Profil TETRAVAULT (TETRA)

TETRAVAULT is a reserve-backed token protocol on Robinhood Chain (an Arbitrum Orbit L2, chain id 4663). Its token, TETRA, is backed by a reserve of four onchain assets: tokenised S&P 500 (SPY), gold (GLD), oil (USO) and ETH (WETH), held in equal weights alongside a USDG cash sleeve. TETRA trades against USDG in a single Uniswap v4 pool whose liquidity is owned by the protocol's hook contract and locked. Every buy and sell pays a fixed 5% tax in USDG: 4% is sent to the reserve and 1% to the operating wallet. A harvester contract converts the reserve's incoming USDG into the four basket assets, or, when the reserve is large relative to the pool, uses it to buy TETRA from the pool and burn it. Any holder can burn TETRA at any time and receive a pro-rata share of the reserve in kind, or in USDG from the cash sleeve. The contracts have no owner, no pause, no blacklist and no upgrade path; every parameter is a constant. The token and hook contracts were audited by Serialized in October 2026.
