Which CEXs paused ADA deposits?

TLDR

Coinbase, Kraken, and Upbit paused ADA deposits and withdrawals during the recent split of the Cardano (ADA) network while exchanges validated chain consensus, then later resumed services Cardano on CoinsKid and as reported by a market update.

1. Coinbases pause lasted about 14 hours per a detailed report from The Block.
2. Pauses were precautionary while nodes reconverged to a single canonical chain, confirmed in a market update.
3. Deposits/withdrawals reopened after emergency patches and reconvergence, with no user funds lost per a Coindesk report.

Deep Dive

1. Named Exchanges

Multiple large centralized exchanges paused ADA operations as the network split into two competing histories. Reports explicitly name Coinbase, Kraken, and Upbit as pausing ADA deposits and withdrawals during the incident, with Coinbases disruption spanning roughly 14 hours according to The Block and corroborated by a market update.

2. Why Pauses Happened

The Cardano (ADA) network briefly split after a malformed delegation transaction exposed a legacy validation bug, leading newer and older nodes to disagree on ledger state. Exchanges paused flows to avoid settlement on the wrong branch until consensus was verified, which is a standard risk control during on-chain instability, noted in a market update.

3. Duration and Resumption

Engineering teams released emergency patches and instructed upgrades, after which the chain reconverged and exchanges resumed ADA services. Coverage notes no user funds lost and a phased return to normal operations once consensus was restored, per Coindesk and the market update.

Conclusion

Coinbase, Kraken, and Upbit paused ADA deposits and withdrawals as a precaution during Cardanos temporary chain split, then restored services after patches and reconvergence. This pattern is typical for CEX risk controls during chain instability and aims to protect user funds and transaction integrity.
