⛓️Addressing Multi Chain Challenges

Section	Description
Introduction	Extending BRC20 standard for cross-chain compatibility, decentralization, and compatibility with smart contract chains.
Technical Requirements	Custom indexer, destination chain contract, BTC-Relay smart contract for Bitcoin verification.
Use Cases	Facilitates access to decentralized financial protocols, enabling advanced DeFi opportunities.
Protocol	Introduces Bridge-out and Bridge-in operations for token transfer between Bitcoin and destination chain.
Deploy on Destination Chain	Smart contract requirements for minting wrapped tokens based on valid transaction proofs.
Bridge-out	Locks BRC-20 tokens on Bitcoin and mints wrapped tokens on the destination chain.
Bridge-in	Burns wrapped tokens on the destination chain and mints BRC-20 tokens on Bitcoin.
Indexer Behavior	Verifies mint and bridge-in events, updates token balances, and total bridged-out amounts.
