ORACLE-ATTESTED SETTLEMENT · SOLANA → BASE

Sports results, proven once.
Settled everywhere.

TxLINE commits scores to Solana. Proofline verifies them with TxLINE's own on-chain verifier, carries the outcome across Wormhole, and finalizes on Base — two independent lanes racing to the same digest. A relayer can delay an outcome; it cannot change one.

Replay of a recorded run — Canada 2–1 France. Two lanes race to one digest on real timestamps.

Solana Mainnet Exhibit

The deployed program, the real verify_outcome transaction, and the memo-anchored attestation — formal evidence, self-explaining.

The dual-finality guarantee

Two lanes, one digest

Dual finality: fast lane (RPC quorum, provisional) and proof lane (Wormhole VAA) must independently derive attestation 0x062f6f5c…061d6d. Settlement requires both to agree — contracts live on Base Sepolia ↗.

What a proof establishes

CRE provides liveness. TxLINE, Solana, and Wormhole provide correctness. A relayer can delay an outcome, but it cannot change one. A proof uploader can submit arbitrary bytes, but the Solana adapter emits only after TxLINE's canonical verifier returns true. Base accepts only a valid Wormhole VAA from the registered emitter.
