Make sure to have Leo installed. For details, follow this guide. Alternatively, ensure that Leo is up to date: leo update.

Then, run:

leo build

In this repository, using the basic_bank.leo as an example, the goal is to use tyron.leo/is_signer() instead of a hardcoded address of the bank to verify that the order comes from the bank indeed.

Changing:

assert_eq(self.caller, aleo1t0uer3jgtsgmx5tq6x6f9ecu8tr57rzzfnc2dgmcqldceal0ls9qf6st7a);

For:

tyron.leo/is_signer();

And more importantly, the signer is secured by Tyron's social recovery.

• Initialise the TyronSSI account by setting the address of the signer.

• Verify that the call comes from the signer's EOA.

• Add new guardians.

• Remove guardians.

• Add a guardian's signature.

• Execute social recovery to set up a new signer. The number of recorded signatures must be greater or equal to the threshold (absolute majority, i.e. half plus one).
