# Contribute to TrustLink Labs: Research, Code, and Docs

> How to contribute to TrustLink Labs protocols, research, and reference applications. Links to GitHub repos, research library, TSN blog, and X.

TrustLink Labs welcomes protocol engineers, cryptographers, security researchers, distributed-systems developers, technical writers, and open-source contributors.

## Contribute

The best way to start is to inspect the code, reproduce the Devnet flows, and propose improvements against the source.

* [TrustLink Labs on GitHub](https://github.com/Trustlink-Labs)
* [TrustLink Pay repository](https://github.com/bigdreamsweb3/trustlink-pay)
* [TrustLink Labs Research library](https://github.com/Trustlink-Labs/Trustlink-Research)
* [TSN Receiver](https://github.com/bigdreamsweb3/tsn-receiver)
* [TSN Node](https://github.com/bigdreamsweb3/tsn-node)
* [TSN RPC Gateway](https://github.com/bigdreamsweb3/tsn-rpc-gateway)
* [TSN research blog](https://tsn-protocol.blogspot.com)
* [X / @TrustLinkLabs](https://x.com/TrustLinkLabs)

For cross-network work, contributors can participate in route research,
liquidity review, contract review, operator testing, incident analysis, and
community route proposals. A route proposal must include technical evidence;
community interest alone does not activate a settlement route. See [Community
and route governance](/about/community-and-governance).

## Integrate

If you are building on TSN, start with the developer path:

1. [Getting started](/developers/getting-started) — install the SDK and submit your first intent.
2. [Security invariants](/security/invariants) — understand the canonical rules that govern every payment.
3. [Payment intent lifecycle](/developers/payment-intent-lifecycle) — walk through the full flow from intent to settlement.
