Building a Cross-Chain Bridge API for RustChain: RIP-305 Track C

Building a Cross-Chain Bridge API for RustChain: RIP-305 Track C RustChain is a Proof-of-Antiquity blockchain where vintage hardware mines real crypto. But until now, there was no way to move RTC (RustChain's native token) onto other chains. Today I built the bridge API that makes it possible — connecting RTC to Solana and Base L2. What Is RIP-305? RIP-305 is RustChain's cross-chain airdrop protocol. It distributes 50,000 wrapped RTC (wRTC) across two target chains: Track A : wRTC as a Solana SPL token (30,000 wRTC) Track B : wRTC as a Base ERC-20 token (20,000 wRTC) Track C : The bridge API connecting them ← this post Track D : An airdrop claim page Track C is where the magic happens. Without a bridge API, the tokens on Solana and Base would just be isolated assets with no connection to the actual RTC ecosystem. Architecture: Phase 1 (Admin-Controlled) Phase 1 is intentionally simple and trustworthy. Rather than building a complex trustless bridge with cross-chain message passing (whi
