Euler Base Vault Bot

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

• deposit USDC into the AlphaGrowth Euler vault on Base
• check AlphaGrowth vault position and APY
• compound Euler vault rewards
• withdraw from AlphaGrowth Base vault

On Invoke

Immediately run a dry-run vault position check without asking. Do not present a menu of modes. Execute:

cd ~/.config/seren/skills/euler-base-vault-bot && 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 (deposit, compound, withdraw, live mode). If the user explicitly requests a specific action in their invocation message, run that action instead.

Workflow Summary

1. probe_rpc uses connector.rpc_base.post
2. read_vault_state uses connector.rpc_base.post
3. read_position uses connector.rpc_base.post
4. build_transactions uses transform.create_plan
5. estimate_gas uses connector.rpc_base.post
6. live_guard uses transform.guard_live_execution
7. execute_transactions uses connector.rpc_base.post

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 vault withdrawal path. If the user did not identify whether the request is for a deposit, compound cycle, or full withdrawal, ask only the minimum clarifying question needed to identify it.

Pre-Trade Checklist

Before any live vault action:

1. Verify SEREN_API_KEY is loaded and the rpc_base connector is reachable.
2. Verify the configured wallet_mode dependency is present: WALLET_PRIVATE_KEY for local signing or LEDGER_ADDRESS for ledger mode.
3. Verify the requested deposit, compound, or withdraw amount is valid for the current position.
4. If any credential, signer dependency, or Base RPC probe fails, stop here and fail closed instead of building live transactions.

Dependency Validation

Dependency validation is required before live execution. Verify SEREN_API_KEY, the rpc_base connector, and the selected signer dependency are loaded and reachable. If credentials are missing, the connector is unsupported, or the signer dependency is missing, the runtime must stop with an error instead of executing vault actions.

Live Safety Opt-In

Default mode is dry-run. Live execution requires both:

• inputs.live_mode=true with dry_run=false in config
• python3 scripts/agent.py --config config.json --allow-live

The --allow-live flag is a startup-only opt-in for that process. It is not a per-transaction approval prompt.

Emergency Exit Path

To stop trading immediately, run python3 scripts/agent.py --config config.json --emergency-exit. The emergency-exit path prepares the full withdrawal workflow and marks the current vault position for liquidation without asking for an extra live confirmation.

API Key Setup

Before running this skill, check for an existing Seren API key in this order:

1. Seren Desktop auth — if the skill is running inside Seren Desktop, the runtime injects API_KEY automatically. Check: echo $API_KEY. If set, no further action is needed.
2. Existing .env file — check if SEREN_API_KEY is already set in the skill's .env file. If set, no further action is needed.
3. Shell environment — check if SEREN_API_KEY is exported in the current shell. If set, no further action is needed.

Only if none of the above are set, register a new agent account:

curl -sS -X POST "https://api.serendb.com/auth/agent" \
  -H "Content-Type: application/json" \
  -d '{"name":"euler-base-vault-bot"}'

Extract the API key from the response at .data.agent.api_key — this key is shown only once. Write it to the skill's .env file:

SEREN_API_KEY=<the-returned-key>

Verify:

curl -sS "https://api.serendb.com/auth/me" \
  -H "Authorization: Bearer $SEREN_API_KEY"

Do not create a new account if a key already exists. Creating a duplicate account results in a $0-balance key that overrides the user's funded account.

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.

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:

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.

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:

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:

publisher: seren-cron
path:      /jobs
method:    POST
body: {
  "name":            "euler-vault-compound-live",
  "url":             "http://localhost:8080/run",
  "method":          "POST",
  "cron_expression": "0 */12 * * *",
  "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:

publisher: seren-cron, path: /jobs, method: GET

Pause:

publisher: seren-cron, path: /jobs/{job_id}/pause, method: POST

Resume:

publisher: seren-cron, path: /jobs/{job_id}/resume, method: POST

Stop permanently:

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:

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.
