What is Taco

Taco is an onchain trading protocol where the counterparty is a vault owned by its users. Trade perpetual markets with up to 1,000× leverage, zero price impact, and no opening, closing or funding fees. See Markets for what is listed.

Every trade settles against the Vault, an ERC-4626 vault holding USDT that started at zero, with no seed capital. Losses are credited to the Vault; a part of each loss comes back to the trader as TLP, the Vault’s share token, so the people who trade against the Vault are also the people who own it. No market makers, no hidden books: positions, settlements and Vault equity are all on chain.

  • Up to 1,000× leverage, 24/7.
  • No price impact: size never moves the price.
  • No opening, closing or funding fees.
  • Onchain settlement: for every trade and position.
  • Open Vault: part of every loss returns as TLP.
