## Contract explorer

To make reviews or simple source code surfing easier, i added the contracts to the L2BEAT disco contract explorer, where you can see the old (current) contracts, the payload and the new contracts, with some added descriptions and the source code nearby. [Check it out here](https://disco.l2beat.com/ui/p/aztecnetwork-alphapayload). I would recommend you to give the new contracts different colours than the old ones.

 ![aztec alpha in disco ui](https://europe1.discourse-cdn.com/flex013/uploads/aztec/original/2X/6/69a496549f497bc069cc52688384c60cd4890e12.png)

## Sequencer Signaling

(recommended: environment variable)

To signal support for the Alpha payload persistently (survives node restarts), set the sequencer payload address via the environment variable:

```auto
# Add this to your .env (or docker-compose environment) and restart the node
GOVERNANCE_PROPOSER_PAYLOAD_ADDRESS=0x780523FBa95e4Be0Fa09DA0fff5Fab3aBAE7B58e

```

Very cool. And very useful. Going to pick up a lot form this in terms of understanding and examples for our [Aztec explorer](https://validatorinfo.com/networks/aztec/overview)

The Aztec Labs team has thoroughly reviewed this proposal and found the deployed contracts to match what was made available to the community.

**Bytecode verification**

Each of the deployed contracts was verified using `forge verify-bytecode` against Etherscan. All contracts returned either a full match or a partial match. Partial matches were expected and they are due to differences in the metadata hash.

**Payload actions**

The payload executes exactly the six actions described in the proposal:

1. Register the new Rollup in the Registry (making it canonical)
2. Register the new Rollup in the GSE
3. Enable rewards claiming on the new Rollup
4. Update the Escape Hatch to the newly deployed contract
5. Migrate claimable rewards from the old FlushRewarder to the new one
6. Update the Governance execution delay to 30 days

**Contract configuration**

Configuration values of the deployed contracts were confirmed to match what was shared with the community.

**Testnet validation**

The same version of the protocol is live on [testnet](https://testnet.dashtec.xyz/) as release [4.1.0-rc.2](https://github.com/AztecProtocol/aztec-packages/tree/v4.1.0-rc.2) on the aztec-packages repository, producing blocks, proofs, and attestations. It will be promoted to a stable release `4.1.1` prior to the execution of the Alpha upgrade.

**Security**

For context on the security model and trust assumptions during the Alpha phase, please refer to this post: [Alpha Network Security: What to Expect.](https://aztec.network/blog/alpha-network-security-what-to-expect)
