Valkyrie is a decentralized NFT marketplace protocol for the Vechain ecosystem that went live in March of 2019 with the CometVerse marketplace as the flagship relayer, and several other marketplaces on the way.

Valkyrie 1.0

Version 1.0 of Valkyrie enables English auctions and instant purchase prices for VIP181 tokens. Valkyrie utilizes a hybrid relayer model where as much of the process is moved off-chain as possible without sacrificing security. Relayers facilitate the auction process while selectively displaying information about ongoing auctions (e.g. whether the auction is “open” or “closed” is up to the relayer to handle).

Protocol Overview

Valkyrie’s hybrid relayer model packages bids and instant purchase offers as off-chain VIP190 signed messages. Only bid/offer cancellation and auction settlement require transactions.

In this model, the relayer collects and stores orders from bidders and sellers, and displays them given its own choice in logic. The Valkyrie protocol provides the flexibility to design the auctions per the relayer’s goals. This allows for a more efficient, usable platform while maintaining the security benefits of on-chain asset transfers.

Build on Valkyrie

Valkyrie is an open protocol that anyone can use. We’ve put together several pieces of documentation to help developers get started building their marketplaces on Vechain.
