Metamascus: No transmission functionality on ERC721
As a construction programmer and deployment of decentralized applications (DAPPS) on Blockchain networks, one of the most exciting features in which users enjoy the possibility of transferring digital assets such as NFT from their wallets to others or back to wallet. This functionality is achieved by different transmission protocols that allow users to interact with external wallet, such as metamas.
However, for a forging agreement based on a token (NFT) based on ERC-721 on Blockchain such as Ethereum or Polygon, one of the most frustrating issues is unable to use a built-in functionality of metamascular tokens. In this article, we will explore the reasons behind this restriction and provide solutions to resolve.
Problem: No transmission functionality
When the contract ERC-721 NFT forged on blockchain like Ethereum or Polygon uses the function of `~ '‘ _MINTfunction provided Just examine and communicate with NFT directly in their wallet wallets. However, when trying to transfer the NFT from a contract to another address or back to the original wallet, users face the problem.
Problem: No Sending Functionality
To transmit NFT using the built-in functionality of metamask, you must communicate with the function ofeth_sendransation, which allows you to send transactions to Ethereum blockchain. Unfortunately, when trying to use this function on a contract based on ERC-721 forged on another blockchain such as Polygon or Binance Smart Chain (BSC), users meet with gray functionality in metamask.
The reason for this limit
This restriction stems from the fact that the SDK and supplements of metamas do not support ERC-721 NFTS. The reason for this is probably due to the unique nature of Ethereum Blockchain, which is designed to simultaneously launch more smart contracting platforms. In addition, Polygon and BSC have their own set of limitations and restrictions when it comes to interaction with external wallets.
Solutions
Although there may be no official solution from a metamic or blockchain ecosystem as a whole, several bypass can help you solve this problem:
- Use another wallet: Try using another wallet supporting ERC-721 NFTS, such as wallet, coinbase wallet or wallet wallet.
- Spending your own transfer function: Consider implementing the custom transfer function in a contract that communicates with the function ofeth_sendtransation
and uses external APIs to send transactions to the target blockchain.
- Use a library or frame: Explore with libraries or frames such as OpenzeppelinERC721TOKENFACTORY`, which provide installed support for ERC-721 NFTS and offer functionality of transmission.
- Contact the blockchain network operators:
Come to the Operator of the Target Blockchain Network (eg Polygon, BSC) and ask if I can implement a custom solution or provide a solution.
Conclusion
The limit to the use of the installed transmission function metamas for NFTS based on ERC-721 forged contracts on various blockchain platforms is frustrating. However, by researching bypass solutions and implementing customized solutions, you can still achieve the functionality you need to interact with the assets from the comfort of your wallet.
As developers, it is crucial to be ongoing with the latest achievements in the blockchain ecosystem and explore available libraries and frameworks that can help alleviate these restrictions.
