# Deplo > Ship Ideas Into Reality. A simpler path from repository to production. Deplo is a release ledger on Robinhood Chain (chain id 4663). It reads public GitHub repositories (details, branches, recent commits, the root file list, package.json and Node version files only) and derives a build plan: framework, package manager, install and build commands, output folder and Node version. A wallet registers a project for a repository and records preview and production releases (commit, optional build fingerprint, URL, label); it can promote a preview and roll back to an earlier production release. A server-side health check reports a release URL's status code and latency. Deplo does not build or host code; hosted builds and hosting are planned. ## Pages - https://deplo.lol/console: repository reader, release ledger, environment names (kept in the browser), health check - https://deplo.lol/live: full-screen release stream - https://deplo.lol/contracts.json: chain, address and ABI ## Contract - DeploReleaseBook: 0x58e88d61aa2ef8e42a30b953f8b7989d436aab9e - registerProject(string repo); recordRelease(uint256 projectId, bytes20 commit, bytes32 artifactHash, string url, string label, uint8 env); promote(uint256 previewId); rollback(uint256 releaseId) - reads: getProject(id), getRelease(id), releases(fromId, limit), releaseIdsOf(projectId, offset, limit), projectIdsOf(owner, offset, limit) - env 0 = preview, 1 = production; repoHash = keccak256(lower-case owner/name); no owner, no fees, never holds funds ## Token - $DEPLO: not launched yet. Community token with no promised value. Deployment credits, build capacity and premium features are planned, not live.
