  • Fedimint now runs on Android phones, letting any group form a federated bank.
  • This model gives AI agents a custodial sandbox with a human-operated 'undo button'.
  • Developers see AI agents bypassing apps, interacting with crypto via conversational commands.

Federated custody is making Bitcoin self-custody as simple as scanning a QR code with a spare phone. On Citadel Dispatch, Fedimint developer Justin revealed the project’s guardian software now runs on Android, turning everyday devices into the hardware for a community-controlled bank. This bypasses the need for specialized node hardware, lowering the barrier for small groups to collectively secure their bitcoin.

Justin, Citadel Dispatch:

- Justin sees eCash as well-suited for AI agents because it outsources Lightning complexity.

- Using a personal mint for an agent provides a potential 'undo button' if the agent loses its wallet database.

The model creates a new use case at the intersection of AI and Bitcoin. Justin argued that providing an autonomous AI agent with a full Lightning wallet seed is reckless. Fedimint’s eCash offers a safer alternative. Because a human-controlled federation operates the mint, the user retains a final override - a custodial sandbox with an 'undo button' if the agent malfunctions.

This shift toward agent-friendly tools coincides with a broader prediction that traditional app interfaces are dying. On Ungovernable Misfits, Vik Sharma described controlling a Monero command-line wallet through an AI via Telegram. He stated that if you can tell an AI what you want, you don't need a button to click. This forces wallet developers to innovate or become obsolete.

Meanwhile, the push for new custody models exists alongside persistent external threats. Sources from Bankless and Bitcoin And debated the risk of quantum computing, with some framing it as an existential technical threat and others dismissing it as marketing FUD for new chains. The consensus across shows is that Bitcoin’s real challenge is social coordination, not just code.

Fedimint’s mobile evolution represents a pragmatic step. It separates the governance of funds from the technical management of Lightning liquidity. This allows communities to custody assets while outsourcing complex channel management to specialized gateways. The result is a model that makes self-custody accessible without requiring every user to be an expert.

CD198: JUSTIN - FEDIMINT UPDATE • Apr 7

  • Justin says Fedimint's eCash app is positioned as a reference client and now includes a Nostr-based contact system, allowing users to input any Nostr public key to populate payment contacts without logging in.
  • The eCash app uses Nostr for a non-custodial recovery mechanism. It encrypts and stores federation invite codes on relays, derivable solely from the user's seed phrase.
  • Fedimint now offers Start9 and Umbrel packages for easy guardian deployment. The setup involves a ceremony where guardians exchange codes, now facilitated by QR codes for in-person setup.
  • Fedimint's Lightning Gateway is a separate entity that facilitates payments. Users trust it for uptime and liquidity, not custody, as funds remain secured by the federation's multisig.
  • A gateway can serve multiple federations, enabling capital efficiency. If a payment occurs between two users on federations served by the same gateway, it becomes an internal ledger transfer, not a Lightning payment.
  • Justin's team released an Android app that can run a Fedimint guardian, drastically lowering the barrier to entry. It runs as a foreground service, is data/power intensive, and allows setup via QR codes.
  • The Android guardian app can use Explora (Mempool.space) by default for blockchain data but can also be configured to connect to a local Bitcoin Core node.
  • Odell notes a community in South Africa is using Fedimint as a daily driver for expenses, indicating early adoption for local community banking use cases.
  • Justin says upcoming work includes making the gateway more agent-friendly, adding new consensus modules, and implementing Bolt 12, though Bolt 12 presents a trust model challenge similar to LNURL.

Also from this episode:

Protocol (3)
  • Fedimint is a chaumian eCash system using a federation of guardians. It employs a multisig where, in a typical four-guardian deployment, three signatures are required to move funds.
  • Justin argues the primary operational risk for eCash systems like Fedimint is unintentional uptime failure, not malicious rug pulls, because running high-availability services is difficult for average operators.
  • The project uses Iroh for peer-to-peer networking, removing the previous DNS requirement. Clients and guardians communicate directly via Iroh, which supports hole punching and relayed modes.
Privacy (1)
  • Justin states running a guardian can expose your IP to users and your ISP. He recommends using a VPN like Mullvad for privacy, as integrated Tor support is still in development.
AI & Tech (1)
  • Justin sees eCash as well-suited for AI agents because it outsources Lightning complexity. Using a personal mint for an agent provides a potential 'undo button' if the agent loses its wallet database.

