Following the previous architecture contest: Contest: Dune → FreeTON Swap Architecture - #2 by cryonyx

Contest dates

Submission period : 3 calendar weeks after approving this proposal in the governance interface;

Judging period : 1 calendar week after the submission period.

Short description

Implement Stage 1 of the winning architecture of the Dune → FreeTON Swap Architecture contest with the milestone “Initial Implementation”.


Chained contest


  1. Initial implementation (relays and smart contracts), testing on testnet and mainnet
  2. Relays Deployment and Merge Execution


Merge with the Dune Network blockchain and its community in order to increase the

resources and joint development of the Free TON community.

The FreeTON part of the relay should be as generic as possible to be reused for following merges with other protocols.

General requirements

  • Cross-chain passing of swap orders from Dune to FreeTON with censorship resistance
  • The protocol must have protections against a minority of byzantin relays
  • The possibility of trustless and non-custodial transfer of value between networks
  • Code and documentation should be published in open-source at GitHub/GitLab or another open repository

Fair play

As per Procedural remarks on contests.

    • Watching the FreeTON network for revelations to update DB
    • Watching the DB to propagate revelations to Dune Network
    • Getting a relayer status
  • FreeTON and Dune Network smart-contracts
  • Web Interface for Dune holders to create swaps
  • Link to documentation at Github/Gitlab or another open repository, with the obligatory backlink to your submission in the repository’s README

Great! I think time for this contest should be a bit longer

Please think about Dune people who are waiting for this swap.
It’s already too long, very too long.

The swap should already have been begin !!!

So, now, please stop doing proposals and proposals.

Ça devient complètement dingue, après cela on arrivera à 6 mois pour créer un swap :disappointed:

As I told Pavel, we lost a lot of time because we didn’t really understand the whole governance process for a while. Having a completely decentralized governance is great, but it comes with some drawbacks… Anyway, if this proposal is voted, the merge should start just at the end, in about 4 weeks, and the Dune community will be part of the Free TON community a few days after. I think it’s close enough that it’s worth being patient. It gives us some time to better test the merge and document the whole process for users.

The ORL team is going to send his submission !

Due to the issue with jurors’ notification about the contest I propose to extend the voting period for 1 additional week.


Dune → FreeTON Swap Implementation Stage 1

New voting deadline


Special remarks

The currently existing single vote of juror 0:104bfaf ···· ec848ad61 should be counted together with the votes received with the extension period. This juror should be eligible for getting the corresponding jury reward.

For the sake of keeping the track record of this vote, I hereby attach its screenshot.

We are already quite late on this merge, I don’t really see the benefit of adding one extra week just for this single-submission contest. What about starting a short “Audit” contest instead ? I think it would give an extra opportunity for jurors to look at the code, and benefit the project with reviews and maybe catching some bugs.

Thanks Fabrice, that’s great idea. we’re all been waiting for the swap to start so we can participate in the TON ecosystem. Owning the token is the start!

This merge is too long.
Ok for one more week (already started by the way…), but after that, swap has to be online !

Does anybody know the TON contract address for the Dune-TON SWAP?

The swap is still under development, as this proposal contains modifications from the original specification. So the contract is not yet deployed on the network.

So the swap STILL hasn’t occurred?
