Setting toAmount

If you want to buy something worth a certain amount, the best method is to overestimate by more than the expected slippage. We have a method on the SDK to estimate the required fromAmount you need to get a toAmount on the destination chain. It uses coingecko prices to approximate a number.

Get a fromAmount based on fromToken, toToken and toAmount.

Example usage:

const ETH = squid.getTokenData(
  "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE",
  "1"
);

const USDC = squid.getTokenData(
  "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
  "1"
);

const usdcToEth = await squid.getFromAmount({
  fromToken: USDC,
  toAmount: "1",
  toToken: ETH
}); // expected: ~1600

const ethToUsdc = await squid.getFromAmount({
  fromToken: ETH,
  toAmount: "200",
  toToken: USDC
}); // expected: ~0.12...

// you can also specify slippage percentage (default is 1.5%)
const usdcToEth3 = await squid.getFromAmount({
  fromToken: USDC,
  toAmount: "1",
  toToken: ETH,
  slippagePercentage: 3
}); // expected: ~1648
