# CenterChain

> A Cosmos SDK chain for tokenized assets.

CenterChain is a Cosmos SDK application chain with five modules of its own. It records token
and NFT ownership, the rules that govern moving them, liquidity pools, an NFT secondary
market, income distribution, and a two-phase swap authorization. It does not model what an
asset represents, and the chain cannot prove who holds a token.

One public network exists today: `centerchain-testnet-1`. There is no production network. Its
test tokens are valueless.

This file is a map, not marketing. Every claim below carries the file and line of the
canonical documentation it came from, and every statement about what is not available is a
measurement rather than a forecast.

Measured: 2026-09-30. Route list as published on the same date.

## What the chain is

- Cosmos SDK application chain with five modules of its own: token factory, liquidity, NFT,
  NFT market, income.
- Every bank send, NFT send and swap settlement passes through one transfer decision function.
- A transfer can be rejected by a per-denom blacklist or by a restricted-denom rule. There is
  no account level freeze on the chain.
- A swap between two token factory denoms outside a pool is two transactions: the holder signs
  a limited permission, a named executor settles inside the bounds the holder set.

Version note: the bare `/docs/` path is the current release, `/docs/next/` is work in progress
and is not indexed, and a frozen version moves to `/docs/<version>/`. No frozen version exists
today.

## Not published today

Each row is a measurement or a documented absence. None of them is planned work written as a
promise.

- No production network. The documentation network table has a production row whose value
  reads "Does not exist", and there is no mainnet chain id, genesis file or validator set.
  `centerchain-docs/docs/start-here/network-status.md:19`, `:21-24`
- No transaction layer to read. `/cosmos/tx/v1beta1/txs?query=...` answers 200 with
  `total: "0"`, so no transaction can be listed or searched, and
  `/cosmos/tx/v1beta1/blocks/{height}` answers 501 Not Implemented, so there is no per-block
  transaction list. Measured 2026-09-30 on `rpc0.test.centerchain.org`.
- No tokenfactory REST. `/centerchain/tokenfactory/v1/params` and
  `/cosmos/tokenfactory/v1/params` both answer 501 Not Implemented with `code 12`. Measured
  2026-09-30. The generated coverage page claims five tokenfactory routes, so the generated
  report and the live endpoint disagree.
- No HTTP faucet service. The faucet exists as an address only.
  `centerchain-docs/docs/start-here/network-status.md:81`
- No gRPC from a browser: a gRPC-web POST answers 404. Measured 2026-09-30.
- No validator run guide and no grant page in the published documentation.
- No compatibility claim for another chain or token standard. The published documentation
  contains none, so neither does this site.
- No dated or expiring permission claim. The documentation calls the swap permission
  time-boxed, but the message definition carries no deadline or expiry field.
- No audit firm, no audit date, no regulatory status, no licence number, no registered company
  address and no jurisdiction of law. Searched 2026-09-30 in the canonical documentation: 0
  matches for each.
- No yield, rate or return figure anywhere on this site.
- `explorer.centerchain.org` and `censcan.com` do not resolve. Measured 2026-09-30: `dig
  +short` returns nothing and `curl` returns 000. Use `/explorer/` on centerchain.org instead.

## What answers today

Base URL `https://rpc0.test.centerchain.org`, shared by RPC and REST on each node. CORS is `*`,
so a browser may read it directly. Measured 2026-09-30:

- `/cosmos/base/tendermint/v1beta1/node_info` 200, reports network `centerchain-testnet-1`
- `/cosmos/base/tendermint/v1beta1/blocks/latest` 200, a live block
- `/cosmos/auth/v1beta1/params` 200
- `/cosmos/bank/v1beta1/supply/by_denom?denom=ucen` 200
- `/cosmos/nft/v1beta1/classes` 200, currently empty
- `/centerchain/liquidity/v1/params` 200, real module parameters
- `/centerchain/liquidity/v1/pools` 200, currently empty
- `/centerchain/income/v1/params` 200
- `/centerchain/income/v1/streams` 200, currently empty

The other node base URLs are `https://rpc1.test.centerchain.org`,
`https://rpc2.test.centerchain.org` and `https://rpc3.test.centerchain.org`
(`centerchain-docs/docs/start-here/network-status.md:59-64`). All four validators run on one
host (`:77`), and the block height changes every block, so query it rather than reading it
from here.
