Curve-gauge-yield-trader — Автоматизированный трейдинг доходностью в DeFi

--- name: curve-gauge-yield-trader description: "Multi-chain Curve gauge yield trading skill with paper-first defaults. Supports local wallet generation or Ledger signer mode for live execution." --- # Curve Gauge Yield Trader ## For Claude: How to Use This Skill Skill instructions are preloaded in context when this skill is active. Do not perform filesystem searches or tool-driven exploration to rediscover them; use the guidance below directly. ## When to Use - find the best curve gauge rewards - paper trade curve gauge liquidity - trade live on curve gauges ## On Invoke **Immediately run a dry-run gauge scan and trade simulation without asking.** Do not present a menu of modes. Execute: ```bash cd ~/.config/seren/skills/curve-gauge-yield-trader && source .venv/bin/activate && python3 scripts/agent.py --config config.json ``` Display the full dry-run results to the user. Only after results are displayed, present available next steps (live mode). If the user explicitly requests a specific mode in their invocation message, run that mode instead. ## Workflow Summary 1. `fetch_top_gauges` uses `connector.curve_api.get` (`/getGauges`) 2. `choose_trade` uses `transform.select_best_gauge` 3. `signer_setup` uses `transform.setup_signer` 4. `rpc_discovery` resolves chain RPC publisher from gateway catalog (`GET /publishers`) 5. `preflight` builds and estimates local EVM transactions via chain RPC (no cloud signer) 6. `live_guard` uses `transform.guard_live_execution` 7. `execute_liquidity_trade` signs locally and submits with `eth_sendRawTransaction` ## Funding and Safety - Default mode is dry-run. - Live transactions require both: - `inputs.live_mode = true` in config - `--yes-live` on the CLI - Live mode uses real funds. Only fund what you can afford to lose. - Each run resolves the RPC publisher from the live Seren publisher catalog (`GET /publishers`) and performs an explicit probe before preflight/trade. - If probe fails, execution stops early with a clear unsupported-chain/RPC error. - Optional override: set `rpc_publishers` in config (`{ "ethereum": "<slug>" }`) to force a specific publisher slug per chain. - Transactions are prepared and signed locally. - `wallet_mode=local`: agent signs with local private key. - `wallet_mode=ledger`: preflight creates unsigned txs; you provide signed raw txs in `evm_execution.ledger.signed_raw_transactions` for broadcast. ## Disclaimer This skill can trade real money. Use at your own risk. Past performance does not guarantee future results. - DeFi carries smart-contract, oracle, liquidity, and slippage risks. - RPC/provider outages or stale data can cause failed or unfavorable execution. - You are responsible for wallet security, transaction approvals, and chain/network selection. - Start in dry-run, test with small live size, and scale only after repeated stable runs. ## Wallet Modes - `wallet_mode=local`: generate a local wallet with `--init-wallet`, then fund that address. - `wallet_mode=ledger`: provide Ledger address and use preflight output to sign externally. ## Local Execution Config - Default strategy is `evm_execution.strategy = "gauge_stake_lp"`. - Requires `lp_token_address` and `lp_amount_wei` if they cannot be derived from market data. - Optional `gauge_address` override. - For fully custom calls, use `evm_execution.strategy = "custom_tx"` and set: - `evm_execution.custom_tx.to` - `evm_execution.custom_tx.data` - `evm_execution.custom_tx.value_wei` - Gas behavior is controlled with: - `evm_execution.tx.gas_price_multiplier` - `evm_execution.tx.gas_limit_multiplier` - `evm_execution.tx.fallback_gas_limit` ## Trade Execution Contract When the user says `sell`, `close`, `exit`, `unwind`, or `flatten`, treat that as an immediate operator instruction to stop trading and prepare the LP or gauge withdrawal path. If the user did not identify which chain or signer should be used, ask only the minimum clarifying question needed to identify it. ## Pre-Trade Checklist Before any live execution: 1. Verify `SEREN_API_KEY` is loaded and the configured RPC publisher is reachable. 2. Verify signer dependencies are installed and loaded: `eth-account` for local signing, or a valid ledger address for ledger mode. 3. Verify `eth-abi` and `eth-utils` are installed when local EVM encoding is required. 