These predicates are arbitrary - any asset or any combination of assets representable on Ethereum can be exchanged with a Wyvern order - and indeed, Wyvern can instantiate all the aforementioned protocols. Project Wyvern is a decentralized digital asset exchange protocol running on Ethereum. To access the funds in an address, you must have its private key. They are always initiated in MetaMask with a call to the eth_sendTransaction method.

MetaMask provides the simplest yet most secure way to connect to blockchain-based applications. Wyvern orders instead specify predicates over state transitions: an order is a function mapping a call made by the maker, a call made by the counterparty, and order metadata to a boolean (whether or not the order will match). In practice, orderbook maintainers (relayers) will likely store additional metadata along with orders which can be used to construct possible matching calldatas.

If the maker intends to send the transaction matching the order themselves, this method may be convenient, and it can be used to save a bit of gas (since calldata verification is implied by sending the transaction). transferring a particular asset or set of assets). A contract address hosts a smart contract, which is a set of code stored on the blockchain that runs when predetermined conditions are met. Static calls are executed after the calls (the whole transaction is reverted if the static call fails), so instead of asserting properties of the calldata, you can assert that particular state has changed - e.g. Ethereum Mainnet. The contract address will be clearly indicated on its page. Copy link Owner maximedrn commented Mar 2, 2022.
