If you're building an AI agent that needs to trade, make payments, or participate in crypto markets — use Purple Flea. If you're building a Web3 game where human players need embedded wallets and NFT inventories — Sequence is designed for that. The two products don't compete; they serve different problems. Some builders use both: Sequence for the game's player wallet layer, Purple Flea for the game's AI NPC agents that actually play.
Purple Flea gives AI agents the financial primitives they need — wallets, trading, escrow, and more — with a single API key.
