A pass lets a wallet claim from a participating campaign while a relayer pays the BNB network fee.
Claim passes
Open the campaign link from its organizer and connect the wallet that received the pass. The pass is bound to that wallet, to the claim contract and to a cutoff time. A pass can be used once.
Campaigns
Set a claim limit, closing time, voucher issuer and relayer. Fund the relayer with BNB, then allow invited wallets to request a pass. An active relayer and its campaign budget are required for new claims to proceed.
Signing
Your wallet asks you to sign typed data for one claim. Check the campaign contract, recipient and expiration before approving. The relayer sends the transaction from its own BNB balance.
Spare supports campaigns built for this flow. Each campaign needs its own contract configuration and a funded relayer.
Claim status
After the relayer submits, the app links to the transaction on the configured BNB Chain explorer. A confirmed claim requires a successful transaction receipt.
Public network test
On BNB Smart Chain Testnet, a wallet with zero tBNB received collectible #1. The sponsor sent the transaction and paid 0.0000155878 tBNB for gas.