Bitcoin Has 3 Years to Survive | Nic Carter on Bitcoin’s Quantum Vulnerability • Apr 6

  • Transitioning Bitcoin to post-quantum cryptography is complex, requiring consensus on a signature scheme, a coordinated migration of all addresses, and a decision on dormant coins.
  • The Google paper estimates 6.9 million Bitcoin are vulnerable to long-range quantum attacks, with 2.3 million considered permanently unmovable Satoshi or lost coins.
  • Nic Carter predicts Bitcoin's largest custodians and exchanges will eventually demand a fork where the unmovable Satoshi coins are burned, establishing that as the canonical BTC.
  • Carter's preferred solution uses salvage law, where a trusted entity recovers vulnerable coins and holds them in trust for their original owners, with a finder's fee, rather than protocol-level burning.

Also from this episode:

BTC Markets (2)
  • Bitcoin's governance is spectacularly unsuited to the quantum threat, which requires total mobilization for core infrastructural change under an uncertain timeline.
  • The Google and Oratomic papers published improved resource estimates for breaking Bitcoin's ECDSA cryptography, indicating the threat is closer than previously thought. The hardware does not yet exist.
Protocol (3)
  • A short-range 'on-spend' attack could intercept a Bitcoin transaction in as little as nine minutes using the improved algorithms, forcing the entire network to be post-quantum before the computer is built.
  • Post-quantum signature schemes are much larger than current ones, requiring a likely uncontroversial block size increase to accommodate the 10x to 1000x increase in transaction data.
  • Ethereum is seen as more proactive on the quantum threat, having a published roadmap and an advantage as it has not hyper-optimized around small signatures like some high-performance chains.
AI & Tech (1)
  • The authors of the Google paper suggest a fast takeoff model for quantum computing, where significant prior notice before a cryptographically relevant quantum computer exists is unlikely.
Business (1)
  • Google has accelerated its internal post-quantum transition timeline to 2029, while the U.S. government targets 2030-2035 for critical functions.

A Prescription for Privacy | The Confab 30: Vik Sharɱa • Apr 3

  • Vik Sharma sees stablecoins as a critical on-ramp for people in countries with failing local currencies to access global markets.
  • Sharma believes access to stablecoins eventually leads people in underserved markets to explore Bitcoin, Monero, and other cryptocurrencies.
  • The decentralized nature of crypto ensures people will find underground ways to access it even if governments try to ban or regulate it, according to Sharma.
  • Sharma started Cake Wallet after realizing there was no open source Monero wallet for iPhone and believing others would want the same tool.
  • The initial Cake Wallet team had no prior crypto experience and was given the freedom to study and learn before building.
  • The first version of Cake Wallet was Monero-only for about a year and a half after launch.
  • Sharma's Coinbase account was closed immediately after he sent Bitcoin directly from it to the AlphaBay darknet market to buy antibiotics.
  • Sharma observes a significant increase in interest in transactional privacy and tools like Monero today compared to four or five years ago.
  • Sharma successfully connected the Monero CLI to OpenAI's ChatGPT via Telegram, enabling voice-controlled balance checks and transactions.
  • Vik Sharma believes we live in a multi-coin world and that it is okay to have different tools for different use cases.

Also from this episode:

Payments (1)
  • Vik Sharma argues that using Bitcoin as a currency is what gives it value, citing the famous pizza purchase as a monumental milestone.
Banking (2)
  • Sharma's interest in Bitcoin was sparked by the 2008 financial crisis and the perception that government bailouts devalued people's money.
  • Sharma's experience with international wire transfers in the steel business made him acutely aware of the permissioned and cumbersome nature of traditional banking.
Privacy (2)
  • That Coinbase closure in 2016 or 2017 led Vik Sharma down the rabbit hole of chain analysis and Monero's privacy features.
  • Sharma built a privacy-focused email client disguised as a calculator app for iPhone before ever getting into cryptocurrency.
AI & Tech (2)
  • Sharma thinks AI can profile individuals with extreme accuracy based on online behavior, predicting things like voting patterns.
  • A popular NFT exchange cut its staff from 300 to 50 people by mandating that all code must be written by AI, according to Sharma.
Philosophy (1)
  • Sharma tweeted years ago that Bitcoin maximalists dislike Monero not because they don't understand Monero, but because they don't understand Bitcoin.
