# Solana indexing

> Tracked owners and token sources, parsed balances, deterministic identity, and current Solana limitations.

The Solana indexer observes configured settlement wallets and sources, requests recent signatures, loads parsed transactions, and derives supported token movement from pre/post token balances.

## Supported assets

* USDT mint with 6 decimals and operational USD price 1
* USDC mint with 6 decimals and operational USD price 1

Sources can represent an owner, associated token account, token account, or manual address. `SOLANA_ADDITIONAL_SOURCE_ACCOUNTS` can add deployment-specific sources without hardcoding them.

## Status handling

Confirmed observations are eligible for reporting and pairing. Failed transactions are retained as `FAILED` for visibility but excluded from pairing. Deterministic identities prevent the same observation from creating duplicate transfers.

## Current limitations

The configured signature limit bounds each source scan. Production still needs durable historical pagination/checkpoints, more complete source discovery, Token-2022 coverage, and an automatic retry worker for durable failure records. Public RPC history may be incomplete or throttled; production requires reliable archival providers.
