Polygon Agent CLI#

Prerequisites#

• Node.js 22+
• Run via npx: npx @polygonlabs/agent-cli <command>
• Storage: ~/.polygon-agent/ (AES-256-GCM encrypted)

Session Initialization#

Before running any commands, use the Read tool to check ~/.polygon-agent/builder.json:

• If it exists — extract accessKey from the JSON and export as plain shell vars (no $() subshells): bash

  export SEQUENCE_PROJECT_ACCESS_KEY=<accessKey>
  export SEQUENCE_INDEXER_ACCESS_KEY=$SEQUENCE_PROJECT_ACCESS_KEY
  export TRAILS_API_KEY=$SEQUENCE_PROJECT_ACCESS_KEY
  
  

• If it doesn't exist — the user hasn't completed setup yet. Proceed to Phase 1 ( setup) which will create the file.

Environment Variables#

Required#

One key, three names — SEQUENCE_INDEXER_ACCESS_KEY and TRAILS_API_KEY are the same value as SEQUENCE_PROJECT_ACCESS_KEY. Set them all once:

bash

export SEQUENCE_PROJECT_ACCESS_KEY=<access-key-from-setup>
export SEQUENCE_INDEXER_ACCESS_KEY=$SEQUENCE_PROJECT_ACCESS_KEY
export TRAILS_API_KEY=$SEQUENCE_PROJECT_ACCESS_KEY

Optional#

VariableDefaultSEQUENCE_ECOSYSTEM_CONNECTOR_URL``https://agentconnect.polygon.technology/``SEQUENCE_DAPP_ORIGINSame as connector URL originTRAILS_TOKEN_MAP_JSONToken-directory lookupPOLYGON_AGENT_DEBUG_FETCHOff — logs HTTP to ~/.polygon-agent/fetch-debug.log``POLYGON_AGENT_DEBUG_FEEOff — dumps fee options to stderr

Complete Setup Flow#

bash

# Phase 1: Setup (creates EOA + Sequence project, returns access key)
polygon-agent setup --name "MyAgent"
# → save privateKey (not shown again), eoaAddress, accessKey

# Phase 2: Create ecosystem wallet (auto-waits for browser approval)
export SEQUENCE_PROJECT_ACCESS_KEY=<accessKey>
polygon-agent wallet create --usdc-limit 100 --native-limit 5

# Phase 3: Fund wallet
polygon-agent fund
# → reads walletAddress from session, builds Trails widget URL with toAddress=<walletAddress>
# → ALWAYS run this command to get the URL — never construct it manually or hardcode any address
# → send the returned `fundingUrl` to the user; `walletAddress` in the output confirms the recipient

# Phase 4: Verify (SEQUENCE_INDEXER_ACCESS_KEY is the same as your project access key)
export SEQUENCE_INDEXER_ACCESS_KEY=$SEQUENCE_PROJECT_ACCESS_KEY
polygon-agent balances

# Phase 5: Register agent on-chain (ERC-8004, Polygon mainnet)
polygon-agent agent register --name "MyAgent" --broadcast
# → mints ERC-721 NFT, emits agentId in Registered event
# → use agentId for reputation queries and feedback

Key Behaviors#

• Dry-run by default — all write commands require --broadcast to execute
• Smart defaults — --wallet main, --chain polygon, auto-wait on wallet create
• Fee preference — auto-selects USDC over native POL when both available
• fund — reads walletAddress from the wallet session and sets it as toAddress in the Trails widget URL. Always run polygon-agent fund to get the correct URL — never construct it manually or hardcode any address. The returned JSON contains fundingUrl and walletAddress so you can confirm the pre-filled recipient before sharing.
• deposit — picks highest-TVL pool via Trails getEarnPools. If session rejects, re-create wallet with --contract <depositAddress>
• x402-pay — probes endpoint for 402, smart wallet funds builder EOA with exact token amount, EOA signs EIP-3009 payment. Chain auto-detected from 402 response
• send-native --direct — bypasses ValueForwarder contract for direct EOA transfer
• Session permissions — without --usdc-limit etc., session gets bare-bones defaults and may not transact

CRITICAL: Wallet Approval URL#

When wallet create outputs a URL in the url or approvalUrl field, you MUST send the COMPLETE, UNTRUNCATED URL to the user. The URL contains cryptographic parameters (public key, callback token) that are required for session approval. If any part is cut off, the approval will fail.

• Do NOT shorten, summarize, or add ... to the URL
• Do NOT split the URL across multiple messages
• Output the raw URL exactly as returned by the CLI

Callback Modes#

The wallet create command automatically starts a local HTTP server and opens a Cloudflare Quick Tunnel ( *.trycloudflare.com) — no account or token required. The cloudflared binary is auto-downloaded to ~/.polygon-agent/bin/cloudflared on first use if not already installed. The connector UI POSTs the encrypted session back through the tunnel regardless of where the agent is running. The tunnel and server are torn down automatically once the session is received.

Timing: The approvalUrl is only valid while the CLI process is running. Open it immediately and complete wallet approval within the timeout window (default 300s). Never reuse a URL from a previous run — the tunnel is torn down when the CLI exits.

Manual fallback (if cloudflared is unavailable): The CLI omits callbackUrl so the connector UI displays the encrypted blob in the browser. The CLI then prompts:

text

After approving in the browser, the encrypted blob will be shown.
Paste it below and press Enter:
> <paste blob here>

The blob is also saved to /tmp/polygon-session-<rid>.txt for reference. To import later:

bash

polygon-agent wallet import --ciphertext @/tmp/polygon-session-<rid>.txt
