1inch’s swap API for Binance Smart Chain

Following a recent integration with BSC, 1inch released an API for swaps in the network.

1inch’s swap API for Binance Smart Chain (BSC) is a cutting-edge aggregating solution, offering the chain’s users high transaction speed and the best swap rates on the market.

The API finds the most efficient token swap paths, splitting swaps between different protocols and even different market depts within one protocol. It also builds call data to be sent to the blockchain.

Basically, in one smart contract invocation, discovered paths are transformed into call data, enabling a user to immediately do a swap at the best rate.

One of the API’s main advantages is its extremely short median response time — less than 400ms.

The API can easily be integrated with any dApp or a bot, and integrators can collect fees from users’ swaps.

In addition, the API is very easy to use:

const bnb = ‘0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE’;
const busd = ‘0xe9e7cea3dedca5984780bafc599bd69add087d56’;
const response = await fetch(
`https://api.1inch.exchange/v3.0/56/quote?fromTokenAddress=${bnb}&toTokenAddress=${busd}&amount=1000000000000000000`
);
const quote = await response.json();
console.log(‘Quote: , quote);
