🌐Dexter v1 Deep Dive — Curating the best AMMs-Built On Persistence🌐
January 30, 2023

Dexter has traveled far and wide and knows a lot about AMMs, and now brings all the wisdom into building his AMM base on Persistence Core. Let’s dive into the blueprints!

AMMs have revolutionized markets by allowing users to trade anytime without needing a counterparty. Pioneered by Uniswap in 2018, they serve as an essential building block in DeFi.

Dexter v1 will bring tried and tested AMM mechanisms to the Interchain, inspired by the best innovations in all of DeFi, and will support assets from other IBC-enabled chains.

At launch, Dexter would feature the following types of AMMs -

Stableswap — Inspired by Curve

A stableswap is an automated market maker (AMM) optimized for similarly priced tokens and provides minimum slippage and efficient liquidity provision.

Constant product AMMs are useful for price discovery since moving on the curve in either direction will affect the price of each asset. However, this price curve makes it difficult to swap closely pegged assets, which should theoretically trade without affecting each other’s price.

The constant sum pool (X + Y = K) has no slippage but can run out of liquidity when the pool is imbalanced on one side. The constant product pool (X*Y=K) has slippage but can always maintain liquidity since the price of an asset increases with the demand.

Stableswap combines the constant product and constant sum functions to achieve minimum slippage and provide a balanced pool. This function acts as a constant sum when the pool is balanced, providing low slippage trades, and shifts towards a constant product as the pool becomes more imbalanced to ensure the pool never runs out of liquidity.

Stableswap on Dexter will support liquid-staked assets, which are highly correlated with the underlying staked assets. Liquidity for these assets would boost their utility in DeFi.The stableswap will facilitate low slippage trades for assets like stkATOM and stATOM with base assets like ATOM. This will allow stakers to instantly redeem their staked assets by swapping their liquid-staked assets into the base asset.

Bridges like Axelar and Gravity are pouring massive amounts of stablecoin liquidity to Cosmos from Ethereum and other ecosystems. Moreover, with the rise of native stablecoins like IST and SILK, along with USDC coming up natively on a consumer chain with Interchain Security, stableswap would serve as a vital part of the Cosmos DeFi ecosystem.

By supporting these assets, Dexter aims to become the liquidity hub for yield-generating assets and stablecoins in the Cosmos ecosystem.

Ā 

Stable -3/5 Pools

Dexter will also support stableswap pools with more than two tokens, like Curve’s 3pool, which provided enormous liquidity for three top stablecoins in DeFi — USDT, USDC, and DAI. Stable 3/5 pools on Dexter would support 3 to 5 highly correlated assets.

The liquid-staking landscape in Cosmos is diverse, with multiple players like pSTAKE, Quicksilver, and Stride. Stable — 3/5 pools on Dexter would support liquid-staked assets from all these zones and facilitate low slippage trading between these assets.

For example — stkATOM/stATOM/qATOM

Ā 

Weighted Pools — Inspired by Balancer

Dexter will support a custom weighted pool AMM mechanism inspired by Balancer, which allows users to create a custom pool of assets and choose their weightage for each asset, such as pools with 60/40 or 60/20/20 weightage, in contrast to the constant product AMM mechanism, which only offers 50/50 weightage. This pool type supports up to 8 assets in a single pool.

Pools that weigh one token heavily offer a significant improvement in terms of impermanent loss to the user compared to 50–50 pools. Impermanent loss is significantly less for highly imbalanced pools like 95/5, but this leads to high slippage due to low liquidity for one of the assets. Weighted pools allow users to customize their exposure to assets and maintain a balance in impermanent loss.

Weighted pools with more than two assets would allow traders to trade multiple combinations of assets on a single pool, saving them the swap fees to be paid on multiple swaps.

Ā 

Fees on Dexter

There are two primary types of fees traders pay on Dexter —

  • On-Chain Transaction/Gas Fees
  • Swap Fees

Transaction fees are paid by any user to post a transaction on the chain. The transaction fee is distributed to XPRT stakers on the network as block rewards.

Swap fees are charged to all traders performing swaps in any of the pools available on Dexter. Swap fees are calculated as a percentage of the swap amount specific to each pool. Swap fees are charged on the input asset of a swap (So if a user swaps ATOM for XPRT, they pay the swap fee in the form of ATOM). The default fee is set to 0.3%, which is a configurable parameter. The swap fee will be distributed between liquidity providers and protocol treasury.

Ā 

Conclusion

Dexter v1 features tried and tested mechanisms, including weighted pools, and stable 3/5 pools, to facilitate efficient trading for yield-generating assets. Dexter would continue to explore more innovative AMM mechanisms and keep building upon its base in the future.

