We are updating the way Solana Token Wallets are created on the Fireblocks platform.
What is changing?
Until now, when you created a Solana token wallet on a vault, we would immediately create the corresponding token account on-chain. This required a blockchain transaction and incurred two types of costs:
- Transaction fee: the network fee for creating the token account.
- Rent: a fixed amount of SOL locked on the token account for as long as it exists. The Solana blockchain uses rent to incentivize efficient use of storage and prevent the network from becoming bloated with unused or inactive accounts. The rent amount is required to activate a new token account.
With this change, once you create a Solana Token Wallet on a vault, we will no longer automatically perform the on-chain transaction to create the token account. Instead, the token wallet will be created as a representation inside Fireblocks only. The token account will be created on-chain upon the first incoming transaction, with the sender covering the rent cost.
Why this change?
This adjustment helps you avoid unnecessary costs until you actually need to use the token account on-chain.
How does this affect you?
You will avoid unnecessary rent and transaction fees until the token account is actually used
Creating a new Solana token account will not initiate a blockchain transaction. Therefore, no signing is required for this process
If you are using the API to create new Solana token accounts, wallet activation must no longer be used
This new behavior will be applied for all customers by default on December 17th, 2025.
To enable this new behavior on your tenant before that date, contact the Fireblocks Support team.
