# KeepStakeBlockedByCollateral (/docs/errors/chain/KeepStakeBlockedByCollateral)

A hotkey swap with keep\_stake=true was refused because the old hotkey still has standing miner registration collateral. keep\_stake leaves stake on the old key while the UID moves, which would strand the bond. Retry with keep\_stake=false so collateral migrates with the UID; on-chain hotkey lineage maps track the rename for blacklist continuity. Or drain the bond through earned emission first.
