Checkpoint Oracle
The Points Oracle is Checkpoint’s verification layer. It fetches points data from offchain sources and signs it with cryptographic signatures, making the data verifiable onchain. The Oracle is a core component of Checkpoint and is responsible for writing points data to the blockchain, verifying claims and settlement among other things.Checkpoint NFT

Oracle Functionalities
The Oracle serves two major functions: verifying offchain point deposits before they go onchain, and confirming settlement claims when protocols TGE. Fundamentally, these translate to various programmatic features:Signature Verification
Checks account-owner authorization and signs verified points balances
Tracks Points Changes
Reviews balance changes before updating supported points programs onchain
Settlement Verification
Confirms that offers were settled correctly on-chain, on supported chains
Vesting Status
Provides vesting status checks and claimable amount calculations for settlement
Deposit Reviews
A first deposit can be available immediately, partially available, or placed under review, depending on the program’s account limit and shared capacity. Delayed deposits need matching observations, a review period, and a fresh balance check. Follow the reported deposit status for progress; scans, backlogs, or pauses can extend the wait. You can follow progress without signing repeatedly. When a deposit is ready, authorize it again and submit the short-lived claim. If you already deposited the available portion, the oracle reviews and updates the remainder automatically. Unusual balance changes or source outages can pause oracle updates while they are checked.Oracle Process Breakdown
The Oracle components can be further viewed more granularly by examining the Oracle’s workflowSignature Verification
1
Deposit Authorization
Users request a short-lived authorization payload and sign it as the underlying points
account owner
2
Oracle Claim Generation
The Oracle verifies that authorization, fetches the latest points balance, and signs the
deposit claim, subject to capacity limits and review
3
Onchain Deposit
The operator submits the Oracle-signed claim onchain so the confirmed balance becomes
tradable
After verification, users should receive a Soulbound Checkpoint NFT
Balance Monitoring
1
Automatic Points Balance Change
The oracle checks supported programs periodically for points balance changes
2
Balance Confirmation
Matching observations and a review period are required before balance updates are released
Settlement
1
Settlement Activation
Triggers settlement processes when protocols TGE
2
Balance Reconciliation
Reconciles final token distributions with traded point amounts to ensure accurate settlement
3
Crosschain Verification
Coordinates token distribution across multiple chains using LayerZero infrastructure
