The UMA community has officially launched its first synthetic token, ETHBTC, marking a significant milestone in decentralized finance (DeFi). Approved by community governance on Tuesday, the ETHBTC synthetic contract is now live on Ethereum’s mainnet. This innovative token tracks the price ratio between Ethereum (ETH) and Bitcoin (BTC), enabling users to gain exposure to the relative performance of the two leading cryptocurrencies — without owning either.
What Is the ETHBTC Synthetic Token?
The ETHBTC token represents the value of ETH relative to BTC. For example, if ETH is trading at $200 and BTC at $10,000, the ETHBTC ratio would be 0.02. As this ratio changes over time — whether ETH outperforms BTC or vice versa — so does the value of the ETHBTC token.

This token operates as a time-bound financial instrument, set to expire on August 1, 2020. Upon expiration, each ETHBTC token will be redeemable for DAI based on the final reported price ratio between ETH and BTC. For instance, if the ratio settles at 0.03, each token holder receives 0.03 DAI per token.
Unlike traditional derivatives, ETHBTC is fully decentralized and built on UMA’s "priceless" financial design — a novel mechanism that minimizes reliance on oracles by using economic incentives and dispute resolution only when necessary.
How Does the Priceless Design Work?
UMA’s priceless protocol architecture is at the heart of this innovation. Most DeFi derivatives depend heavily on oracles to provide continuous price feeds. However, oracles introduce centralization risks and potential attack vectors.
In contrast, the ETHBTC token leverages UMA’s Data Verification Mechanism (DVM). Instead of querying oracles throughout the token’s lifecycle, the system assumes honest behavior unless a dispute arises. Only at expiration does the DVM report the final ETH/BTC price ratio — drastically reducing oracle usage and enhancing security.
This makes ETHBTC the first mainnet DeFi product to implement such a design in production. It serves as a real-world experiment to test whether financial contracts can function with minimal oracle interaction while maintaining trustlessness and accuracy.
Who Can Create or Mint ETHBTC Tokens?
One of the most powerful aspects of this launch is its permissionless nature. Any user on the Ethereum blockchain can interact with the ETHBTC smart contract to mint new tokens.
To do so, a user must act as a sponsor — locking up DAI as collateral to back newly minted ETHBTC tokens. The protocol enforces a 120% collateralization ratio, meaning sponsors must deposit sufficient DAI to cover potential payouts at maturity.
When a sponsor mints and sells an ETHBTC token, they effectively take a short position on the ETH/BTC ratio. If ETH strengthens against BTC, the token value rises — increasing the sponsor’s risk. Hence, maintaining adequate collateral is essential to avoid liquidation.
Developers and advanced users can interact with the contract directly using UMA’s open-source command-line interface (CLI) or build custom tools via the published APIs and verified contract code on Etherscan.
How to Acquire ETHBTC Tokens
For traders and investors looking to gain long exposure to the ETH/BTC ratio, acquiring ETHBTC tokens is straightforward.
A liquidity pool for ETHBTC/DAI has been deployed on Uniswap v2, allowing seamless trading. At launch, the token was trading around 0.02 DAI, reflecting current market sentiment on Ethereum’s performance relative to Bitcoin.

Liquidity providers can also participate by adding funds to the pool, earning trading fees in return. As interest grows, deeper liquidity could enhance price stability and reduce slippage for larger trades.
Core Keywords and SEO Focus
This article centers around several key concepts essential for search visibility and audience reach:
- Synthetic tokens
- DeFi derivatives
- ETHBTC ratio
- UMA protocol
- Priceless design
- Oracle minimization
- Permissionless minting
- Collateralized debt positions
These terms naturally appear throughout the content to align with user search intent — whether someone is researching how to trade crypto ratios, exploring UMA’s tech stack, or studying innovations in oracle efficiency.
Risks and Important Considerations
While groundbreaking, the ETHBTC token is labeled as an experimental alpha release. Despite undergoing a comprehensive audit by OpenZeppelin, one of the most respected firms in blockchain security, it remains a decentralized product with no central control — not even by UMA’s core team.
As such:
- There is no customer support or recovery mechanism.
- Smart contract bugs or unexpected market conditions could lead to losses.
- Sponsors must actively monitor their collateral levels.
- The economic model has not yet been stress-tested under extreme volatility.
Users are strongly advised to proceed with caution, especially when minting or providing liquidity.
Frequently Asked Questions (FAQ)
Q: What happens if I hold ETHBTC past August 1, 2020?
A: The token expires on that date. After settlement via the DVM, you can redeem your tokens for DAI based on the final ETH/BTC ratio. Holding beyond expiry offers no additional value.
Q: Can I use other assets as collateral instead of DAI?
A: No. Currently, only DAI is accepted as collateral for ETHBTC minting. Future synthetic tokens may support alternative stablecoins or assets.
Q: Why is oracle usage minimized in this design?
A: Reducing oracle calls lowers dependency on external data sources, mitigating risks like manipulation or downtime. The DVM only activates during disputes or at expiry, improving security and efficiency.
Q: How is the final price determined at expiration?
A: The UMA Data Verification Mechanism (DVM) polls registered voters to report the correct ETH/BTC price ratio. This decentralized oracle ensures truthfulness through incentive alignment.
Q: Is there a cap on how many ETHBTC tokens can be minted?
A: No. As long as users provide sufficient DAI collateral and meet margin requirements, anyone can mint new tokens — making supply dynamic and demand-driven.
Q: Where can I verify the smart contract code?
A: The fully audited and verified contracts are available on Etherscan, allowing developers and auditors to inspect logic and ensure transparency.
