Olai

An analyst agent for one Binance sub-account. It buys the data it needs a cent at a time from its own Binance wallet, trades only inside a rulebook you write, and keeps a receipt for both.

What a call costs

The cent.

Olai pays for market intelligence per call from a Binance Agentic Wallet over x402, no subscriptions, no API keys to hand out, and every payment settles on BNB Smart Chain with a hash it keeps.

A desk that runs one of these pays for the data it actually used that day, not for a subscription it might not open.

Two of Olai’s own cents, settled on BNB Smart Chain:

The rulebook.

Enforced in code before every payment and every order. The model never holds the controls.

Every cent, every rule verdict, every order, hash-chained. Edit a line and the chain breaks.

The payment is real USDT on BNB Smart Chain, the order filled on the Binance spot testnet.

One control the owner always holds

The kill switch.

One click refuses every order and every payment until the owner resumes, mirrored by Binance’s own emergency stop on the sub-account.

It refuses everything that comes after the click; an order already sent to the exchange is not recalled.

What it runs on

Built on Binance Agent OS.

Agentic Wallet

Olai previews the price and signs each payment through the wallet CLI, under the wallet's own daily limit, two real cents settled on BNB Smart Chain.

x402 and the Bazaar

It searches the public B402 catalogue for a listing under its per-call cap, then answers the merchant's 402 on BNB Smart Chain.

The exchange API on an isolated sub-account

Ticker, book, candles, balances and spot orders, with no withdrawal permission, proven on the spot testnet; a live sub-account needs a trade-only key.

The Skills Hub

Not called at runtime. The wallet skill's documentation is what the wallet wrapper was built from.

held: Binance admits only listed agents today

The other door to the same reads and orders. Olai's client is coded and tested, and stays shut until the allowlist opens.
