catalyst gas and transfers

overview

sets up gas fees and token transfers for a new chain.

when to use: use when adding gas and token transfer models for a chain that already has foundational metadata.

parameters

• <issue_id>: linear issue id (e.g., CUR2-547)
• <chain>: chain name (e.g., monad)

usage

/catalyst-gas-and-transfers CUR2-547 monad

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>-gas-and-transfers, create off main, checkout, warn if exists. don't commit/push anything.

additional prep

• identify native token_address: run this sql via the ad-hoc sql sequence above: select * from dune.blockchains where name = '<chain>' (substitute <chain>).

steps

1. add gas fees model

   • check chain docs: L1 or L2/rollup?
   • query <chain>.transactions for sample gas fees setup
   • create dbt_subprojects/hourly_spellbook/models/_sector/gas/fees/<chain>/gas_<chain>_fees.sql
   • L1: use evm_l1_gas_fees macro
   • L2: use op_stack_gas_fees or arbitrum_orbit_stack_gas_fees
   • if non-applicable: write custom logic

2. add gas schema

   • create dbt_subprojects/hourly_spellbook/models/_sector/gas/fees/<chain>/gas_<chain>_schema.yml

3. add gas seed data

   • edit dbt_subprojects/hourly_spellbook/seeds/_sector/gas/evm_gas_fees.csv
   • use dune mcp executeQueryById with query_id: 6162940, query_parameters: [{"key":"chain","value":"<chain>","type":"text"}] (substitute <chain>) for test entries

4. add to gas fees union

   • edit dbt_subprojects/hourly_spellbook/models/_sector/gas/fees/gas_fees.sql
   • add <chain> to both chain lists

5. create transfer models

   • create dbt_subprojects/tokens/models/transfers_and_balances/<chain>/ with:
     • tokens_<chain>_base_transfers.sql
     • tokens_<chain>_transfers.sql
     • tokens_<chain>_net_transfers_daily.sql
     • tokens_<chain>_net_transfers_daily_asset.sql
       • set native_contract_address = var('ETH_ERC20_ADDRESS') or chain-specific
     • tokens_<chain>_transfers_from_traces.sql
     • tokens_<chain>_transfers_from_traces_base.sql
     • tokens_<chain>_transfers_from_traces_base_wrapper_deposits.sql

6. add transfers schema

   • create dbt_subprojects/tokens/models/transfers_and_balances/<chain>/_schema.yml
   • define all 7 models with tests and column descriptions

7. add to transfers unions

   • dbt_subprojects/tokens/models/transfers_and_balances/tokens_transfers.sql
   • dbt_subprojects/tokens/models/transfers_and_balances/tokens_net_transfers_daily.sql
   • dbt_subprojects/tokens/models/transfers_and_balances/tokens_net_transfers_daily_asset.sql

8. add to transfers macro

   • dbt_subprojects/tokens/macros/transfers_from_traces/transfers_from_traces_exposed_blockchains_macro.sql

9. final checks

   • From repo root: run uv sync --locked, then run uv run dbt compile in dbt_subprojects/tokens and in dbt_subprojects/hourly_spellbook. Fix any errors.
