Users sign up for World ID by visiting a Worldcoin Operator and verifying their unique personhood at an Orb. The Orb uses iris biometrics to establish an individual’s unique personhood and then creates a digital World ID, which is stored on the users device using a compatible identity wallet. World App is built on top of Safe's smart contract accounts and also serves as an identity wallet.

Worldcoin is an open source protocol primarily consisting of World ID - a privacy-preserving digital identity and World App - a fully self custodial wallet. Worldcoin was founded by Sam Altman, Alex Blania and Max Novendstern and publicly launched in July 2023.

Worldcoin is currently governed by the Worldcoin Foundation, but intends to decentralize governance over time. Worldcoin's investors include a16z, Multicoin Capital, 1confirmation, CoinFund etc.

# Worldcoin Bridge deposits Methodology

## 1. Overview

Bridge deposits represent the total USD value of tokens held in Worldcoin's bridge deposit addresses on Ethereum. This metric tracks the aggregate value of assets that have been deposited into Worldcoin's bridging infrastructure, providing insight into the protocol's bridging activity and locked value. The calculation focuses on three specific Ethereum addresses that serve as Worldcoin's primary bridge deposit contracts, measuring the combined token balances across these addresses.

## 2. Data sources

The calculation relies on several key data sources:
- **Ethereum blockchain events**: Parsed `Transfer` events from ERC-20 tokens and ETH transfers to track token movements into and out of bridge addresses
- **Token balance data**: Historical balance snapshots and balance change events for the specified bridge addresses
- **End-of-day price feeds**: Token price data used for USD conversion of all held assets
- **Token metadata**: Information about token decimals, symbols, and contract addresses for proper balance calculations
- **Chain availability configuration**: Settings that define which blockchain networks are supported and included in the final output

## 3. Step-by-step calculation

### Component A: Bridge address portfolio tracking
- **Purpose**: Identifies and tracks token balances across Worldcoin's three bridge deposit addresses
- **Logic**: The system monitors three specific Ethereum addresses (`0x470458C91978D2d929704489Ad730DC3E3001113`, `0xd5ec14a83B7d95BE1E2Ac12523e2dEE12Cbeea6C`, `0x153a69e4bb6fedbbaaf463cb982416316c84b2db`) that function as Worldcoin's bridge deposit contracts. For each address, the calculation processes all incoming and outgoing `Transfer` events to maintain running balance totals for each token type. This includes both ERC-20 token transfers and native ETH movements
- **Key fields**: Address identifiers, token contract addresses, transfer amounts (`amount`), transaction timestamps (`timestamp`), and running balance calculations (`balance`)

### Component B: Balance aggregation and USD conversion  
- **Purpose**: Converts individual token balances to USD and aggregates across all bridge addresses
- **Logic**: Token balances from each bridge address are converted to USD using end-of-day price feeds, with proper decimal place corrections applied based on each token's metadata. The system handles various token types including major cryptocurrencies and stablecoins. Balances are then summed across all three bridge addresses to create a unified portfolio value
- **Key fields**: Token balances (`balance`), USD prices from price feeds, decimal-corrected amounts, and aggregated USD values

### Component C: Business metadata and time series processing
- **Purpose**: Adds protocol classification and standardizes the time series format
- **Logic**: The metric is classified with business metadata including market sector as 'blockchains_l2' reflecting Worldcoin's Layer 2 positioning, and business segment as 'blockchain' for the core infrastructure category. The product identifier is set to null as this represents aggregate bridge activity rather than a specific product. Time series data is processed to ensure consistent timestamp grains and proper chronological ordering
- **Key fields**: Market sector classification (`market_sector_id`), business segment (`business_segment_id`), timestamp formatting (`timestamp`, `timestamp_grain`), and chain identifier (`chain_id`)

### Final aggregation
- **Combining components**: Bridge deposits are calculated by summing the USD-converted balances across all three specified bridge addresses, grouped by timestamp, timestamp grain, and chain to create daily aggregate values
- **Currency conversion**: All token balances are converted to USD using end-of-day price feeds, with decimal corrections applied based on each token's specific decimal configuration
- **Time aggregation**: Data is organized by daily timestamp boundaries, with forward-filling applied to handle missing data points and ensure continuous time series representation
- **Final calculation**: The bridge deposits value represents the total USD value of all tokens held across Worldcoin's three bridge deposit addresses at each point in time, providing a comprehensive view of assets locked in the bridging infrastructure