The Great Onboarding: US Government Anchors Global Economy into Web3 via Pyth Network

For years, the crypto world speculated that the next major cycle would be driven by institutional adoption, with Wall Street finally legitimizing Bitcoin through vehicles like ETFs. While that prediction has indeed materialized, a recent development signifies a far more profound integration of Web3 into the global economic fabric, moving beyond mere financial products to the very infrastructure of data itself. The U.S. government has taken a monumental step, cementing Web3's role as a foundational layer for modern data distribution. This door, once opened, is poised to remain so indefinitely.

The U.S. Department of Commerce has officially partnered with leading blockchain oracle providers, Pyth Network and Chainlink, to distribute critical official economic data directly on-chain. This initiative marks a historic shift, bringing immutable, transparent, and auditable data from the federal government itself onto decentralized networks. This is not just a technological upgrade; it's a strategic move to enhance data accuracy, transparency, and accessibility for a global audience.

Specifically, Pyth Network has been selected to publish Gross Domestic Product (GDP) data, starting with quarterly releases going back five years, with plans to expand to a broader range of economic datasets. Chainlink, the other key partner, will provide data feeds from the Bureau of Economic Analysis (BEA), including Real Gross Domestic Product (GDP) and the Personal Consumption Expenditures (PCE) Price Index. This crucial economic information will be made available across a multitude of blockchain networks, including major ecosystems like Ethereum, Avalanche, Base, Bitcoin, Solana, Tron, Stellar, Arbitrum One, Polygon PoS, and Optimism.

This development is closer to science fiction than traditional finance. The same oracle network, Pyth, that secures data for over 350 decentralized applications (dApps) across more than 50 blockchains, processing over $2.5 trillion in total trading volume through its oracles, is now the system of record for the United States' core economic indicators. Pyth's extensive infrastructure, spanning over 107 blockchains and supporting more than 600 applications, positions it as a trusted source for on-chain data. This is not about speculative assets; it's about leveraging proven, robust technology for critical public services.

The significance of this collaboration cannot be overstated. By bringing official statistics on-chain, the U.S. government is embracing cryptographic verifiability and immutable publication, setting a new precedent for how governments interact with decentralized technology. This initiative aligns with broader transparency goals and is supported by Secretary of Commerce Howard Lutnick, positioning the U.S. as a world leader in finance and blockchain innovation. The decision by a federal entity to trust decentralized oracles with sensitive economic data underscores the growing institutional confidence in these networks.

This is the cycle of the great onboarding. The distinction between "Web2" and "Web3" is rapidly becoming obsolete. When government data, institutional flows, and grassroots builders all operate on the same decentralized rails, we are simply talking about the internet—a new iteration, yes, but the internet nonetheless: an immutable internet where data is not only published but also verified and distributed in real-time.

Pyth Network stands as tangible proof that this technology serves a vital purpose. It demonstrates that the industry has moved beyond abstract "crypto tech" to offering solutions that address real-world needs and are now actively sought after and understood by traditional entities. Most importantly, it proves that Web3 is no longer seeking permission; it has received the highest validation a system can receive—the trust of governments and markets alike.

This is not merely a fleeting trend; it's a crowning moment in global adoption. The U.S. government has just validated what many in the Web3 space have been building towards for years: that Web3 is not a sideshow, but a foundational layer for the future. The current cycle will be remembered as the moment the world definitively crossed this threshold, marking the last great opportunity to truly say, "we were early."

US Dept of Commerce to publish GDP data on blockchain

On Tuesday during a televised White House cabinet meeting, Commerce Secretary Howard Lutnick announced the intention to publish GDP statistics on blockchains. Today Chainlink and Pyth said they were selected as the decentralized oracles to distribute the data.

Lutnick said, ā€œThe Department of Commerce is going to start issuing its statistics on the blockchain because you are the crypto President. And we are going to put out GDP on the blockchain, so people can use the blockchain for data distribution. And then we’re going to make that available to the entire government. So, all of you can do it. We’re just ironing out all the details.ā€

The data includes Real GDP and the PCE Price Index,Ā which reflects changes in the prices of domestic consumer goods and services. The statistics are released monthly and quarterly. The biggest initial use will likely be by on-chain prediction markets. But as more data comes online, such as broader inflation data or interest rates from the Federal Reserve, it could be used to automate various financial instruments. Apart from using the data in smart contracts, sources of tamperproof data šŸ‘‰will become increasingly important for generative AI.

While it would be possible to procure the data from third parties, it is always ideal to get it from the source to ensure its accuracy. Getting data directly from government sources makes it tamperproof, provided the original data feed has not been manipulated before it reaches the oracle.
