Hinkal

Hinkal now powers private swaps on HyperDEX, letting users trade 100+ tokens across supported chains with instant settlement and near-zero fees, plus built-in privacy. Both same-chain and cross-chain swaps are supported in a single flow.

• Backed by Hinkal's private-transaction layer, keeping swap details confidential.
• Extends Hinkal's privacy tooling further into Hyperliquid's ecosystem alongside its earlier HyperCore bridging feature.

Hinkal Pay now supports private bridging to HyperCore, letting users fund their Hyperliquid trading accounts privately and directly from their wallet balance. The feature sits under "Bridge and Send in One Go" in Quick Actions, with USDC on HyperCore selectable as the destination.

• The flow lets traders move funds onto the Hyperliquid network without exposing the transaction.
• Hinkal points to a blog post with more detail on the rollout.
• The launch extends Hinkal's private-transaction layer to Hyperliquid's chain infrastructure.

Hinkal has launched its Partner Portal, a program that lets third-party products add privacy through the Hinkal API and earn revenue on usage. Partners sign up, generate an API key, drop it into their API calls, set their own fee, and go live — earning on every transaction that runs through their key.

The portal positions the Hinkal API as an integration point for apps and platforms that want to offer private transactions without building the infrastructure themselves. Further details on eligibility and fee mechanics were not included in the announcement.

Hinkal is now live on Arc, adding privacy to stablecoin payments, settlements, and payouts on the network. Users can hold and spend private balances from their existing wallet keys, with senders, recipients, and amounts kept confidential, in what Hinkal describes as "compliant by design."

• The integration is available across all Hinkal products, including Hinkal Pay, Prime, and Wallet.
• Arc joins the list of networks where Hinkal's private-transaction layer is deployed, extending its "universal privacy for stablecoins" positioning.
• Hinkal points to a blog post with more detail on the rollout.

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.
