加速保管闪电钱包扩大了代币产品，包括USDT之后包括USDC

基本上，这个世界上只有三种真正的货币：比特币，黄金和美元。这些货币中存储或传输价值（无论是欧元，白银还是以太）的所有其他物品。

The custodial Lightning Node wallet Speed has added the stablecoin USDC to its wallet. It is the strongest stablecoin after Tether's dollar and, unlike Tether, it is licensed for operation in the EU.

托管雷电节点钱包速度已将Stablecoin USDC添加到其钱包中。它是系绳美元以后最强的稳定币，与Tether不同，它是在欧盟运营的。

Speed wallet users can deposit USDC not just via Lightning, but also via Ethereum. If you have USDC as ERC20 tokens, you can easily transfer the tokens into the Lightning Network with a simple transaction. Alternatively, you can swap bitcoin for USDC.

Speed Wallet用户不仅可以通过闪电来存入USDC，还可以通过以太坊存入。如果您将USDC作为ERC20代币，则可以通过简单的交易轻松地将令牌转移到闪电网络中。另外，您可以将比特币交换为USDC。

Speed wallet now displays balances in three currencies.

速度钱包现在以三种货币显示余额。

Once USDC is in your wallet, you can send it to any other wallet that accepts it. Or you can swap it for bitcoin, allowing Speed to facilitate native dollar token-to-native bitcoin exchanges within the Lightning Network itself.

一旦USDC放在您的钱包中，您就可以将其发送给其他接受它的钱包。或者，您可以将其交换为比特币，从而允许速度促进闪电网络本身内的本地美元到本地比特币交换。

The technical foundation for the USDC-L tokens is the Taproot Assets protocol, developed by Lightning Labs. It anchors tokens into the “leaves” of the “hash tree” at the core of each Taproot transaction, providing the advantage of functioning both on-chain and off-chain within Lightning. Speed had already brought Tether's USDT to the wallet as a Taproot Asset back in August.

USDC-L代币的技术基础是由Lightning Labs开发的Taproot资产协议。它将令牌固定在每个Taproot交易的核心的“哈希树”的“叶子”中，从而提供了在闪电内部链和链上运行链的优势。 Speed已经将Tether的USDT带到了钱包，这是八月份的Taproot Asset。

The user experience is impressive: depositing tokens is simple and fast; transfers, as well as swaps, are possible in real time. One could argue that stablecoin integration was the final touch Lightning needed to go mainstream.

用户体验令人印象深刻：存放令牌简单快捷；转移以及掉期是实时的。有人可能会说，Stablecoin集成是成为主流所需的最终触摸闪电。

However, there are two caveats: First, neither USDT nor USDC tokens are widely supported across Lightning wallets. Besides Speed, only AquaWallet and Uxuy support USDT on Lightning; for LNBits, there is at least a plugin for Taproot Assets enabling reception of such tokens. Almost a year after Lightning Labs announced the protocol, it remains an exception rather than the norm for wallets to support these assets.

但是，有两个警告：首先，USDT和USDC令牌均未得到闪电钱包的广泛支持。除速度外，只有Aquawallet和Uxuy支持USDT在闪电上；对于LNBITS，至少有一个用于Taproot资产的插件，可容纳此类令牌。闪电实验室宣布该协议近一年后，它仍然是一个例外，而不是支持这些资产的钱包的规范。

Second, Speed is a custodial wallet. Without custody, neither swaps nor deposits from Ethereum would be possible. Unfortunately, this means users do not have control over their bitcoin and dollars. Speed is also obliged to collect users’ private data and share it during transactions—and if it refuses, it would likely not be permitted to operate in most jurisdictions.

其次，速度是一个保管钱包。没有监护权，以太坊的掉期和存款都是不可能的。不幸的是，这意味着用户无法控制自己的比特币和美元。速度还有义务收集用户的私人数据并在交易期间共享，如果拒绝，则可能不允许在大多数司法管辖区进行操作。

Currently, Speed is registered in Dubai, where it is legally able to operate in this manner. This might work for a while, but at any time Speed may have to change its policies or even block EU residents. For this reason, only small amounts—play money—should be entrusted to the wallet; it’s possible that Speed could be compelled to freeze user funds.

当前，Speed已在迪拜注册，在该迪拜可以通过这种方式进行合法运行。这可能会持续一段时间，但是在任何时候，速度可能必须更改其政策，甚至阻止欧盟居民。因此，只有少量的钱（玩钱）可以托付给钱包。速度可能被迫冻结用户资金。

All in all, stablecoins on Lightning hold significant potential. They enable a bitcoin wallet to support dollars, allow (in theory) real-time, trustless swaps between bitcoin and dollars, and make it possible to send dollars quickly and custodial-free around the world. For this potential to be realized, it should become the standard—not the exception—for Lightning wallets to recognize dollar tokens. This is especially true for robust, non-custodial Lightning wallets such as Phoenix. Otherwise, the decentralized revolution may end up being little more than an update for banking apps.

总而言之，闪电上的稳定蛋白具有巨大的潜力。它们使比特币钱包能够支撑美元，从理论上讲（理论上）实时，在比特币和美元之间无信任的互换，并可以在全球范围内快速和无保管的钱发送美元。为了实现这一潜力，它应该成为闪电钱包以识别美元令牌的标准。对于坚固的非习惯闪电钱包（例如凤凰）来说尤其如此。否则，分散的革命最终可能只是银行应用程序的更新。
