Onchain Passport

You can optionally mint your Passport onchain for partner campaigns that require it.

How It Works

Onchain Passport uses the Ethereum Attestation Service to create a verifiable attestation of your Passport data on the blockchain.

Cost

Minting costs approximately $3 plus gas fees. Using a Layer 2 network such as Optimism is recommended to minimize gas costs.

Benefits

• Smart contract retrieval — Partner applications can read your Passport data directly from the blockchain via smart contracts.
• Server independence — Your credentials exist on-chain and do not depend on any centralized server being available.
• Permanent credentials — Your onchain attestation persists as a tamper-proof record on the blockchain.

When to Mint

Not every user needs an onchain Passport. Mint yours when a partner application or campaign specifically requires onchain verification.
