[Devnet] USDC oracle (spot/0 - PythLazerStableCoin) stale for 40+ hours — all orders failing with error 6003

[rafaelneiva]

Environment

• Network: Solana Devnet
• Gateway version: latest master (1.5.5)
• Startup: ./drift-gateway --dev https://api.devnet.solana.com --markets btc-perp,usdc --verbose

Problem

All order placements fail with {"code":6003,"reason":"InsufficientCollateral"}
despite having $10,000 USDC in collateral.

Root cause: the oracle for spot/0 (USDC) is completely stale.

Oracle Discrepancy — SDK vs On-chain

Source	Oracle Address (spot/0)	Type
SDK spotMarkets.ts	En8hkHLkRe9d9DraYmBTrus518BvmVH448YcvmrFM6Ce	PYTH_STABLE_COIN_PULL
On-chain (gateway logs)	9VCioxmni2gDLv11qufWzT3RDERhQE4iY5Gf7NTfYyAV	PythLazerStableCoin ← STALE

The address the SDK defines for spot/0 appears on-chain as spot/6 with type PythStableCoinPull.

Oracle Delay Progression

Time (UTC)	Delay
2026-03-08 03:35	250,753 slots (~27h stale)
2026-03-08 11:04	321,292 slots (~35h stale)
2026-03-08 22:51	still stale, no recovery

Test Output

  ✗ HTTP 400 → {"code":6003,"reason":"InsufficientCollateral"}

[7] Oracle Health check
  ⚠ Oracle STALE — spot/0 (USDC) PythLazerStableCoin
  ⚠ Address: 9VCioxmni2gDLv11qufWzT3RDERhQE4iY5Gf7NTfYyAV
  ⚠ Impact: margin calculation returns ~$1.3B required vs $10k available

Result: Gateway PASS | Collateral PASS | Market PASS | Order FAIL | Oracle WARN

Confirmed working (not the issue)

• Collateral: $10,000.14 USDC free ✓
• All read endpoints return HTTP 200 ✓
• BTC-PERP oracle (perp/1, PythLazer) healthy ✓
• --markets btc-perp,usdc resolves correctly ✓

Questions

1. Is the Pyth Lazer feed for 9VCioxmni2gDLv11qufWzT3RDERhQE4iY5Gf7NTfYyAV going to be restored on devnet?
2. Is devnet actively maintained post-V3 launch?
3. Should spotMarkets.ts be updated to reflect the actual on-chain oracle address?
