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):

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.

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:

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

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

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
# → 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

Commands Reference

Setup

polygon-agent fund [--wallet <n>] [--token <addr>]
polygon-agent x402-pay --url <url> --wallet <n> [--method GET] [--body <str>] [--header Key:Value]

Agent (ERC-8004)

bash

polygon-agent agent register --name <n> [--agent-uri <uri>] [--metadata <k=v,k=v>] [--broadcast]
polygon-agent agent wallet --agent-id <id>
polygon-agent agent metadata --agent-id <id> --key <key>
polygon-agent agent reputation --agent-id <id> [--tag1 <tag>]
polygon-agent agent reviews --agent-id <id>
polygon-agent agent feedback --agent-id <id> --value <score> [--tag1 <t>] [--tag2 <t>] [--endpoint <e>] [--broadcast]

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

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

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`
