Coin to FA: A Seamless Token Standard Upgrade on Aptos
Starting June 30, 2025, all tokens on Aptos will begin migrating automatically from Coin v1 to the FA standard. APT will be the first to transition, with other token addresses to follow. No action is required from users. This behind-the-scenes upgrade, triggered by ecosystem contributor Aptos Labs, will occur seamlessly across the network.
What's Happening
June 20, 2025: FA becomes the default for all new accounts.
June 30, 2025: APT balances migrate, fully automated
Alt‑coin migrations run quietly in the background.
Legacy coin modules go into maintenance mode; FA‑only docs published.
Why This Matters
The shift to the unified Fungible Asset (FA) standard brings long-term architectural and usability improvements across the Aptos ecosystem. By phasing out the legacy Coin model, this upgrade simplifies token management, improves network performance, and sets a strong foundation for the next wave of DeFi and RWA innovation.
Seamless compatibility: One unified FA standard removes Coin vs. FA branching across wallets, CEXs, DeFi protocols and custodians.
Smarter token storage: All balances collapse into deterministic FungibleStore objects, shrinking global state and speeding up node spin-up & state‑sync.
Protocol simplification: Deprecating

How It’s All Happening
Prep Work (Done). Feature flags already make new accounts FA‑native.
APT token Migration (June 30). A bulk transaction submitter converts ~80 M CoinStore<APT> entries. Gas is pre‑funded with no cost to users or dapps.
non-APT token Migration (June 18–22). The same tool handles other tokens, prioritized by holder count.
Real‑time Safeguards. Throughput is rate‑limited, with kill‑switches if latency spikes. Ecosystem engineers are on‑call 24 / 7.
What You’ll Notice
Here’s what the migration means for you, depending on how you interact with the Aptos network:
Everyday user: Nothing to do. Your tokens stay safe, and transfers may even get cheaper after the migration completes.
Wallet: If you already show FA balances, you’re done.
Exchange / custodian: Most have finished FA roll‑out
Developer: Existing code keeps working, but new work should use the FA interface exclusively.
FAQ
Does anyone have special privileges to modify my account?
No. At the framework level, this conversion mechanism is safely built-in and can be called by any user to convert their own existing account. No entity has special privileges over user accounts.
Will gas fees spike during the upgrade?
No. Transactions are going to be rate‑limited during the migration and the gas is subsidized.
What if my exchange isn’t FA‑ready yet?
They’ve been notified. You may see temporary deposit/withdrawal pauses, nothing more.
Can I still use coin API calls?
Yes—they will be available in maintenance mode, silently proxy to the FA and
Do I need to do anything during the migration?
No action is required from users. The migration is fully automated. But if you have questions or want to learn more, join the community chat on Discord or Telegram. Engineers from Aptos Labs will be available 24/7 during migration week.
