- Switch from blocking RpcClient to solana_client::nonblocking for async RPC calls that won't block the tokio runtime under load - Replace .unwrap() on Mint::unpack_from_slice with proper error propagation to prevent panics on malformed data - Return HTTP 503 on RPC/parse failures instead of misleading "0" response (errors are logged internally, not exposed to clients) - Share RpcClient via Axum state instead of creating new client per request for better resource efficiency
- Use async Solana RPC client with proper error handling (503 on failure) - Share RPC client via state instead of creating per request - Add router() functions to supply and legacy modules - Simplify main.rs with clean route composition
- New endpoint: GET /api/stats/staked/{token}
- Queries PositionV0 accounts via getProgramAccounts with registrar filter
- Sums amount_deposited_native and divides by token decimals
- Background task populates cache on startup and refreshes every 15 min
- Requests block on cache miss with double-check locking to prevent parallel fetches
- Replace runtime PDA derivation with registrar constants - Use data_slice in gPA to fetch only the 8-byte amount field
