edgeX is a high-performance decentralized perpetual futures and spot trading platform incubated by Amber Group, combining an off-chain matching engine with on-chain settlement. Its original venue ran on StarkEx zero-knowledge rollups and wound down in August 2026. edgeX V2 is a full rebuild on EDGE Chain, an application-specific Arbitrum rollup that settles to Ethereum, using Circle's CCTP for native USDC deposits and reaching a peak throughput of 300,000 orders per second at sub-100 millisecond order latency.

# edgeX Bridge deposits Methodology

## 1. Overview

edgeX Bridge deposits is calculated as the total USD value of assets held in edgeX Bridge contracts on main chains. Historical capital flows into the original StarkEx L2 venue of edgeX are tracked by this metric. StarkEx L2 balances were credited by these contracts for the first venue, which was wound down in August 2026, leaving residual balances. Capital locked within the early edgeX ecosystem is indicated by these remaining balances. Collateral held on the later USDC venue on EDGE Chain is excluded from this calculation.

## 2. Data sources

- **Blockchain events**: ERC-20 `Transfer` events and native asset transfers associated with edgeX Bridge deposit contracts, covering Ethereum, Arbitrum, and BSC
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Flow extraction and tracking

- **Purpose**: Extract daily token and native asset flows for the designated edgeX Bridge contract addresses
- **Logic**: Daily ERC-20 `Transfer` events and native asset transfers are filtered for the specific edgeX Bridge deposit contract addresses on each chain. For Ethereum, the tracked addresses are `0xc0a1a1e4af873e9a37a0cac37f3ab81152432cc5`, `0xfaae2946e846133af314d1df13684c89fa7d83dd`, and `0x7f861a7db997b4f6e5ef9954a3b5d5b29c463cb2`. For Arbitrum, the tracked addresses are `0xceeed84620e5eb9ab1d6dfc316867d2cda332e41`, `0x6f4836afd5e21edcee9b838c5a4125829ec198d0`, `0x107695630130919cb040b095b9b20511d6e211bb`, and `0x81144d6e7084928830f9694a201e8c1ce6ed0cb2`. For BSC, the tracked address is `0x3eedb0d9c95263778a62081f2a62fc77a392116d`. Inflows and outflows are aggregated daily to determine the net daily flow for each asset.
- **Key fields**: `timestamp`, `account_address`, `token_address`, `amount`

### Component B: Balance aggregation and normalization

- **Purpose**: Calculate the cumulative running balance of each asset held in the edgeX Bridge contracts
- **Logic**: Net daily flows are summed cumulatively over time to establish the running balance of each asset. These raw asset balances are normalized by decimal precision using asset metadata. Balances are carried forward for days without active transfer events to ensure continuous daily coverage.
- **Key fields**: `amount`, `decimals`

### Component C: USD valuation and product tagging

- **Purpose**: Convert asset balances to USD and attribute them to the edgeX Bridge product
- **Logic**: Normalized daily asset balances are multiplied by end-of-day asset prices to calculate the USD value. These values are aggregated by day and chain, and tagged to the edgeX Bridge product. Chain availability filters are applied to align the data with active chain timelines.
- **Key fields**: `price_usd`, `balance`
