Ripe Protocol

Summary

Ketju does not approve Ripe under its class rule for protocols on unapproved chains: the venue the yield survey observes settles on Robinhood Chain, which Ketju does not approve. Ripe lends its GREEN stablecoin against a whole portfolio of mixed collateral, with weighted terms for each asset. We made no finding on how well Ripe is run.

Review triggers
• A material Ripe venue on an approved chain appears in the yield survey, at which point collateral admission, oracle pricing, liquidation and GREEN redemption require their own review
• Ketju changes its verdict on Robinhood Chain

Ketju checks this memo every night and opens a review if its venues or files show a warning or a cited document changes. The first confirmation is due 2026-12-15.

Research

How it works

Ripe accepts crypto, yield-bearing positions, tokenized stocks and NFTs as combined backing for a single GREEN loan, with weighted terms for each asset class. A lender or depositor is therefore exposed to the weakest collateral in a mixed book and to the liquidation process that must price and sell it. Every one of those transactions settles on the chain under the contracts.

Size and holdings

The DefiLlama protocol API, read on 2026-09-15, classed Ripe Protocol as Lending and reported about $932k across Base and Robinhood Chain. DefiLlama listed it on 2026-02-02 with no recorded audit. The yield survey the same day observed Ripe pools on Robinhood Chain only. Base is approved with limits, but the yield survey observed no Ripe pools there, so Ketju lists Base in the review triggers and does not treat it as an available venue.

Who controls it

Robinhood Chain sits under liquidation, oracle pricing and withdrawal for the observed venue, and its controls apply to every position there at once. Collateral that includes tokenized stocks and NFTs raises pricing and salability questions that a liquidation must settle under stress. No audit is recorded for the protocol.

Withdrawals

An sGREEN holder redeems at any time in one transaction at the current rate, with no delay, penalty or cooldown, according to Ripe’s documentation. Token-level pauses or blocklists on GREEN or sGREEN can block a redemption, and the documentation does not say who controls them. A borrower withdraws collateral after repaying GREEN, and each withdrawal re-values the whole position at live oracle prices. Ripe sets live terms onchain and points to its Params site.

Class rule

Ketju does not approve any protocol under the class rule for protocols on unapproved chains while the rule stands. The rule covers the structure and makes no finding about this protocol’s quality. It does not tell an advisor what a client should hold. The review triggers list the events that would lead Ketju to review the rule or this protocol again.

Each claim above comes from one of these sources. Where Ketju could not verify a number, the memo states that.

The asset and the chain

This memo covers the protocol. A position also holds an asset and settles on a chain. Whichever of the three holds the most power over the position decides who can freeze it. These tables describe control and do not judge quality.
