## What is Convertible JPY Token?
What is Convertible JPY Token?
Convertible JPY Token (CJPY) is a stablecoin issued through Yamato Protocol, a decentralized lending protocol on Ethereum developed by DeFiGeek Community Japan. CJPY represents debt created when a user deposits collateral and borrows tokens. Its intended value is tied to the Japanese yen, rather than to the US dollar.
CJPY is described as ETH-overcollateralized: borrowers deposit Ether worth more than the CJPY they create. This is different from a yen-backed token whose issuer holds yen reserves for each token. CJPY’s design therefore depends on the protocol’s collateral and debt-management rules, as well as demand for the token. A stated yen peg is a target, not a guarantee that CJPY will always trade at that value.
## How CJPY is used
How CJPY is used
CJPY’s main purpose is to provide a yen-denominated asset within Yamato Protocol and the Ethereum ecosystem. Eligible users can generate it by depositing ETH as collateral and taking on a debt position. The protocol description says users pay a one-time issuance fee rather than ongoing accrued interest; check the current protocol terms before interacting, as mechanics and fees can change.
The design also describes debt positions below a 130% health rate as redeemable by other users using CJPY acquired on the market. Protocol fees accumulated in CJPY are described as supporting redemptions of under-threshold positions, with a subrogation mechanism for positions below a 100% health rate. These are protocol mechanisms, not assurances that users can always redeem at a particular price or that the token will remain liquid. CJPY is not described as a governance token or as a general-purpose payment token.
## Supply and blockchain availability
Supply and blockchain availability
CJPY is issued on Ethereum, and public sources do not identify it as the native token of any blockchain. At the time of the listed snapshot, November 5, 2026, the reported circulating supply was about 212.6 million CJPY. The same snapshot lists total supply at roughly 9.4 × 10^25 CJPY, an extraordinarily large figure compared with the circulating amount. The maximum supply is not specified.
Because the total-supply figure conflicts so sharply with the circulating figure, and the derived fully diluted valuation is not credible, treat those supply and valuation metrics as unreliable until they can be checked against the token contract and protocol records. The snapshot also reports a price of about $0.0051 and a market capitalization of about $1.1 million on that date. Those are historical, changeable figures, and a USD quote alone does not show whether CJPY is tracking its intended yen peg.
## Risks and storage
Risks and storage
CJPY carries smart-contract and protocol risks: a software flaw, oracle problem, or failure in the debt-management system could affect collateral or redemptions. ETH can fall in value quickly, weakening collateral coverage and putting borrowers’ positions at risk under the protocol’s rules. CJPY can also trade away from its yen target, and limited trading activity may make it difficult to exchange at a desired price. The inconsistent reported supply figures are another reason to verify token and protocol information independently.
CJPY is an Ethereum token, so use a wallet that supports Ethereum tokens and confirm the token contract address through Yamato Protocol’s official channels before adding or transferring it. A mistaken address or network can lead to an unrecoverable transfer. Keep your recovery phrase private, and be cautious of unsolicited messages or sites asking you to connect a wallet. Holding CJPY does not mean you hold yen in a bank account or have a guaranteed claim on yen reserves.
By the numbers
Convertible JPY Token in numbers
Convertible JPY Token (CJPY) is ranked #2,979 by market capitalisation, with a market cap of about $1.06M and a price of $0.004973 as of Nov 6, 2026. Its fully diluted valuation is $467878545935T, so roughly 0% of the eventual supply is in circulation today; tokens still to be released could add selling pressure.
The price was up 0.8% over 7 days, down 2.2% over 30 days, down 8.9% over the past year. It trades about 32% below its all-time high of $0.007364, set on Nov 9, 2023.
About 212.62M CJPY are in circulation, from a total supply of 94,086,010,348,484.55T. No hard maximum supply is listed.
24-hour trading volume was about $4.03K, or 0.4% of its market cap: low turnover, so large orders can move the price.
CJPY has token contracts on Ethereum. Always check the contract address before buying or bridging: copycat tokens often reuse a well-known name and ticker.
