Citadel Dispatch CD194: SIDESWAP – LIQUID PREDICTION MARKETS
Date: March 9, 2026
Host: Matt Odell
Guest: Scott (Co-founder of Sideswap)
Theme: Actionable Bitcoin and freedom tech discussion with a focus on Sideswap, privacy, Liquid sidechain, confidential assets, and the future of prediction markets.
Episode Overview
This episode dives deep into Sideswap—a non-custodial wallet and swap platform built on the Liquid Bitcoin sidechain. Host Matt Odell and guest Scott, the co-founder of Sideswap, discuss the growth of the Liquid ecosystem, the unique features of confidential transactions and assets, the challenges of driving adoption, and the technical details and promise of Bitcoin-native prediction markets, all from a freedom tech perspective.
Key Discussion Points & Insights
1. Introduction to Sideswap and the Liquid Ecosystem
- [03:44]
- What is Sideswap?
- A non-custodial wallet for Liquid, enabling atomic swaps between assets like BTC, Liquid BTC (L-BTC), and Tether (USDT).
- Operates as a bulletin-board market where swaps are settled atomically and instantly between peers.
- Emphasizes true self-custody: “Your keys, your coins.” – Scott [04:52]
- What is Sideswap?
- Sideswap underpins swap functionality in several Liquid-supporting wallets, e.g. Aqua Wallet and Bull Wallet.
Notable Quote:
“We focus much on the tech and building out what we hope is a great product, liked by users. We don’t focus much on marketing, which is why you may not have heard of us much.” – Scott [03:14]
2. How Sideswap Works and its Order Book Model
- [04:52][06:12]
- Bridges Bitcoin main chain and Liquid sidechain by making peg-in/peg-out services easier and cheaper (0.1% fee).
- Enables swaps between L-BTC and assets like Tether and DEPIX (Brazilian stablecoin).
- Features a transparent order book (not a black box). Anyone can become a market maker—even from mobile. Dealer and CLI tools are open source.
Notable Quote:
“Order books where anyone can come in and improve prices ... any instant swap is essentially a market order into the order books.” – Scott [06:12]
3. Adoption Challenges and Growth in Liquid
- [12:31]
- Liquid's adoption is slow; lack of asset diversity and wallet support.
- Highlights importance of privacy—confidential transactions hide transaction amounts and asset types, making it hard for adversaries or chain analysis firms.
- Localized adoption: DEPIX drives growth in Brazil; Tether remains dominant in large transaction value.
4. Privacy & Confidential Transactions in Liquid
-
[14:23]
- Discusses how Liquid’s confidential transactions offer better privacy than Bitcoin or any EVM chain like Tron or Solana.
- Even Tether, when used on Liquid, can’t be selectively censored:
“USDT on Liquid ... due to the confidential transaction nature ... the issuer cannot confiscate the balance. They don’t know which UTXOs are USDT.” – Scott [17:52]
-
PayJoin transactions further mess heuristics and on-chain analysis, even with a small user base.
5. Why Tether Hasn’t Exploded on Liquid
- [16:57]
- Despite privacy advantages, Tether volume on Liquid is “absolutely nothing” (grossly outpaced by TRON and Ethereum).
- Liquidity on other chains is mostly with custodians; Liquid is pure self-custody.
- Liquid makes Tether much more censorship-resistant, but that’s not yet attracted major inflows.
Notable Quote:
“It’s a drop in the bucket ... much of the liquidity on the other chains is not really held in private wallets; it’s held with custodians.” – Scott [17:52]
- [19:58] PayJoin and swap-market transactions make analysis hard, especially when the peg-in/peg-out process further muddles UTXO linkage.
6. Prediction Markets: Liquid’s Unique Value Proposition
- [21:07][22:46]
- Odell laments lack of robust, private, Bitcoin-native prediction markets.
- Liquid’s privacy and self-custody mean prediction markets can be built more responsibly than on current popular chains like Polygon (Polymarket), where privacy is nearly non-existent.
- Competing projects on Lightning are mostly custodial and not sustainable.
- Sideswap is working to launch binary options and eventually full-featured prediction markets leveraging Liquid’s Simplicity smart contract language.
Notable Quote:
“Prediction markets ... you need the ability for people to participate anonymously ... if they work for intel or a government, they’re not going to do it unless they can do it anonymously.” – Odell [26:22]
7. The Oracle & Trust Model Problem
- [30:17][31:42]
- Explores how “solving the Oracle problem” (connecting real-world outcomes to on-chain contracts) is unsolvable, but can be pragmatically mitigated.
- Liquid’s federated model is discussed as a trade-off: it’s arguably as decentralized as, or safer than, Tron given current regulatory perceptions.
- Goal: be more decentralized and censorship-resistant than the exchange-custodied models.
Notable Quotes:
“I think the Oracle problem is unsolvable ... you can mitigate it ... for someone on chain to know what the weather was in Chicago yesterday, there’s gotta be a trusted third party.” – Odell [31:42]
8. Pragmatism in Custody/Decentralization & Liquid’s Place
- [33:09]
- Odell argues: If Tron is considered self-custody, Liquid deserves the same. The community is starting to accept different models at each network layer (on-chain BTC, Lightning, Liquid, etc.).
