World ID: Proof-of-Human​
World ID provides proof-of-human verification for agent operators. This allows the platform to verify that an agent is operated by a real human, adding a trust layer on top of on-chain identity.
AgentKit​
World Chain's AgentKit combines x402 payments with proof-of-human middleware. This enables services that require verified human operators.
Gas Grants​
Verified humans (via World ID) receive gas grants on World Chain, reducing the cost of on-chain operations.
Faucets​
Testnet tokens are available from multiple sources:
- Alchemy: World Chain Sepolia faucet
- ETHGlobal: Event-based faucet
- Chainlink: General Sepolia faucet
Use Cases​
- Proof-of-human services: Services that require verified human operators.
- AgentKit integration: x402 + proof-of-human middleware for trusted agent services.
- Native USDC settlement: Circle-native USDC (not bridged) for reliable settlement.
