Founders Fund, the venture firm tied to Peter Thiel, led a $5 million token purchase in DeFi protocol Anvil. 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.
After the deal was announced, ANVL rose more than 83% in a single day, and its market capitalization briefly reached about $109 million.
The purchase was for tokens, not equity
One detail stands out in the structure of the transaction. Founders Fund bought ANVL tokens rather than equity in the company behind Anvil. The tokens came from Anvil’s existing treasury, and no new tokens were issued.
Anvil is not a lending protocol
The clearest way to understand Anvil is to start with what it is not. It is not a lending protocol in the mold of Aave or Compound. In those systems, 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. That LOC acts as verifiable economic backing, showing that the holder has enough assets behind them to honor a financial commitment.
Letters of credit are one of the oldest tools in commercial finance. In the banking model, a buyer’s bank promises payment to a seller once the seller presents the required documents. Trillions of dollars in global trade rely on that structure.
Anvil is trying to move that logic on-chain while removing the bank as intermediary. 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 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 use cases disclosed so far center on proving that funds exist and have been locked, rather than borrowing against them.
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 can guarantee final settlement even if the underlying blockchain still needs time to confirm the transaction. That gives the merchant immediate confirmation that payment is guaranteed.
Instant exchange deposits
Bullish is exploring Anvil for instant margin deposits. Under a standard process, traders moving assets from an external wallet have to wait for on-chain confirmation. With Anvil’s letter of credit, the exchange can extend trading capacity as soon as the assets are locked in the vault.
Business-to-business credit support
Anvil’s SDK allows companies to integrate the protocol without writing blockchain code. Consensus and Bitcoin.com were also listed as partners.
Across these examples, the common thread is simple: nothing needs to be borrowed. What matters is proving that the assets are there and cannot be moved elsewhere.
A zero-fee model built around governance
Anvil does not charge transaction fees at the protocol level, a design choice that sets it apart from most DeFi protocols.
That also means the protocol does not generate direct revenue. Its economic model rests 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 token’s value is not tied to fee sharing, because there are no protocol fees to distribute. The thesis is that if Anvil becomes infrastructure for commercial credit guarantees, governance over that infrastructure could carry value.
That is a long-duration bet. If usage scales materially, governance rights may become scarce and valuable. If usage stays limited, those rights may not amount to much.
TVL and token price remain far below prior highs
As of publication, Anvil’s total value locked on DefiLlama was about $14 million. That figure is modest, but it ranks first in the collateral management category and accounts for more than 90% of the category’s total TVL. The category itself is still very small, with only two tracked protocols.
The historical trend is more revealing. 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 83% one-day jump tied to this announcement, the token remains in a historically low range.
What Founders Fund is actually betting on
Founders Fund did not buy into another standard DeFi lending token. The purchase is a bet that on-chain letters of credit can grow into a category large enough to stand alongside on-chain lending.
In size, the position is limited. The article notes that Founders Fund completed a $6 billion raise in May 2026, its largest fundraising round on record, so a $5 million purchase looks more like an exploratory position. Even so, Joey Krug’s direct endorsement and Robert Leshner’s personal participation give the deal more signaling weight than the dollar amount alone.
What to watch next
- How many companies actually integrate Anvil after the SDK rollout. Among the names listed so far — Flexa, Bullish, Consensus and Bitcoin.com — Flexa is the only one described as having completed deep integration.
- Whether the zero-fee model can hold up over time. Treasury tokens may support development for now, but over the longer run the protocol may need some form of fees, or a higher ANVL price, to fund the team.
- Whether there is enough real on-chain demand for letters of credit. Traditional letters of credit support trillions of dollars in commerce, but how much of that demand moves on-chain will depend on the pace of enterprise crypto adoption.
