+# Gateway SDK Extraction - Continuation Prompt
+
+**Date**: 2025-01-27
+**Current Branch**: `feature/sdk-meteora-extraction` (PR #535)
+**Overall Progress**: **62% Complete** (33/53 operations)
+**Last Completed**: Meteora DLMM (12/12 operations - 100%)
+
+---
+
+## 🎯 Quick Start
+
+You are continuing the Gateway SDK extraction project. This is a systematic effort to extract all protocol connector logic from the API layer into a reusable SDK layer.
+
+### Key Documentation Files

+
+**Current Status**:
+- **`docs/CURRENT_STATUS.md`** (this gets updated each session)
+- **`docs/CONTINUATION_PROMPT.md`** (this file - quick start guide)
+
+**Completed Work**:
+- **Raydium**: `docs/COMPLETION_SUMMARY.md`, `docs/PR_2_STATUS.md`
+- **Jupiter**: See commit `4949c87c`

+

+
+## 🚀 Next Steps - Decision Matrix
+
+### Option A: Complete 0x (Recommended for Momentum)
+
+**Time**: 4-6 hours
+**Operations**: 5 (all router-based)
+**Complexity**: Low (similar to Jupiter)
+
+**Pros**:
+- Quick win, maintains momentum
+- Router-only pattern (already proven with Jupiter)
+- Validates Ethereum chain patterns
+- Gets you to 71% completion (38/53 ops)
+
+**Reference Locations**:
+- Similar to Jupiter: `packages/sdk/src/solana/jupiter/`
+- Existing API: `src/connectors/0x/router-routes/`
+- Master plan: `docs/Protocol_SDK_PLAN.md` lines 495-536
+
+### Option B: Complete Uniswap (Highest Value)
+
+**Time**: 12-16 hours
+**Operations**: 15 (Router + AMM + CLMM)
+**Complexity**: High (three different patterns)
+
+**Pros**:
+- Most widely used protocol
+- Highest impact on project
+- Establishes all Ethereum patterns
+- Completes 91% of project (48/53 ops)
+
+**Reference Locations**:
+- Router: Similar to Jupiter/0x
+- AMM: `packages/sdk/src/solana/raydium/operations/amm/`
+- CLMM: `packages/sdk/src/solana/raydium/operations/clmm/`
+- Existing API: `src/connectors/uniswap/`

+## 📋 Standard Extraction Workflow
+
+```bash
+# 1. Create new feature branch
+git checkout main
+git pull origin main
+git checkout -b feature/sdk-{connector}-extraction
+
+# 2. Create SDK structure
+mkdir -p packages/sdk/src/{chain}/{connector}/operations/{type}
+mkdir -p packages/sdk/src/{chain}/{connector}/types
+
+# 3. For each operation:
+#    a. Read existing API route
+#    b. Define types in SDK types file
+#    c. Create SDK operation file
+#    d. Export from index.ts
+#    e. Update API route to use SDK
+#    f. Test: pnpm typecheck
+
+# 4. Commit and PR
+git add packages/sdk/ src/connectors/
+git commit -m "feat: Complete {connector} SDK extraction..."
+git push -u nfttoolz feature/sdk-{connector}-extraction
+gh pr create --repo hummingbot/gateway --base main \
+  --head NFTToolz:feature/sdk-{connector}-extraction
+```

+
+## 🎨 Established Patterns
+
+### Query Operations (Simple Async Functions)
+- **Example**: `packages/sdk/src/solana/meteora/operations/clmm/pool-info.ts`
+- **Pattern**: Async function that fetches data and returns result
+- **When**: Read-only operations
+
+### Transaction Operations (OperationBuilder Class)
+- **Example**: `packages/sdk/src/solana/meteora/operations/clmm/execute-swap.ts`
+- **Pattern**: Class with validate(), simulate(), build(), execute()
+- **When**: Operations that create/execute transactions
+
+### API Routes (Thin Wrappers)
+- **Example**: `src/connectors/meteora/clmm-routes/poolInfo.ts`
+- **Pattern**: ~30-50 lines, parameter extraction → SDK call
+- **Target**: -30% to -70% code reduction
+
+### Type Adapters
+- **Example**: `src/connectors/meteora/clmm-routes/closePosition.ts`
+- **Pattern**: Transform SDK types to API schema types
+- **When**: SDK and API types differ (for backward compatibility)

+
+## 🎯 Immediate Action Items
+
+**To Continue**:
+
+1. Choose next connector (0x recommended for momentum)
+2. Create new branch: `git checkout -b feature/sdk-{connector}-extraction`
+3. Study existing routes: `src/connectors/{connector}/`
+4. Follow established patterns from completed work
+5. Create SDK structure and extract operations
+6. Update API routes to thin wrappers
+7. Test, commit, and create PR
+
+**Current Progress**: 62% (33/53 operations)
+**Remaining**: 20 operations across 2 connectors
+**Estimated Time to 100%**: 16-22 hours (3-4 sessions)
+
+---
+
+**Last Updated**: 2025-01-27
+**Status**: Meteora complete (PR #535), ready for next connector
+**Recommendation**: Start with 0x (quick win), then Uniswap (high value)
