Yield Basis: Disrupting Defi & Bitcoin Yield

Épisode 623

mercredi 5 novembre 2025 • Durée 01:00:05

Brian Fabian Crain and Michael Egorov, Curve Finance founder, discuss Curve's origins: solving inefficient DAI/USDC swaps after MakerDAO borrows by creating a DeFi AMM for stablecoins and LSTs.

It hit 1M TVL with a bonding curve concentrating liquidity at 1:1, more effective for pegged assets than Uniswap. Features grew to include BTC wrappers, stETH pairs, and crvUSD (a CDP stablecoin with reversible liquidations & a peg-keeper).

Governance uses veCRV: Locking CRV grants voting power proportional to lock duration, a mechanism now refined in Yield Basis.

Yield Basis solves impermanent loss in volatile pools (e.g., BTC/crvUSD). Users deposit BTC; the protocol borrows crvUSD, pairs it at 2x leverage (50% debt/equity), and uses LP tokens as collateral. This gives 1:1 asset tracking, while fees accrue from auto-rebalancing arbitrage.

Simulations show 20%+ APY (may decline as BTC volatility drops) under a $50B TVL cap. It complements Curve by directing veCRV incentives to crvUSD pools, enhancing liquidity, fees, and DAO revenues. Key considerations: manual migrations, deterring forks, and dev support to scale.

Lamina1: Building The Future of The Creator Economy

Épisode 622

mercredi 29 octobre 2025 • Durée 59:47

Sci-fi titan Neal Stephenson, whose Snow Crash coined the term 'metaverse' and Cryptonomicon, which foreshadowed crypto in 1999, joins Friederike to discuss his "hard sci-fi" method: building immersive, consistent worlds, not prophecy. He's now co-founder of Lamina1, aiming to restore Web1's ethos and give creators IP sovereignty with direct micropayments, breaking free from Web2's "walled gardens."

Neal unpacks Web3's promise like "intent-casting" flipping ad models while citing its critical traps: abysmal UX, criminal stigma, and the "soul-crushing" risk of just upgrading incumbent systems.

Spotlighting Lamina 1's game "Artifact," he argues Web3's true success will be measured when the technology becomes invisible and safe, proving its value by restoring sovereignty to its users and creators, rather than through speculative hype.

Topics discussed in this episode:

(00:00) Introduction to Decentralization and Blockchain
(01:20) The Role of Storytelling in Technology Prediction
(03:48) The Balance of Optimism and Pessimism in Fiction
(06:27) Web3: Promises and Pitfalls
(08:36) The Evolution of the Web: From Decentralization to Centralization
(13:37) Metrics for a Decentralized Web
(15:55) Lamina One: A New Vision for the Metaverse
(23:44) Creating a Financial Layer for the Creator Economy
(25:08) Legal Implications of Smart Contracts
(27:38) The Strength of Smart Contracts
(31:04) Decentralization vs. Centralization in the Creator Economy
(36:21) The Decline of Centralized Platforms
(41:23) Financialization and the Creative Economy

Rand Hindi: Zama - Fully Homomorphic Encryption in Blockchain Applications & Privacy

Épisode 523

vendredi 24 novembre 2023 • Durée 59:21

Homo- (Greek prefix meaning ‘same’); -morphic (Greek suffix meaning ‘having a specific shape/form’)
Intuitively, one could deduct that homomorphic encryption indicates that the initial data and the encrypted result (cipher) could share the same form. Based on this property, it can be inferred that computation can be performed on the encrypted data, without prior decryption. By decrypting the result, you get the same output as the computation performed on the unencrypted data. While homomorphic encryption can be either additive or multiplicative, fully homomorphic encryption supports both types of operations. Unlike ZKPs, which are proofs of computational integrity, fully homomorphic encryption allows for encrypted data computation, without revealing additional information about the original data. This could provide the missing link for ensuring private transactions on blockchains’ public ledgers.

We were joined by Rand Hindi, CEO of Zama, to discuss fully homomorphic encryption solutions, how they differ from ZKPs & MPC, and how they can be leveraged to ensure compliant programmable privacy.

Topics covered in this episode:

Rand’s background and his interest in privacy

Charles d'Haussy: dYdX V4 - Decentralised Perpetual Exchange on a Cosmos Appchain

Épisode 521

vendredi 10 novembre 2023 • Durée 01:12:39

Leading decentralised perpetual exchange, dYdX V4 recently migrated to Cosmos to build its own sovereign appchain, in order to provide its users a much better trading experience, while continuing to deliver DeFi innovations (e.g. permisionless markets). By having full control over the appchain’s parameters, the dYdX DAOs can shape the future of the protocol, starting from the very bedrock, ensuring proper distribution and incentives for the validator set. From early adopter of L2 zero knowledge proofs (STARKs), to building its own Cosmos appchain, dYdX has proven once again to be a trailblazer for new technologies.

