imtoken冷钱包转账显示长度错误,可能是区块链拥堵造成的。
解决方案:
第1步:热钱包:点击“导入钱包”->选择“以太坊钱包”->选择第四项“观察钱包”->点击右上角的扫描按钮,扫描第2步钱包地址的二维码;
第2步:冷钱包:选择你想观察的钱包地址;
第3步:热钱包:接着第1步操作,扫描未联网手机的地址二维码->点击“下一步”->生成“授权签名”的二维码;
第4步:冷钱包:使用imToken内的“扫一扫”功能,在底部选择“导入钱包”选项,扫描第3步中热钱包生成的二维码->下一步->输入密码->生成“授权签名”的二维码;
第5步:热钱包:点击第3步”授权签名”页面中的“下一步”按钮->点击“扫描授权钱包页面的二维码,导入签名”->扫描第4步中“授权成功”的二维码->点击“确定”->即可完成授权。
小知识:
1.未联网的手机成为冷钱包,里边是包含私钥信息的,所以一定要细心保管,做好冷钱包的钱包备份。
2.冷钱包一定不要联网。
3.观察钱包在没有冷钱包的离线签名情况下,是无法进行转账交易的。

『叁』 冷钱包和助记词是哪里生产的

产地瑞士。冷钱包则是离线钱包,网络不能访问到你存储私钥的位置,它是非联网的钱包。冷钱包则是依靠“冷”设备确保数字货币私钥的安全,在非联网的情况下,通过电脑、手机、写着私钥地址的小本本。例如.Ledger钱包:比特币硬件钱包制造商Ledger是数字货币安全领域技术领先的公司之一,能为消费者和企业提供值得信赖的硬件。Ledger是基于智能卡的比特币硬件钱包,提供技术领先的最高保护等级,兼具可用及操控性。
Ledger硬件钱包是一个多功能钱包,安全存储私钥的硬件设备,查看钱包和发送交易时,硬件钱包需要与软件钱包配合才能使用。同时支持安全存储比特币、以太坊及平台代币、Zcash等。其项目已经在Github上开源。基于其硬件设备,你既可以使用Ledger开发的软件钱包,也可以使用其他团队开发的软件钱包,即可以配合以太坊网页钱包MyEtherWallet或者Parity钱包使用Ledger。

一、热钱包和冷钱包的优缺点:
1、从安全方面考虑,相较而言,比特币冷钱包被黑客攻击的可能性更低,这也是为什么不少监管机构要求交易平台通过离线方式保存用户加密资产的原因。冷钱包由于不能被网络访问,避免了黑客盗取私钥的风险,只要保存得当,相比热钱包会更安全。
但如果从便捷方面考虑,联网状态下的热钱包可以随时进行资产交易,使用体验更加方便快捷。因此对于资产较大的持有者来说,冷热钱包一起使用可以在便捷操作的同时隔离风险,更好的保障虚拟货币资产安全。
2、冷钱包和热钱包都通过钱包地址来实现数字资产的交易。如何理解钱包地址呢?我们可以把它想象成你去银行开户,银行给你卡号,别人就可以通过这个卡号给你转账。一般来说,钱包地址和私钥是成对出现的,钱包地址就是你的银行卡号码,对应私钥就像你的银行卡号的密码。钱包地址记录你在该钱包地址上存有多少币,你只有在知道密码的情况下才能有资格去使用银行卡号上的钱。
3、私钥和钱包地址一样是数字资产交易中的关键要素,无论你是使用冷钱包还是热钱包储存数字资产,只要任何人知道了你的钱包私钥,就能随意转走并处置你的数字资产。总之,谁手握私钥,谁才是加密数字钱包真正的主人。因此,在使用钱包时请务必保存好它们。

