# Cross-chain Fees

1. Asset deployment fee 

Projects that choose ShuttleOne to deploy on multichain are required to hold a minimum balance of $SZO in their developer wallet. The $SZO amount is deducted for transactional fee across Metachain.

Minimum $SZO amount for development starter (as of Mar 2022): 500,000 $SZO.

  2\. Transactional fee

Enterprise wallets must hold a minimum of $SZO50,000 (fifty thousand Shuttleone tokens) Consumer Wallets must hold a minimum of $SZO10,000 (ten thousand Shuttleone tokens).

SZO is used in the provision for cross chain transactions without the need of any protocol tokens.

Metachain transactional fee is: selected chain gas fee amount + 5 SZO.
