✨ January 15, 2026 - Solana DeFi SDK Optimization & Drift Perps

TL;DR: Removed all heavy Solana DeFi SDKs (Drift, Solend, MarginFi, Meteora, Raydium) and replaced them with raw batched RPC calls, drastically reducing RPC costs. Added Kamino lending and Drift perpetuals support.

SDK Removal & RPC Optimization

The Wallet DeFi Positions endpoint (/api/2/wallet/defi-positions) has been completely refactored to eliminate heavy SDK dependencies:

Removed SDKs

SDK	Before	After
`@drift-labs/sdk`	Heavy bundle, many RPC calls	Raw RPC with batched account reads
`@solendprotocol/solend-sdk`	Sequential RPC calls	Batched `getMultipleAccounts`
`@marginfi/marginfi-client-v2`	Complex initialization	Direct account deserialization
`@meteora-ag/dlmm`	Multiple RPC roundtrips	Single batched request
`@raydium-io/raydium-sdk-v2`	Heavy dependencies	Pure CLMM math implementation

Performance Benefits

~70% reduction in RPC calls per wallet query
Faster response times due to batched account fetching
Lower memory footprint without heavy SDK bundles
No SDK initialization overhead per request

New Protocol Support

Kamino Lending

The endpoint now supports Kamino lending positions:

{
  "protocol": {
    "id": "kamino",
    "name": "Kamino",
    "category": "lending"
  },
  "positions": [
    {
      "type": "deposit",
      "name": "USDC Supply",
      "valueUSD": 5000.00,
      "tokens": [...],
      "metadata": {
        "apy": "8.5",
        "collateralEnabled": true
      }
    }
  ]
}

Drift Perpetuals

Full support for Drift perpetual positions is now available:

{
  "protocol": {
    "id": "drift",
    "name": "Drift",
    "category": "perps"
  },
  "positions": [
    {
      "id": "drift-perp-0-subaccount-0",
      "type": "leverage",
      "name": "drift-sol-usd LONG",
      "valueUSD": 1250.50,
      "metadata": {
        "marketId": "drift-sol-usd",
        "exchange": "drift",
        "side": "BUY",
        "entryPriceQuote": 180.5,
        "currentPriceQuote": 185.2,
        "currentLeverage": 5.2,
        "liquidationPriceQuote": 145.8,
        "amountUSD": 6500.0,
        "unrealizedPnlUSD": 250.50,
        "unrealizedPnlPercent": 20.04
      }
    }
  ]
}

Wallet DeFi Positions

All existing integrations remain backwards compatible. The response format is unchanged - only the underlying implementation was optimized.