4. If any credential, library, signer, or RPC probe fails, stop here and fail closed instead of submitting transactions. ## Dependency Validation Dependency validation is required before live trading. Verify `SEREN_API_KEY`, the resolved RPC publisher, `eth-account`, `eth-abi`, `eth-utils`, and the selected signer inputs are installed and loaded. If a credential is missing, the RPC path is unsupported, or a required library is not installed, the runtime must stop with an error instead of submitting transactions. ## Emergency Exit Path To stop trading immediately, run `python scripts/agent.py --config config.json --unwind-all`. The unwind-all path syncs the tracked LP and gauge position, marks the position for liquidation, and returns the exact onchain addresses needed to unwind without placing a new entry order. ## Quick Start 1. Create/get your `SEREN_API_KEY` by following [https://docs.serendb.com/skills.md](https://docs.serendb.com/skills.md), then set it in your environment (for example: `export SEREN_API_KEY=...`). 2. Copy `config.example.json` to `config.json`. 3. Install dependencies: - `pip install -r requirements.txt` 4. Generate local wallet (optional): - `python scripts/agent.py --init-wallet --wallet-path state/wallet.local.json` 5. Dry-run preflight: - `python scripts/agent.py --config config.json` 6. Live mode (only after funding and signer validation): - set `inputs.live_mode=true` in config - `python scripts/agent.py --config config.json --yes-live` ## Seren-Cron Integration Use `seren-cron` to run this skill on a schedule — no terminal windows to keep open, no daemons, no permanent computer changes required. Seren-cron is a cloud scheduler that calls your local trigger server on a cron schedule. Each scheduled run executes one full cycle: sync positions, fetch top gauges, build local preflight txs, and execute if live mode is enabled and `--yes-live` is set on the server process. **Requirements:** Seren Desktop login or a valid `SEREN_API_KEY`. ### Step 1 — Check seren-cron is available Before scheduling, verify the publisher is reachable using `mcp__seren__call_publisher`: ```text publisher: seren-cron path: /health method: GET ``` If this call fails, **stop here** and tell the user: > "The seren-cron service could not be reached. Please send this error to <hello@serendb.com> for support." ### Step 2 — Review active cron jobs (always do this first) **Always check for existing scheduled jobs before creating a new one.** A user may have forgotten a live job is already running. ```text publisher: seren-cron path: /jobs method: GET ``` If jobs for this skill already exist, show them to the user and ask: > "You have [N] active cron job(s) for this skill. Would you like to: > > 1. Keep them running (recommended if intentional) > 2. Stop all and create a new schedule > 3. Cancel" **Do not create a duplicate cron job without explicit user confirmation.** ### Step 3 — Start the local trigger server Start the webhook server that seren-cron will call on each scheduled tick: ```bash SEREN_API_KEY="$SEREN_API_KEY" python3 scripts/run_agent_server.py --config config.json --port 8080 ``` This process runs in your terminal session. When you close the terminal, it stops — **that is expected and correct**. Seren-cron handles the scheduling; your local server handles execution. ### Step 4 — Create the cron schedule With the server running, create the scheduled job: ```text publisher: seren-cron path: /jobs method: POST body: { "name": "curve-gauge-yield-trader-live", "url": "http://localhost:8080/run", "method": "POST", "cron_expression": "*/30 * * * *", "timezone": "UTC", "enabled": true, "timeout_seconds": 60 } ``` Save the returned `job_id` — you need it to pause, resume, or delete the job later. ### Step 5 — Manage the schedule **List all active jobs:** ```text publisher: seren-cron, path: /jobs, method: GET ``` **Pause:** ```text publisher: seren-cron, path: /jobs/{job_id}/pause, method: POST ``` **Resume:** ```text publisher: seren-cron, path: /jobs/{job_id}/resume, method: POST ``` **Stop permanently:** ```text publisher: seren-cron, path: /jobs/{job_id}, method: DELETE ``` ### Insufficient Funds Guard If a live trade or cycle fails because the trading balance or SerenBucks balance is too low to execute, **immediately pause the cron job**: ```text publisher: seren-cron, path: /jobs/{job_id}/pause, method: POST ``` Then tell the user: > "Automated trading has been paused: insufficient funds detected. Please top up your balance before resuming the schedule." Never allow the cron to keep firing when there are no funds available to trade.
