What does wrapping BNB do?

Wrapping converts your native BNB into an ERC-20 token (WBNB) at a 1:1 ratio. Many DeFi protocols and DEX routers only accept ERC-20 tokens, so they require the wrapped form.

Can I unwrap only part of my balance?

Yes. Unlike some wrapped assets, WBNB (WETH9) supports partial unwrapping, so you can convert back any amount up to your wrapped balance.

Is the conversion always 1:1?

Yes. Wrapping and unwrapping are always 1:1. You only pay the flat Smithii fee plus the network gas for the transaction.

Wrap and Unwrap BNB Instantly on BNB Chain

A wrapped native token like WBNB (WETH, WBNB, WAVAX, WPOL and so on) is an ERC-20 that represents the chain's native coin at a 1:1 ratio. On BNB Chain, many DeFi protocols and smart contracts require the ERC-20 wrapped form (WBNB) instead of the raw BNB. This tool converts between them without any coding.

Wrapping deposits your BNB into the canonical WBNB contract and mints the same amount of the wrapped token. Unwrapping withdraws it back to BNB. Unlike some chains, EVM wrapping supports partial amounts, so you can unwrap exactly what you need.

When Do You Need WBNB?

You typically need WBNB when providing liquidity, swapping on a DEX, or interacting with lending and staking protocols on BNB Chain that only accept ERC-20 tokens. If you're adding liquidity with a BNB pair, most routers work with WBNB under the hood. This wrapper handles the conversion for you in a couple of clicks.
