# DNA Payment Bridge

Archives DNA x402 micropayment audit events and signed receipts into Liquefy
vaults as verifiable proof artifacts.

This is a bridge, not the payment rail. It consumes exported audit events from
a running DNA x402 server and archives them with bit-perfect vault verification.
Protocol concerns (off-chain balances, disputes, slashing, Solana RPC sequencing)
stay in the upstream `dna-x402` codebase.

## What it does

- Exports DNA payment audit events as Liquefy telemetry (NDJSON)
- Converts signed payment receipts into `liquefy.dna.proof.v1` artifacts
- Carries DNA Guard events (spend blocks, replay alerts, validation failures)
- Packs everything into `.null` vaults with bit-perfect MRTV verification

## Quick start

```bash
python plugins/dna-payment/dna_bridge.py status --server http://localhost:8080
```
