Prepaid KYC Deposit

(Soon to be deprecated) Please checkout the APIs in the Partner Payments section instead.
The Prepaid KYC Deposit API allows partners to notify the system about funds deposited into their prepaid KYC account. Once verified, these funds are credited to the partner's balance for future KYC operations.

Signature Generation
The base64Signature field is essential for verifying that you are the rightful owner of the transaction. To generate this signature:

Use the same private key/wallet that initiated the blockchain transaction

Sign the transactionHash value as the message

Encode the resulting signature in Base64 format

You can generate this signature using a publicly available, open-source tool: Solana Message Signer

This security measure prevents unauthorized users from claiming deposits made by others and ensures that only legitimate deposit claims are processed.

Complete Deposit Process

Get Deposit Instructions

GET /transformer/utility/prepaid/kyc/balance

Note the network, currency, tokenAddress, and toWalletAddress from the response.

Make the Deposit

Send funds to the specified toWalletAddress using the correct blockchain network

Use the correct token as specified in the deposit instructions

Save the transaction hash from this transaction

Generate Signature

Use the same wallet/private key that initiated the transaction

Sign the transaction hash as a message

Encode the signature in Base64 format

You can use the publicly available Solana Message Signer tool for this step

Notify About the Deposit

POST /transformer/utility/prepaid/kyc/deposit

Include both the transaction hash and the Base64 signature in the request body

Verify the Deposit

Check the response to confirm the deposit was successful

You can also call the Prepaid KYC Balance API again to verify your updated balance

Usage Notes

Each transaction hash can only be used for a single deposit. Attempting to reuse a transaction hash will result in a 400 Bad Request error.

The deposit amount credited is determined based on the actual amount transferred in the blockchain transaction.

After a successful deposit, your prepaid balance can be used for KYC submissions without including a transaction hash in each submission.

The signature verification ensures that only the rightful owner of a transaction can claim the deposit, preventing fraudulent claims.
