Solana's $750 million stablecoin casting statement is inconsistent with on-chain data

核心要点

Circle 铸造了 5 亿 USDC,而非 2.5 亿。
两次铸造均进入同一个标记为“金库”的账户。
账户余额的大部分增加额仍保留在该账户中。
独立的 5 亿 USDT 铸造记录尚未得到验证。
流通供应量并未随总发行量上升。

链上数据证实 Circle 铸造了 5 亿 USDC

9 月 19 日的一份报告称,Solana 网络注入了总计 7.5 亿美元的稳定币,其中 Tether 贡献了 5 亿美元,Circle 贡献了 2.5 亿美元。然而,相关的底层交易证据揭示了不同的事实。

底层交易数据显示,Circle 在大约 40 分钟内完成了两笔各 2.5 亿的 USDC 铸造。Solana 的交易记录证实了这两次转账:

  • 第一次 USDC 铸造:2.5 亿 USDC,9 月 19 日 UTC 时间 10:36
  • 第二次 USDC 铸造:2.5 亿 USDC,9 月 19 日 UTC 时间 11:13

这两次铸造均指向同一个账户。该账户在第一笔交易前的余额约为 5.33 亿 USDC,在第二笔交易后升至约 10.3 亿 USDC。至 9 月 20 日 UTC 时间 12:00,该账户持有约 9.98 亿 USDC。与铸造前的余额相比,这 5 亿 USDC 的增加额中,约有 4.65 亿仍留在该账户中。尽管有约 3500 万流出,但由于代币的可互换性,账本无法区分新铸造的单位与该账户中原有的 USDC。

Creating a USDC and distributing it are two separate events.

The minting act expands the supply of tokens recorded in the blockchain, but this does not prove that customers purchased tokens, exchanges received tokens, or funds entered decentralized finance (DeFi) applications.

A more appropriate analogy is warehouse inventory: production is complete, but retail demand is not yet established before the inventory is moved to customers or distributors.

What verified transactions show

Created: Circle minted 500 million USDC on Solana.
Storage: Most of the increase in the account balance remains in the receiving account.
Distribution: Transfers to external wallets will show that inventory is being released.
Usage: Exchange deposits, DEX transactions, or loan deposits will show where this liquidity has gone.

Another reason why not equate every chain-level minting with fresh money is that Circle's Cross-Chain Transfer Protocol transfers USDC by destroying USDC in the source chain and minting the same amount in the target chain. This process may increase the supply of USDC on Solana, but not the total supply of USDC globally.

The two records on September 19 were SPL token mints directly deposited into an account marked "Treasury" and were not completed transfers to identifiable external customers. Therefore, its ultimate economic purpose cannot be determined based on the foundry transaction alone.

Reported amount of Tether still outstanding

同一份报告将另外 5 亿代币归因于 Tether。然而,报告和其底层覆盖内容均未提供匹配的 Solana 交易哈希值,且此处审查的可用证据未能独立验证该铸造行为。

DefiLlama 在 9 月 19 日和 9 月 20 日的每日快照显示,Solana 上的总铸造 USDT 供应量在这两天均接近 38.4 亿代币。同一数据集估计流通中的 USDT 约为 21.2 亿,并将约 17.2 亿归类为未发行。

DefiLlama 的公共 Solana 表使用估计的流通供应量来计算稳定币市值。38.4 亿这个数字是原始总供应量,包括数据提供商归类为未发行的代币。原始报告将约 38.4 亿 USDT 描述为“流通”,但这实际上匹配的是 Solana 代币铸造的原始总供应量,而非 DefiLlama 的流通估计值。在两天的快照中,DefiLlama 的三个字段(铸造、流通、未发行)均未记录到 5 亿 USDT 的净增加。

这并不能排除日内铸造随后被销毁的可能性。这意味着,在被计入 7.5 亿美元事件之前,声称的 Tether 部分需要交易哈希或发行方确认。

Tether 自己的 FAQ 也解释说,为补充库存而创建的代币可以保留在其金库中,状态为“已授权但未发行”。即使经过验证的 Tether 铸造也需要第二步:确定代币是保留在库存中还是已发行给客户。

供应估算讲述了不同的故事

DefiLlama's USDC data further distinguishes between token creation and circulation. The following data compares its snapshots of 00:00 UTC on September 19 and September 20, so the first reading was earlier than the two verified casts, and the second reading followed closely.

USDC supply on Solana September 19 September 20 Total casting supply 7.38 billion USDC 8.02 billion USDC Estimated circulating supply 7.03 billion USDC 6.96 billion USDC Unissued supply 354 million USDC 1.06 billion USDC

During the daily interval, total USDC minted increased by approximately 637 million tokens, approximately 137 million more than the two mints identified. Such differences may reflect other supply activities or data adjustments within the same measurement window.

More important to the term "liquidity injection" is that the estimated circulating supply fell by approximately 73 million USDC, while the unissued category increased by approximately 710 million. According to DefiLlama's methodology, net expansion is not included in the circulation supply to customers.

These estimates are not a substitute for tracking each wallet transfer, and third-party classifications may also change. However, they refute the simple claim that "Foundry automatically puts full funds into Solana's active market."

Can trading activity prove inflows? This alone is not enough to prove

铸造后更高的去中心化交易所(DEX)交易量看起来像是支持性证据,但交易量衡量的是周转率,而非进入网络的净资本。同一批稳定币可以反复易手,从而产生更大的交易量数字。

在这些铸造发生之前,Solana 已经重新回到每日 DEX 排名榜首,尽管其每日交易量仍低于上周的水平。因此,随后的交易量上升需要在钱包级别提供证据,才能与 newly created USDC 联系起来。

对交易所余额和借贷存款也适用同样的谨慎态度。总量的上升可以支持分布理论,但如果无法追踪从标记为“金库”的账户到这些场所的转账,它就无法识别来源。

什么会改变结论

证明代币进入活跃市场的证据:

  • 从接收账户向交易所、做市商或 DeFi 协议的大额转账
  • Solana 上估计的流通 USDC 供应量持续增加
  • 发行方确认客户发行(而非库存准备)导致了这些铸造
  • 声称的 5 亿 USDT 铸造的可验证 Solana 交易
  • 目的地钱包活动将新供应与交易或借贷流动性联系起来

即使出现这些信号,也不能证明稳定币发行导致 SOL 或其他资产上涨。它们只能建立一个更狭窄但也更有用的观点:新创建的代币是否真正可用于市场。

下一个接收者比铸造本身更重要

已验证的交易显示 Circle 在 Solana 上准备了 5 亿 USDC。它们并没有显示 7.5 亿美元的流动性注入,而单独的 5 亿 USDT 声明缺乏将其纳入事件的所需交易证据。

如果 USDC 从金库库存转移到外部钱包,并且估计的流通量上升,结论可能会改变。在此之前,代币的目的地——而不是铸造公告的规模——是新流动性是否到达市场的清晰测试标准。
