Supported Chains

AIR Kit supports multiple blockchain networks. The available chains depend on your partner configuration. Mainnet Chains:
  • Base (Chain ID: 8453) - Default mainnet chain
  • BSC (Chain ID: 56)
  • Gnosis (Chain ID: 100)
  • Kaia (Chain ID: 8217)
  • Soneium (Chain ID: 1868)
Testnet Chains:
  • Base Sepolia (Chain ID: 84532) - Default testnet chain
  • BSC Testnet (Chain ID: 97)
  • Gnosis Chiado (Chain ID: 10200)
  • Kairos (Chain ID: 1001)
  • Soneium Minato (Chain ID: 1946)
  • Sepolia (Chain ID: 11155111)
Devnet Chains:
  • Moca Devnet (Chain ID: 5151)

​
Chain Configuration

Chains are configured per partner through the partner configuration: 
// Partner configuration example
{
  chainId: "8453", // Default chain (Base mainnet)
  enabledChainIds: ["8453", "56", "100"] // All supported chains of that partner
}

​
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.

Credential Operations (Moca Chain)

​
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.
