Founders Fund led a $5 million purchase of ANVL tokens in DeFi protocol Anvil on Oct. 6, according to TechFlowPost. Other participants included Pantera Capital, Theta Blockchain Ventures, Bullish (NYSE: BLSH) and Protoscale Capital. Individual investors included Compound founder Robert Leshner, now CEO of Superstate, and Celo co-founder Rene Reinsberg.
ANVL rose more than 83% on the day the deal was announced, and its market capitalization briefly reached about $109 million.
The structure of the transaction stood out. Founders Fund bought ANVL tokens rather than equity in the company behind Anvil, and the tokens came from Anvil’s existing treasury rather than a new issuance.
Anvil is not a lending protocol
The article frames Anvil by first explaining what it is not. It is not a lending protocol like Aave or Compound, where users deposit assets as collateral, borrow another asset, pay interest and face liquidation if collateral values fall.
Anvil does something else. Users lock ETH or USDC into an Anvil vault and receive an on-chain letter of credit, or LOC. The LOC acts as verifiable economic backing that shows the holder has enough assets to stand behind a financial commitment.
Letters of credit are a long-established financial tool in traditional commerce. In the bank model, a buyer’s bank promises payment to a seller once the seller provides the required documents. The article notes that trillions of dollars in global trade rely on that structure.
Anvil moves that logic on-chain and removes the bank from the middle. Users lock their own assets, smart contracts verify whether collateral remains sufficient, and counterparties can check the status of the letter of credit in real time.
Joey Krug, a partner at Founders Fund and co-founder of Augur, said in the announcement: 「Businesses need to know that the commitments behind payments and credit will be honored. Anvil lets them back those commitments with verifiable digital asset collateral.」
Where the protocol is being used
The article points to several live or in-progress use cases, centered on payment guarantees, instant exchange deposits and business-to-business credit support.
Payment guarantees
Flexa, the crypto payments network previously co-founded by Tyler Spalding, integrated its Capacity v3 system with Anvil in March 2025. When a merchant accepts a crypto payment through Flexa, Anvil’s letter of credit guarantees final settlement. That means the merchant can receive confirmation that payment is guaranteed even if the underlying blockchain still needs time to finalize the transaction.
Instant exchange deposits
Bullish is exploring Anvil as a way to enable instant margin deposits for traders. Under the standard process, assets sent from an external wallet cannot be used until on-chain confirmation arrives. With Anvil’s letter of credit, the exchange could extend trading capacity as soon as the assets are locked in the vault.
Enterprise credit support
Anvil’s SDK allows companies to integrate the protocol without writing blockchain code. Consensus and Bitcoin.com were also listed as partners.
The common thread across these examples is simple: users do not need to borrow anything. They need to prove they have funds, and that those funds are locked and cannot be moved elsewhere.
No protocol fees, governance as the economic core
Anvil does not charge transaction fees at the protocol level. That sets it apart from most DeFi protocols.
Without fees, the protocol does not generate direct revenue. Its economic model depends on the governance value of the ANVL token. Token holders vote on which collateral types the protocol supports, how letter-of-credit parameters are set and which external contracts can connect to the system.
ANVL has a total supply of 100 billion tokens, with about 80 billion currently in circulation. The article says the token’s value does not come from protocol revenue sharing, because there are no fees to distribute. The thesis is that governance becomes valuable if Anvil turns into infrastructure for commercial credit guarantees. If usage remains limited, that governance right may carry little weight.
TVL and token price show the scale of the challenge
At publication, Anvil’s TVL on DefiLlama was about $14 million. That is not a large figure in absolute terms, but it ranked first in the collateral management category and accounted for more than 90% of the category’s total TVL. The article adds that the category itself is still tiny, with only two tracked protocols.
The historical trend is more striking. In July 2025, Anvil’s TVL reached a peak of about 36,000 ETH, or roughly $109 million. It has since fallen to about $14 million, a decline of around 87%.
ANVL was trading at about $0.00098, down roughly 89% from its all-time high of $0.0093 on Jan. 3, 2025. Even after the more than 83% one-day jump tied to the announcement, the token remained near historical lows.
What Founders Fund is betting on
The article argues that Founders Fund did not buy into just another DeFi lending token. The bet is on whether on-chain letters of credit can become a category on the scale of on-chain lending.
In size, the position is modest for Founders Fund. TechFlowPost notes that the firm completed a $6 billion fundraise in May 2026, its largest ever, making the $5 million purchase look more like an exploratory position. Even so, Joey Krug’s direct endorsement and Robert Leshner’s personal participation gave the deal more signaling value than its dollar size alone.
Key variables to watch
How many companies actually integrate Anvil after the SDK rollout. Among the named partners — Flexa, Bullish, Consensus and Bitcoin.com — Flexa is the only one the article describes as having completed deep integration.
Whether a zero-fee model can hold up over time. The article says treasury tokens can support development at the current stage, but over the longer run the protocol may need some form of fee, or ANVL may need to appreciate enough to fund the development team.
Whether there is enough on-chain demand for letters of credit. Traditional letters of credit support a market worth trillions of dollars, but how much of that demand moves on-chain depends on the pace of enterprise crypto adoption.
