Privacy comes to Monad with Unlink

Public blockchains record activity on a shared ledger open to everyone. That openness is part of what makes settlement verifiable and trustworthy. However, it also means the details of an organization's onchain activity, including its balances, counterparties, and the timing and size of its transactions, are exposed to the public.

For an institution, that visibility carries a cost. A fund rebalancing a portfolio, a trading desk managing positions, or a company running payroll cannot operate on infrastructure that publishes the parts of its business meant to remain confidential. An address exposes position sizes, a transaction history can reveal strategy, and a single payment discloses both a counterparty and an amount. For any operator moving meaningful volume, that exposure is a reason to keep onchain activity limited.

Unlink addresses this, and it is now live on Monad.

What gets exposed, and why it matters

Putting capital onchain can reveal far more than the details of a single transfer. From an address alone, an observer can identify which markets a desk supplies into, how much sits in each position, and how those allocations shift over time. Position sizes indicate conviction and reallocations indicate a change of view, which together expose the kind of strategy a firm would ordinarily protect. For an institution, that level of visibility is a competitive liability.

The common response has been to move activity onto a separate private chain. That removes the exposure and introduces a different problem. Capital on an isolated network loses access to the liquidity, the markets, and the composability that made going onchain worthwhile in the first place. One constraint gets traded for another.

How Unlink works

Unlink is a privacy layer that deploys as a smart contract on Monad. There is no separate chain and no bridge. Users deposit ERC-20 tokens into the Unlink contract, hold balances as encrypted notes, and move value between private accounts using zero-knowledge proofs. The contract verifies each operation without learning the sender, the recipient, or the amount of a private transfer.

Builders integrate through an SDK built around four operations: deposit, transfer, withdraw, and execute. Transfers between private accounts keep all of their details hidden. The execute operation lets a private balance fund an action on an external contract, such as supplying to a lending market, without tying that activity back to a public wallet. Integrations can run non-custodial or custodial, with keys held in the user's browser or a server holding accounts on the user's behalf.

Privacy on its own does not clear the bar for institutions, which is why Unlink is built to produce scoped audit views. A finance team, a compliance function, or an external reviewer can be granted visibility into the records they need without the full account graph becoming public. Confidentiality and the ability to report live in the same system.

Why this belongs on Monad

Unlink works on Monad for the reason most EVM infrastructure does. Monad is fully EVM compatible, so Unlink extends the contracts, tooling, and liquidity that already exist on the chain rather than asking anyone to rebuild somewhere new. Privacy becomes a property that capital can carry into the existing economy instead of a reason to leave it.

That is the difference that matters. Capital routed through Unlink keeps access to what is already live on Monad: Aave, Morpho, Uniswap, and Curve, with $350M in TVL alongside tokenized assets and more than 30 fiat on and off ramps. A position can stay private and still be supplied, borrowed against, traded, and settled across that economy. Composability is preserved, and privacy is added around the activity rather than walling it off.

Privacy usually comes at the cost of performance. The cryptography behind private transactions is computationally heavy, and many privacy-preserving systems throttle throughput sharply as a result. Building on Monad changes that trade-off. A chain that delivers 10,000 TPS, 400ms block times, and near-zero fees gives a privacy layer enough headroom to operate without passing a performance or cost penalty on to the people using it.

A separate private chain cannot offer that. It is the combination of performance, composability, and now privacy on one EVM chain that lets capital arrive, stay, and do something once it is here.

A foundation for what comes next

Going live is the first step. Private accounts and private transfers on Monad are the base layer, and the same model extends in two directions that matter for the economy Monad is building.

The first is private DeFi. Through the execute flow, a private balance can supply to a lending market, allocate across vaults, or rebalance a position without tying that activity to a public identity. Capital can do something on Monad without broadcasting the strategy behind it.

The second is payments. Payroll, vendor payouts, treasury movement, and business-to-business settlement all depend on keeping amounts and counterparties confidential. These are the flows that have stayed off-chain precisely because a public ledger broadcasts them. A privacy layer on a chain that already has this liquidity and live payment rails is what makes them workable onchain.

Money moves on Monad. With Unlink, it can move privately, and it keeps everything else the economy makes possible once it arrives.

About Monad

Monad is a high-performance, institutional-grade Layer 1 blockchain built to power the financial layer of the internet. Fully EVM-compatible, Monad delivers 10,000 TPS, 400ms block times, 800ms finality, and near-zero fees, without requiring specialized hardware. The network runs on consumer-grade machines, supporting accessible participation and decentralized network operation: over 200 independently operated validators across 30+ countries and 55+ cities secure the chain today.

About Unlink

Unlink is a privacy layer for public blockchains that lets institutions and businesses hold, move, and use capital onchain without exposing balances, counterparties, or transaction history. It deploys as a smart contract on the chains teams already use, with no separate network and no bridge, and uses zero-knowledge proofs to keep transfers private while producing scoped audit views for compliance and reporting. Built for fintechs, payment processors, and treasury teams, Unlink supports private payments, treasury operations, and private DeFi through a single EVM-compatible SDK.
