Atomix is a peer-to-peer trading dApp on Radix that settles trustless swaps of tokens and NFTs directly between two wallets, under the tagline "Trade Any Asset, With Anyone, At Anytime". It was built by Avaunt, the community developer behind the ShardSpace product family, and launched on mainnet on 30 October 2025 after a two-month public beta on Stokenet.

Each trade pairs two subintents – one signed by the buyer, one by the seller – so both legs of the swap finalize in a single atomic transaction or not at all. The platform's terms describe it as a "community-developed interface to pre-authorizations, commonly called sub-intents, a native feature on the Radix DLT network": Atomix never takes custody of user funds, and every settlement happens on-ledger from the user's own wallet. As of August 2026 the interface still carries a beta notice reminding users that real mainnet assets are at stake.

How it works

Over-the-counter trades normally force one side to move first and trust the other to follow. Atomix removes that ordering: the buyer's offer and the seller's acceptance are each expressed as a subintent, both parties sign in the Radix Wallet, and the ledger composes the two into one transaction. The assets are withdrawn and deposited simultaneously – if either leg cannot execute, nothing moves. The launch announcement summarized the guarantee as "assets exchange simultaneously or not at all", with no escrow component and no intermediary holding either side's tokens.

Discovery starts from any account address: a user can browse the assets held by any wallet and send the owner an offer to buy one of them, or pre-agree terms with a known counterparty and use Atomix purely as the settlement engine. There is deliberately no public order book – the developer has kept offers private and person-to-person so that OTC deals cannot be front-run or observed, positioning the open-auction use case in the sibling dApp Bullring instead.

Since a November 2025 manifest update, the transaction preview in the Radix Wallet shows the withdrawal and the deposit for both parties, so each signer sees the full result of the trade before approving it. The interface also flags recallable and freezable assets with safety warnings before a trade is signed.

Notifications and interface

An offer is only useful if the counterparty learns about it. Atomix delivers offers through Notix, Avaunt's Radix notification service, and through a dedicated Telegram bot for trade-offer notifications: if the recipient is a registered Atomix or Notix user, they are notified that someone wants to trade even when the offer arrives cold. Accepting works directly from Telegram – the accept button opens Atomix, the Radix Wallet opens to sign the subintent, and the trade executes.

The interface supports QR-code scanning for in-person swaps – scanning a counterparty's Radix Wallet account QR replaces copying addresses between devices – and multi-account support, with Telegram notification settings configurable per account.

Developer API

Atomix exposes its trade engine to third-party sites. A developer registers an app in the My Apps section, generates an embeddable widget with the widget generator, and follows the bundled integration guide. The integration POSTs the trade details to the Atomix API, which returns the composed transaction manifest for the user's wallet to sign – letting any site sell digital assets from its own front end while Atomix handles subintent construction and settlement. The developer built a demonstration third-party dApp against the API as part of internal testing.

Fees and settlement on ledger

Atomix charges 3% of the trade price, and it charges it on ledger. Every settlement routes the fee to component_rdx1cq94mg7…y9050mvz, a component whose on-ledger metadata names it "Atomix Fee Collection", tags it atomix, sub-intents and OTC, and points back at the Atomix dApp definition account. The rate is visible in the amounts themselves: 0.3 XRD on a 10 XRD trade, 3 on 100, 30 on 1,000. That makes the component a public meter of the dApp's use, which no status code and no front end can give you.

Walked in full on 28 August 2026, it holds 52 transactions reaching back to 24 October 2025, a week before the mainnet launch. Across 40 fee events from that date to 17 January 2026 it collected 208.38 XRD in total, the largest single fee being 30.6 XRD, on a trade of about 1,020 XRD. Then it went quiet for seven months.

It came back on 21 August 2026 with three transactions in forty minutes, and the middle one is the largest trade Atomix has settled: the sale of the Avaunt Staking validator's owner badge for 1,456,311 XRD, on which the fee was 43,689.33 XRD. That one fee is 210 times everything the platform had earned in the ten months before it. Twenty minutes later the operator swept the component's whole balance, 43,693.83 XRD, in a single withdrawal. Avaunt built Atomix, and when Avaunt sold its validator it used Atomix to do it.

History

Atomix surfaced on 1 September 2025, when Avaunt announced the Stokenet beta at atomix.fly.dev and invited the ShardSpace community to test it. The two months that followed were a public hardening pass:

Atomix is one of four products built by Avaunt, the operator of the Avaunt Staking validator: ShardSpace (portfolio management), Notix (notifications), Atomix (peer-to-peer OTC trading) and Bullring (peer-to-peer auctions). Atomix and Bullring both build on subintents – Atomix for private direct offers, Bullring for open listings with reserve prices. Support and development discussion for the whole family runs through the shared ShardSpace | Notix Community Telegram group.
