Following its recent expansion to Binance Smart Chain, 1inch has launched a powerful Swap API tailored for BSC users. This API combines lightning-fast transaction speeds with optimal swap rates, leveraging advanced aggregation technology to streamline decentralized trading.
How 1inch’s BSC Swap API Works
1inch’s API is an aggregator solution that:
- Scans multiple protocols to find the most efficient token-swap paths.
- Splits transactions across different liquidity sources (even within a single protocol) for better rates.
- Generates call data for seamless blockchain execution—users can execute swaps in a single smart contract call.
Key Features:
✅ Median response time under 400ms
✅ Supports bots, dApps, and fee-earning integrations
✅ User-friendly code implementation (example below):
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);Supported Protocols on BSC
