THORChain is a decentralized exchange protocol designed to swap native assets across different blockchains, such as Bitcoin and Ethereum, without bridges or wrapped tokens. It is permissionless and requires no KYC.
The project began around 2018, led largely by pseudonymous contributors, and launched its multichain mainnet in 2021 after several test phases. It currently supports 13 chains, including Bitcoin, Ethereum, XRP Ledger, BNB Smart Chain, Solana, TRON and Dogecoin, with more planned.
THORChain is an independent blockchain built with the Cosmos SDK and Tendermint consensus. Node operators jointly control vaults on each connected chain using threshold signature schemes (TSS), so no single party can move funds alone.
Trades run through liquidity pools that pair each external asset with RUNE. A Bitcoin to Ethereum swap, for example, routes BTC through RUNE into ETH, and the user receives the native asset on its original chain.

RUNE is the base asset in every liquidity pool, the bond that node operators must post as collateral, and the token used for network fees. Revenue from swap fees is split by set ratios among node operators, liquidity providers and other parts of the system.
Recent reports say RUNE is now fully unlocked, and governance-approved burns have reduced total supply below the original plan. Many wallets and swap interfaces connect to THORChain to offer cross-chain swaps.
Its main draw is swapping native assets without wrapped tokens or handing funds to a central custodian. Years of operation have made it one of the best-known protocols in cross-chain swapping.
On the other hand, it suffered several exploits in 2021 and paused withdrawals from its lending and savings products (THORFi) in 2025. It also faces regulatory scrutiny over its use in laundering hacked funds, and swaps can halt temporarily when connected chains have problems, so technical and regulatory risks deserve attention.
