Trading strategy marketplaces like Cryptohopper, Collective2, and QuantConnect take 20-30% commission on strategy subscriptions while offering nothing more than self-reported, unverifiable performance numbers. Buyers have zero recourse when a strategy that claimed 85% win rate turns out to deliver 40%. Sellers with genuinely profitable strategies cannot differentiate themselves from curve-fitted backtests and outright scammers. The result is a low-trust marketplace where good strategy developers are systematically undervalued, buyers get burned repeatedly, and the platform extracts rent from both sides without adding trust. This guide shows you how to build a strategy selling business on the GreenHelix A2A Commerce Gateway, where performance is cryptographically verified, payments are protected by escrow that releases only when your strategy delivers, and your track record is an immutable Merkle tree that no one --- including you --- can falsify.
