-======================== +SmartPiggies + += -Alethio is a comprehensive suite of blockchain exploration and analytics products for the Ethereum network. We're on a mission of making Ethereum more transparent and accessible to everybody. +An open source standard for a free peer-to-peer global derivatives market. +- -We've recently launched our API as a direct way for developers to get real-time access to synthesised, indexed on-chain data in a robust and reliable way. We're looking to support and accelerate the growth of a new wave of Ethereum-powered tools, products and services and we need your help with building awesome, useful products for the Ethereum community by making use of the Alethio API to handle enriched, aggregated on-chain data in ways that haven't been possible before. +SmartPiggies are non-fungible digital contracts that provide their owners with protection against undesirable changes in the price of any asset, product, or service. They also have a native self-auctioning mechanism that allows them to globally market themselves, eliminating the need for exchanges. -We are strong believers in open source and decentralization - so we've also released our open-source suite, comprised of the Ethereum Lite Explorer and the EthStats network monitor - two powerful tools for monitoring the activity of any Ethereum-like (private/dev or public) network.

Today, with the guarantees provided by the Ethereum network and recent innovations provided by the global community, it is now possible to create robust programmable digital assets with linked to the real world, yet have no dependencies on centralized authorities or intermediaries. -Happy hacking! +SmartPiggies are an example of simple, useful, globally accessible, peer-to-peer financial agreements that can exist on the Ethereum network today. + +For more information on the project and to read the pinkpaper please visit the [website](https://smartpiggies.com). + +## Work done during the hackathon + +For the Ethereal Hackathon we implemented the Aleth.io APIs in a React dapp to build out a token explorer for SmartPiggies. Our explorer, which we named Amerigo, constructs a React UI, using Aleth.io and Drizzle, that allows users to explore SmartPiggies non-fungible tokens. Amerigo retrieves the event data emitted from the SmartPiggies contract and displays this token data in a helpful format so users can view the current real-time global market for SmartPiggies NFTs. + +SmartPiggies tokens hold many parameters as well as auction information. The explorer is a critical tool for token introspection and provides market making opportunities for users. + +To provide users this information we use the the Aleth.io API endpoint, + +`https://api.goerli.aleth.io/v1/contracts/{contract}/logEntries` + +to fetch all event information from the SmartPiggies contract. + +We filter for creation events and then call, + +`https://api.aleth.io/v1/log-entries/{id}/transaction` + +to fetch the transaction associated with the creation of a new token. + + +We filter this transaction information to extract a contract address for an oracle resolver that was included as an argument to create the token. We make a call with this address to, + +`https://api.goerli.aleth.io/v1/contracts/{address}` + +to fetch the oracle resolver parameters supplied during its creation. From this we get information about the associated oracle which will be called during the settlement process. + +From the oracle parameters we save the underlying and the data source, and api the oracle will use to return the price. From the other calls we save the token id, strike price, and expiry information for each NFT. We also make an additional filter for auction information that is returned with the first call for `logEntries.` + +The dapp displays this information in a component that will provide full token introspection from a clickable dropdown as well as filter options to view only tokens on auction. If the token is on auction, meaning it can be purchased, the dropdown will contain a button for purchase. + +Our goal is to continue to build out this design to offer a full feature explorer for the SmartPiggies platform which will include full market introspection, as well as the ability to purchase directly within the explorer. + +## A specific industry, user, and use case for which you are solving + +SmartPiggies is a decentralized financial product for use by small business and individuals to hedge against price movements of any asset, product, or service for which a price can be retrieved, + +SmartPiggies are effectively a price insurance product. SmartPiggies are effective for a specified period of time, provide a specified maximum amount of coverage, and pay out based on specified conditions as would any typical insurance product. An insurance issuer receives a premium in exchange providing this insurance. + +We envision that the primary purchasers of SmartPiggy contracts will be small businesses that are underserved by the global financial system and are exposed to fluctuations in prices for goods, services, and exchange rates that that are inherent to their business activities. + +## Unique insights