Polygon Agent CLI
Prerequisites
-
Node.js 20+
-
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 $() subshells): export SEQUENCE_PROJECT_ACCESS_KEY=<accessKey> export SEQUENCE_INDEXER_ACCESS_KEY=$SEQUENCE_PROJECT_ACCESS_KEY export TRAILS_API_KEY=$SEQUENCE_PROJECT_ACCESS_KEY
-
If it doesn't exist — the user hasn't completed setup yet. Proceed to Phase 1 (setup ) which will create the file.
Architecture
Wallet Created by Purpose Fund?
EOA setup
Auth with Sequence Builder NO
Ecosystem Wallet wallet create
Primary spending wallet YES
Environment Variables
Required
Variable When
SEQUENCE_PROJECT_ACCESS_KEY
Wallet creation, swaps, balance checks, Trails
One key, three names — SEQUENCE_INDEXER_ACCESS_KEY and TRAILS_API_KEY are the same value as SEQUENCE_PROJECT_ACCESS_KEY . Set them all once:
export SEQUENCE_PROJECT_ACCESS_KEY=<access-key-from-setup> export SEQUENCE_INDEXER_ACCESS_KEY=$SEQUENCE_PROJECT_ACCESS_KEY export TRAILS_API_KEY=$SEQUENCE_PROJECT_ACCESS_KEY
Optional
Variable Default
SEQUENCE_ECOSYSTEM_CONNECTOR_URL
https://agentconnect.polygon.technology/
SEQUENCE_DAPP_ORIGIN
Same as connector URL origin
TRAILS_TOKEN_MAP_JSON
Token-directory lookup
POLYGON_AGENT_DEBUG_FETCH
Off — logs HTTP to ~/.polygon-agent/fetch-debug.log
POLYGON_AGENT_DEBUG_FEE
Off — dumps fee options to stderr
Complete Setup Flow
Phase 1: Setup (creates EOA + Sequence project, returns access key)
polygon-agent setup --name "MyAgent"
→ save privateKey (not shown again), eoaAddress, accessKey
Phase 2: Create ecosystem wallet (auto-waits for browser approval)
export SEQUENCE_PROJECT_ACCESS_KEY=<accessKey> polygon-agent wallet create --usdc-limit 100 --native-limit 5
→ IMPORTANT: The command outputs an approvalUrl. You MUST send the COMPLETE,
UNTRUNCATED URL to the user and wait for them to open it in a browser and approve.
Do NOT proceed to the next step until the user confirms approval (or the CLI
automatically detects the callback). The wallet address is only available after approval.
Phase 3: Fund wallet
polygon-agent fund
→ reads walletAddress from session, builds Trails widget URL with toAddress=<walletAddress>
→ ALWAYS run this command to get the URL — never construct it manually or hardcode any address
→ send the returned fundingUrl to the user; walletAddress in the output confirms the recipient
Phase 4: Verify (SEQUENCE_INDEXER_ACCESS_KEY is the same as your project access key)
export SEQUENCE_INDEXER_ACCESS_KEY=$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 . Important: --usdc-limit restricts the USDC session to transfer calls only, which blocks the approve call that deposit requires. To use deposit , omit --usdc-limit and instead whitelist USDC via --contract 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 (unrestricted). Also add the protocol pool address via --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:
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:
polygon-agent wallet import --ciphertext @/tmp/polygon-session-<rid>.txt
Troubleshooting
Issue Fix
Builder configured already
Add --force
Missing SEQUENCE_PROJECT_ACCESS_KEY
Run setup first
Missing wallet
wallet list , re-run wallet create
Session expired
Re-run wallet create (24h expiry)
Fee option errors
Set POLYGON_AGENT_DEBUG_FEE=1 , ensure wallet has funds
Timed out waiting for callback
Add --timeout 600
callbackMode: manual (no tunnel) cloudflared unavailable — paste blob from browser when prompted; blob saved to /tmp/polygon-session-<rid>.txt
404 on *.trycloudflare.com
CLI timed out and tunnel is gone — re-run wallet create , open the new approvalUrl immediately
"Auto-send failed" in browser Copy the ciphertext shown below that message; run wallet import --ciphertext '<blob>'
Deposit session rejected --usdc-limit blocks approve calls — omit it and use --contract 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 --contract <depositAddress> instead
Wrong recipient in Trails widget Run polygon-agent fund (do not construct the URL manually); walletAddress in the output confirms the pre-filled toAddress
