Submit an instant swap with an exact input amount and an optional minimum output for slippage control.

Signature

function swapExactAmountIn(
  client: Client<Signer>,
  parameters: {
    sender: Address
    route: SwapRoute
    input: Coin
    minimumOutput?: string
  },
): Promise<{ hash: Uint8Array } & TxData>

Example

import { createSignerClient, createTransport, testnet, PrivateKeySigner } from "@left-curve/sdk"
import type { Address } from "@left-curve/sdk"
 
const client = createSignerClient({
  chain: testnet,
  transport: createTransport(),
  signer: PrivateKeySigner.fromMnemonic(process.env.DANGO_MNEMONIC!),
})
const sender: Address = "0x1234567890abcdef1234567890abcdef12345678"
 
await client.swapExactAmountIn({
  sender,
  input: { denom: "dango", amount: "1000000000" },
  route: [{ baseDenom: "dango", quoteDenom: "bridge/usdc" }],
  minimumOutput: "490000000",
})
