On-Chain Evidence

Every flow documented below was tested on mainnet with real contracts, real tokens, and real funds. Transaction hashes are permanent on-chain proof.
Verify on LayerZeroScan: Cross-chain transactions that use LayerZero messaging can be tracked at layerzeroscan.com by entering the origin transaction hash. You’ll see the message flowing through LayerZero’s DVN and executor infrastructure.

Solana Cross-Chain Operations (Cross-VM via LayerZero)

These are the headline flows — Solana ↔ Base via LayerZero V2 cross-VM messaging.
#OperationResultTime

Cross-VM highlight: The Solana CC Buyer program ABI-encodes buy parameters in an Anchor program and sends them via LayerZero to CCBuyerV3 on Base (EVM). This is a live, production cross-VM interaction: Solana → LayerZero → EVM.

​
Cross-Chain Token Launches (Remote → LZ → Base)

Three tokens launched from three different chains, all deployed on Base via LayerZero messaging:
#OriginLauncherToken CreatedEvidence
15BSCRemoteLauncherLZDEMOBNB — 0x1f62c651...LZ message → factory.launchFor()
16EthereumRemoteLauncherLZDEMOETH — 0xde6f6f27...LZ message → factory.launchFor()
17SolanaToken LauncherLZDEMOSOL — 0x7cbd2ed2...Solana TX
All three tokens verified on API, indexed, and tradeable from any supported chain.

​
Post-Launch Cross-Chain Buys

After launching tokens from remote chains, we verified cross-chain trading works on those tokens:

OFT Bridge Configuration Fix

During E2E testing, we discovered that OFT bridges from Base to all remote chains were blocked due to a ULN confirmation mismatch (outbound default: 5, remote requirement: 10). Fix transactions (setConfig on LZ Endpoint):

These transactions demonstrate deep understanding of LayerZero’s ULN configuration and DVN requirements.

23 of 24 tests pass. The single failure is external — Across Protocol deprecated Avalanche support. LayerZero OFT bridging to Avalanche remains fully functional.
