Xythum Labs

darkpool based decentralized aggregation layer

[Xythum Labs @XythumL]

At Xythum Labs, we're solving the privacy trilemma balancing offchain and onchain privacy, DeFi composability, and compliance. users get fully shielded private asset management through threshold-encrypted UTXOs, (with Notes for internal balances and Memos for programmable transfers like atomic swaps), all while connecting to public DeFi via composable adaptors that verify proofs and execute callbacks atomically. We've got a decentralized solver network planned to handle private settlements with recursive ZK proofs, keeping things liquid and MEV-resistant. For compliance, weighted threshold encryption on the ciphertexts lets users decrypt their own notes solo, but requires a t-of-n quorum for any authorized access via onchain proposals.

For offchain privacy, we are implementing a Sphinx-style mixnet of relayers to hide IP metadata and sponsor fees privately, alongside PIR-based queries with OPRF for wallets (stateless) to detect memos without exposing viewing keys or patterns.

Every transaction you've ever made is public. Forever.

That NFT you minted in 2021.
The memecoin that took 80% of your life savings.
The wallet you thought was clean.
That offramp to your favorite Cex.

Ethereum remembers everything.

The chain is just the surface. Most identification never touches the blockchain. Your IP, browser fingerprint, trade timestamps, the canvas hash linking your wallets to one machine. Infrastructure services and chain analysis firms correlate all of it back to you.

Hisoka helps protect your activity at every layer.

happy new year to y’all

3rd Place: @XythumL 🥉

Xythum Labs is building a privacy-preserving dark execution layer for cross-chain settlement, designed to eliminate MEV, front-running, and orderflow leakage.

Xythum won the Startup Pitch Finale at the @Algo_Bharat India Summit.

It shows that privacy and encrypted execution actually matters.

Thanks to @Algo_Bharat @AlgoFoundation @StaciW_DC @niikkhhiil @anilk_kakani @marcvl for the platform, and the insanely sharp conversations.

We are just getting started.

[The Core @the_core_in]

🏆 The winner of @Algo_Bharat Startup Pitch Competition Grand Finale — The Marlin Tank is Ravi Shankar of @XythumL (Hyderabad).

What they do: Xythum provides an encrypted, privacy-first infrastructure layer that enables high-speed, confidential execution for smart contracts and cross-chain operations.

Congratulations to the team on building the next generation of on-chain security!

And that’s a wrap from the @AlgoFoundation India Summit 2025!

As crypto reaches more mainstream users, the need for privacy is more urgent than ever.

[Xythum Labs @XythumL]

Xythum was at @avax Team1 Pitch Day in Goa ⚡️

We showcased our privacy-perps DEX, marking the first public demo of Xythum’s privacy layer on avax.

The energy was unmatched, with builders, KOLs, and ecosystem leads all in one place.

Wrapped up with a great discussion on privacy in DeFi (Xythum cooked)

Big shoutout to @AvaxTeam1, @Avalanche_In, @MittalDevika, @0xSarnavo, @shriyashpandit, @JohnNahas84, @vamsii for curating a platform that truly backs builders

Xythum is Avax-pilled 🔺

[Xythum Labs @XythumL]

Exchange hacks target specific wallets after analyzing on-chain wealth.
The $600M Ronin hack started with on-chain analysis identifying the richest addresses.

Transparency shows them exactly what to steal.

What's the solution?

Xythum.

[Xythum Labs @XythumL]

Front-running used to require insider information. Now it just requires watching the mempool. We democratized extraction by making all information public.

The result? Sophisticated actors profit while regular users subsidize them through worse execution.

[Xythum Labs @XythumL]

Xythum will be pitching here!

[Avalanche Team1 @AvaxTeam1]

Avalanche India Pitch Day - Goa 🇮🇳

The Team1 India hackathon tour across 7 cities will now culminate in Goa next week and top projects will pitch to a panel including Ava Labs BD.

Our goal is to find talent, invite them to build on Avalanche and then support their journey from idea to product.

Excited to collaborate with Ava Labs & @MittalDevika on this 🔺

[Xythum Labs @XythumL]

Privacy unlocks true operational security.

With complete anonymity, companies can seamlessly maintain hot and cold wallets without revealing connections between them.

Traders can execute distinct strategies across multiple addresses, each one isolated and untraceable.

Every user gains the power to compartmentalize risk exactly as they need, without compromise.

[Xythum Labs @XythumL]

Transparent-only blockchains make basic business impossible.

Imagine running payroll where every employee sees what everyone makes. Negotiating deals where suppliers know your exact budget. Competing where rivals watch your every move. This is the current state of blockchain commerce.

HTTPS took 20 years to become default. Started as optional, became recommended, then Chrome began marking HTTP sites as "not secure" and adoption went vertical.

Privacy layers for blockchain will follow the same path.

[Xythum Labs @XythumL]

Xythum Dark Pools unlock privacy at scale.

While other protocols fragment users into separate mixing pools on individual chains, Dark Pools unite all private transactions in one place.
This creates an anonymity set measured in millions rather than hundreds.

Privacy becomes a network effect, growing stronger with adoption.

[Xythum Labs @XythumL]

No more address anxiety when transacting. No more fear of revealing holdings. No more complex operational security. Privacy makes blockchain as simple to use as traditional payment systems.

Xythum.

[Xythum Labs @XythumL]

Privacy enables genuine decentralization. No need for centralized exchanges for opacity.
No custodians required for security. Privacy eliminates the centralized workarounds transparent chains require.

[Xythum Labs @XythumL]

Privacy multiplies the value of everything else in DeFi. Lending rates become efficient when whales can't be targeted. DEX liquidity deepens when large trades don't leak early. Stablecoins become usable when balances stay private.

Privacy makes markets work the way markets are supposed to work.
