Fees
Salt is designed to charge for usage, not access.
Fee model
Salt is designed around action-based fees. This means fees are charged for specific paid actions, rather than through monthly subscriptions, seat-based pricing, or minimum spend requirements.
Fees will be charged as follows:
| Action | Fee |
|---|---|
| Account creation | $10 USDC |
| Transaction signing | $0.10 USDC per signed blockchain transaction |
The account-creation fee is a one-off charge, paid before the account is created. A single account works across all supported chains — the one-time fee covers them all, with no separate per-chain setup or activation fee.
Salt fees are charged in USDC on using signed payment authorisations.
Fees can be paid in USDC held on the following networks:
- Base, Arbitrum, Polygon, Avalanche, Ethereum on Mainnet
- Arbitrum Sepolia, Base Sepolia on Testnet
Sponsored fees
Salt is designed to support different payment models.
A paid action may be paid by:
- the user directly
- a fintech or application sponsoring the user
- a Salt Account, where the relevant policy permits it
Sponsored fees allow fintechs and applications to abstract Salt fees from their end users where appropriate.
Fee settlement
Salt fees are settled on-chain.
Fees can be paid from either a nominated Salt acccount or an external wallet, chosen by the Account initiator or transaction proposer.
