Catalyst Dex Integration

dune mcp server: user-dune-mcp. for ad-hoc sql, prefer temporary execution if the dune mcp supports it in-session. only create saved/throwaway queries with createDuneQuery when temporary execution is not available or when a later step explicitly needs a query_id. fallback sequence when query_id is required: create query with createDuneQuery (pass sql in query) -> run with executeQueryById (using returned query_id) -> fetch rows with getExecutionResults (using returned execution_id).

conventions

• execution order: numbered items = execute sequentially. any step that says "run" or "execute" is blocking; complete it before proceeding.
• code patterns: use existing chain patterns as reference (e.g. dbt_subprojects/dex/models/trades/kaia/, .../mezo/). ordering: mimic existing; if unclear, append. swap chain name in: file paths, model names, schema entries, blockchain values.
• contributors: new files: set git username only. existing files: append git username.

prep vars

• retrieve chain metadata: run this sql via the ad-hoc sql sequence above: select * from dune.blockchains where name = '<chain>' (substitute <chain> with the chain name). extract: chain_id, name (display name), token_address (native token).
• retrieve first_block_time: run this sql via the ad-hoc sql sequence above: select min(time) from <chain>.blocks where number <> 0 (substitute <chain>).

git workflow

1. verify main is up to date: fetch latest, pull if behind, exit if diverged.
2. create branch: name <issue_id>-<chain>-dex-integration, create off main, checkout, warn if exists. don't commit/push anything.

additional prep

• verify decoded dex tables exist: use dune mcp executeQueryById with query_id: 6318398, query_parameters: [{"key":"chain","value":"<chain>","type":"text"},{"key":"namespace","value":"<namespace>","type":"text"}] (substitute <chain> and <namespace>). retrieve from query results: namespace, name, and abi.
• find common events in abi following patterns like: Swap, PairCreated, and PoolCreated. if not found, query <chain>.logs_decoded.
• identify dex type: uniswap v2 fork, v3 fork, or custom.

steps

1. define DEX sources

   • create/update sources/_sector/dex/trades/<chain>/_sources.yml
   • append new sources replicating pattern from existing source blocks in that file (copy one block, replace chain/project/namespace)

2. create platform base trades model

   • create dbt_subprojects/dex/models/trades/<chain>/platforms/<project>_<chain>_base_trades.sql
   • uniswap v2 forks: use uniswap_compatible_v2_trades macro
   • uniswap v3 forks: use uniswap_compatible_v3_trades macro
   • custom DEXs: check docs; use as reference dbt_subprojects/dex/models/trades/<chain>/platforms/kuru_monad_base_trades.sql or existing macros

3. chain-level setup (new chain only)

   • create dbt_subprojects/dex/models/trades/<chain>/dex_<chain>_base_trades.sql
   • create dbt_subprojects/dex/models/trades/<chain>/dex_<chain>_trades.sql
   • create dbt_subprojects/dex/models/trades/<chain>/dex_<chain>_token_volumes_daily.sql
   • add <chain> to chains list in dbt_subprojects/dex/models/trades/dex_trades.sql
   • add <chain> to chains list in dbt_subprojects/dex/models/trades/dex_token_volumes_daily.sql

4. create/update schema file

   • create dbt_subprojects/dex/models/trades/<chain>/_schema.yml (new chain) with dex_<chain>_trades, dex_<chain>_base_trades, dex_<chain>_token_volumes_daily
   • append platform model definition to existing schema

5. create seed file

   • append <project>_<chain>_base_trades_seed to dbt_subprojects/dex/seeds/trades/_schema.yml
   • create empty dbt_subprojects/dex/seeds/trades/<project>_<chain>_base_trades_seed.csv

6. update dex_info.sql

   • if not already present, append <project> to dbt_subprojects/dex/models/dex_info.sql

7. final checks

   • From repo root: run pipenv shell, then cd dbt_subprojects/dex and dbt compile (or dbt compile --select <project>_<chain>_base_trades). Fix any errors.
   • populate seed csv: replace <COMPILED_BASE_TRADES_SQL> in the query below with the exact compiled sql for the model <project>_<chain>_base_trades (from dbt compile output). use it as a subquery, not a table name. run the full query via the ad-hoc sql sequence above and paste the 2-3 rows into the seed csv.

   with base_trades as (
     select
       blockchain, project, version, block_date, tx_hash, evt_index,
       token_bought_address, token_sold_address, block_number,
       token_bought_amount_raw, token_sold_amount_raw,
       row_number() over (partition by blockchain, project, version order by block_number desc) as rn
     from ( <COMPILED_BASE_TRADES_SQL> )
   )
   select
     blockchain, project, version, block_date, tx_hash, evt_index,
     token_bought_address, token_sold_address, block_number,
     token_bought_amount_raw, token_sold_amount_raw
   from base_trades where rn <= 3

• custom DEX: dbt_subprojects/dex/models/trades/<chain>/platforms/kuru_monad_base_trades.sql
• uniswap v2 fork: dbt_subprojects/dex/models/trades/<chain>/platforms/uniswap_v2_monad_base_trades.sql
• uniswap v3 fork: dbt_subprojects/dex/models/trades/<chain>/platforms/uniswap_v3_monad_base_trades.sql

notes

• for multi-version DEXs (v2 + v3), create separate models
• use version filter in seed test if sharing seed file
