What it is
A TypeScript trading bot that posts a post-only limit order on the Kuru MON-USDC order book every Monad block, using a TypeSafe Jev model to decide buy or sell. It dry-runs without a private key.
How it uses Jev
Every block, Jev is asked about the price move over HORIZON_BLOCKS (default 100, ~30 s) and returns buy or sell probabilities. The action with the higher probability determines the side of the post-only limit order placed that block.
Primitives:choice
Technique worth stealing
Keep the hot loop to two RPC round trips: one eth_call for the book and one eth_sendRawTransaction, with receipts and gas estimates off the path.
Try it
cp .env.example .env && bun install && bun run start
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
