O3Swap is a cross-chain aggregation protocol which draws lots of attention recently. Compared with other DEXes and bridges, O3Swap is pretty cool because it allows swapping token A for token B between different chains. For example, users are able to swap ETH on Ethereum network for BUSD on Binance Smart Chain.

In addition, the staking model of O3Swap is also unique. O3 token is it native token which also given to people who provide liquidity on its platform. However, unlike other yield farming projects, the staking reward cannot be withdrawn directly. Instead, an unlock procedure is required by staking certain token pairs with O3 included either on PancakeSwap or on Uniswap depending on which network they staked. For instance, users should provide liquidity of O3-BUSD pairs on PancakeSwap, and then wait for a period of time for unlock their O3 tokens. This mechanism is designed to prevent from huge selling of O3, and therefore, helps to keep O3 price more stable. Alternatively, for those who dislike the token lock mechanism may consider buying O3 directly via PancakeSwap and stake on PancakeSwap in the form of O3-BUSD LP.

Generally speaking, O3Swap is an amazing project focusing on real cross-chain transactions. We look forward to further development on O3Swap and bringing more benefits for defi users.
