Chain Configuration

Chains are configured per partner through the partner configuration:

Gas Cost Reference

Gas costs on AIR Kit operations are paid in the native token of the selected chain (or sponsored via Paymaster). The table below shows approximate gas units for common operations. Actual $MOCA costs for Moca Chain credential anchoring are listed separately.
These benchmarks reflect Testnet measurements as of Q1 2025. Mainnet costs may differ. Enable Gas Sponsorship (Paymaster) to abstract all gas costs from your end users.

EVM Chain Operations (Base, BSC, Gnosis, etc.)

​
Gas Sponsorship

Use the Paymaster to cover all user-facing gas costs from a pre-funded developer wallet. This removes all on-chain funding friction from your end users — they never need to hold or manage gas tokens.
