stabble-clmm: read swaps from the CLMM program instead of the dead API#8436BhariGowda wants to merge 4 commits into
Conversation
The CLMM product has stopped, and its stats API is gone, so there is nothing left for this adapter to read. It has been throwing a 404 on every run since, which is why volume stops at 2026-06-28. On chain, program 6dMXqGZ3ga2dikrYS9ovDXgHGh5RUsb2RTUj6hrQXhk6 (from stabbleorg/clmm Anchor.toml) is still deployed and executable, but getSignaturesForAddress shows its last transaction was 2026-06-30T09:42:57Z, and the final burst that day failed with Custom:6019. Nothing since, 26 days. DefiLlama's own TVL for stabble-clmm is now 41 USD, drifting down from 42 over the past week, so the pools are empty rather than dormant with funds in them. mclmm-api.stabble.org returns 404 on every path including the root, and including /clmm-configs, which the currently shipped clmm.stabble.org frontend still calls. That is the whole API Gateway deployment being undeployed, not one route moving. No replacement exists: the sibling AMM's host api.stabble.org/metric is alive but is the AMM's own numbers, unaffected by pool/product query params, and the docs carry no API reference. Note this only stops the daily failures. Dates before 2026-06-30 still cannot be re-fetched, since the API is gone entirely, so existing stored history stays as it is and no backfill is possible either way. The AMM adapter at dexs/stabble is unaffected and still reporting. Tests: 2026-07-22 404 error -> skipped, "is dead (deadFrom 2026-06-30)" 2026-06-20 still 404, the API is gone for historical dates too dexs/stabble 2026-07-22 unchanged, revenue 1.00, supply side 1.33
Summary by CodeRabbit
WalkthroughThe Stabble CLMM adapter now processes Solana transactions and account data on-chain. It decodes swaps and computes volume, fees, protocol revenue, and supply-side revenue using pool fee rates. The adapter also supports hourly pulls and includes methodology metadata. ChangesStabble CLMM on-chain metrics
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The adapter currently omits protocol and holder revenue breakdowns and may misreport volume, fees, and revenue when on-chain amounts exceed JavaScript’s safe-integer range. These are bounded but concrete data-correctness issues, so the PR is not merge-ready until they are corrected or explicitly accepted. Suggested labels: Sequence Diagram(s)sequenceDiagram

Fair enough, that's on me. 28 days with no announcement from the team doesn't clear that bar and deadFrom was the wrong reach. Agreed on moving it on-chain. One correction to my own PR body while I'm here, because I was sloppy. I wrote "last transaction was 2026-06-30". The last successful transaction was 2026-06-30T09:42:56Z ( So it decayed rather than stopped, which is another reason deadFrom with a single cutoff date was the wrong shape for this. On the rebuild: the program is a Raydium CLMM fork, so it emits the standard Anchor I'll read amounts and the fee split from the program itself and drop the |
mclmm-api.stabble.org 404s on every path, so the adapter had no source left. Rather than mark it dead, read the CLMM program directly. The program is a Raydium CLMM fork, so each swap emits an anchor SwapEvent as a `Program data:` log line. Walk the program's signatures for the window, pull the transactions, and decode the events that were emitted while the program was the executing frame. Other CLMM forks share the event discriminator and a single Jupiter route can touch several of them, so the frame check is what keeps foreign swaps out. Fees come from the trade_fee_rate on each pool's AmmConfig, read live, and revenue is protocol_fee_rate plus fund_fee_rate of that.

Checked 2026-03-06 specifically rather than assuming it was the same divergence I already flagged. Two findings settle it. 1. The stored number is larger than the pools could physically have traded that day. Vault balances on the pools that had any activity on 2026-03-06, read from the token balances in that day's own transactions: Every other pool was untouched that day. Current TVL for stabble-clmm is $41.88. The stored value for that day is 138,932, against roughly $100 of quote liquidity. That is not a discrepancy to reconcile, it is not reachable. 2. The program's own lifetime counters cap total volume well below what the stored series claims.
5.7x more stored than the program has ever processed. By month: Stored March is 369,363 on its own, more than double the program's entire lifetime volume, in a month with 232 successful transactions across the whole program. I verified the counters are trustworthy before leaning on them, by summing every What 2026-03-06 actually was 51 transactions touch the program, all successful, none failed: An LP bot rebalancing, and one trade. The trade is Both candidate windows, since the stored point at that key covers the previous day: I also confirmed the adapter is not missing transactions on that day, by building the same day's set from a completely separate index: all 17 pool accounts plus their 34 vaults, paged individually. 51 signatures either way, 0 present in the pool/vault index and absent from the program index. Zero of the 51 had truncated logs. There were two 205-byte frames carrying that discriminator that day, and the second one belongs to So this is the 2026-06-25 case from the PR description again, on a day with a much larger number, plus the aggregate view showing it was not confined to isolated days. Same conclusion, more of it, not a new problem. Pagination, checked rather than assumed CodeRabbit flagged that Depth from the tip:
Separate feasibility note, not a correctness caveat On the default |
The fetch derives its window from options.startTimestamp/endTimestamp and returns only the balances, with no timestamp field, which is the version 2 shape. fees/GUIDELINES.md shows version 2 as the standard for a non-Dune adapter, so the version: 1 declaration was just wrong. Re-ran after the change: solana volume 0, fees 0, revenue 0, supply side 0, same as before. The program has no swap activity in the window, which is the condition the PR discussion already established.

