Coffer

Summary

Ketju does not approve Coffer under its class rule for liquidity pools: a depositor holds a multi-asset liquidity position whose mix rebalances against traders. Coffer is a Solana exchange whose pools hold up to ten weighted tokens, with liquidity concentrated into configurable ranges. Solana is a chain Ketju approves with limits, so the class rule decides. We made no finding on how well Coffer is run.

Review triggers
• Ketju changes its class rule for liquidity pools
• Coffer publishes an audited single-asset claim whose redemption does not depend on pool composition at withdrawal

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.

How it works

Coffer pools hold as many as ten tokens at configurable weights. They use virtual balances so providers can concentrate liquidity inside a price range. A provider therefore owns a basket whose mix rebalances against traders across that range, and its redemption value depends on where the price sits at withdrawal. That is the same claim the class rule for liquidity pools covers, with more assets and a narrower range.

Size and holdings

The DefiLlama protocol API, read on 2026-09-15, classed Coffer as Dexs and reported about $115k, all on Solana. DefiLlama listed it on 2026-05-15 with no recorded audit. The yield survey the same day placed every observed Coffer pool under the class rule for liquidity pools. Solana is approved with limits, so the chain is not the reason for the verdict.

Withdrawals

When the price leaves the chosen range, concentrated liquidity turns into the weaker asset of the pair, and a ten-asset weighted pool multiplies the ways that can happen. The pool creator sets the swap fee and the protocol fee share for each pool, so a provider’s return depends on those settings. No audit is recorded, which limits the contract evidence available for any deeper review.

Class rule

Ketju does not approve any protocol under the class rule for liquidity pools 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.

Sources

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.