- Sideswap is built for non-custodial, orderbook-based swaps, but the federated peg remains a central discussion point.
Notable Quote:
“For bitcoin to scale ... you need these secondary layers ... there’s always going to be these different trade offs and discussions around how decentralized is it.” – Scott [34:40]
9. Building with Simplicity and Swaption MVP
-
[36:38][38:44]
- Sideswap launched Swaption: MVP binary outcome contracts using Simplicity, the new Liquid smart contract language.
- First use-cases: “Will Bitcoin price be higher/lower in X minutes?” and direction bets on % change.
- This is the first step towards real prediction markets with open order books, liquidity provision, and privacy.
-
Sideswap desktop and mobile wallets support cross-platform functionality; Swaption web connects to your wallet for order execution.
-
No KYC/AML required for participation.
-
[41:30]
- 50/50 revenue share for partners/wallets driving volume to Sideswap.
- Growing network effects, especially in Brazilian market (thanks to Deepix).
Notable Quote:
“The barriers to entry in Liquid are so low because anyone can issue assets and if you trade through Sideswap, there’s absolutely no gatekeeping at all.” – Scott [43:03]
10. Simplicity: Smart Contracts for Bitcoiners
- [43:49]
- Simplicity adds mathematically provable contracts to Liquid.
- Enables new financial markets, binary options, and more, with Bitcoin-native safety.
- Strict, conservative design philosophy—contrast with Ethereum’s error-prone and opaque contract model.
- Swaption is possibly the first live product using Simplicity; current users are experimenting with low-value trades.
Notable Quote:
“With Simplicity ... you have contracts which can be mathematically proven ahead of time so you actually know what you’re signing ... and you can create these binary outcome type of situations.” – Scott [43:49]
11. Call to Action for Freaks & Listeners
- [46:45]
- Scott urges listeners to: download Sideswap, experiment with Liquid peg-in/out, use the swap/order book, try Swaption, and get direct hands-on experience.
- No KYC/AML, low fees, better privacy.
- Liquid is much easier for transferring between Lightning wallets than Lightning itself—especially for larger amounts or balancing wallets.
Notable Quote:
“I'd love for people to just download the app and send a tractor amount of Bitcoin into Liquid and just play around with swaps. Just see what's possible ... do a few swaps back and forth, try the order books, go to swaption, just try these Simplicity contracts and just see where things are heading.” – Scott [46:45]
- Odell recommends Bull Wallet, Aqua Wallet, and Sideswap for experimenting with on-chain, Lightning, and Liquid swaps.
- Go to liquid.network (Mempool Space’s Liquid explorer) to analyze and understand privacy/post-swap activity.
12. Forward-Looking Predictions and Closing Thoughts
- [53:33][54:40]
- Sideswap aims to release a proof-of-concept (POC) full-featured prediction market within six months, building on their binary options experience.
- Next steps: refine order books for binary contracts, expand wallet connect features, and work with oracles.
Notable Closing Moment:
“Let's do something fun here ... if we have this update in six months, prediction wise, where are we in six months? ... I think we'll have the POC for it.” – Scott [54:26 – 54:52]
- Scott hints at ongoing experimentation with Satoshi Dice-style structures to stress-test Simplicity contract mechanics before launching larger-scale market mechanisms.

Memorable Quotes
-
On Liquid privacy:
"A lot of the probability analysis that Bitcoin chain surveillance firms do is based on amount correlation. And once you remove those amounts from being visible, it makes their job of detecting when ownership has changed hands much more difficult." – Odell [14:23]
-
On order book transparency:
“The order book thing is fascinating ... you actually have like a proper order book that basically anyone can participate in and become market makers ... more transparent pricing and theoretically I guess it should be better pricing.” – Odell [09:29]
-
On Bitcoin’s scaling and custody tradeoffs:
“So for bitcoin to scale, given that is a one asset chain, you need these secondary layers somehow since there's no solution yet exactly of how to create these exact or trustless two way pegs between the bitcoin main chain and a sidechain. There's always going to be these different trade offs ..." – Scott [34:40]
-
On Simplicity’s potential:
“With Simplicity you have contracts which can be mathematically proven ahead of time so you actually know what you're signing when you get yourself into it ... you can create options, futures, binary outcome contracts, etc.” – Scott [43:49]
Conclusion: Why This Episode Matters
This episode is a high signal, technical yet practical conversation focused on the real future of freedom tech in the Bitcoin universe. Odell and Scott provide both honest assessment and cautious optimism: Liquid—despite slow adoption and ongoing trust model debates—opens up compelling use-cases around privacy, self-custody, decentralized swaps, and possibly realizes the long-promised vision of robust, anonymous, Bitcoin-native prediction markets. The Sideswap team is quietly building foundational infrastructure during a bear market, and Scott makes a direct appeal for listeners to get involved and experiment, insisting that hands-on use is the best way to truly grasp the potential of these next-gen tools.
