# Deployment

This section documents the public Constant Finance deployment on Ethereum Sepolia. It is a dated testnet snapshot, not a statement that Constant Finance is deployed on Ethereum Mainnet.

## Current Snapshot

| Item                      | Value                                     |
| ------------------------- | ----------------------------------------- |
| Network                   | Ethereum Sepolia                          |
| Chain ID                  | `11155111`                                |
| Core deployment completed | August 31, 2026                           |
| Deployment blocks         | `11600264`–`11600296`                     |
| Deployment transactions   | `30/30` successful                        |
| Post-deployment check     | Read-only configuration smoke test passed |

The smoke test confirmed contract code, dependency addresses, ownership, price-feed configuration, collateral parameters, Constant NFT settings, and Gateway routing. It did not, on its own, prove that every possible user flow had completed end to end.

## Documented Product Surface

The deployed Gateway routes the protocol operations described in this guide:

* Basic Position creation and repayment;
* debt refinance;
* Order cancellation and capacity synchronization; and
* callback dispatch used by the active refinance path.

The oracle stack values the supported ERC-20 assets and Uniswap V3 LP NFT collateral. Position contracts handle collateral management, repayment synchronization, closing, health checks, and permissionless liquidation.

## Testnet Boundary

* Faucet tokens do not have mainnet economic value.
* Some price feeds are controlled test feeds.
* The accepted price age is intentionally broad for this test environment.
* At the deployment snapshot, the configured test Swap Router held no output-token inventory. This documentation therefore does not present swap-dependent repayment or liquidation liquidity as operationally available.
* Contract addresses and settings should always be read as a versioned deployment snapshot.

## Pages

* [Ethereum Sepolia](/docs/introduction/deployment/ethereum-sepolia.md) lists public test assets, feeds, and protocol contracts.
* [Risk Configuration](/docs/introduction/deployment/risk-configuration.md) records the collateral and fee parameters bound to new Positions through the deployed Config.