『肆』 冷钱包和助记词硬件是怎么做的

通过可信任的助记词、增加灵活性。
软件冷钱包,不同于硬件冷钱包,软件冷钱包使用纯软件的方式实现冷钱包功能。用户需要使用两部手机,其中一部永久离线,作为冷钱包存储私钥(助记词)。另一部联网,作为观察钱包使用。软件冷钱包和硬件冷钱包实现同样的功能,安全级别类似。但是它们有一些显著的区别:软件冷钱包可以使用闲置手机,没有额外的硬件;硬件冷钱包通过数据线或蓝牙传输数据,而软件冷钱包通过扫描二维码。
可信任的助记词:软件冷钱包可以实现更彻底的去信任(即不需要信任软件开发者),用户可以自行证明其钱包的绝对安全性。在资产安全中,首当其冲的是助记词的安全。而在助记词的安全中,首要确认是助记词生成的随机性。如果您使用了一个作恶的硬件厂商(或者有 bug)的硬件钱包,您可能在第一步就已经陷落了。
在使用软件冷钱包时,你可选择信任软件,让其帮助您生成助记词。也可以选择不信任软件,自行在它处生成助记词。因此,软件冷钱包的助记词的安全性高于硬件冷钱包。
软件冷钱包比硬件冷钱包更加灵活。通常软件冷钱包可以实现比硬件冷钱包更加复杂的功能。软件冷钱包的灵活性,也让其在资产的恢复方面也更加有优势。如果您的硬件钱包损坏,需要购买(同一厂商)的硬件,进行硬件恢复。而使用软件冷钱包,则没有这样的顾虑。
拓展资料:
目前市场上,虽然主要的冷钱包产品依然是以硬件冷钱包为主,但是它们正在受到软件冷钱包的冲击。硬件冷钱包: Ledger 是最知名的硬件冷钱包方案提供商; Trezor 是另一个知名的硬件冷钱包提供商;软件冷钱包:Ownbit 是最早实现软件冷钱包方案的钱包,也是支持冷钱包币种最多的钱包之一; Parity Signer 是 Parity 出品的以太坊软件冷钱包; 未来 事物发展的方向永远是化繁为简。越来越多的冷钱包正在以软件的方式实现。

『捌』 什么是区块链数字资产冷钱包、热钱

比特币钱包有很多种形态,如PC或手机钱包客户端、在线网页钱包、甚至是记录了比特币私钥的小本本(纸钱包)或者大脑(脑钱包)。你可以根据需求来选择适合自己的钱包。

比特币钱包按照私钥的存储方式,可以分为冷钱包、热钱包两种。

01、冷钱包是指网络不能访问到你私钥的钱包。

冷钱包往往依靠“冷”设备确保比特币私钥的安全,比如不联网的电脑、手机、写着私钥地址的小本本等。冷钱包避免了被黑客盗取私钥的风险,但是可能面临物理安全风险,比如电脑丢失损坏等。

02、热钱包是指互联网能购访问你私钥的钱包。

热钱包往往是在线钱包的形式。使用热钱包时,最好在不同平台设置不同密码,且开启二次认证,以确保自己的资产安全。

钱包其实就是“私钥、地址和区块链数据的管理工具”。

Tips:
1. A mobile phone that is not connected to the Internet becomes a cold wallet, which contains private key information, so you must keep it carefully and make a backup of the cold wallet.
2. The cold wallet must not be connected to the Internet.
3. Observe that the wallet cannot perform transfer transactions without the offline signature of the cold wallet.

Where are 『三』 cold wallets and mnemonics produced?

Origin: Switzerland. A cold wallet is an offline wallet. The network cannot access the location where you store your private keys. It is a non-networked wallet. Cold wallets rely on "cold" equipment to ensure the security of digital currency private keys. When not connected to the Internet, they use computers, mobile phones, and small notebooks with private key addresses written on them. For example. Ledger wallet: Bitcoin hardware wallet manufacturer Ledger is one of the technology leaders in the field of digital currency security, providing consumers and businesses with trustworthy hardware. Ledger is a smart card-based Bitcoin hardware wallet that provides the highest level of technological leadership and is both usable and controllable.
Ledger hardware wallet is a multi-functional wallet, a hardware device that securely stores private keys. When viewing the wallet and sending transactions, the hardware wallet needs to be used in conjunction with the software wallet. Also supports safe storage of Bitcoin, Ethereum and Ping AnTaiwan token, Zcash, etc. Its project has been open sourced on Github. Based on its hardware equipment, you can use either the software wallet developed by Ledger or the software wallet developed by other teams. That is, you can use Ledger with the Ethereum web wallet MyEtherWallet or Parity wallet.
Extended information:
1. Advantages and disadvantages of hot wallets and cold wallets:
1. From a security perspective, in comparison, Bitcoin cold wallets are less likely to be hacked. This is also The reason why many regulatory agencies require trading platforms to store users’ crypto assets offline. Since cold wallets cannot be accessed by the network, they avoid the risk of hackers stealing private keys. As long as they are properly stored, they will be safer than hot wallets.
But if we consider convenience, hot wallets under the Internet can conduct asset transactions at any time, making the user experience more convenient and faster. Therefore, for holders with larger assets, using hot and cold wallets together can isolate risks while facilitating operations, and better ensure the security of virtual currency assets.
2. Both cold wallets and hot wallets use wallet addresses to realize digital asset transactions. How to understand the wallet address? We can think of it like you go to a bank to open an account, the bank gives you a card number, and others can transfer money to you through this card number. Generally speaking, the wallet address and the private key appear in pairs. The wallet address is your bank card number, and the corresponding private key is like the password of your bank card number. The wallet address records how many coins you have in that wallet address. You can only use the money on your bank card number if you know the password.
3. The private key, like the wallet address, is a key element in digital asset transactions. Whether you use a cold wallet or a hot wallet to store digital assets, as long as anyone knows your wallet private key, they can transfer it and transfer it at will. Dispose of your digital assets. In short, whoever holds the private key is the real owner of the encrypted digital wallet. So be sure to save them when using your wallet.

