Platform Components
Hinkal consists of three tightly integrated products.
Hinkal SDK
A developer-first toolkit that allows PSPs, payment processors, neobanks, OTC desks, and enterprises to embed universal confidential settlement directly into their existing infrastructure.
Private treasury and settlement flows
Confidential merchant payouts and payroll
Removal of wallet history and transaction linkage
Selective disclosure for compliance via viewing keys
All without changing custody, compliance processes, or routing logic.
Hinkal Pay
A lightweight application and SDK that enables confidential settlement using existing public wallets and supported chains (Solana, TRON, Ethereum and major EVM networks).
The only on-chain settlement infrastructure that keeps both the sender and the recipient confidential. When a transaction is executed through Hinkal Pay, funds are deposited into a confidential balance within the Hinkal smart contract, controlled by the recipient’s existing wallet.
The settlement is executed confidentially. Sender, recipient, and amount are not exposed on-chain.
Once funds are received on the confidential balance, recipient can:
Execute private payouts to vendors, affiliates, employees, partners, or treasury accounts Sender, recipient, and amount remain confidential on-chain.
Send funds to a public wallet address when needed The sender and the original settlement remain confidential.
Hinkal Pay integrates into existing payment flows without requiring new wallets, custody changes, or chain migration.
Hinkal Wallet
A self-custodial, multi-chain wallet with public and confidential accounts in a single interface.
The public account functions as a standard on-chain wallet. Users can buy tokens, swap, bridge, send, and receive assets.
Assets can be shielded into a confidential account.
From the confidential account, users can:
execute private-to-private transfers (sender, recipient, and amount remain confidential)
send funds to public wallet addresses (the sender remains confidential)
receive funds into a confidential balance
perform swaps and cross-chain transactions within the confidential account
Hinkal Wallet connects to decentralized applications in the same way as standard wallets.
The wallet demonstrates the capabilities of the Hinkal protocol.
