feat: add Anemoy Capital yield adapter - #2961
Conversation
Anemoy issues JTRSY, the Janus Henderson Treasury Fund - a tokenized
short-dated US Treasury fund distributed through Centrifuge ERC-7540
async vaults. Listed for TVL since 2025 but with no yields coverage.
JTRSY is a fixed-balance ERC-20; yield accrues through NAV, exposed as
pricePerShare() on the vault the LTF contract returns for USDC. Same
valuation path the TVL adapter uses.
- tvlUsd : LTF.totalSupply() x pricePerShare, priced at the USDC rate.
Resolves to $870.7M, matching the TVL adapter.
- apyBase : realised pricePerShare growth over a trailing 7-day window,
annualised. Currently 3.49%, and stable across windows
(3.48% / 30d, 3.60% / 90d, 3.43% / 180d) - the right level
for short-duration US Treasuries.
NAV is fund-level so it is read once on Ethereum and applied to each
chain's float, as the TVL adapter does. Base and Celo carry the
contracts but hold zero supply, so only the Ethereum pool publishes.

📝 WalkthroughWalkthroughAdds a DefiLlama yield adapter for Anemoy Capital’s JTRSY fund. The adapter calculates TVL across Ethereum, Base, and Celo, and reports validated seven-day annualized APY when historical NAV data is available. ChangesJTRSY yield tracking
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The adapter may publish substantially overstated TVL if a token-decimals read fails, and its Base and Celo token metadata uses the Ethereum USDC address. These are localized correctness issues that should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Skip the chain when decimals() fails.
call(...).catch(() => null) returns null for an RPC failure. Number(null) returns 0. If totalSupply() succeeds while decimals() fails, Line 117 treats raw token units as whole tokens and can overstate TVL by 10 ** actualDecimals. Check for a missing decimals result before converting it.
Proposed fix
const supply = Number(supplies[i]);
- const dec = Number(decimals[i]);

Anemoy JTRSY LTF 0x8c213ee79581ff4984583c6a801e5263418c4b86 Base Celo USDC vault asset
💡 Result:
The token address 0x8c213ee79581ff4984583c6a801e5263418c4b86 corresponds to the Janus Henderson Anemoy Treasury Fund, represented by the symbol JTRSY [1][2]. Key details regarding this asset include: Asset Transformation: JTRSY is the rebranded and evolved version of the former Anemoy Liquid Treasury Fund (LTF) [3]. Nature of the Asset: It is a regulated, tokenized, actively managed fund that provides on-chain access to US Treasury yields (specifically targeting <6 month US Treasury bills) [4][5]. Technical Deployment: The contract 0x8c213ee79581ff4984583c6a801e5263418c4b86 is the primary ERC-20 token address for JTRSY [2][6]. While it is deployed across multiple blockchains—including Ethereum, Base, and Celo—the same contract address is often cited as the canonical identifier for the token across supported networks [7]. Operational Details: Issuer: Anemoy, with Janus Henderson Investors serving as the sub-investment manager [5]. Regulation: The fund is a professional fund regulated by the British Virgin Islands Financial Services Commission (BVI FSC) [4][5]. Subscriptions/Redemptions: The fund utilizes USDC for subscriptions and redemptions [5]. Eligibility: Access typically requires KYC verification and is intended for professional/institutional investors [6][5]. Please note that this token is distinct from other Anemoy-related vault products, such as the Janus Henderson Anemoy AAA CLO Fund token, which uses a different contract address [8].

"vault(address)" "function selector"
💡 Result:
There is no standard or unique function signature titled "vault(address)" in the Ethereum ecosystem, and therefore no single universal function selector for it [1]. In Solidity, a function selector is the first 4 bytes of the Keccak-256 hash of a function's signature [1][2]. If you need the selector for a function named vault(address), you can calculate it using the following steps: 1. Define the function signature string: "vault(address)" [1]. 2. Compute the Keccak-256 hash of this string: keccak256("vault(address)") [1]. 3. Take the first 4 bytes of that hash [1]. You can calculate this value using a tool like Cast or a Python script: # Using Foundry's cast tool cast sig "vault(address)" # Output: 0x4864c8d5 Note that function names like "vault" are often used in many different smart contracts for various purposes, and the presence of a function selector is specific to the contract ABI (Application Binary Interface) it belongs to [1][3]. If you are looking for a selector from a specific project, ensure you are referencing that project's documentation, as different vaults implement unique functions (e.g., enableVault(address) which has the selector 0x936f4330) [4][1][5].

"0x27e8c820d05aea8824b1ac35116f63f9833b54c8" JTRSY USDC
💡 Result:
The token address 0x27e8c820d05aea8824b1ac35116f63f9833b54c8 corresponds to the Janus Henderson Anemoy Treasury Fund (JTRSY) token deployed on the Celo blockchain [1][2]. JTRSY is a tokenized share in a British Virgin Islands (BVI) professional fund that invests in short-term U.S. Treasury bills [3][4]. The token serves as prima facie evidence of ownership in the fund, and it is not a stablecoin, despite being denominated in USD and utilizing USDC for subscriptions and redemptions [4]. During the subscription and redemption process, the fund interacts with Circle to convert USDC to USD at a 1:1 ratio to facilitate the purchase of Treasury assets offchain [5][4]. JTRSY is deployed across multiple blockchains, and the contract address varies by network [2]: - Celo: 0x27e8c820d05aea8824b1ac35116f63f9833b54c8 [1][2] - Ethereum, Arbitrum, and Base: 0x8c213ee79581ff4984583c6a801e5263418c4b86 [2] - Plume, BNB Chain, and Avalanche C-Chain: 0xa5d465251fbcc907f5dd6bb2145488dfc6a2627b [2][6] Investors should be aware that JTRSY is an institutional-grade financial product subject to eligibility controls and specific administrative processes [2][3][4].

