D17

An open-source Ethereum launch experiment with published rules, participant-owned lockers, explicit refund windows, permissionless lifecycle actions and permanently locked protocol liquidity.

D17 was shaped around @xbt2027's vision: a token launch should not depend on participants trusting promises made off-chain. Its schedule, exits, supply treatment, settlement path and liquidity rules should be visible before anyone commits, then enforced by contracts rather than operator discretion.

The three repositories

| Repository | Start here for |
| --- | --- |
| D17 | The complete runnable release: participant terminal, wallet deployer, direct-RPC mode, optional self-hosted read API, contracts, tests and public deployment manifests. |
| D17 documentation | Plain-language participant and deployer guides, architecture, contract reference, self-hosting instructions and the OpenAPI/Scalar reference. |
| D17 contracts | A small Solidity-focused mirror containing the production contracts, tests, ABIs, deployment manifests and contract explorer. |

What the mechanism does

• Publishes one immutable launch configuration before commitment begins.
• Uses five timed rounds with declared refund windows and costs.
• Keeps each participant's WETH in their own locker until refund or settlement.
• Allows permissionless finalization, post-grace settlement and official-pool creation.
• Sends official LP tokens to a vault with no withdrawal path.
• Supports late settlement without redirecting a participant's tokens or residual WETH.
• Lets the website run directly from user-supplied Ethereum RPC endpoints; the indexed API is optional.

Live showcases

• Sepolia terminal and deployer
• Ethereum mainnet read-only terminal
• D17 guides
• API and contract reference

The hosted pages are temporary public demonstrations of the software, not a custodial service. Transactions are signed by the user's wallet and sent directly to the selected Ethereum network.

> Experimental software: D17 has extensive local and Sepolia test evidence but has not received a formal professional third-party audit. Mainnet uses real ETH and WETH. Review the source, deployed bytecode, launch configuration and every wallet transaction independently.
