List of audit links if any:

No external audits published yet – core contracts are based on widely used, open-source EVM standards (Uniswap-style AMM + DPoS staking). Formal audits are planned as TVL grows.

Treasury Addresses (if the protocol has treasury):

Treasury is held in a multisig on GRX Chain, used for ecosystem incentives, listings and development.
Addresses can be shared privately with the DefiLlama team if required.

Short Description (to be shown on DefiLlama):

GRX Chain is an EVM-compatible Delegated Proof of Stake (DPoS) blockchain with GRX as the native gas, staking and governance asset. The ecosystem includes GRXswap, an AMM DEX on GRX Chain, and deep integration with the GroveX exchange as a primary fiat and liquidity gateway. GRX Chain focuses on DeFi, on-chain trading, payments and Web3 applications, with a fixed 10M GRX supply and a deflationary fee-burn model.

Token address and ticker if any:

• Native token (L1 gas / staking):
  GRX – native asset (no ERC-20 contract)

• Wrapped token:
  WGRX – 0x45C7287F897B3A79Cd3f6e4F14B4CE568f023bD5

Category:

Chain (L1)

Oracle Provider(s):

DEX TWAP / on-chain pricing from GRXswap pools.
No external oracle providers (Chainlink, Band, etc.) are used for TVL calculations.

---

Implementation Details:

• TVL is calculated from GRXswap AMM liquidity pools using on-chain data.
• GRX is priced from the main GRX/USDT pool.
• Other tokens priced via deepest USDT / WGRX / GRX pairs.
• Optional TWAP (AMM-based) applied to reduce price manipulation.
• USD values derived from on-chain pricing and aggregated.
• Cross-check with public stats dashboard: https://grxstats.grxscan.io/stats

forkedFrom:

• Core blockchain: custom EVM-compatible L1
• GRXswap AMM: based on Uniswap V2 architecture with modifications

methodology (what is counted as TVL & how it's calculated):

What counts as TVL

• Liquidity locked in all GRXswap pools (both sides of each pair)
• GRX tokens staked in DPoS validator + delegator contracts

Excluded:

• CEX balances
• Off-chain or custodial holdings

---

How TVL is calculated

1. Query GRXswap factory contract for all LP pairs.

2. Fetch reserves for each pool on GRX Chain.

3. Price tokens:

   • GRX priced via GRX/USDT pool
   • USDT assumed $1
   • Other tokens priced from their deepest USDT/WGRX/GRX pairs
   • Optional TWAP used to smooth volatility

4. Convert token reserves to USD and sum all pools = DEX TVL

5. Query staking contracts for total staked GRX

6. Convert staked GRX to USD using on-chain pricing

7. Add DEX TVL + Staking TVL

Does this project have a referral program?

The GRX Chain protocol does not have a referral program.
GroveX (centralized exchange) has a referral program, but this is not part of on-chain TVL.

The adapter at projects/grxswap exports TVL:

grx                       0.00

total                    0.00

I dont think explicit RPC is required?

Where is this USDT bridged from? Where is the collateral backing held?
