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; tools query_sql, run_query_by_id. Use parameters as shown.

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: use Dune MCP query_sql with query: 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: use Dune MCP query_sql with query: 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: use Dune MCP query_sql with query: 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 run_query_by_id with query_id: 6162940, query_parameters: '{"chain":"<chain>"}' (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 pipenv shell, then run dbt compile in dbt_subprojects/tokens and in dbt_subprojects/hourly_spellbook. Fix any errors.
