Cross-Chain Stablecoin Support (Multichain)

[soomtochukwu]

Description
The platform uses Stellar USDC. Future support for cross-chain stablecoins (e.g., Celo CUSD, Ethereum USDC, Polygon USDT) requires a cross-chain bridge to allow freelancers and clients to operate asynchronously across varying networks.

Requirements

• Evaluate Wormhole, LayerZero, and Squid Router for EVM ↔ Stellar bridging
• Implement a bridge adapter service that wraps the chosen bridge SDK
• Expose a backend endpoint POST /bridge/to-stellar accepting amount + source chain address
• Display estimated bridge fee and time to the user before confirmation

Acceptance Criteria

• A testnet stablecoin amount successfully bridges to a Stellar Testnet USDC balance from at least two different chains
• Bridge fee estimate is shown to the user before any transaction is signed
• Bridge failure is surfaced as a clear error message (not a silent hang)