Took the I did not add On the signature paging comment, I am leaving it as is, with reasoning rather than a flat no: The concern is that I also did not want to reach for If the program comes back to life this becomes a real problem and the paging needs to change. I would rather that be a follow-up against live traffic that can actually be measured than a speculative cursor implementation I cannot exercise today. |

Closes #8434.
Rewritten. The first version of this PR marked the adapter dead; per @bheluga's note that
deadFromneeds an official closure announcement or many months of abandonment, and this has neither, that was the wrong call. This reads the program on-chain instead.What changed
mclmm-api.stabble.org404s on every path including the root, so the old adapter had no source left. The adapter now reads the CLMM program6dMXqGZ3ga2dikrYS9ovDXgHGh5RUsb2RTUj6hrQXhk6directly: page the program's signatures for the window, pull those transactions, and decode the anchorSwapEventeach swap emits as aProgram data:log line.Fees are the
trade_fee_rateon each pool'sAmmConfig, read live per run rather than baked in. Revenue isprotocol_fee_rate + fund_fee_rateof the fee and supply side is the remainder. On the pool that is still liquid those are 2500 / 150000 / 40000 ppm, so 0.25% fee split 81% LPs, 15% protocol, 4% fund.dexs/stabble(the AMM) is untouched.api.stabble.org/metricstill returns 200, only the CLMM API is gone.Verification
The program is a Raydium CLMM fork, so
SwapEventis 205 bytes with discriminator40c6cde8260871e2, which issha256("event:SwapEvent")[..8]. ThePoolStatefield order matches the IDL thatprojects/stabble-clmm/index.jsalready relies on for TVL.The decode is checked against the program's own accumulators.
PoolStatecarries lifetimeswap_in_amount_token_0/1andswap_out_amount_token_0/1. Summing everySwapEventa pool ever emitted should reproduce them exactly, and it does, to the raw unit:3FdD48r2bKxM6RwkQ7RJ83BrriqjRLs7iJcCyUUvB5k35gsQxEeqVfzneSpYSwC7tyUF9vdapTWC3ssEHKKpjRPZBH6zpxtYjY4AtJduxJk1mkRH2XpDZSbQRjPNfQGSnSXvThe fee math is checked against the fee split the program logs for itself. Across all 58 single-swap transactions on 2026-04-01,
trade_fee_rateapplied to the swapped amount matchesstep_fee_amount + state.protocol_fee + state.fund_feefrom theend,log line within integer rounding (worst case 2 raw units on dust swaps), and theAmmConfigrates equal theprotocol_fee_rate/fund_fee_ratethe program logged on every one.The frame check in
getSwapEventsis not decoration. On 2026-04-01 alone, other programs in the same transactions emitted that identical discriminator, in both 205 and 170 byte forms. Matching on the discriminator without checking which program is executing would pull in other CLMM forks' swaps.Signature coverage was checked from the other direction too. Across every pool account's own history there are 54,652 successful pool-touching transactions; 54,633 appear in the program's signature index. I pulled all 19 that did not: every one is System Program account setup that never invokes the CLMM program and emits no event.
What it reports
Zero today is the correct answer, not a failure. The last successful transaction on the program was 2026-06-30T09:42:56Z and there has not been one since, though the program is still being hit and failing. Successful transactions per month over its whole life, from the first one on 2025-10-15:
If swaps resume the adapter picks them up on its own with no further change.
The numbers the old API was returning do not match the chain
Worth flagging since it is what we have been storing:
2026-06-25 is the clearest one: there were no successful transactions at all that day, confirmed both from the program's signature index and independently from every pool account's own history, yet 1,426 was recorded. I am not claiming to know why, only that the API's output was not backed by swaps on this program, and that is a second reason not to keep depending on it.
One thing I would like a maintainer's call on
Cost. Today this is one
getSignaturesForAddresspage per run and no transaction fetches, because nothing is happening. At the January peak it would have been roughly 1,600getTransactioncalls a day, and a backfill of an old date has to page back from the tip through the program's 92,078 lifetime signatures. It throws rather than under-report if it cannot get through. I did not setisExpensiveAdaptersince it is currently free, but say the word and I will.I left
startat 2025-12-12 rather than moving it back to the first on-chain swap on 2025-10-15, to avoid asking for a backfill nobody wants.
