks

All networks support both SIGNATURE and SMALL_DEPOSIT. The signing standard only applies when using SIGNATURE.

Network	Signing standard (SIGNATURE)

`ETHEREUM`	EIP-191 (`personal_sign`)
`INK`	EIP-191 (`personal_sign`)

`SOLANA`	ed25519
`XLAYER`	EIP-191 (`personal_sign`)
