I can provide you with an article explaining what could cause a problem with your SafetransferFrom ERC721 without message.
Understanding ERC721 Safe Transpress
The “Safetransferfrom” function is a decisive part of the ERC721 standard, which allows a safe and transparent NFT transfer between accounts. Here’s a high -level overview of what this feature does:
- It takes an account that has already been sent by NFT (recipient) and an account that wants to accept it (buyer).
- If both conditions are met, the NFT will transfer from the sender’s address to the buyer address.
- Transmission is carried out in a way that prevents handling of the transferred data.
Problem: You come back without message
When you call a “Safetransferfrom” without any mistakes or warning, the Ethereum intelligent contract will be returned with an error message. However, if there are no mistakes and is still returning, it means that something has happened under the contract.
There are several possible reasons why “Safetransferfrom” can unexpectedly return:
* Invalid recipient address : If the recipient’s account does not have enough ether (ETH) to pay for the NFT, the contract will be returned. This could happen if someone attempts to transfer the NFT from a zero balance account.
* Insufficient storage space : The sender’s account does not have to have enough storage space for NFT data storage. This may happen if the contract is deployed in an environment with a low part or if the sender does not have sufficient ETH.
* Incorrect from address from 'and Na
: If the recipient's address does not match what the intelligent contract is expecting, it will return. Make sure that the addresses “from” andat” are correct.
Example of the case of use and tuning steps
To better understand where your code could go wrong, we recommend that you create a simple test case to reproduce the problem:
`Solidity
Import * as et z ‘@ethersproject/ethers’;
contract Simplecer721Transfer {
// deploy an ERC721 contract in the Ethereum network.
Deployment () Public Returns (Address) {address) {
// Suppose you have an ERC721 contract.
Address NewACCOUNT = 0x123456789012345678901234567890;
Return NewAccount;
}
Safetransferfrom function (address sender, address recipient) public {
Require (sender! = null && recipient! = null, “Sender and recipient must be addresses”);
demand (et_storage_size (Newaddress)> = 110 * 18, “Insufficient storage”);
// provided you have the balance of the ETH for the contract.
demand (msg.value> = newaddress.balanceof (newaccount), “not enough ether”);
// deploy your NFT contract using ABI and address.
}
MINTNFT function () public {
// NFT disabling should be done safely!
}
}
`
In this example, the “deployment” is no-op (just returns the address of the deployed contract), because in fact we do not assume nothing. You can replace it with your own implementation for the extraction and transmission of NFT.
To tune the problem:
* Check the contract storage : Make sure you have enough ETH to store the data transferred.
* Verify the recipient’s address : Double check that the addresses `from ‘and’ to” match what an intelligent contract is expecting.
* Check error message : Look at the Revert message to understand the exact cause of the problem.
Conclusion
Building the NFT market may be difficult, but it is necessary to identify the root cause when problems occur. By understanding the functionality of ERC721 safe transmission and tuning technique, you will have better equipment to solve common problems in your process of developing intelligent contracts.
