Sail Sail

Open-Source Licenses

Last updated: July 1, 2026

Both Sail products are open-source software. Your rights to use, copy, modify, and distribute the software come from these licenses — not from the Terms of Use. Nothing in the Terms of Use limits, conditions, or revokes any right these licenses grant. If the Terms of Use and an open-source license ever conflict as to the software, the license controls.

The authoritative license text is the LICENSE file (and the per-file SPDX-License-Identifier headers) in each source repository. The summary below is for convenience only.

Sail Protocol

Section titled “Sail Protocol”

Sail Protocol is mixed-license, and it is not accurate to call it simply “GPL”:

  • Kernel and core contracts — GPL-2.0-or-later. This covers the SailKernel, the mandate factory, governance, fee policy, permission templates, and related core contracts. Copyleft: distributing modified versions of these contracts carries the GPL’s source-availability obligations.
  • Interface contracts — MIT. The contract interfaces (the contracts/interfaces files — e.g. IPermission, IFeePolicy, IOracle, SailCapabilities) and the Safe module-enabler helper are MIT-licensed, so you can build against and integrate with the protocol permissively.

Each Solidity file declares its own license in its SPDX-License-Identifier header; that header is authoritative for that file.

Sailor

Section titled “Sailor”

Sailor — the TypeScript toolkit, CLI, and SDK — is licensed under the MIT license in full.

Third-party components

Section titled “Third-party components”

Both products depend on third-party open-source components, each under its own license (for example, Safe contracts and libraries, and the viem library used by Sailor). Those components are governed by their respective licenses, which are included with their source.

Trademarks are not licensed

Section titled “Trademarks are not licensed”

These open-source licenses grant rights to the code only. “Sail,” “Sailor,” and related names and logos are trademarks of Agentic Finance Inc. and are not licensed under GPL, MIT, or any other license here.
