Services Provided by OpenSea as of 2023. Wyvern can be deployed on any EVM-based blockchain, allowing developers to power their asset exchange. Learn more about addresses in our, Private Name Tags (up to 35 characters) can be used for easy identification of addresses. I just uploaded an update that should support Wyvern 2.3. The token approval prompt that appears in MetaMask will look something like this: Let's dissect this. Available as a browser extension and as a mobile app, MetaMask equips you with a key vault, secure login, token wallet, and token exchangeeverything you need to manage your digital assets. First, select the crypto pair you'd like to swap. To facilitate ease-of-use, Wyvern supports special-case Ether to the maximum extent possible: the matcher of an order may elect to pass value along with the match transaction, which is then transferred to the counterparty and passed as a parameter to the predicate function (which can assert e.g. The static callback receives all parameters - the countercall target, the countercall type (CALL or DELEGATECALL), and the countercall data - and must validate that the call is one which the maker is willing to accept in return for their own (e.g. The Address 0x358F8833130bB2aAadc334D904F64f1bF8D1ac9e page allows users to view transactions, balances, token holdings and transfers of ERC-20, ERC-721 and ERC-1155 . Contract Internal Transactions as a result of contract execution on the Ethereum blockchain. Finally, an order can be constructed on the fly (likely to match an existing previously signed or approved order) and authorized at match time simply by sending the match transaction from the order's maker address. 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). In some cases this may be more efficient, but it is trickier to reason through and could lead to unintentional consequences if the state changed for other reasons (for example, if the asset you were trying to buy were gifted to you) - so this is recommended for special cases only, such as placing a bug bounty on a contract if an invariant is violated. MetaMask tries to make sending and receiving ERC-20 tokens simple & safe. This is costless - any number of orders can be signed, stored, indexed, and perhaps listed on a website or automated orderbook. Metadata contains order listing time, order expiration time, counterorder listing time, Ether passed in the call (if any), current order fill value, and the matching address. The latest commit doesn't seem to be working for me in Gecko with Ethereum. The text was updated successfully, but these errors were encountered: I've to work on this if it causes a fail of the contract signature. English . The current fill of an order can also be manually set by the maker of the order with a transaction (this also allows for order cancellation). EDIT - tested again and confirmed - it still doesn't work for me. . Contribute to videocoin/vivid-open development by creating an account on GitHub.
