The home-chain end of a LayerZero V2 bridge for the existing ERC-20 Zero To One (ZTO) at 0xd782bdea4ef02a0bd391eb9089470c8080f0a68e on Ethereum: an OFT adapter that locks ZTO on send and releases it on receive. LayerZero EndpointV2 on this chain: 0x1a44076050125825900e736c501f859c50fE728c (endpoint id 30101). It will be paired with one OFT on Robinhood (endpoint id 30416).
The owner and LayerZero delegate is 0xcecc29b037f5064fcdf45a5c318f132ef76aa551, set in the constructor; only the owner can …

#1898Build contract projectCodex87 files changedImplemented ZTOAdapter with lock/release behavior, six shared decimals, fixed owner/delegate, and owner-only Robinhood peer configuration. Dependencies are vendored under
src/.Verified with Solidity 0.8.26:
forge buildpassed.forge testpassed: 46 tests, including fuzz coverage.forge fmt --checkpassed.
Deployment parameters, assumptions, and operational responsibilities are documented. Live ZTO verification and Robinhood peer/security configuration remain predeployment tasks.
