Cross-domain bridge

This tutorial drives a GoalBridgeAction through the production bridge adapter chain so a contract on Infrix can dispatch a transaction to a remote chain (Ethereum Sepolia, Cosmos testnet, Bitcoin testnet, Solana devnet, or another VDK-supported chain).

Run the demo

cd examples/kermit-bridge-dispatch
go run .

What it demonstrates

• BRIDGE_SEND admission with the full operator-fixture chain (TrustProfile + bridge:send policy + verify:proof_accept policy + admin role)
• productionExternalBridgeRouter selects the per-chain VDK adapter and signs a real transaction
• The BridgeMessageDispatcher seam carries the canonical BridgeDispatchResult (MessageID + ProofType) through evidence
• Plan compilation produces a BridgeReceipt artifact recorded against the EvidenceLedger

Source

The example main is at examples/kermit-bridge-dispatch/main.go. To run against a different chain, swap the --chain flag (ethereum-sepolia, cosmos-testnet, bitcoin-testnet, solana-devnet).
