The agent - Portir

The Portir agent is one long-running process built with BNB Agent Studio (bag). It runs at https://agent.portir.xyz.

What it automates

Loop	Every	Does
Executor	15 min	Runs due plans and sell rules: Guard, news check, pull funds, buy, deliver, record
Loan Guard	5 min	Reads guarded Venus positions and rescues those past their trigger
Telegram	on each outcome	Sends linked users a message for every recorded run and rescue

Three faces

Face	Endpoint	For
MCP	`/mcp`	Claude or any MCP client: twelve read-only tools
x402	`/x402`	Natural-language questions, answered with the same tools. Free today (`price_usd = 0`)
A2A	agent card at `/.well-known/agent-card.json`	Other agents

Ask the agent, right on the Plans page

Two brains, one rule

The executor itself never uses an LLM: buys are decided by the Guard, which is code. A language model is used only for two things, and neither can move money:

Chat (“Ask the agent” in the app, and /x402).
The news check, which can only hold a buy back with a reason.

In production both run on Groq (openai/gpt-oss-120b) through Agent Studio’s OpenAI-compatible model provider. The operator pays for it, not you. If no model answers, plans keep running.

Its hands: Binance Agentic Wallet

On mainnet the agent trades through a Binance Agentic Wallet: an MPC wallet with no private key on the server, whose daily cap, allowed tokens and high-risk confirmations are set by its owner in the Binance App and enforced by Binance. On testnet it settles on TestExchange with a keeper-signed quote. See Testnet and mainnet.

Hosting

The agent runs in Docker on a VPS behind Caddy (HTTPS), with a fixed IP for the B402 allowlist.
