Alchemix V2 Review 2026: Superseded by V3 Self-Repaying Loans

Alchemix V2 is a version of the Alchemix protocol, which issues synthetic tokens that represent the future yield of a deposit. Users could take loans against ETH or stablecoin deposits, and the yield generated would pay the debt down over time. DeFiLlama tracks it under Synthetics across Ethereum, Optimism, Arbitrum and Fantom.

The V2 bridge and governance pages now say the migration to V3 is complete and direct users to the main Alchemix site for the new vaults. Tracked TVL for V2 is only about $82,725. For that reason this page treats V2 as superseded, and the live product is the current Alchemix app.

The protocol is one of the older names in DeFi and has its own token, ALCX, and a DAO. Its homepage lists two audits, open-source code and a footer warning that DeFi tools are not toys.

Alchemix lets users borrow against a deposit without selling it. A user deposits collateral, which the protocol places into yield-generating strategies. The user can then mint a synthetic token, an alAsset, up to a set share of the deposit's value.

As the collateral earns yield, that yield is applied to the outstanding debt. In the best case the loan shrinks without the borrower making payments. The pace depends on the yield earned, so it is not fixed, and the borrower can also repay manually.

The Transmuter helps keep alAssets close to their peg. Holders can redeem alAssets for the underlying asset 1:1 over a period. The homepage describes a newer mechanism in which redemptions are earmarked and settle after a fixed time, shrinking alAsset supply and pushing the price toward 1.00. Those details describe the current Alchemix system, not necessarily V2 as it originally ran.

Alchemix advertises 0% interest on its loans for the current app. The material reviewed does not publish a full fee schedule for V2, including any protocol fees on yield or redemptions.

Users also pay network gas on whichever chain they use, and fees can change with the vault and strategy. The current app and the protocol docs are where up-to-date figures would be shown.

Alchemix lists two audits, publishes open-source code and documentation, and says it prioritises capital preservation with defined risk controls. The homepage also states that no guarantees are given and that users act at their own risk. Audits lower risk but cannot rule out bugs or failures in the integrated yield protocols.

Custody is non-custodial, since users connect their own wallet. The main risks are smart-contract risk, dependence on external yield sources, and alAsset peg risk. The material reviewed names no licence or regulatory status for the project, and it does not describe any specific past exploit.

Because V2 has been superseded, users with old positions should follow the official migration guidance and avoid unofficial links.

This page suits readers who hold or held a V2 position, or who are researching the history of self-repaying loans. New borrowers interested in the concept should look at the current Alchemix app and its documentation instead of V2.
