What NFTeria builds

UNICA, release by release.

UNICA is NFTeria's current product: an MIT-licensed settlement hook and modular integration layer for Uniswap v4. It is offered as MIT-licensed work anyone is free to read, run, fork and extend. Dependencies keep their own licences. There are no plans and no prices here. UNICA is testnet only.

Every capability is stated at the rung it has actually reached.

Live · testnet: Running on a public testnet today. Settlements link to their explorer; other rows link to the record that shows them.
Deployed: Code at an address with verified source; nothing settled through it.
Experimental: Ran on a testnet outside the release line, with its caveats stated.
Blocked: Written, not shipped, held back by a finding.
Simulator only: Runs in a simulator, never on a real network.
Read only: Reads live state and prepares a preview; sends nothing.
Designed: Being designed. Not built, not deployed.

UNICA V1

Live on Ethereum Sepolia

UNICA V1 is live on Ethereum Sepolia. Its hook and executor are source-verified on Sourcify as a partial match, and one settlement ran through Uniswap's Universal Router: 0.001 ETH in, 2.003660 USDC out.

Anyone can re-prove the V1 deployment from the chain with the repository's own script, bash docs/proof/verify-live.sh.

Blocked

UNICA V2

A frozen release candidate, deployed nowhere

V2 is written and frozen as rc1. It is not shipped. Release is blocked pending remediation and re-review of an internally identified Critical finding.

UNICA V3

Live on Ethereum Sepolia; deployed on three more testnets

UNICA V3 settled its first payment on Ethereum Sepolia on 2026-09-10: 0.001 ETH in, 2.216294 USDC out. A rehearsal against live chain state had printed the same number before the transaction was signed.

The same day, a V3 settlement was made in a browser through the published page. The checkout quoted 1.774099 USDC from the pool's live state, and the chain paid exactly 1774099 units. In that payment the merchant was a name, nfteria.eth, resolved on ENSv2 Sepolia and shown to the payer before anything was signed.

V3 is deployed and source-verified at one address on four testnets: Ethereum, Unichain, Base and Arbitrum Sepolia. It has settled payments only on Ethereum Sepolia. On the other three it is deployed and bound, and has settled nothing.

Experimental

One order on Robinhood Chain testnet

A separate experimental hook and executor, chain id 46630

Experimental, testnet only: on 2026-09-11 a separate experimental hook and executor settled one order on Robinhood Chain testnet (chain id 46630). The order took 0.001 faucet TSLA in and paid 0.393052 uTUSD to the merchant. It was paid by NFTeria's deployer, against liquidity NFTeria seeded, at a demonstration rate NFTeria set.

The faucet TSLA is a testnet token with no real-world value, not a share or a security, and uTUSD has no value. There is no oracle, and the contracts' source is not verified on the explorer. No tokenized equity is supported. The record lives on a separate branch and tag of the repository, not on its main branch.

Designed

UNICA v4

The next UNICA release

UNICA v4, the next UNICA release, is being designed now. It is not built or deployed. It will be a separate deployment with its own addresses and records, not an upgrade of any contract deployed so far.

The repository's unicaV4 branch carries unreleased groundwork for it. That groundwork is not a release and is not published. Apart from the experimental Robinhood testnet contracts above, which are not UNICA v4, nothing added on that branch is deployed.

UNICA v4 is a UNICA release name. It is not Uniswap v4, the AMM that UNICA is built on.

Around the releases

The rest of what UNICA touches, at its rung.

Live · testnet The Graph
A subgraph on The Graph's Subgraph Studio indexes the settlement receipts of both live UNICA hooks on Ethereum Sepolia, V1's and V3's. Its query endpoint takes GraphQL over POST: https://api.studio.thegraph.com/query/1755384/unica-settlements/v2-39b6f91 The record in UNICA's README
Live · testnet ENSv2 on Sepolia
unica.eth is registered on Sepolia, and its ENSv2 delegation was broadcast in 12 transactions, in blocks 11670554 to 11670579, every one status 1. The record in UNICA's README
Simulator only Chainlink CRE
The Chainlink CRE workflow runs only in Chainlink's simulator. It has never run in a real TEE or DON.
Read only Arc
On Arc testnet, UNICA reads a live position and prepares a signable preview, but broadcasts nothing. No UNICA contract runs on Arc, because Uniswap is not deployed there.
Designed Merchant treasury automation
Merchant treasury automation is not deployed. Its control model is being designed and tested, and until it exists nothing autonomous touches a merchant's funds.
Designed Cross-chain settlement
Cross-chain settlement is designed, not implemented.
Live · testnet Pools and payout currency
There is no configurable allowlist. Each live UNICA hook admits only a pool of native ETH against one payout currency per chain, fixed in its code, and refuses to initialise any other pool. Supporting another payout currency needs a new deployment. UNICA's security policy

What a receipt proves.

The receipt proves that the order it names was paid through the official router by the executor, and that the recipient's balance grew by at least the minimum in the same transaction. It does not prove the price the payer would have got elsewhere.

No part of UNICA has been audited. Testnet only. There is no mainnet deployment and no real value at risk.

NFTeria is an independent builder. UNICA is not commissioned by, affiliated with, endorsed by, or reviewed by Uniswap or any other ecosystem named here.
