What is Native vs bridged token?

A distinction between an asset issued directly on a blockchain and a representation brought from another chain through a bridge.

Why it matters on your return

Native and bridged versions of the same asset can trade at different prices and carry different risk, and swapping between them is a disposal under the exchange position. Bridged tokens that lose their backing become worthless on their own, separately from the native asset.

Example

You hold native USDC on Base and bridged USDC.e from an older bridge. Swapping USDC.e for USDC is a disposal of the USDC.e at fair market value, usually a gain or loss of a few cents per token.

Is swapping a bridged token for the native version taxable?

Under the common position, yes, because they are different tokens from different issuers even if they represent the same underlying asset.
