Synapse allows users to send tokens from one chain to another almost immediately by using AMMs deployed across 16+ EVM and non-EVM blockchains. 

Synapse is a cross-chain liquidity network that enables fully non-custodial transfers between EVM and non-EVM compatible chains and L2 systems. Synapse was launched in 2021.

SYN tokenholders own and govern the protocol. They currently take a cut of the transaction fees paid by the users (revenue). Synapse’s investors include CMS Holdings, Alameda Research, Primitive Ventures, etc.

# Synapse Active users (daily) Methodology

## 1. Overview

The Synapse User DAU (Daily Active Users) metric measures the number of unique addresses that perform any cross-chain bridge operation through the Synapse protocol on a given day. This metric captures user activity across Synapse's multi-chain bridge infrastructure, counting any address that initiates or receives tokens through bridge transactions as an active user. The calculation aggregates activity across eight supported blockchains to provide a comprehensive view of daily protocol usage.

## 2. Data sources

- **Synapse Bridge contract events**: Parsed smart contract events from Synapse Bridge contracts deployed on Ethereum, Arbitrum, Avalanche, Base, Fantom, BSC, Optimism, and Polygon blockchains
- **CCTP contract events**: Parsed Circle Cross-Chain Transfer Protocol events for enhanced cross-chain functionality on Ethereum, Arbitrum, Avalanche, and Optimism
- **Blockchain transaction data**: Transaction timestamps and metadata from all supported blockchain networks to provide temporal context for user activity

## 3. Step-by-step calculation

### Component A: Cross-chain bridge event collection
- **Purpose**: Captures all user interactions with Synapse bridge contracts across supported blockchains
- **Logic**: Collects parsed smart contract events from Synapse Bridge contracts on eight different blockchains. The system monitors multiple event types including `TokenMint`, `TokenMintAndSwap`, `TokenWithdraw`, `TokenWithdrawAndRemove`, `TokenDepositAndSwap`, `TokenRedeemAndSwap`, `TokenRedeemAndRemove`, `TokenRedeem`, `TokenRedeemV2`, and `TokenDeposit` events. Additionally, on chains that support Circle's CCTP, the system captures `CircleRequestFulfilled` and `CircleRequestSent` events for enhanced cross-chain transfer capabilities.
- **Key fields**: Event captures `block_timestamp` for temporal analysis, `transaction_hash` for deduplication, and user address fields that vary by event type (`to`, `recipient`, or `sender` parameters)

### Component B: User address extraction and standardization
- **Purpose**: Extracts unique user addresses from various bridge event parameters and standardizes the data structure
- **Logic**: Extracts user addresses from different event parameter fields depending on the specific event type. Most Synapse Bridge events use the `to` parameter to identify the recipient address, while CCTP events use `recipient` for fulfilled requests and `sender` for initiated requests. All extracted addresses are classified with standardized metadata including user type as 'Trader', market sector as 'bridges', and business segment as 'amm'. The system preserves chain identification to maintain cross-chain visibility.
- **Key fields**: Standardized `user_address`, `chain` identifier, `user_type`, `market_sector_id`, `business_segment_id`, and temporal `block_timestamp`

### Final aggregation
- **Combining components**: All standardized user events from different chains and event types are combined into a unified dataset
- **Currency conversion**: No currency conversion required as this metric counts addresses rather than monetary values
- **Time aggregation**: Block timestamps are truncated to daily boundaries using day-level granularity. The system counts distinct user addresses within each daily time window per chain
- **Final calculation**: The final DAU metric represents the count of unique addresses (`user_dau`) that performed any bridge operation on each specific day and chain combination. Chain availability filtering ensures data quality by excluding periods where blockchain data may be incomplete or unreliable
