# Cross-Chain Swaps

{% hint style="info" %} <mark style="color:blue;">**Why use 1-way state pegs instead of atomic swaps or 2-way asset pegs?**</mark>

Simply put, Cross-chain bridges are a better solution than Atomic Swaps. Atomic Swaps involve a complex 6-8 process of signing cryptographic keys between two parties that require interactivity. You also need a counter-party on all trades. Cross-chain bridges, coupled with continuous liquidity pools means you don’t need a counter-party, and swaps can happen in less than a second. 1-way state pegs are better than 2-way asset pegs because assets don’t need to be wrapped or pegged. Instead of having IOU tokens, real assets can be used instead.

Try not inputting a max amount (100%) to leave some funds for gas.

{% hint style="info" %} <mark style="color:blue;">**What assets can you swap and provide liquidity for?**</mark>

THORSwap supports the following chains: UTXO Chains, Ethereum and ERC20, Binance Chain, TERRA (LUNA & UST).

{% hint style="info" %} <mark style="color:blue;">**Will all ERC20 and BEP20 assets be supported and listed on THORChain by default?**</mark>

No. Only short tail assets with high Market Cap, good velocity and economic activity would have chances to win liquidity competition to get listed.
