Delay Replay Filter

The problem

Most Solana wallets show high raw win rates that vanish when accounting for execution lag and slippage. Developers building copy-trade bots often waste capital on targets that are only profitable for the first few seconds of a pump.

What it does

• Analyzes the last 20 completed round-trips for any public Solana wallet.
• Calculates PnL using realistic 30s, 1m, and 5m entry delays.
• Applies a mandatory 1% cost model to both entry and exit orders.
• Flags wallets as copyable only if 1-minute delayed PnL remains positive over at least 3 trades.
• Operates on a fail-closed principle, returning false if data is missing or RPCs fail.

Frameworks & tools

Python 3, Solana JSON-RPC, Requests.

Why this beats prompting it yourself

Standard LLM prompts struggle to maintain strict mathematical constraints across multiple time-delayed scenarios. This skill enforces a hard-coded scoring logic and cost model that prevents the agent from hallucinating "lucky" fills or ignoring the impact of execution latency.

Use cases

• Vetting potential wallet addresses for copy-trading strategies.
• Building a safety gate for automated trading systems.
• Comparing raw on-chain performance against realistic lag-adjusted returns.
• Filtering out "alpha" that relies entirely on mev-bots or sub-second execution.

Known limitations

Limited to the last 20 completed round-trips. Does not support live transaction execution or private key handling. Requires a public Solana RPC endpoint.
