Flashbake Registry

Once you have set up your flashbake endpoint, you must register it on-chain.

The Flashbake Registry is an on-chain table associating bakers with their Flashbake endpoint URL.

Any baker can register as a flashbaker by submitting their Flashbake endpoint URL to the contract storage.

To prevent spam, the flashbaker is required to deposit Tez into the contract in order to have their address registered.

Chain	Contract Address	Deposit Amount
Mainnet	KT1PQ21pYv12aUg6tHYvM9rwekYMXUtYGo2a	10 tez
Ghostnet	KT1CWuYkWxZMSq8kA12Kt5NpFGjSRac1Dc4r	1 test tez

• read the registry contract source code.
• explore the registry contract on BCD explorer

How to register as a flashbaker on Mainnet with CLI

To register as a flashbaker, issue the following command:

tezos-client \
  --endpoint https://mainnet.smartpy.io \
  transfer 10 from <YOUR BAKER ADDRESS> to KT1PQ21pYv12aUg6tHYvM9rwekYMXUtYGo2a \
  --entrypoint 'register' \
  --arg '"<YOUR FLASHBAKE_ENDPOINT_URL>"' \
  --burn-cap 0.037

<YOUR_FLASHBAKE_ENDPOINT_URL> should be the Flashbake endpoint relay listener URL. It is typically https://<address>:<port>/flashbake/bundle, where the relay listener of your Flashbake endpoint is publicly accessible on <address>:<port>.

To unregister and get your bond back:

tezos-client \
  --endpoint https://mainnet.smartpy.io \
  transfer 0 from <YOUR BAKER ADDRESS> to KT1PQ21pYv12aUg6tHYvM9rwekYMXUtYGo2a \
  --entrypoint 'unregister'

To update your flashbake endpoint address, you must unregister then re-register.

How to register as a flashbaker on Mainnet using Better Call Dev

Open the Registry Contract Interaction Page.

The "register" entrypoint is already selected. Set your Flashbake Endpoint Address (https://<address>:<port>/flashbake/bundle) as the "register" string parameter.

Expend the "Optional settings" menu. Under "Amount" put "10000000" (10,000,000 mutez = 10 tez).

Then press "Execute" and select "Wallet". Your baker address must be connected with Beacon Wallet. Please exercise caution when signing anything with your baker address.

Confirm the operation on your wallet.

Multi-sig setup

The registry contract on Ghostnet is controlled by a multi-signature. The only action allowed by the multi-signature setup is to change the bond amount required. This multi-signature can also be upgraded to another set of accounts, or revoked altogether to make the registry immutable and trustless.

The current set of participants to the multi-signature setup are:
