Twofold is a liquidity protocol on Robinhood Chain (chain id 4663). It runs Uniswap's DualPool contracts, a Uniswap v4 hook design in which the idle side of a liquidity pool is deposited into an ERC-4626 lending vault while the pool remains open for swaps. A liquidity provider in a Twofold pool earns swap fees from the pool and lending yield from the vault on the same deposit.

The protocol deploys Uniswap's DualPoolHook and AllowlistedFactory without modification; the deployed bytecode matches the audited upstream source. Twofold adds a controller, a pool registry, a vault allowlist and a staking vault around those contracts. As of September 2026 the registry lists 24 pools, each pairing the USDG stablecoin against another asset on Robinhood Chain: WETH, TWO, and tokenized equities and funds such as SPY, QQQ, NVDA, AAPL, TSLA, GOOGL, MSFT, META and AMZN. The USDG leg of every pool is routed to a Steakhouse USDG vault built on Morpho Vaults V2. USDG is the only asset on the chain with an eligible vault, so the non-USDG side of each pool earns swap fees only.

TWO is the protocol's token, an ERC-20 with a fixed supply of 1,000,000,000 and no transfer tax. Its contract ownership was renounced at deployment. TWO has two functions: holders can stake it in the StakingVault, which streams rewards to stakers over time, and staked TWO can be wrapped to vTWO for use in PoolVoting, an on-chain signaling contract where holders vote on operator proposals with a minimum voting window of one day. The TWO/WETH genesis liquidity position is held in a locker contract with no withdrawal function.

Twofold provides a web interface at twofold.fi, a Model Context Protocol server for agent access to pools, staking and swaps, and a mobile client in development. The contracts and MCP server are published on GitHub under the twofoldfi organization.
