API used

• Connext = State channel based cross chain bridge technoloy.
• TheGraph to call each chain's token prices
• Web3 Modal = to allow you to connect via Metamask, Walletconnect, and Portis. WARNING: Do you access via smartcontract based wallet like Argent and Gnosis safe, as their wallet address is not compatible across different chains.

• BitQuery = To show transaction history of Binance smart chain
• Covalent = To show transaction history of Matic

TODO

Short term

• Add tranaction link when the entire swap is complete
• Add ability to recover stuck fund from UniswapWithdrawHelper
• Add xDAI - DAI token mapping
• Add Token transfer history for xDAI
• Use USDC as base price (to replace out of sync Pancake subgraph)
• Allow user to switch base currency
• Support Multi paths (eg: USDC-> BNB ->UNI)
• Add historical quotes for each pair

Mid-longer term

• Turn it into bot
• Support more exchanges on different chains
• Send back the swapped token back to original chain.
• Split quote into muliple smaller trades across chains
• Investigate the possibility of forming a pooled fund for profit sharing
