Hinkal

Hinkal is now integrated into the WDK (Wallet Development Kit) by Tether, letting developers add privacy to wallets and apps built on the kit. Users can send stablecoins and other assets with the sender, recipient, and amount kept private, with Hinkal pointing to a blog post with more detail on the integration.

Hinkal is now live on Robinhood Chain, the Arbitrum-built Layer 2 designed for tokenized real-world assets such as Stock Tokens, announced via the protocol's X account. The integration spans Hinkal Pay, Prime and Wallet, letting users hold assets in a private balance without exposing their full portfolio on-chain and swap privately.

• Hinkal points to a blog post with more detail on the rollout.
• The launch extends Hinkal's private-transaction layer to Robinhood's L2 infrastructure for tokenized RWAs.

Hinkal has partnered with Vanar Chain to bring private stablecoin payments to AI organizations. Every AI organization launched through Vanar Foundry runs its own USDC treasury on Base, where client payments and backer funds flow in; Hinkal adds privacy to those flows, letting the treasuries receive and transact without exposing balances or sender/recipient on-chain.

Hinkal has partnered with Avvio, making its private-transaction layer live inside Avvio's banking app — a move that turns Avvio into a private neobank where enterprise clients can hold private balances and make confidential payouts without exposing sender, recipient, or amount on-chain. Users can shield and unshield funds, send private transfers, and receive money privately via Hinkal Deposit Addresses from within the same interface, with no separate app or account.

Hinkal announced it completed an independent security review by Quantstamp of its core protocol, covering its smart contracts and Circom zero-knowledge circuits. The report is part of Hinkal's ongoing security hardening across its privacy infrastructure — the latest in a series of checks that also includes its bug bounty program on HackenProof.

The audit targets the same components that underpin Hinkal's shielded pool, private balances, swaps and payments. Hinkal described the review as an important step in maintaining a rigorous security standard across its privacy layer.

Hinkal now lets users withdraw funds directly from centralized exchanges into a private account on-chain, with no integration required. The protocol generates an EOA linked to the user's private account in the shielded pool, so moving money off a CEX no longer exposes their transaction history on-chain.

Hinkal has since introduced Deposit Addresses, which remove the need for the sender to interact with smart contracts when funding a private balance. This makes CEX withdrawals, PSP payouts, transfers from custodial wallets, and simple person-to-person payments into a private account straightforward, broadening how users can receive funds privately.

Hinkal's X account posted a "Deals of the Week" roundup covering Aug 30 – Sep 5 with 11 deals, framing the week as one where banks moved from lending against crypto to issuing on top of it. The headline item: 21 banks — including BofA, Citi, Goldman Sachs, UBS, Deutsche Bank and Santander — are forming a joint company to issue a token.

Hinkal's X account shared a roundup of 22 stablecoin stories from Aug 31–Sep 4, highlighting three it calls significant. The BIS argued tokenised deposits will beat stablecoins in payments, TD finished its work in a tokenised-deposit interoperability test, and 21 banks including BofA, Citi and Goldman Sachs were named for rollout in 2027. Tether's CEO pushed back within a day, and stablecoin yield was a running theme.

Hinkal was accepted into the XDCFoundation AI Agents & Blockchain Accelerator, run in partnership with Plug and Play Tech Center. The program connects emerging Web3 protocols with traditional-market enterprises. Hinkal says AI agents will need more than payments — they'll need infrastructure that can move value privately and compliantly, which fits its private-transaction layer.

Hinkal has opened a bug bounty program for independent security researchers through HackenProof, offering rewards of up to $10,000 for critical vulnerabilities. The scope covers Hinkal's core smart contracts and zero-knowledge circuits, spanning private balances, transfers, swaps, and payments.
