Decentralized digital asset exchange protocol running on Ethereum. Buy and sell everything from virtual kittens to smart contracts with no counterparty risk.
@CryptoGoblin Wyvern has a bit of a different fee system (although using WYV is an option), read more at https://t.co/y97IFefOhC. To our knowledge, all the exchanges using the Wyvern Protocol are charging zero fees at the moment.
Congrats to OpenSea on launching their Wyvern integration, allowing users to place bids for any nonfungible token (without even paying gas), now live on mainnet! https://t.co/c2zCozFpwC
Just launched a major upgrade to our marketplace. Introducing "Make an Offer" - now you can bid on any crypto collectible without paying gas, regardless of whether it's on sale! https://t.co/Ob3EfJiqqJ
Wyvern abstracts over Ethereum transactions themselves, so it supports *any* asset you can represent on Ethereum - ERC20, ERC721, ERC-not-yet-written - you don't even need to deploy an additional contract to support a new asset type! https://t.co/vilHa7NnRa
@mattdlockyer This is new functionality that doesn't exist elsewhere afaik - not on Rarebits and 0x doesn't easily support it yet for ERC721. The Opensea team used the Wyvern protocol to support it
@mokens_io You can encode it directly yourself using web3 libraries and the ABI of your asset contract. We also provide a library of standard asset schemas - https://t.co/0I2NcHotWA - likely one of these is close to what you're using and could be adapted.
@mokens_io This means that any asset transferrable with an Ethereum transaction can be bought, sold, or auctioned using Wyvern - just create an order with the transfer call bytecode specific to that asset. Wyvern automatically supports all existing and future standards.
Transactions are the wrong UX abstraction, users want to sign sets of authorized state transitions - subscription payment once a month, limited spends from a phone, allowance for a family member, etc - this may be possible on @ethereum, (rough) thoughts: https://t.co/MXyGDbwx4r
@js_horne Requires a bit of extra setup since breeding is multi-stage, but it should be possible - the second use case you mention, paying for linking an artwork, can already be done without writing any new contracts.
Fantastic article by @js_horne on how open protocols and non-fungible tokens will reshape the flow of value in the digital world https://t.co/eTcKAgcXXn
@js_horne Yes - Wyvern abstracts over Ethereum transaction bytecode, so you can create buy or sell orders for any on-chain state transition. For example, you could create an order to bid for anyone who could breed with your CryptoKitty and sire offspring with some particular quality.
@foamspace@js_horne And using Wyvern anyone could place an order to buy any such NFT - even if it doesn't yet exist - provably created within a specified radius of the location!
