Rolle	Pflicht	Beschreibung
Blockchain Developer		Understands cross-chain bridge fundamentals: lock-and-mint, burn-and-release patterns, and relay mechanisms. Follows team conventions for integrating bridge SDKs and testing cross-chain token transfers on testnets.
Smart Contract Developer		Understands cross-chain bridge fundamentals from smart contract perspective: bridge contract interfaces, message passing protocols, and token wrapping mechanics. Follows team patterns for implementing bridgeable token contracts.

Rolle	Pflicht	Beschreibung
Blockchain Developer		Independently develops with Cross-Chain Bridges in Hardhat/Foundry. Conducts basic audits. Optimizes gas.
Smart Contract Developer		Independently develops with Cross-Chain Bridges in Hardhat/Foundry/OpenZeppelin. Conducts basic audits. Optimizes gas.

Rolle	Pflicht	Beschreibung
Blockchain Developer	Pflicht	Designs cross-chain bridge architecture: validator sets, optimistic vs ZK verification, and relay infrastructure. Conducts security analysis of bridge protocols for MEV protection and double-spending prevention. Mentors team on interoperability patterns.
Smart Contract Developer	Pflicht	Designs cross-chain smart contract systems: Chainlink CCIP integration, LayerZero messaging, and Hyperlane interchain contracts. Conducts security audits of bridge contract logic and implements replay protection mechanisms.

Rolle	Pflicht	Beschreibung
Blockchain Developer	Pflicht	Defines cross-chain product architecture: bridge selection criteria, multi-chain deployment strategy, and interoperability governance. Establishes security standards for bridge operations and coordinates cross-chain integration testing.
Smart Contract Developer	Pflicht	Defines cross-chain smart contract architecture: message passing standards, cross-chain state management, and bridge contract upgrade governance. Establishes security audit requirements for interchain protocol interactions.

Rolle	Pflicht	Beschreibung
Blockchain Developer	Pflicht	Defines organizational cross-chain strategy: multi-chain architecture vision, interoperability protocol selection, and ecosystem positioning. Evaluates emerging standards (IBC, XCMP, CCIP) and shapes company-wide cross-chain technology roadmap.
Smart Contract Developer	Pflicht	Defines organizational cross-chain smart contract strategy: interoperability standards, multi-chain contract deployment frameworks, and security certification processes. Shapes enterprise vision for cross-chain DeFi and protocol composability.
