Private by defaultBuilt on NEAR

Sealed.

The privacy protocol for sending any crypto to any X account. They sign in with X to open it. Built on NEAR.

Check your @

Send crypto to any @. · Any coin. Any chain. Any @. · Stop asking for their address. · Settled privately on NEAR Intents.

How it works

  1. Step 1

    Type an @

    Any X account. We look up its permanent ID, and NEAR Chain Signatures give it an address on every chain.

  2. Step 2

    Send from any wallet, on any chain

    Bitcoin, Ethereum, Base, Solana and more, settled cross-chain through NEAR Intents. No need to ask for an address.

  3. Step 3

    They sign in with X to open it

    The money waits in their confidential balance on NEAR until they sign in. No expiry.

Confidential sends

Send private money to any @.

When you send in the app, your payment settles through NEAR Intents into a confidential balance on NEAR's private layer. The chain you paid from shows that you paid; it does not show who the money was for.

The recipient's balance and activity are never shown on their page or anywhere else. Only they can see them, after signing in with X.

Read the trust model

Any coin. Any chain. Any @.

Send from any of these. They receive into one private balance.

The protocol

Privacy protocol, built on NEAR

Every piece is public NEAR infrastructure or code you can check on-chain.

How it works What you are trusting

Your @ already has a wallet. You just haven't opened it.

Sign in with X to see what's been sent to you. Read-only access: we never post.

Questions

Do they need to sign up?

No. Every X account already has deposit addresses the moment we calculate them from its permanent X user ID. They only sign in with X when they want to use what you sent.

Can anyone else take the money?

Only someone who can sign in to that X account. The sign-in is checked inside secure hardware, and the vault contract only signs for the matching account. We, the operators, have no way to move anyone's funds.

If someone takes over the X account before the owner secures it, they could open the wallet. That is why owners are asked to add their own key right after they first sign in.

What if they never open it?

It stays theirs. There is no expiry, no clawback and no return to the sender.

What is visible publicly?

Your payment into NEAR Intents, the private settlement layer, is visible on the chain you paid from, and so is any later withdrawal out of it. Who the money was for and their balance are not shown to anyone but the owner. Until an owner adds their own key, the amounts they move out of their balance are visible on NEAR, because the contract checks their limits in public. Private is not the same as anonymous; see the trust model.

Which coins and chains?

  • Arbitrum: ETH, USDC, USDT
  • Robinhood Chain: ETH
  • BNB Chain: BNB, USDC, USDT

What are the fees?

Receiving is free. When you withdraw, 0.75% is taken: a 0.50% service fee on what you received and 0.25% for the withdrawal. Swaps inside your private balance pay only the network. Every quote shows the full breakdown before you confirm.

Can I get my money back if I sent to the wrong @?

No. Once funds are credited to an account they belong to it. Always check the profile card (picture, name, followers, account age) before sending. If a payment fails before it is credited, for example because the quote expired, it is refunded to your wallet automatically.
