我正在尝试在 rinkeby 测试网络上测试智能合约功能，它将多个代币迁移到新合约。即我想烧掉 ERC-721 代币（将它们发送到烧毁地址），这些代币存储在 Opensea 合约上，然后在新合约上重新进行。

当我在本地以太坊网络分支（使用 ganache-cli）上测试该功能时，一切正常，但在 rinkeby 网络上，我收到以下错误：

在 Etherscan.io 上，我在“状态”下收到此附加错误消息：

Fail with error 'AssetContractShared#_requireMintable: ONLY_CREATOR_ALLOWED'

这是我正在调用的智能合约功能。Opensea(openseaSharedAddress).safeTransferFrom(msg.sender, burnAddress, oldIds[j], 1, "");当我用函数删除for循环时它工作正常

function batchMigration(uint256[] memory oldIds, uint256[] memory newIds, bytes32[] memory leaves, bytes32[][] memory proofs) external {
        for (uint i = 0; i < oldIds.length; i++) {
            // Don't allow reminting
            require(!_exists(newIds[i]), "Token already minted");

            // Verify that (oldId, newId) correspond to the Merkle leaf
            require(keccak256(abi.encodePacked(oldIds[i], newIds[i])) == leaves[i], "Ids don't match Merkle leaf");

            // Verify that (oldId, newId) is a valid pair in the Merkle tree
            //require(verify(merkleRoot, leaves[i], proofs[i]), "Not a valid element in the Merkle tree");

            // Verify that msg.sender is the owner of the old token
            require(Opensea(openseaSharedAddress).balanceOf(msg.sender, oldIds[i]), "Only token owner can mintAndBurn");
        }

        for (uint j = 0; j < oldIds.length; j++) {
            Opensea(openseaSharedAddress).safeTransferFrom(msg.sender, burnAddress, oldIds[j], 1, "");
        }
    }

这里是我调用批量迁移功能的 web3 部分：

await smartContract.methods
           .batchMigration(oldIds, newIds, leaves, proofs)
           .send({
               from: walletAddress, //accounts[0]
               gasLimit: 6721975,
           }).on('transactionHash', function (hash) {
                console.log(hash)
           });

在我调用批量迁移函数之前，我正在设置 ApprovalForAll，所以这应该不是问题：

await openseaContract.methods.setApprovalForAll(SMART_CONTRACT_ADDRESS, true).send({
            from: walletAddress,
        });

有谁知道为什么会发生此错误？谢谢

我遇到了同样的问题，经过一番测试，我可以找到解决方案。

正如我刚刚在这里发布的https://ethereum.stackexchange.com/questions/111077/error-execution-reverted-assetcontractsharedcreatoronly-only-creator-allowed，合约在转移令牌之前调用铸币函数。调用铸币函数会导致调用修饰符，该修饰符本身会检查 tokenOwner。

解决方案是检查令牌是否已被铸造并铸造，然后才能通过其他地址（已批准）转移。

  • 测试代币余额
  • 如果没有余额，请先铸造（来自转账账户）
  • 然后你可以 setApprovalForAll
  • 那么转移应该有效
