Span Chain Bridge

spookyswap
SpookySwap is the Automated Market Maker (AMM) Decentralized Exchange (DEX) for the Fantom Opera network. Unlike other DEXs, we have invested in building a strong foundation with our BOO tokens as governance tokens, diverse farms, built-in bridges, built-in limit orders and user-centric services.

BurgerSwap
BurgerSwap, which I believe you are also familiar with, was launched in September last year when liquidity mining was hot, and already supports exchange, provides liquidity, community governance and cross-chain functions. The cross-chain supported chains are currently ETH, CoinAffiliate and BSC inter-span, and more transaction pairs are supported.
