LI.FI Link Parameterization

Use parameters to link to jumper.exchange and pre-determine the user's bridge- & swapping route.

While you're working on integrating our SDK into your dApp, you can send a link with preset parameters of the desired token and desired chain for your users to swap to the right tokens. 
Example: Swap from the user's current chain to MAGIC on Arbitrum.
​https://jumper.exchange/?toChain=arb&toToken=0x539bde0d7dbd336b79148aa742883198bbf60342​
Construction: 
https://jumper.exchange/? 
toChain=arb& 
toToken=0x539bde0d7dbd336b79148aa742883198bbf60342
Similarly: Swap 100 MAGIC from Arbitrum to AAVE on Polygon
​https://jumper.exchange/?fromChain=arb&fromToken=0x539bde0d7dbd336b79148aa742883198bbf60342&toChain=pol&toToken=0xd6df932a45c0f255f85145f286ea0b292b21c90b&fromAmount=100​
Note: Dear devs, you can either use a ChainId(1) or Chain Abbreviation (eth) as listed below :)
