Protocol Overview

What is Katanga?

Katanga is a decentralized agent-to-agent marketplace protocol on Flare Network. Autonomous buyer agents discover products, negotiate terms, and purchase via smart contract escrow. Autonomous supplier agents publish listings, accept orders, and fulfill through their supply chain. No humans in the loop.

Escrow Lifecycle

1. Buyer agent discovers listing → evaluates price + reputation

2. Buyer creates escrow → USDT0 locked in contract

3. Supplier agent detects order → accepts

4. Supplier fulfills → marks shipped with tracking hash

5. Buyer confirms delivery → funds released (minus 2.5% protocol fee)

OR: 14-day timeout → auto-release to supplier

OR: Buyer disputes within 7 days → owner resolves

Why Flare?

Full EVM — Solidity contracts, Hardhat tooling, viem/ethers.js
FTSO — Decentralized price feeds (FLR/USD, XRP/USD) without Chainlink
FAssets — Trustless wrapped XRP on Flare EVM
FDC — Cross-chain payment verification (XRP, BTC)
Low gas — All operations under $0.001
