About
Built for the multi-rollup future.
Tesseract is a protocol made by Cryptuon, an open-source-first lab focused on the trust-minimised plumbing of cross-chain DeFi. We work on the layer where multisigs, optimistic dispute windows, and validator quorums quietly become someone else's problem.
The protocol is named after the four-dimensional analogue of the cube — a structure that, like cross-rollup settlement, only makes sense once you stop trying to project it onto a single chain. The hypercube has eight cells; Tesseract coordinates atomic swaps across as many rollups as you point a relayer at.
What we believe
- 01
Trust assumptions should be visible. If a protocol bottoms out on "13 of 19 nodes are honest", that should be on the front page, not buried in a whitepaper appendix.
- 02
Small contracts are easier to audit. Seven Vyper contracts at ~45kB total is a feature. So is choosing Vyper.
- 03
MEV protection belongs in the base layer. Asking each integrator to roll their own commit-reveal is how value leaks out of an ecosystem.
- 04
Open source means open source. No "community edition", no enterprise vendoring, no plug-and-pay licence keys. MIT, all of it.
- 05
Status pages should be honest. Our README says "Testnet Deployment: Ready. Security Audit: Pending." That is the unvarnished state. We'd rather lose you to a competitor than mislead you.
Lineage
Tesseract draws conceptually on the CRATE Protocol research paper on commitment-and-resolution schemes for cross-rollup atomic execution, the long tradition of HTLC-based atomic swaps going back to the Bitcoin Lightning era, and the day-to-day experience of building cross-chain DeFi infrastructure that we wish someone had handed us five years ago.
The contracts are written in Vyper. The relayer is built on ethers-rs. The infrastructure is described in Terraform. None of these choices are accidents.