about the industry gathered through primary or secondary research + +The DeFi industry has spawned a number of lending and derivatives products, as well as novel enabling technologies such as stable tokens intended to peg to the value of “real-world” currencies. However, as far as the team is aware, no product offering price insurance in the manner of SmartPiggies yet exists. The industry in general offers users the potential to earn “passive income” on various lending products, but this often entails turning over control of one’s cryptocurrency to a lending platform with the expectation that one will be compensated in interest, and eventually, the return of one’s principal. With SmartPiggies, underwriters have the potential to earn a “passive” income stream through insurance premia, without turning their funds over to a third party -- all funds remain locked in the SmartPiggies contract with no capability for those funds to be moved by a privileged account. The only factors affecting the ultimate distribution of funds are the parameters of the smart contract which both the underwriter and purchaser agreed to at the time the option was sold. + +Other derivatives in the DeFi industry space do not appear to currently offer the flexibility of SmartPiggies, or the ability to easily hedge risks in non-cryptocurrency financial instruments through the use of stable token payouts. The team believes that this capability opens up many more use cases for decentralized derivatives than the industry has thus far offered to customers. + +## Proof that the market you've identified is primed to be disrupted in the next 6-12 months + +As we have seen significant cryptocurrency adoption in countries where the need is great, we also believe that small businesses and individuals around the world that suffer through fluctuations in price will immediately grasp that SmartPiggies may be useful to them. + +In our view we are not disrupting an existing market. We are creating an ecosystem that generates a financial service that has never before been available to the vast majority of humanity due to scale and and availability issues inherent to the existing global financial and legal system. + +## Proof that blockchain adds significant value to this solution over centralized alternatives + +The current centralized market for bespoke derivatives is largely closed to non-institutional investors, given the relationship nature of the business, and the cost of the infrastructure required for large institutions to manage their derivatives desks and legal teams. However, price insurance is not a tool which only has value to institutional investors -- many small business owners, for example, could likely utilize bespoke options to protect their enterprises from price shocks if they had access to them. With SmartPiggies, such users can realize the value of such insurance, and underwriters wishing to earn income from premia may issue SmartPiggies without being a large financial institution. Thanks to the programmability and security guarantees of the blockchain, the purchaser of a SmartPiggies option does not need to worry about the counterparty risk of any specific underwriter -- all collateral associated with the option is secured on-chain out of the control of either counterparty before the option is even sold. This increase in market access for both buyers and sellers of price insurance marks a definite improvement over the status quo in current centralized markets for bespoke options. + +## Project Rollout + +Our rollout plans are flexible at the moment. + +For now we are focused on on constructing the MVP contracts and minimal UI components. + +If we manage to raise funding at some point in the future we can consider outreach and education efforts, a more sophisticated UI, publishing research and use cases, providing a trusted exchange service, and providing liquidity to the market. +As of now we are unfunded and as such our scope is limited to working on an MVP in our spare time. + +## Team +[Michael Arief](https://www.linkedin.com/in/mikearief/) + +[Toby Algya](https://www.linkedin.com/in/toby-algya-58997712/) + +[Alex Lee](https://www.linkedin.com/in/ahlee328/) + +## Tech stack + +- Ethereum + +- Aleth.io + +- Goerli Testnet + +- Metamask + +- Solidity + +- OpenZeppelin + +- Truffle + +- Drizzle + +- Ganache + +- ReactJS + +- NodeJS + +- Chainlink diff --git a/app/.gitignore b/app/.gitignore new file mode 100644 index 0000000..4d29575 --- /dev/null +++ b/app/.gitignore @@ -0,0 +1,23 @@ +# See https://help.github.com/articles/ignoring-files/ for more about ignoring files. + +# dependencies +/node_modules +/.pnp +.pnp.js + +# testing +/coverage + +# production +/build + +# misc +.DS_Store +.env.local +.env.development.local +.env.test.local +.env.production.local + +npm-debug.log* +yarn-debug.log* +yarn-error.log* diff --git a/app/README.md b/app/README.md new file mode 100644 index 0000000..9d9614c --- /dev/null +++ b/app/README.md @@ -0,0 +1,68 @@ +This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app). + +## Available Scripts + +In the project directory, you can run: + +### `npm start` + +Runs the app in the development mode.

