[CONTRIBUTION] Add ToroDex (Sei-native perpetuals DEX) to perpetual.trades

[CONTRIBUTION] Add ToroDex (Centralized Perps on Sei) to Spellbook Perp Tables
High-level Description

ToroDex is a perpetual futures exchange that settles internally but accepts on-chain deposits and withdrawals on Sei.
We would like to contribute a Spellbook integration so that ToroDex activity can be queried consistently across the Dune ecosystem.

Because trade execution occurs off-chain, historical fills and funding data will be supplied by our public API, while on-chain deposit/withdraw activity will come from Sei contracts.

Our contribution will include:

A new torodex schema

Models for:

torodex.trades (via API ingestion)

torodex.funding_rates (via API)

torodex.positions (optional, if desired by Dune)

torodex.deposits / torodex.withdrawals (from Sei on-chain vault contracts)

Market metadata (symbol → base/quote, decimals, asset mappings)

Test cases + sample transactions

This will allow ToroDex to appear in unified perp abstractions (e.g., perp.trades), enabling ecosystem-level metrics such as volume, funding, open interest, and user activity.

Affected Sub-Projects

perp/ (primary)

labels/ (optional — trader labels based on ToroDex activity)

seichain/ (for vault deposit/withdraw parsing)

Why This Benefits the Community

Adds a Sei-native perps venue to Dune’s ecosystem

Enables dashboards for volume, funding, OI, and liquidity from ToroDex

Establishes a reusable pattern for centralized perps with on-chain settlement rails

Allows other Sei-based perp or hybrid exchanges to follow the same integration pattern

Expands coverage of the Sei ecosystem within Dune’s standardized perp tables

Lets researchers and developers analyze flows between on-chain vaults and off-chain execution venues

ToroDex users, Sei ecosystem teams, and analysts will gain full transparency into trading metrics and on-chain capital movements.

Additional Notes

We can supply a stable public API endpoint for:

historical + realtime trades

funding rates

market metadata

We can also provide example responses and schema definitions

Our vault contracts are deployed on Sei; we will include:

checksummed addresses

ABI/event schemas

example deposit/withdraw txs via explorer links

Start by reviewing the existing integrations under perp/ and seichain/, then compare their model and unified-table patterns with the proposed torodex.trades, funding_rates, deposits, and withdrawals models. The issue does not name specific files, API details, or tests; done means the supplied API and Sei vault data are integrated, tested with sample transactions, and exposed through the requested perp abstractions.
