# STON.fi

> Cross-chain DeFi, without the chaos

STON.fi is a decentralized exchange and liquidity aggregation protocol. It lets users swap tokens on TON and across multiple blockchains from a self-custodial interface.

STON.fi is a decentralized exchange and liquidity aggregation protocol on the TON blockchain with support for cross-chain swaps. Users swap tokens, provide liquidity to pools, farm rewards, and stake the STON token from a self-custodial interface that needs no account. The interface shows routes, fees, and expected output before a swap is confirmed.

The STON.fi DEX uses automated market maker pools on TON where liquidity providers earn trading fees. Omniston, the liquidity aggregation protocol, collects quotes from decentralized exchanges and market makers and settles cross-chain swaps atomically, so each swap completes in full or is refunded in full. Developers integrate swaps through an SDK, an API, and an embeddable widget.

STON.fi has two products, the STON.fi DEX and Omniston. The STON token is the protocol's utility token and gives governance rights through long-term staking. STON.fi is used by traders, liquidity providers, wallets, and applications that embed swaps.

## Products

- [STON.fi DEX](https://thegrid.id/profiles/ston_fi): STON.fi DEX is an automated market maker exchange on the TON blockchain where users swap tokens, provide liquidity to pools, and farm rewards. Trading fees are set per pool and go to liquidity providers. Users connect a self-custodial wallet to the web app, and developers can embed swaps through an SDK, an API, and a widget. (Decentralised Exchange, Live, Main Product)
- [Omniston](https://thegrid.id/profiles/ston_fi): Omniston is a liquidity aggregation protocol that returns executable quotes for swaps on TON and across blockchains. Traders send a request for quote, and decentralized exchanges and resolvers respond, with the selected resolver supplying destination-side liquidity. Cross-chain swaps settle atomically through hash time-locked contracts, so each swap completes in full or is refunded in full. Integrators add it through an SDK and API and can set their own fee on each swap. (DEX Aggregator, Live)

## Assets

- [STON (STON)](https://thegrid.id/profiles/ston_fi): STON is the utility and governance token of the STON.fi protocol on the TON blockchain. It is used to participate in decentralized governance through long-term staking, which grants users DAO voting power to vote on protocol upgrades and new features. When users stake STON, they receive ARKENSTON tokens that represent voting power, with higher stakes and longer lock periods increasing governance influence. (Utility)
