Copy-trading infrastructure for mirroring target wallets across Solana DEX ecosystems.
The validator listens to high-value actors, reconstructs their instructions, and rebroadcasts optimized copies with custom compute budgets and priority fees for near-zero-slot confirmations.

• Multi-DEX Coverage – Supports Pump.fun spot trades, LaunchLab primary sales, Raydium AMM / CPMM / CLMM pools, and custom PumpSwap events.
• Slot-Optimized Execution – Builder pipeline pre-calculates compute-unit budgets and tip pricing for faster inclusion (observed 0–1 block settlements).
• 0-Block Copy Transactions – Supports near-instant transaction mirroring for Pumpswap, CPMM, and AMM protocols with optimized routing.
• Auto-Sell Logic – Automated position management with take profit, stop loss, trailing stop loss, and lifetime-based selling.
• Resilient Signature Watcher – Deduplicates source signatures and replays with configurable cooldowns to avoid double-spends.
• Accounts Auto-Wiring – Instruction builders expand Anchor PDAs such as fee_config, global_volume_accumulator, and event authorities.
• Modular Instruction Decoders – Each program family (Pumpfun, Raydium, LaunchLab) exposes ArrangeAccounts adapters to translate raw transactions into actionable instructions.
• Operational Telemetry – Timestamped logging per event, including time-to-submit, decode summaries, and RPC outcomes.

All processors implement carbon_core::processor::Processor, enabling plug-and-play registration with the carbon pipeline.

1. Install Rust toolchain (rustup, nightly not required).
2. Fetch dependencies:

   cargo fetch

3. Start the monitor:

   cargo run --release

4. Watch logs for decoded events (time-stamped with latency measurements). Successful mirrors print the encoded transaction signature or RPC error payload.

The pipeline keeps a rolling cache of processed source signatures to protect against replay.

• Detects TradeEvent inner instructions, reconstructs account PDAs (user, bonding curve, fee config).
• Auto-creates idempotent ATAs before buys; closes empty ATAs after sells.
• Computes target token/SOL amounts using bonding curve virtual reserve math (sol_token_quote, token_sol_quote).
• Example mirrored sells (Slot + confirmation in <2 ms):
  • Tx 4UmB7mFvdmT34UoE…
  • Tx 35CJF142B2srWpKp…

• Replays LaunchLab sell-side exits with proper fee routing and ATA wiring.
• Includes fee tier PDAs (fee_config, fee_program) to satisfy latest Anchor constraints.
• Example mirrored sells:
  • Tx 5jVbrTJRPAKW6ETQ…
  • Tx 663Lw1W1iaJTEbmD…

• Decoders map swap events to SwapBaseIn, SwapBaseInput, and SwapV2 flows.
• Automated ATA derivations (via derive_associated_token_address) and quote lookups for size calculation.
• Example AMM buys:
  • Tx 3CTe5QYM5BXDDuvf…
  • Tx QQMLeYdLFDT9kAtu…

• Pumpswap 0-Block Buy – Mirrors Pumpswap buy transactions immediately for same-block or next-block inclusion.

  • Example transactions:

• CPMM 0-Block Buy – Mirrors Raydium CPMM swap transactions with 0-block optimization.

  • Example transactions:

• Take Profit – Automatically sells when price reaches the configured profit percentage (default: 10%).
• Stop Loss – Protects against losses by selling when price drops below the configured threshold (default: 5%).
• Trailing Stop Loss – Dynamic stop loss that follows the highest price, selling if price drops by the configured percentage from the peak (default: 3%).
• Lifetime-Based Selling – Automatically sells positions after a configured lifetime in seconds (default: 30 seconds).
• Price Monitoring – Continuously monitors token prices at configured intervals (default: 5 seconds) to trigger auto-sell conditions.

• Set CONFIRM_SERVICE to NOZOMI, ZERO_SLOT, or JITO to route tips through external relays (disabled by default).
• The monitor spawns a background task (recent_blockhash_handler) to keep slot info fresh for signing.
• SIGNATURES cache automatically purges after 3 seconds; adjust if copying frequent multi-leg transactions.
• Continuous logging of start-to-submit elapsed time helps track RPC health (e.g., Period from start: 509.438792ms).

• Wallet management UI for swapping target addresses on the fly.
• Quote engine integration with Jupiter for fallback route discovery.
• Persistent metrics sink beyond console (InfluxDB / Prometheus).
• Automated slippage tuning fed by historical fill rates.
