Cosmos unbonding and IBC transfers

Cosmos chains impose an unbonding period (often 21 days) before staked tokens can move, and IBC lets tokens move between Cosmos chains.

What is Cosmos unbonding and IBC transfers?

Cosmos chains impose an unbonding period (often 21 days) before staked tokens can move, and IBC lets tokens move between Cosmos chains.

Why it matters on your return

Rewards on Cosmos chains are claimable continuously and are income when claimed or claimable. Unbonding is a transfer of your own tokens; nothing is taxed when the period ends. IBC transfers of the same asset between chains are transfers, though a token that arrives as a different denomination should be documented.

Example

You unstake 500 ATOM and wait 21 days. Nothing is taxed. You then send the ATOM over IBC to Osmosis: a transfer, with basis carried. Swapping on Osmosis is a disposal.

Is unbonding taxable?

No. It moves your own tokens from staked to liquid. Income arises on rewards; disposals arise on swaps.
