EVM/SOL → BRC Bridging

1. Burn and Event Trigger: A user initiates the bridge by calling the smart contract method that burns tokens and logs an event with the BRC20 wallet address and target blockchain.

2. Event Capture and Validation: The subgraph indexer captures this event, and the backend validates it.

3. Token Transfer Execution: Upon validation, the backend performs the token transfer within the BRC20 network, completing the bridging process.
