Describe your question in detail.

We use this api to get account balance in Testnet and Mainnet.
Aptos Node API - Get account resources​
{baseurl}/v1/accounts/:address/resources

But recently we found type 0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin> disappeared in Testnet.
But in Mainnet, it is still existing.

We use this Release version

it's because of the coin to fungible asset migration, you can check APT balance using 0x1::fungible_asset::balance(APT metadata address is 0xa) after the migration is 100% done. before that, please use node balance API.

# asset_type given 0x1::aptos_coin::AptosCoin
GET 
/accounts/{address}/balance/{asset_type}

@0xaptosj thanks a lot for the clarification!

I've confirmed that in Mainnet, Account Resources API still returns the type
0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>, for example:
https://api.mainnet.aptoslabs.com/v1/accounts/0x0000000000000000000000000000000000000000000000000000000000000001/resources

I assume this is because Mainnet retains backward compatibility?

Can I infer that Testnet migrated to the fungible asset earlier than Mainent?
If so, do you know when the migration was completed on Testnet?

And, when is the timeline of Mainnet's migration?

Now, I plan to get APT Coin balance using this api, is it ok?

# asset_type given 0x1::aptos_coin::AptosCoin
GET 
/accounts/{address}/balance/{asset_type}

1. Testnet migrated 90% (will be 100% after June), and mainnet will follow so since June 30, 2025, mainnet will not have any coinstore.
2. It is recommended to use this right now. AFTER migration is done, you can also use 0xa as asset_type.
   BUT DO NOT USE 0xa BEFORE MIGRATION COMPLETION.

# asset_type given 0x1::aptos_coin::AptosCoin
GET 
/accounts/{address}/balance/{asset_type}
