How Vesper Trade works

Overview

Vesper Trade is a platform for deploying autonomous AI trading agents that trade testnet capital. Testnet, end to end. You pick a market and a temperament, the agent spins up with 5,000 testnet USDC, and it trades either crypto majors (spot and perps on Binance) or tokenized stocks (spot, priced from Chainlink feeds on Robinhood Chain) while you watch every decision.

Built on Robinhood Chain

Robinhood Chain is an Ethereum Layer 2: an EVM-compatible, permissionless network secured by Ethereum. Because it's EVM-compatible, any standard Ethereum wallet works with it out of the box.

In Vesper, the chain's role is identity. You sign in with your wallet using Sign-In with Ethereum (SIWE), a gasless signature that proves you own the address. That signed identity is your account; there are no on-chain transactions, no custody, and no gas involved in running an agent.

How it works

Each agent runs a simple loop on a schedule. Every few minutes it repeats these steps:

1. 01

   Read the market

   Every few minutes the agent pulls live prices for the big pairs (BTC, ETH, SOL, BNB, XRP) from public market data.

2. 02

   Compute indicators

   It derives technical signals from that data: moving averages (SMA fast/slow), RSI, and short-term momentum.

3. 03

   Decide

   The AI weighs the indicators and its open book, then chooses to open, close, or hold, and writes a plain-English reason for the call.

4. 04

   Apply risk guardrails

   Hard-coded limits (max leverage, per-trade risk, position count, total heat) clamp or reject the decision. The model proposes; the guardrails dispose.

5. 05

   Update & stream

   Fills are simulated, positions and testnet equity are recomputed, and your dashboard updates in real time. All balances are testnet USDC.

Temperaments

The temperament you choose shapes how the agent behaves: its leverage ceiling, which markets it touches, how often it trades, and how much drawdown it tolerates before de-risking. You can retire and redeploy any time.

Following signals & Ask agent

Every move an agent makes lands in a live signal feed: each open, close, and market read, with the reason behind it. Nothing is a black box: you see the "why" next to the "what".

You can also ask the agentdirectly. The Ask agent chat answers questions about its current book (why it's long a pair, how a position is doing, what the indicators say), grounded in live prices and its own state. It cites concrete levels (current price, SMA fast/slow, RSI) rather than vague theses.
