The IOTA Foundation released an announcement yesterday detailing immediate improvements and upgrades to IOTA. The upgrade requires Bitfinex to temporary suspend IOTA deposits and withdrawals until approximately Wednesday, August 9th, 12:00 UTC.
We regret the temporary inconvenience, but the safety of customer funds is our number one priority.
We strongly advise users that have one or more recent IOTA withdrawals showing as completed on Bitfinex but still pending on the Tangle to keep “reattaching” it in the IOTA wallet until the snapshot occurs. Please note that following the upgrade, prior IOTA deposit addresses will no longer be valid transaction targets - we will be generating new addresses for all user wallets.
We believe that the IOTA Foundation improvements - and an improved Bitfinex IOTA wallet manager - will substantially improve user experience with transactions on the IOTA Tangle.