Centrifuge JTRSY Celo settlement asset USDC contract 0xceBA9300
💡 Result:
The contract address 0xceBA9300f2b948710d2653dD7B07f33A8B32118C on the Celo network is the official contract for Circle's USD Coin (USDC) [1][2][3]. JTRSY (Janus Henderson Anemoy Treasury Fund) is a tokenized Real World Asset (RWA) fund built on Centrifuge infrastructure [4][5]. It allows professional, whitelisted investors to gain exposure to short-duration U.S. Treasury bills [6][7]. The fund utilizes USDC as its primary settlement asset for subscriptions and redemptions [8][4][6]. When investors subscribe to the fund, they transfer USDC to a specified smart contract, which atomically mints the JTRSY tokens [8][5]. Conversely, during the redemption process, the smart contract facilitates the payout of USDC to the investor after the underlying Treasury securities are sold and processed [8][4]. The address 0xceBA9300 is frequently referenced in technical contexts on Celo as the standard USDC gateway for such protocols, including Centrifuge's operations, to enable these tokenized asset transactions [9][10].

The address 0xceBA9300f2b948710d2653dD7B07f33A8B32118C is the official contract address for USD Coin (USDC) on the Celo blockchain [6][7][8]. For clarity, here are the correct details for both entities: Janus Henderson Anemoy Treasury Fund (JTRSY) The JTRSY token serves as digital evidence of ownership in a BVI-regulated fund [3][9]. It is tokenized via the Centrifuge protocol [2][10][5] and is generally found on Ethereum, Base, Arbitrum, and other networks using the contract address 0x8c213ee79581Ff4984583C6a801e5263418C4b86 [4][2][5]. USDC on Celo The address 0xceBA9300f2b948710d2653dD7B07f33A8B32118C is the proxy contract for the native USDC stablecoin deployed on the Celo network by Circle [6][11][8].

💡 Result:
JTRSY is the ticker symbol for the Janus Henderson Anemoy Treasury Fund, a tokenized investment vehicle focused on short-term U.S. Treasury bills [1][2]. The fund is a key asset within the Centrifuge ecosystem [1][3]. The string "0xceBA9300" refers to a partial hex identifier associated with Centrifuge-related technical documentation or contract-related data [4]. While the provided string is incomplete (typically, Ethereum-style addresses are 42 characters long, including the '0x' prefix and 40 hexadecimal characters), it often appears in contexts where developers or indexers are configuring asset identities or registry mappings for various Centrifuge pools and vaults [4][5]. In the context of the Centrifuge protocol: - JTRSY: Represents the Janus Henderson Anemoy Treasury Fund [1][3]. - Technical Identification: Assets in Centrifuge (such as JTRSY) are tracked across different chains (e.g., Ethereum, Base, Celo, Arbitrum) and are often identified by their chain, contract address, and ERC-6909 token ID [6][5]. Developers working with the Centrifuge API or protocol frequently manage these configurations, and incomplete or placeholder-like strings like "0xceBA9300" may appear in code repositories, pull requests, or indexer configurations where specific asset address mappings are being defined, corrected, or referenced [4][6][5]. For the most accurate and up-to-date address information, you should refer to the official Centrifuge deployment repository at github.com/centrifuge/liquidity-pools/tree/main/deployments [7].

Adds a yields adapter for Anemoy Capital (slug
anemoy-capital, listed for TVL, adapterprojects/anemoy-capital/index.js).Anemoy issues JTRSY, the Janus Henderson Treasury Fund — a tokenized fund holding short-dated US Treasuries, distributed through Centrifuge's ERC-7540 asynchronous vaults. It's ~$871M of TVL with no yields coverage today.
Output
TVL resolves to $870.68M against the TVL adapter's $870.70M — same valuation path, so the two agree.
Methodology
JTRSY is a fixed-balance ERC-20; it does not rebase. Yield accrues through the fund's NAV, exposed as
pricePerShare()on the vault that the LTF contract returns for a given settlement asset (USDC).tvlUsdistotalSupply() × pricePerShare, priced at the USDC rate fromcoins.llama.fi— deliberately the same pathprojects/anemoy-capital/index.jsuses to value the token, so TVL can't drift between the two adapters.apyBaseis realisedpricePerSharegrowth over a trailing 7-day window, annualised. It's the fund's actual accrual, not a projection or an off-chain rate. The result is stable across window lengths, which is the sanity check that matters for a treasury fund:That's the right level for short-duration US Treasuries.
Notes
NAV is read once on Ethereum and applied to every chain's float, mirroring
getNav()in the TVL adapter, which does the same. It's a single fund-level number — the per-chain deployments differ only in how much of the float sits there.Only Ethereum publishes a pool. Base and Celo carry the LTF contracts but currently hold zero JTRSY supply, so they're filtered rather than emitted as empty pools. If float moves to those chains they'll appear automatically with no code change.
Guard: if the archive read for the prior window fails, or the window shows no growth, the pool publishes
tvlUsdwith noapyBaserather than failing the adapter or asserting a rate it can't evidence.🤖 Generated with Claude Code