『四』How cold wallet and mnemonic hardware are made

Increase flexibility through trusted mnemonic words.
Software cold wallet is different from hardware cold wallet. Software cold wallet uses pure software to realize the cold wallet function. Users need to use two mobile phones, one of which is permanently offline, as a cold wallet to store private keys (mnemonic phrases). The other one is connected to the Internet and used as an observation wallet. Software cold wallets and hardware cold wallets implement the same functions and have similar security levels. But they have some significant differences: software cold wallets can use idle mobile phones with no additional hardware; hardware cold wallets transmit data via data cable or Bluetooth, while software cold wallets scan QR codes.
Trusted mnemonic: Software cold wallet can achieve more complete trustlessness (that is, there is no need to trust the software developer), and users can prove the absolute security of their wallets by themselves. In asset security, the first thing that bears the brunt is the security of mnemonic phrases. In the security of mnemonic words, the first confirmation is the randomness of mnemonic word generation.. If you use a hardware wallet from a rogue hardware manufacturer (or a buggy one), you may already be trapped on the first step.
When using a software cold wallet, you can choose to trust the software and let it help you generate a mnemonic phrase. You can also choose not to trust the software and generate the mnemonic phrase yourself elsewhere. Therefore, the security of the mnemonic phrase of software cold wallet is higher than that of hardware cold wallet.
Software cold wallets are more flexible than hardware cold wallets. Generally, software cold wallets can implement more complex functions than hardware cold wallets. The flexibility of software cold wallet also makes it more advantageous in asset recovery. If your hardware wallet is damaged, you need to purchase hardware (from the same manufacturer) for hardware recovery. With software cold wallets, there are no such concerns.
Extended information:
At present, although the main cold wallet products in the market are still hardware cold wallets, they are being impacted by software cold wallets. Hardware cold wallet: Ledger is the most well-known hardware cold wallet solution provider; Trezor is another well-known hardware cold wallet provider; Software cold wallet: Ownbit is the first wallet to implement software cold wallet solution and supports the most cold wallet currencies One of the wallets; Parity Signer is an Ethereum software cold wallet produced by Parity; The direction of future development of things is always to simplify the complex. More and more cold wallets are being implemented in software.

『五』Why is it unrealistic to withdraw coins from wbf exchange to Ethereum cold wallet

The cold wallet will be offline (not connected to the network) and only used for transactions signature authorization.
A cold wallet is a wallet that stores your cryptocurrency off the Internet. For example, the wallet file generated on the ETHTT wallet website is added with a password, private key, and mnemonic phrase, and is stored away from the network. You can store it in a USB flash drive.

『8』What are blockchain digital asset cold wallets and hot money

Bitcoin walletThere are many forms, such as PC or mobile wallet clients, online web wallets, and even small notebooks (paper wallets) or brains (brain wallets) that record Bitcoin private keys. You can choose a wallet that suits you based on your needs.

Bitcoin wallets can be divided into cold wallets and hot wallets according to the storage method of private keys.

01. A cold wallet refers to a wallet where your private key cannot be accessed by the network.

Cold wallets often rely on "cold" devices to ensure the security of Bitcoin private keys, such as computers, mobile phones, and small notebooks with private key addresses written on them that are not connected to the Internet. Cold wallets avoid the risk of private keys being stolen by hackers, but may face physical security risks, such as computer loss and damage.

02. Hot wallet refers to a wallet that can access your private key via the Internet.

Hot wallets are often in the form of online wallets. When using hot wallets, it is best to set different passwords on different platforms and enable secondary authentication to ensure the security of your assets.

A wallet is actually a "management tool for private keys, addresses and blockchain data."
