Aptos quietly migrates all tokens to the improved Fungible Asset standard without requiring user action.

Aptos Labs (APT) is quietly phasing out its original Coin standard in favor of the improved Fungible Asset or FA standard. The transition officially kicks off June 30, 2025, starting with Aptos’ native token, APT, and smoothly moving on to other assets shortly afterward. 

Luckily, everyday users won’t have to lift a finger; the migration happens automatically behind the scenes.

Aptos’ legacy Coin model had limitations, particularly around token management, state synchronization, and integration complexity. The FA standard solves these problems with clearer token storage methods, shrinking global blockchain state sizes and significantly speeding up node spin-up times. 

Translation: fewer delays, cheaper transactions, and smoother user experiences.The migration’s practical benefits extend to every corner of the Aptos ecosystem. 

Wallets, exchanges, and DeFi protocols no longer need complex branching between FA and legacy Coin implementations. This unified standard reduces the code complexity dramatically, meaning quicker audits, smaller attack surfaces, and tighter overall security.

Future-proofing composability is another major benefit. Legacy coins eventually hit a complexity ceiling, becoming tough to integrate into sophisticated DeFi applications. The FA standard provides a cleaner, extensible framework, ideal for evolving use cases in decentralized finance and real-world asset tokenization.

Developers can focus on innovation rather than wrestling with complicated legacy compatibility issues.

Their confident the migration will unfold smoothly. Aptos Labs already activated FA for all new accounts, preparing the infrastructure well in advance. The bulk transaction submitter handles the transition for approximately 80 million APT entries, ensuring no downtime or disruption for users. 

Aptos has thoughtfully rate-limited the process and included a kill-switch if unexpected issues arise, with engineers on-call 24/7 during the migration week (any other protocols/networks/chains reading this? This is how you make sure people don't panic).

Exchanges and custodians are mostly ready, though users might experience minor temporary pauses in deposits or withdrawals if their chosen platform lags behind. 

The overall message from Aptos is clear and reassuring: users don’t need to do anything except watch their tokens seamlessly upgrade to a better standard. It’s blockchain innovation delivered quietly and effectively, exactly how it should be.
