# Standards and Contracts

*VNX stablecoins are deployed across multiple chains using audited token standards; this is the authoritative contract-address registry for VCHF and VGBP.*

## Overview

VNX issues VCHF and VGBP across multiple blockchains. EVM deployments use the OpenZeppelin contract library; Solana deployments use the Solana Token Program (SPL). Equivalent token standards apply on the remaining chains. Every deployment listed below represents the same underlying claim against VNX's segregated reserves.

## Key benefits

* **Audited token standards.** OpenZeppelin ERC-20 on EVM chains and the Solana SPL Token Program anchor the most-used deployments.
* **One reserve, many chains.** Every VCHF and VGBP deployment points to the same segregated fiat reserve, redeemable at par.
* **Authoritative registry.** This page is the canonical contract-address list — verify here before transacting.

## Use cases

* **Wallet integration** — engineering teams pull verified contract addresses for VCHF (6 chains) and VGBP (4 chains).
* **Compliance verification** — counterparties confirm deployments against the registry before approving an asset.
* **Operational reconciliation** — finance and ops teams cross-check on-chain balances against published VNX deployments.

## Token standards

| Chain family               | Standard             |
| -------------------------- | -------------------- |
| EVM (Ethereum, Base, Celo) | OpenZeppelin ERC-20  |
| Solana                     | SPL Token Program    |
| Stellar                    | Stellar issued asset |
| ICP                        | ICRC token           |

## VCHF contract addresses

| Tezos    | `KT1LssxZqfQtRFv1CRkzX9E9gzap9iFrtWmq`                          |

## VGBP contract addresses

VGBP (British Pound stablecoin, ticker `VGBP`) is deployed on 4 chains.

| Chain    | Address                                        |
| -------- | ---------------------------------------------- |
| Solana   | `5H4voZhzySsVvwVYDAKku8MZGuYBC7cXaBKDPW4YHWW1` |
| Ethereum | `0x34c9c643becd939c950bb9f141e35777559817cb`   |
| Celo     | `0x7aE4265eCFC1F31bc0E112DfCFe3D78E01f4BB7f`   |
| Base     | `0xaeb4bb7debd1e5e82266f7c3b5cff56b3a7bf411`   |

## How it works

Each deployment is a separate ERC-20-equivalent (or chain-native) token contract pointing at the same underlying VNX reserve. Mint and burn operations are gated by VNX's M-of-N multi-confirmation standard, with a minimum of two signatories required for quorum. All deployments share VNX's at-par redemption guarantee against fiat reserves.

## Verification

Customers and integrators should verify a contract address against this page (and where available, against the on-chain explorer linked from each row) before transacting. Addresses found in third-party sources without independent verification should not be trusted.

## Regulatory and risk context

Token standards and deployments are part of VNX's blockchain network risk surface. See [Stablecoin Specific Risks](/vnx-global/institutional/risk/stablecoin-specific-risks.md) for the institutional view, and [Developer overview](/vnx-global/developer/overview.md) for the developer view.