We were joined by Charles d’Haussy, CEO of dYdX Foundation, to discuss dYdX V4’s recent migration to a Cosmos appchain and what challenges it solves in terms of: order book decentralisation, validator distribution and user experience.

Topics covered in this episode:

Nick Johnson: ENS - Multichain ENS Domains and Decentralised Identities

Épisode 520

samedi 4 novembre 2023 • Durée 01:06:11

The very nature of Ethereum addresses, expressed as random hexadecimal character strings, represents a big hurdle for mass adoption, as they are not human-readable. ENS domains were envisioned to not only solve this and provide a seamless UX, but to also be the cornerstone of on-chain identities. However, in the current multichain landscape, a plethora of decentralised naming services arose, which led to a heterogeneous domain name pool. As a result, ENS aims to expand to L2s and non-EVM chains, attempting to provide consistency, in order to further reduce user friction and limit conflicting domain names.

We were joined by Nick Johnson, founder of ENS, to discuss the current state of decentralised naming services from a multichain and L2 perspective, and how these ultimately tie into decentralised identities.

Topics covered in this episode:

Nick’s background and ENS history
The plethora of decentralised naming services
ENS use cases
Interacting with Web2 DNS
L2 compatibility for ENS via CCIP Read
ENS wrapper and subdomains
CCIP Read
Bridging ENS to non-EVM L2s

Simon Harman: Chainflip - Native cross-chain AMM

Épisode 519

vendredi 27 octobre 2023 • Durée 01:03:59

While competition fosters innovation, the proliferation of different blockchains has resulted in the fragmentation and isolation of liquidity within each ecosystem. Early attempts to address this issue primarily involved bridges and wrapped assets. Unfortunately, these solutions were often vulnerable to hacks and exploits, and the value of wrapped assets was contingent on the security of the wrapper contract, rather than the underlying asset. Cross-chain swaps of native assets hold the promise of resolving liquidity fragmentation, but numerous technological challenges must be overcome to make them as seamless as same-chain swaps.

We were joined by Simon Harman, founder of Chainflip, to discuss multi-chain liquidity fragmentation and how Chainflip’s JIT AMM (Just in Time) aims to solve this, by providing cross-chain native swaps.

Topics covered in this episode:

Simon’s background
(Legacy) Bridging vs. Threshold Signature Scheme
Chainflip’s Just in Time (JIT) AMM vs. Uniswap’s V3/X
Providing liquidity on Chainflip

Guy Young: Ethena - USDe Synthetic Dollar via Delta-Neutral Staked Ethereum Hedging

Épisode 518

vendredi 20 octobre 2023 • Durée 52:52

Stablecoins represent a safe haven against crypto’s volatility, allowing participants to remain in the market, without off-ramping to fiat. While the major stablecoins are centrally issued (e.g. USDT, USDC, BUSD), there is a pressing need for an algorithmic variant or a synthetic dollar asset. (DAI is somewhere in between since approximately 50% of its collateral is USDC). After Luna’s collapse, many jumped to point out its design flaws, yet such a concept would be crucial for crypto’s decentralisation and self-sustainability. Arthur Hayes proposed an interesting concept of NAKA synthetic dollar (NUSD), backed by Bitcoin and its inverse perpetual swap short. However, yield generation on $BTC is significantly lower than that of $ETH. A sustainable yield would help balance the cases in which funding rates would be negative (a minority in crypto).

We were joined by Guy Young, co-founder of Ethena, to discuss the stablecoin landscape and their synthetic eUSD, backed by staked ETH and its inverse perpetual swap.

Topics covered in this episode:

Guy’s background and founding Ethena
The history of stablecoins
The stablecoin trilemma and transparency
eUSD synthetic dollar mechanics
Ethena’s insurance fund and hedging
Minimising the impact of depegging
Leveraging centralised liquidity while maintaining self custody through MPC

Evgeny Yurtaev: Zerion - Web3 Wallet UX 2.0

Épisode 517

vendredi 13 octobre 2023 • Durée 57:36

One of the best known memes in crypto is: 'Not your keys, not your coins'. This usually resurfaces whenever a (custodial) centralised exchange is hacked or goes bust altogether. Although Web3 provides the infrastructure for self custody, this often shares the fate of Pandora. Self-custody requires increased security measures, from both end-users, as well as application developers. Web3 wallets are the interface between users and decentralised applications deployed on blockchains. While Metamask still maintains the largest market share, a multitude of wallets have emerged, promising additional features and a better UX.

We were joined by Evgeny Yurtaev, co-founder & CEO of Zerion, to discuss the challenges of building a Web3 wallet and how Zerion aims to improve user experience, while still maintaining security.

Topics covered in this episode:

Evgeny’s background
The motivation behind building a Web3 wallet
Zerion UX and security
Seed phrase storing
Zerion user profile
Challenges in building a new wallet app
Protecting users and potential attack vectors
Supported blockchains and (seamless) bridging
Account abstraction and MPC