For 0.4.24 support, use version 2.0 of OpenZeppelin. + * `WhitelistCrowdsale`: a crowdsale where only whitelisted accounts (`WhitelistedRole`) can purchase tokens. Adding or removing accounts from the whitelist is done by whitelist admins (`WhitelistAdminRole`). Similar to the pre-2.0 `WhitelistedCrowdsale`. ([#1525](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1525), [#1589](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1589)) + * `RefundablePostDeliveryCrowdsale`: replacement for `RefundableCrowdsale` (deprecated, see below) where tokens are only granted once the crowdsale ends (if it meets its goal). ([#1543](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1543)) + * `PausableCrowdsale`: allows for pausers (`PauserRole`) to pause token purchases. Other crowdsale operations (e.g. withdrawals and refunds, if applicable) are not affected. ([#832](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/832)) + * `ERC20`: `transferFrom` and `_burnFrom ` now emit `Approval` events, to represent the token's state comprehensively through events. ([#1524](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1524)) + * `ERC721`: added `_burn(uint256 tokenId)`, replacing the similar deprecated function (see below). ([#1550](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1550)) + * `ERC721`: added `_tokensOfOwner(address owner)`, allowing to internally retrieve the array of an account's owned tokens. ([#1522](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1522)) + * Crowdsales: all constructors are now `public`, meaning it is not necessary to extend these contracts in order to deploy them. The exception is `FinalizableCrowdsale`, since it is meaningless unless extended. ([#1564](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1564)) + * `SignedSafeMath`: added overflow-safe operations for signed integers (`int256`). ([#1559](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1559), [#1588](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1588)) + +### Improvements: + * The compiler version required by `Array` was behind the rest of the libray so it was updated to `v0.4.24`. ([#1553](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1553)) + * Now conforming to a 4-space indentation code style. ([1508](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1508)) + * `ERC20`: more gas efficient due to removed redundant `require`s. ([#1409](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1409)) + * `ERC721`: fixed a bug that prevented internal data structures from being properly cleaned, missing potential gas refunds. ([#1539](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1539) and [#1549](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1549)) + * `ERC721`: general gas savings on `transferFrom`, `_mint` and `_burn`, due to redudant `require`s and `SSTORE`s. ([#1549](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1549)) + +### Bugfixes: + +### Breaking changes: + +### Deprecations: + * `ERC721._burn(address owner, uint256 tokenId)`: due to the `owner` parameter being unnecessary. ([#1550](https://github.com/OpenZeppelin/openzeppelin-solidity/pull/1550)) + * `RefundableCrowdsale`: due to trading abuse potential on crowdsales that miss their goal.

token holder has to opt-in to the migration.\nTo opt-in, users must approve for this contract the number of tokens they\nwant to migrate. Once the allowance is set up, anyone can trigger the\nmigration to the new token contract. In this way, token holders \"turn in\"\ntheir old balance and will be minted an equal amount in the new token.\nThe new token contract must be mintable. For the precise interface refer to\nOpenZeppelin's ERC20Mintable, but the only functions that are needed are\n`isMinter(address)` and `mint(address, amount)`. The migrator will check\nthat it is a minter for the token.\nThe balance from the legacy token will be transfered to the migrator, as it\nis migrated, and remain there forever.\nAlthough this contract can be used in many different scenarios, the main\nmotivation was to provide a way to migrate ERC20 tokens into an upgradeable\nversion of it using ZeppelinOS. To read more about how this can be done\nusing this implementation, please follow the official documentation site of\nZeppelinOS: https://docs.zeppelinos.org/docs/erc20_onboarding.html\nExample of usage:\n```\nconst migrator = await ERC20Migrator.new(legacyToken.address);\nawait newToken.addMinter(migrator.address);\nawait migrator.beginMigration(newToken.address);\n```", + "fullyImplemented":

"devdoc": { + "details": "This contract can be used to migrate an ERC20 token from one contract to another, where each token holder has to opt-in to the migration. To opt-in, users must approve for this contract the number of tokens they want to migrate. Once the allowance is set up, anyone can trigger the migration to the new token contract. In this way, token holders \"turn in\" their old balance and will be minted an equal amount in the new token. The new token contract must be mintable. For the precise interface refer to OpenZeppelin's ERC20Mintable, but the only functions that are needed are `isMinter(address)` and `mint(address, amount)`. The migrator will check that it is a minter for the token. The balance from the legacy token will be transfered to the migrator, as it is migrated, and remain there forever. Although this contract can be used in many different scenarios, the main motivation was to provide a way to migrate ERC20 tokens into an upgradeable version of it using ZeppelinOS. To read more about how this can be done using this implementation, please follow the official documentation site of ZeppelinOS: https://docs.zeppelinos.org/docs/erc20_onboarding.html Example of usage: ``` const migrator = await ERC20Migrator.new(legacyToken.address); await newToken.addMinter(migrator.address); await migrator.beginMigration(newToken.address); ```", + "methods": { + "beginMigration(address)": { + "details": "Begins the migration by setting which is the new token that will be minted.

This technique is useful for whitelists and airdrops; instead of putting all valid addresses on-chain, simply sign a grant of the form keccak256(abi.encodePacked(`:contractAddress` + `:granteeAddress`)) using a valid signer address. Then restrict access to your crowdsale/whitelist/airdrop using the `onlyValidSignature` modifier (or implement your own using _isValidSignature). In addition to `onlyValidSignature`, `onlyValidSignatureAndMethod` and `onlyValidSignatureAndData` can be used to restrict access to only a given method or a given method with given parameters respectively.
