BSC (BNB Smart Chain)

Native token: BNB

Decimal Differences on BSC

  • USDC and USDT use 18 decimals on BSC, not 6 like on Ethereum. To swap 100 USDC on BSC, use amount=100000000000000000000 (100 * 10^18), not 100000000 (100 * 10^6).

Important

Decimal Differences

Chains where stablecoin decimals differ from Ethereum

  • BSC (56): USDC and USDT are 18 decimals, not 6 like on Ethereum.
  • Rootstock (30): USDC and USDT are 18 decimals, not 6 like on Ethereum.
  • Boba BNB (56288): USDC and USDT are 18 decimals, not 6.
  • Blast (81457): No canonical USDC/USDT. Uses USDB (18 decimals) as the native stablecoin.

Always check the decimals field in the API response to confirm the correct token precision. Using the wrong decimal count will result in sending far more or less value than intended.

Native tokens

How to Use Native Tokens

Native gas token address

Use the following address for the native gas token on any supported chain:

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE

  • This works for ETH on Ethereum/Arbitrum/Base/Optimism, BNB on BSC, POL on Polygon, AVAX on Avalanche, and every other supported chain.
  • Native tokens always use 18 decimals.
  • When swapping native tokens, no ERC-20 approval is needed.
